Solid fuel air heater DEFRO NP AIR 70 kW
Description
Solid fuel air heater DEFRO NP AIR 70 kW
DEFRO NP AIR 70 is a manually fed air heater for workshops and industrial premises. The axial fan moves air through the steel heat exchanger, while combustion gases are discharged through a chimney. Heat is distributed through air without a water circuit.
Construction and operation
- Steel heat exchanger and powder-coated casing.
- The fan controller uses a temperature sensor and allows fan speed adjustment.
- Recommended fuel: dry hardwood logs with a moisture content of no more than 20%.
- Manual fuel loading and intermittent combustion; the fan and controls require an electrical supply.
