Condensing Gas Heating Modules

Apen Heat Exchanger

Apen Group has designed and developed PCH/new heating modules for installation in air handling and roof-top units. PCH module is built with environment-friendly, totally recyclable materials, such as stainless steel and aluminium.

The heat produced using PCH module’s “clean combustion” is earth-friendly and convenient.

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.

Product range is able to satisfy all heating needs

New Gas Modules PCH/new present an extended power range which goes from 5 kW to 400 kW. This result is achieved thanks to the possibility to assemble standard modules in parallel configuration. You can choose between three gas module configurations:

A system:
Single modules with max power between 5 kW to 100 kW.

B system:
Combined modules with horizontal /vertical parallel combination with max power between 13 kW to 400 kW.

C system:
Combined modules with horizontal parallel combination with max power between 13 kW to 200 kW.
