G Series Gas or Diesel Hot Air Generators

G Series Industrial Hot Air Generators

ALWO G Series hot air generators are available with a natural-gas or diesel burner and are designed for direct space heating or warm make-up air in industrial buildings.

The units can connect to a ductwork system and operate as part of a centralised or stand-alone heating installation. They can also supply an air-distribution plenum for uniform delivery of warm air into the room.

Operating range

  • nominal airflow rates from 4,000 to 23,500 m³/h;
  • nominal heat outputs from 59.3 to 436 kW;
  • configuration with a RIELLO natural-gas burner or a diesel burner;
  • connection to a stainless-steel flue;
  • integration with ducted or plenum-based heating systems.

Safety and engineering: the burner type, fuel train, flue-gas discharge, combustion-air supply, controls and safety devices are specified for each project and must be selected and installed according to the manufacturer’s requirements and the regulations applicable to the installation.
