WORKING PRINCIPLE
VARIABLE AIRFLOW RECTANGULAR REGULATORS
WORKING PRINCIPLE “INDEPENDENT PRESSURE”
The regulation of the air flow is made by a dynamic pressure control system that can guaranty "the initial independence of the pressure". In so doing, all the requested air flow variations will not disturb the other air flows of other uses.The control system is comprised of the following elements:- Air flow measuring element- Regulation element (the air flow regulator) that receives actual information relative to the measurement of the flow of air and to the request from the room.- This regulator analyses the difference between the true measurement and that needed in the room so as to transmit a command to a specific motorised unit (the damper) that acts on the flow of air so as to obtain the final requested value by closing in the event of excess and opening in the event of lack of air.- In the case of variable flow, the set point of the flow is variable from a maximum to a minimum value in relation to the regulation of the temperature;- The system will always work so as to work the requested air flow in that moment to satisfy the room requirements.
COMMAND SIGNALS USED
When ordering, is necessary to specify the type of signal that will be used for the adjustment.The used signals are- Signal 0V-10V;- Signal 0V-10V with separate control of total closure;- Signal 2V-10V;- Signal 2V-10V with separate control of total closure;- Signal 2V-10V with total closure to 0V.
ENVIRONMENTS IN PRESSURE OR DEPRESSION
In this type of environments it is possible to control the adjustment in recovery via a differential pressure sensor to ensure the overpressure or depression prescribed independently of the flow and the presence of other air outlet, for example in the presence of hoods or frequent opening of the door of access to the room.

Regulator calibrationFor the calibration of the regulator CL-VRR it will be necessary to indicate the maximum and minimum flows requested for the intended use.
The maximum air flow must be between the two values indicated in the table.The minimum air flow must be greater or equal to the value indicated in the table
Installation arrangementsfor a correct reading of the performances and for a air flow tolerance of 5%, it is necessary at the source to supply a straight section of duct of a length equal to three times the dimension of the larger size of the regulator. In the opposite case, the air flow may be affected a variation between 10% and 20% in comparison to the calibrated value.
Leakages with closed damper:The gasket, fitted on the perimeter of the damper, maintains a level of leakages through the damper below 0,1% of the nominal flow, with a maximum pressure of 1000 Pa.The shut off is certified to EN 1751-EN 1886 standard.

CL-VCC CL-VCL SERIESWORKING PRINCIPLES
VARIABLE AIR FLOW UNITS
WORKING PRINCIPLE “INDEPENDENT PRESSURE”
The regulation of the air flow is made by a dynamic pressure control system that can guaranty "the initial independence of the pressure". In so doing, all the requested air flow variations will not disturb the other air flows of other uses.The control system is comprised of the following elements:- Air flow measuring element - Regulation element (the air flow regulator) that receives actual information relative to the measurement of the flow of air and to the request from the room.- This regulator analyses the difference between the true measurement and that needed in the room so as to transmit a command to a specific motorised unit (the damper) that acts on the flow of air so as to obtain the final requested value by closing in the event of excess and opening in the event of lack of air.- In the case of variable flow, the set point of the flow is variable from a maximum to a minimum value in relation to the regulation of the temperature;- The system will always work so as to work the requested air flow in that moment to satisfy the room requirements.
COMMAND SIGNALS USED
When ordering, you must specify the type of signal that will be used for the adjustment.The signals used are- Signal 0V-10V;- Signal 0V-10V with separate control of total closure;- Signal 2V-10V;- Signal 2V-10V with separate control of total closure;- Signal 2V-10V with total closure to 0V.
ENVIRONMENTS IN PRESSURE OR DEPRESSION
In this type of environments it is possible to control the adjustment in extraction via a differential pressure sensor to ensure the overpressure or depression prescribed independently of the flow and the presence of other air outlet, for example in the presence of hoods or frequent opening of the door for access to the room

