How It Works - Heat King IDF1000 Operation Manual

Building
Construction site
Indirect fired:
This equipment was designed for space heating of buildings under construction, as an outdoor
application with flue gases discharged outdoors. This unit does not require an external power
supply.
A diesel operated engine is managing the fan via a centrifugal clutch. The fan drives ambient
air through a large flue-air heat exchanger, and delivering the warm airstream to the building or
construction site. The design also allows to recirculate the air from the building, while providing
adjustable make up air.
A diesel fired burner provides the heating capacity. Optional, fuel is supplied by an external or
an on-board diesel tank. A Programmable logic controller (PLC) manages the operation of the
unit.
There are two alternatives to control the supply temperature of the unit: local or remote.
Local is a temperature sensor located at the end of the unit and monitors the temperature of
the air leaving the unit. Remote is a thermostat located inside the site being heated, which re-
quires a wire connection onto the unit. When the PLC detects the need for heat, (supply tem-
perature below Set point), it powers up the burner while beginning to drive the engine's rpm
up. As the rpm increases, the centrifugal clutch slowly engages the fan until the unit reaches
the user-set fan speed.
