Thermal oxidizers

Thermal or catalytic oxidizers dispense with the emissions of unpleasant odors or volatile organic compounds (VOCs) your production process creates. To tackle your emissions issue with an integrated solution, we supply you with the ultimate thermal incinerators that seamlessly integrate with your processes.

Heat recovery

Heat recovery is the holy grail of all our innovative boiler technologies. APCS, our patented automatic in-line cleaning system, at long last ensures that the heat your production process generates no longer goes to waste and, that you get to cut your energy costs.