Regulator calibration and choice of motor
For the calibration of the CL-VCC and CL-VCL regulators, it will be necessary to indicate the maximum and minimum flows requested for the intended use.
The maximum air flow must be between the two values indicated in the table.The minimum air flow must be greater or equal to the value indicated in the table
Furthermore, it will be necessary to indicate the signal given from the sensor of the room temperature; 0-10V, 2-10V, three point or other.When necessary, it will be necessary to indicate the side on which it is required to install the controls in relation to the flow of air. In the absence of this information, the controls will be fitted on the right hand side in relation to the direction of the flow of air.
Installation conditions:For a correct reading of the performances and for a air flow tolerance of 5%, it is necessary at the source to supply a straight section of duct of a length equal to two to three times the dimension of the diameter of the regulator. In the opposite

DC-BAH SERIES
COILS FOR VARIABLE AIR FLOW UNITS
OVERVIEW
Overview:The DC-BAH series of heating coils are water-air heat exchangers. They are used at the end of the variable air flow boxes to obtain the heating of the injected air in the room.
Technical characteristics:The DC-BAH series heating coils are comprised of:1) supporting structure in galvanized steel;2) blades or pack of blades3) water connections4) water release valve5) drainage tap6) protective arch7) collectorThe symmetric structure of the coil allows for fitting with connections on the right or left side.
Uses:The DC-BAH series heating coils are used solely with the variable air flow boxes so as to maintain the best possible comfort heat levels, not only acting on the air flow, but also on the temperature of the injected air.

DC-BAHFITTING
Fitting mode:The DC-BAH series heating batteries are usually fitted at the bottom of the CL-VCL o CL-VCC series regulation boxes.The box silencers house four filtering inserts M8, where as the batteries house four holes Ø10 for the screws. The use of washers is advised.
Fitting position:The water will always have to enter from the lowest inlet and exit from the highest. The batteries can be made with the water connections on the left of right in relation to the air flow direction. If this is not indicated, they will be made with the connections on the right side.In correctly fitted models the connection for the exit will be the closest to the air entry side. The incorrect fitting of the battery entails a performance reduction of the heat exchange.
Precautions: It is advisable to interject a suitable gasket between the box and the battery to eliminate air leaks.Great care should be taken in handling the battery as the blades is composed of very thin blades easily bendable.Once filled, it is recommended to remove all remaing air by acting on the valve present on the higher duct.If it is necessary to dismantle the battery, it is possible to empty is using the valve on the bottom duct.

RECTANGULAR CONSTANT AIR FLOW REGULATORS AT-RPR
SERIESOVERVIEW
Overview:the AT-RPR series of constant air flow regulators are used to automatically regulate the flow in rectangular ducts at a fixed capacity.The scope is to maintain the nominal value of the constant air capacity, continuously and independently from the pressure variations in the duct.
Working principle:The constant air flow regulator works by means of a slidable asymmetric and angled plate that guaranties a sensitive response even at low air flows.
Pressure, precision and purpose:The regulator efficiently operates from a minimum pressure different, which depends on the air speed (see diagram 1), up to a maximum pressure difference of 1,000 Pa.The general variation in the air flow is included within a ±10% tolerance. If the air speed is less than 4 m/s or if the regulator is installed horizontally, the variations can be higher than those indicated.This also occurs when the air speed profile is not uniform or is distorted by curves edges bottle necks or dirt
AT-RPR : dimensions and
is distorted by curves, edges, bottle necks or dirt.
Temperature:The control system operated within a temperature range of between -30 °C and +100 °C. A special heat resistant version can withstand temperatures up to 250 °C (300 °C for short periods) and is available on request.For air flow controllers with electric or pneumatic actuators. it will be necessary to take into account the operational temperature range of the actuators themselves.
Construction:The control plate is supported by two slidable buffers made in PTFE that do not require maintenance. The pneumatic dampers avoid vibrations and oscillations of the control plate and guaranty a sensible response behaviour and precise control.
Specifications:- Self regulating, constant air flow regulator.- Factory presetting to customer requested value- Manual setting of the air flow through the calibration device.- Variable base and height, length constant at 385 mm- Base value between 150 mm and 600 mm- Heights between 150 mm and 300 mm- The base must be between the value of the height and its double (H � W � 2H)- Fixing through 4 30 mm holes on flanges

