Flooded Water Cooled Screw ChillerFOCSWATER.C Series460-3400kW (130-970 Tons)
FOCSWATER.CWater cooled screw chiller
Multiple applicationsStandard chilled water applied for HVAC system;By adopting brine or glycol solution, the outlet temperature of evaporator can be in the range of -8~15℃, either for ice storage application or for industrial process purpose;Heat recovery function is optional.
Safety of electrical devicesInner structure of electrical cabinet, electrical components and circuit layout are designed according to EN60204-1/IEC204-1 standard. Controlling power is separated from main power by transformer so as to protect from impact and interfere of electrical current. The power section uses a bar-type distribution system and interlock-door mains isolator for safety and reliability. Each load of compressor is equipped with its own overload protector, fuse and contactor. Electric elements are with features of excellent insulation, dust-proof and humidity proof, and suitable for various inferior environments. Electrical system of the unit is in compliance with EMC code.

CompressorsSemi-hermetic screw compressors specifically designed for R134a & flooded evaporation application, featuring in high efficiency and energy saving.Precisely manufacturing technology and least moving component result in rel iable performance and simple maintenance.The compressor, w i th i t s own capac i t y regu la t i ng electromagnet ic valve and sl ide valve together wi th Climaveneta's micro-computer controlling system, can adjust load output automatically according to the requirement of processing, realize 10~100% stepless of precision variable adjustment and reduce power consumption.
Dedicated Flooded Evaporator/CondenserFlooded evaporator/condenser with integral rippled tube are modified to enhance the initiation of nucleate boiling sites and surface area, improving turbulent flow, resulting in increasingly overall heat transfer coefficient and high unit efficiency.The evaporator is characterized by low pressure drops on both the gas side and the water side. The level of refrigerant inside the flooded evaporator is guaranteed by dedicate sensor level and modulating electronic valve.Single circuit design even for multiple compressor improves unit part load efficiency.Chilled water inside tube make maintanence work convinient and simple.
Maximum ReliabilityDesign, manufacturing, testing comply with the several regulations such as AHRI, EN, UNI, JIS and Chinese standard GB/T18430.1.The built-in 3 stages oil separator and external efficient second separator ensure the constant presence of oil inside. Besides, unique device is designed by CLIMAVENETA dedicated to guaranty oil return.The unit has been charged with R134a and oil before shipped out from factory, and tested and inspected strictly according to UNI9218 standard. Only after water and electrical power being connected on site, the unit can be put into production for providing chilled water.
Optimized and Efficient PartsThe electronic valve is adopted to grant the ideal operation of the evaporator in all conditions. The complete flooding of tubes is granted with a sophisticated detection of the refrigerant level in the heat exchangers. The fast processing of the acquired data allow a quick, fluctuation-free regulation, and therefore a highly accurate adjustment to the swings of load and ambient conditions.Economizer has been adopted to improve unit efficiency.

● Friendly interfaceFully computer-controlled with no necessity of person duty;Objective user operational panel with multiple windows clearly displaying parameters of different categories;Graphical symbol inputting and displaying with convenient operation;Convenient adjusting and setting of data input through menu and fast key combination.● Control functions of the unitThe unit adopts W3000 intelligent microcomputer control system with setting, adjusting and controlling functions, such as: stepless regulation of cooling capacity; inlet/outlet chilled water temperature regulation; Starting, unloading and stopping functions of compressor; starting delay function of compressor; time limiting function of each hour start of the compressor; operation timing function of compressor; and running time balance function of compressor.
● Protecting and alarming functions of unitSelf-test when power on to avoid running with problem.Three lever password protection to prevent from mal-operation of persons without authorization.Overload, overheat and overvoltage protection and alarming of compressor; high discharge temperature protection and alarming of compressor.Water antifreeze protection, antifouling protection and alarming of evaporator;Protection and alarming of over high and low chilled water and cooling water temperature; protection and alarming of low water flow;Protection and alarming of low and high pressure of refrigeration system, and alarming of refrigerant leakage. ● Fault processing functionAutomatically functioning protection of acousto-optic alarming, load reducing of compressor, stopping of compressor and stopping of unit according to each fault grade. Automatically identifying fault and instructing fault category.Automatically recording fault with record capacity as much as 400 faults.Black box function which automatically record on-site state and all data of fatal fault for providing analyzing data.
Group Control DeviceA group composed of various hydronic units permits better management for the lowest running cost.Coordinating the units for optimized operating times assumes fundamental importance and provides significant advantages in terms of reliability (e.g. the compressors) while also permitting energy savings and delivering water flows constantly at the right temperature without fluctuation.Resources are a lways used according to the user 's requirements without needless compressor cycles or power absorption peaks. The unit pumps are intelligently managed.The number of hours of operation is balanced for more efficient maintenance. Resource priority assignment gives precedence to the unit with greater efficiency: such as chillers with free-cooling function. The stand-by mode grants response to possible peaks in load.The elevated characteristics offered by the serial interface keypad are the highest currently available in the market.
Convenient application and maintenanceFully computer controlling, menu displaying, self-checking of unit, running, load adjusting and safety protection are all completed by computer control system. Daily operation is only to switch on starter. Multiple refrigerating systems are available for standby equipment. The unit is available of functions such as fault protection, memorizing and alarming. All faults are clearly displayed. Each return circuit has inspection valve with "pump down" function which is convenient for repairing.

FWS3000 Field Web ServerDevice for supervising Climaveneta units. Supervision
takes place via a direct link with the computer or via
LAN: hence this option can also be managed through
internet resources thanks to the built-in webserver and
the availability of suitably defined graphical pages.
Thus the resulting supervision does not entail installing
any additional software on the computer and, moreover,
employs the most common types of browser; this means
any networked computer can be used.
