Indirect Gas Heater
An indirect-fired industrial gas heater that uses a heat exchanger to completely separate combustion gases from the supply air. Since combustion exhaust does not mix with heated air, it is optimized for environments requiring clean air such as paint booths, food processing, clean rooms, and pharmaceutical facilities.
Available in 4 models from 100,000 to 1,000,000 Kcal/h, featuring stainless steel heat exchangers for superior corrosion and heat resistance. Compatible with LNG, LPG, and city gas, with modulating control for precise supply temperature management.
Applications
Operating Principle — Indirect Firing Principle
Combustion exhaust is discharged externally — heated air remains clean
