What is a Heat Unit?

A Heat Unit is a source of Heat only to a supply of air provided by others. It should not be confused with a complete Heater incorporating its own fan to supply air.

Purpose of Heat Unit

A source of Heat to existing ventilation supply. An alternative form of heating for use with air handling equipment where electric, steam or hot water coils are not practical.

Indirect Fired

The term 'Indirect Fired' indicates that the products of combustion are kept isolated from the main supply airstream. The burner fires a flame into a combustion chamber, the heated products of combustion are directed into a heat exchanger and from there into an external flue which is then discharged into the atmosphere.

Burners and Fuel

Units are available with forced induced draught gas burners, suitable for propane or natural gas; pressure jet oil burners or dual fuel burners capable of fully automatic operation.

Burner type

Gas burners are available for ON/OFF HIGH/LOW or FULLY MODULATING CONTROL.
Oil burners are available for ON/OFF or HIGH/LOW Control.

Unit type

Units are available in a very wide range of heat outputs, designed for high efficiency and built to the latest Regulations and Directives.
All Modules are constructed from a pentapost framework and consist of a Stainless Steel Combustion Chamber, Mild Steel Heat Exchanger with Double Skinned and Insulated front panel to protect the burner and ancillary controls from heat.
All other external panels are of single skin construction.

External Cabinets
