Technical Features

The innovative shape and the wide surface of the

combustion chamber and the exchanger tubes

guarantee a high performance and durability.

The combustion chamber and the smoke

collectors are completely built in stainless steel

(AISI 441 or AISI 310), while the surfaces in

contact with the fumes (tube bundle) are made

of stainless steel with low carbon content to offer

a high resistance to corrosion . The design of the

tube bundle is protected by a patent.

Safety

The heat exchanger is supplied complete with

safety devices; these must be positioned,

obligatorily, by those who build the appliance that

contains the exchanger.

Exchanger Modules GH / Technical Features

The exchanger module GH,

without fan assembly and

electric panel (available on

request), already equipped

with supporting structure, is

composed by a heat exchanger,

a safety thermostat (limit), a

fan thermostat (fan), and a

aluminum frame.

For high-performance models,

maximum energy efficiency

with flame modulation and

operating in condensation

leads the efficiency more than

102%.

Approval

EC Approval in compliance with

all applicable regulations (see

page 32).

Combustion Circuit

• Stainless steel AISI 441

combustion chamber with

wide exchange surface (with

higher volume compared to

the thermal load). Thanks

to its particular shape,

it assures lower thermal

loads and a uniform heat

distribution.

• Reverse flame combustion

chamber, with three-

pass combustion circuit,

completely welded, to assure

a long operating life.

• High efficiency heat

exchanger made of AISI 441

stainless steel.

The exchanger is formed by

a streamlined tube bundle

with conic section with

an aerodynamic design,

guarantees very little

resistance to air passage,

constant speed of passage

of the fumes and thus high

thermal exchange.

• One front and four rear

inspection panels on the

heat exchanger insulated

with ceramic fiber.

• Insulation panel for the

burner plate made in mineral

fibre.

• Condensate drain.

Frame and Casing

• Supporting frame made in

aluminium.

Burner Choice

The burners, to complement

the GH modules, can be:

• Modulating

• Two-stages (high – low flame)

• ON/OFF

The GH modules can be

installed with burners produced

by main burner manufacturers

on the market.

High efficiency exchanger

modules can ONLY be matched

to GAS burners.

Condensate Drain

When a GH heaters used into a

Air Handling Unit and/or Roof

Top Unit, where high flow rate

and low thermal heat drop is

requested, a condensate drain

system shall be provided in the

exchanger.

All exchangers are provided

with five connectors for the

evacuation of the condensate.

The fittings are placed on the

collectors (rear and front), on the

sides (right and left) and on the

lower wall of the rear of the flue

gas collector.

The condensation is allowed

only in case of coupling with

gas burners, while it must be

absolutely prohibited in case of

use of oil burners.

Condensate Drain

Standard on the back - on request at the front

Exchangers Modules GH / Installation

The GH heat exchanger module can

be assembled into air heating units

either in horizontal position or in

vertical position.

The air can flow in two directions:

• EQUICURRENT FLOW: cold air

flows from warmer part of the

exchanger [combustion chamber]

to colder end.

• COUNTER-CURRENT FLOW: cold

air flows from colder [tube bundle]

to warmer end of the exchanger.

Depending on the application, it may

be more convenient one or the other

installation.

EQUICURRENTCOUNTERCURRENT

15

Exchangers Modules GH / Installation

Assembling one or more modules

When the required heat

output exceeds the single

module's output, or when

you like to divide the

minimum heat output

below the minimum value

of a single heat exchanger,

multiple modules can be

assembled into a single

air handling, roof top or

process heater unit, thus

covering any range of

required output.

Using convenient

precautions, modules

can be assembled either

in series or in parallel

layouts and the air flow

can be equicurrent or

counter-current to heat

flow

The exchangers work with direct-blow gas or oil burners.

APEN GROUP offers a wide range of burners that can be

matched to heater modules.

All exchangers are designed, manufactured and tested to

match the burners produced by main burner manufacturers

on the market.

For information on correct matches, see from page 22 to

page 25.

The diagram below shows dimensions of plate and

nosepiece.

IMPORTANT: Nosepiece length must be greater than "X" min

value. Shorter nosepieces could damage the exchanger and

void the guarantee.

The value of ØT indicates maximum nosepiece diameter for a specific heater. If the installed nosepiece is larger, the exchanger will have to

be changed at an extra cost.

For air handling and roof top units and for general heating

equipments, use the exchangers with a speed range from 1.5

to 4.5 m/s.

Lower speed requires accurate checks to prevent overheating of

delivered air. Higher speed will introduce high pressure drops.

The speed is always calculated as referred to the whole module

section, not to inner flow section (see figure).

The charts in this page show air flow rates referred to speeds

ranging from 0.5 to 5 m/s at intake of the section L x H quoted

in figure.

In the following page pressure losses referred to air flow rates

are listed. Flow rates refer to a flow through the section of

module whose dimensions are shown in picture.

The data on the graphs:

• air flow rate / crossing speed chart

• air flow rate /pressure drop chart

are valid for high efficiency modules GH-K and also for standard

modules GH-N.