SERIESTECHNICAL SPECIFICATIONS
Installation:The precise balancing of the control plate by means of a counter-weight, guaranties an exact control in any installation. It is recommended that the front air speed profile be as much as possible undisturbed because possible distortions (asymmetric to the flow of air on entry, bottle necks and edges) can have negative effects on the response and control.
Calibration:The air flow regulators can be supplied either with setting made by the customer or precalibrated in the factory using customer requested values. By means of a 2mm special key, the air flow can easily be set or reset within the range of the corresponding scale by the customer directly.On request, the nominal value of the air flow can also be set by means of the pneumatic or electric actuator.
Sizing:Before sizing a duct system and choosing a certain air flow regulator, it is necessary to consider that the air speed inside the ducts should is between 3 and 10 m/s.
The ducts directly before and after of the air flow regulator should have the same dimensions (base and height) of the regulator itself. As a nominal or reference value, it is recommended an average air speed of about 6.5 m/s.
Insulation:The air flow regulator can be supplied with a thermal and acoustic insulation of 30 mm. For insulations made by the customer, these must be extended to the regulation device or to the electric or pneumatic actuator. In this case it will be the client themselves to specify the thickness of the insulation.
Note on the installation:IN conformity to DIN 1946T2, it is necessary to foresee the accessibility to the constant air flow regulator and to the duct systems to allow maintenance and calibration.

CIRCULAR AIR FLOW REGULATORSAT-RPC SERIES
OVERVIEW
Overview:The AT-RPC series air flow regulators are independent control units that work without absorbing any external power. These regulators can be considered as self regulating duct dampers able to supply a flow of air requested independently from the variations of pressures in the system. As a result, the control system guarantees the balancing requirements of the system and ensures a constant air flow. Variable airflow models are available with electric or pneumatic actuators.
Working principle :The air flow control system works by means of a free control plate, supported by two buffers in PTFE and connected to a calibrated spring. The aerodynamic forces contrast the force of the spring e push on the plate to the point of moving it into a position that in the end controls the flow of air.
Pressure, precision and purpose:The control system work reliably starting from a minimum pressure difference which depends on the air speed (see diagram 1) up to a maximum pressure

IF the air speed is below 4 m/s or the control system is installed horizontally, the variations may be greater that those indicated. This occurs even when the profile of the air speed is not uniform or is distorted by curves, edges or bottle necks. Furthermore, the recommended air speed is around 4.5 m/s and should not be below 2.7 m/s.
Temperature:The control system operated within a temperature range of between -30 °C and +100 °C. A special heat resistant version can withstand temperatures up to 250 °C (300 °C for short periods) and is available on request.For air flow controllers with electric or pneumatic actuators. it will be necessary to take into account the operational temperature range of the actuators themselves.

THECHNICAL SPECIFICATIONS
Construction:The shell of the control system is in galvanized steel and plate laser welded without deformations. The smooth surface of the casing allows the insertion of calibrated and shaped terminal connections with a rubber circular gasket. The air tight system is patented and offers various advantages, such as rigidity, easy fitting and removing, resulting in reduced installation costs.In addition and on request, the control system is available with a new type of fixing with a screwless flange. This type of fixing facilitates the maintenance and the work through the removal of the closing rings placed at the extremities without the need or dismantling the complete duct. The control plate is supported by buffers in PTFE and equipped with an actuator to avoid any possible oscillation of the plate.The control system is also available on request in stainless steel or with a PUR coating or in different RAL colours.
Installation and calibration:The control system can be used in supply or extraction ducts, in high or low pressure ventilation systems. Both vertical and horizontal installations are possible as a result of the exact balancing of the control plate.All controls can be calibrated for the air flow requested, directly in the factory. The manually calibrated control system can be easily set and reset directly by the customer.Any working value can be chosen as long as it is with the operating range of the control system.
Insulation:On request, the control may be supplied with insulation of 25 or 50 mm thickness to reduce the noise or heat dispersion.

CONSTANT AIR FLOW REGULATORSAT-KVR SERIES
OVERVIEW
AT-KVR : dimensioni e costruzioneOverview :The AT-KVR series constant air flow regulators are independent control units that work without absorbing any external power. These regulators are manufacture in PVC in fire class M1. They guarantee the flow of air within a range of pressure loss between 50 Pa and 200 Pa and can be used up to temperatures of 60 °C.
The AT-KVR units are composed of a PVC envelope with a regulation valve also in PVC together with a spring and a small piston.The request air flow must be indicated when ordering.

