1 40 Years Caring for Environment PCH Heating Condensing Module for Air Handling and Roof Top Units Efficiency as high as 105% Saving Up to 50% on Consumptions Environmentally friendly

2 Efficiency as high as 105%? You can! Apen Group has designed and developed PCH heating modules for installation in air handling and roof-top units. PCH modules leverage on pre-mix and modulation technology to exploit condensation and reach efficiency levels as high as 105% according to lower heating value (LHV - Hi). Efficiency % (Hi) ,0 % PCH Module 89,0 % PCH module is built with environment-friendly, totally recyclable materials, such as steel and aluminium. The heat produced using PCH module's "clean combustion" is earth-friendly and convenient: the burner completely pre-mixes air and gas while the system constantly and logically adapts heat output to changing ambient heating requirements. A microprocessor-based device controls continuous modulation of thermal power output and adjusts it to heat requirements. When modulation of heat output is enabled, an advanced regulating device installed on the main burner monitors and adjusts flow rates of combustion air and gas. Why choosing PCH? CLEAN COMBUSTION Traditional Exchanger PCH condensation modules are equipped with burners that fully premix air and gas. Moreover, a regulating device of heat output is installed. This results in: - No emissions of carbon monoxide (CO = 0). - Very low emission of nitrogen oxides, below 30 parts per million (NOx < 30 ppm). - Low emission of carbon dioxide, due to high combustion efficiency (105%) and to reduction of fuel consumption arising from heat output modulation. SAVINGS UP TO 50% ON FUEL CONSUMPTION! High combustion efficiency, up to 105% (referred to LHV), continuous modulation of heat output, and minimized layering of warm air allow fuel savings ranging from 30% to 50% with comparison to traditional heat exchangers. In addition NO NEED FOR A HEAT PLANT savings on plant building cost (boiler, burner, pumps, safety and regulation devices, masonry work); less space is required (units are smaller and require less clearance); no need for plant certification (our PCH module is already fully certified). NO HYDRAULIC CIRCUIT - NO INTERMEDIATE FLUID: DIRECT HEAT EXCHANGE The heat produced by the heater is directly transferred to ambient air through direct exchange with combustion products. These products flow inside a sealed system, totally separated from the heated environment. No intermediate fluid is required, so the hydraulic circuit is unnecessary and water freezing becomes an out-of-date issue. A few minutes are enough for the environment to warm up thanks to the absence of thermal inertia.

3 Construction Features Every part of our PCH modules has been attentively designed and carefully tested in Apen Group's R&D Centre to develop and obtain a top-quality, highlyreliable product. ELECTRONIC CARD The microprocessor-based electronic card regulates continuous modulation of heat output and controls both the electrical fan for air/gas mixing and the gas valve. FURNACE Furnace and air/flue exchanger are entirely built with mild stainless steel (with low carbon content) which assures maximum reliability and long life cycle. The drop-shaped furnace and the air/flue exchanger, whose tube bundle is custom designed, guarantee performance that place PCH modules among the leading units for heat efficiency, with an outstanding value of 105%. Drop-shaped furnace 3 5 PREMIX BURNER The burner is entirely made of AISI 430 steel and undergoes specific engineering processing that guarantee top reliability and high thermal-mechanical performance. 4 1 Control input (0-10 volts) AIR/GAS MIXING: GUARANTEED SAFETY An advanced technique of air/gas mixing guarantees total safety. The gas valve delivers gas according to the air:gas ratio set at the premises. If combustion air fails, the gas valve shuts up. If combustion air decreases, the valve automatically reduces gas flow while maintaining optimal combustion parameters. Working Principles Modulating electronic card PCH modules are designed to serve as heating units into air handling and roof-top systems. They are built to be installed in standalone air handling units: you only need to connect power and gas supplies. Air is heated by contact with furnace and exchanger tube walls. The furnace (1) is fabricated with AISI 430 steel while tube bundle (2) and flue gas hood (3) are made of AISI steel with low carbon content, so as to resist condensate corrosion. Premix gas burner (4) guarantees carbon monoxidefree emissions and a level of nitrogen oxide below 30 parts per million. The electronic card (5) controls the burner and continuously modulates heat output in between min and max capacity. This modulation is based on the regulation parameters set and on the values detected by the unit regulation system. The electronic card includes a 0-10 VDC input and works as a real 3-way valve for water regulation. SAFETY AND CONTROL DEVICES The following devices are installed on PCH modules: 1. Safety thermostat with manual reset and positive safety 2. Electronic ignition device for the burner and ionisation flame control device 3. Ignition and flame detection electrodes

By assigning to PCH module the approval number 0694BM3433, KIWA GASTEC has certified that this modules comply with the following Directives: - 90/396/EEC - Directory on appliances burning gaseous fuels 90/392/EEC - Machinery Directive - 72/23/EEC - Low Voltage Directive - 89/336/EEC - Directive on Electromagnetic Compatibility

5 Fields of application PCH modules can be modularly assembled in order to reach very high thermal outputs. Actually, modules can be assembled in series or parallel installation, according to project requirements. For instance, four PCH092 modules can reach a maximum power output of 368 kw with a modulation field ranging from 368 kw down to a minimum power of 31.5 kw, according to specific needs. The units can be controlled in three ways: Proportionally, by means of an external 0-10 Vdc By means of an ON-OFF switch Incrementally, when more units are installed. PCH modules can also be installed outdoor without any protection. PCH modules are suitable for installations with C- and B-type layout of flue gas exhaust system.
