Due to thermostatic controls, the unit can be left to run unattended for long periods of time, for a fully automatic heating system, or even a frost protection system.
The Kroll warm air heater is of a compact construction. There are no parts protruding from the casing, the flue gas connection is countersunk. The air inlet and air outlet fittings can be stored internally for transport. The unit has got fork lift openings on all sides and lifting eyes are fitted as standard, and the models within the range are designed so they can be stacked when not in use. Another benefit for rental companies, is that the units fits crossways on a standard lorry as it is easily and safely stackable.
All components of the unit, such as burner, fan, control box etc. are enclosed within the robust housing, meaning the heating unit is therefore protected against abuse or misuse by any unauthorized persons.

Thermostat temperature remote control
Set the desired room temperature via the optional remote thermostat. The warm air space heater heats up. When the internal temperature of the appliance reaches +40 °C (factory setting), the fan is set into operation and blows warm air out. When the desired room temperature is attained, the burner turns off. When the ambient temperature drops below this level, the burner is immediately turned back on.
