Description

Solid fuel air heater DEFRO NP AIR 35 kW

DEFRO NP AIR 35 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.
