1. INTRODUCTION
The Powrmatic Powrmaster TE range of gas fired forced draught,
closed flue, fanned circulation air heaters cover a heat output
range of 88 kW (300,000 Btu/h) to 806 kW (2,750,000 Btu/h)
and are intended primarily for heating commercial or industrial
premises.
Fuel Types
Gas fired units are certified for use on Natural Gas, Group H -
G20, Group L - G25 and Propane - G31.
Oil fired units are supplied as standard for use with 35sec fuel
and can be supplied for use with 28sec fuel as an option.
In accordance with guidelines from our burner supplier, Riello,
the burners fitted to Powrmatic oil-fired heaters are suitable for
fuels with a bio content of up to 10% only.
For fuels with a bio content of more than 10%, please consult
our Technical Department.
The heaters are for floor mounting, freeblowing applications
only.
TE heaters are also available as /EA variants which are suitable
for siting externally.
TE heaters have a double axial fan assembly fitted upstream of
the combustion chamber / heat exchanger assembly to circulate
the air being heated and the system design is for the fans to run
continuously thereby constantly circulating the air in the building.
Each fan is directly mounted onto the drive motor shaft and the
speed is governed by an inverter. Heaters are fitted as standard
with fully automatic monoblock On/Off forced draught gas
burners and monoblock gas control assemblies. High/Low or