DOUBLE DUCT VARIABLE AIR FLOW CONTROLLERS CL-VCD
SERIESOVERVIEW
Overview :Variable air flow controllers series CL-VCD are air flow regulation units that allow the mixing of hot and cold primary air to obtain the ideal temperature of the air supplied maintaining the continuous control of the air quality in variable air flow systems.The complete closure is certified according to EN 1751-EN 1886 standards.
Technical characteristics:The double duct controller units type CL-VCD include:- galvanized steel casing with base supports for fitting on site using hanging ties;- circular connection for cold air with dynamic �p probe driven by an electrical motor for measuring and regulation in relation to the requirement of the room itself;- circular connection with damper driven by electrical regulation motor for the regulation and maintenance of the air flow in relation to the requirement of the room itself;- rectangular exit on the low speed side with dynamic �p probe for measuring the total supplied air flow;- silencer section with sound absorbing rock wool material, covered with a black protective film resistant to fire class M0
Tender description : Double duct variable air flow supply control unit, CL-VCD type sold by MP3 Srl, made of galvanized steel complete with differential pressure sensor, air flow regulators and actuators.
Accessories : - additional silencer;- double casing;- equalising net to be installed to the entry point to better distribute the air flow;- micro stretched protection net of noise absorbing material; Other coatings, also in glass fibre, to be chosen at the request stage.
Models :With motors:- Siemens GDB 181.1/E3/MP;- Belimo NMV-D3-MP; - Belimo LMV-D3-MP; - Belimo NM24AV + reg. VRD3;- altre motorizzazioni da concordare in sede d’offerta.Possibility of interfacing with extraction VAV units to guarantee positive or negative pressures in relation to the usecovered with a black protective film, resistant to fire, class M0.
Applications : The CL-VCD series are used to supply a variable air flow to the area to be conditioned in relation to the variation of the its thermal loads to maintain the maximum thermal comfort conditions.Differently to single duct units, the ideal air temperature is obtained by mixing hot and cold air instead of regulation the power supply of the pre heating coil.The auto generated irradiated noise tests have been carried out according to EN ISO 3741 standard.
guarantee positive or negative pressures in relation to the use of the room.The units are normally supplied complete with actuators calibrated on our premises according to customer requests. For request of units without actuators, which will need to be installed anyway by the customer on site, MP3 can not guarantee in any way the correct working of the apparatus.

AIR SUPPLY SECTIONThe temperature sensor E adjusts the cold air flow using an electrical signal.The cold air flow is kept independent of the conditions upstream through the pressure differential probe A, which, using the transducer B emits a signal compared with the control C with the room temperature sensor E. ON the basis of the comparison between the two signals, the controller C modulates the opening of the cold air supply damper through servomotor D.The total flow of air into the room is detected by the differential pressure probe F which through the transducer G emits a signal to regulator H using the servomotor I modulating the opening of the damper for the hot air supply.
AIR EXTRACTION SECTIONThe pressure differential probe L and through transducer M emits a signal proportional to the total extraction air supply compared with the regulator N with the proportional signal tot the total supply air flow emitted from regulator H. on the basis of a comparison between the two signals, controller H modulates the opening of the extraction damper through servomotor P.
This procedure will allow to always keep the environment in desired pressure conditions, which can be equal, greater or less than the atmospheric pressure external according to the type of activities within the environment itself.

Regulator calibration and servomotor selection
For the calibration of the CL-VCD unit the maximum and minimum air flows will need to be indicated for the specific application.
These air flows will need to be included in the table below.
For any supplies without engine, which will nevertheless be applied and calibrated by the customer, MP3 can not guarantee in any way the proper operation within the environment itself.
Conditions of installationFor a correct reading of pressures and for a air flow tolerance of 5%, upstream section of straight channel of length equal to 2/3 times the size of the diameter of the regulator should be installed. in the opposite case, the air flow may suffer variations between 10% and 20% compared to the calibrated value.
Pressure losses with closed damper:The seal is fitted in the perimeter of the damper, it maintains a level of pressure losses below 0.1% of the nominal air flow,, with a maximum pressure of 1000 Pa.The air seal is certified according to EN 1751 EN-1886.
