Overview
Allmand mobile indirect fired heater trailers are intended to
provide a self-contained heating solution for remote locations
where external power is not available. An indirect fired heater
separates the combustion chamber from the heated air,
allowing clean breathable heated air to flow to the ducting.
The heater trailer contains two heater units each capable of
producing a maximum of 515,000 BTU/hr.
The heater trailer features a control module that keeps the
burner at optimum efficiency. The control module displays
the proper damper setting for the elevation, barometric pres-
sure and temperature at its location. The operator need only
set the damper at the prescribed setting and start the heater
unit. Tuning of the burner, changing the nozzle and checking
with a Bacharach smoke tester is not necessary.
The heater trailer is powered by either a Caterpillar or Isuzu
1.5 liter diesel engine, driving a 9kW generator. The genera-
tor provides a nominal 115 volt AC power to the heaters. The
heaters may be disconnected from the on-board generator
and plugged into a 60 Hertz, 115 volt 30 amp receptacle.
