Liquid heat exchangers

AUTOTERM CHX BLACK Matrix heat exchanger is designed to heat 1-2 rooms by separating the hot air with air pipes.
Allows to add up to 2x 75mm air pipes or can be used without them.

This matrix heat exchanger has 2 internal fans with a radiator. Each fan can be controlled additionally if needed or both together by a fan speed regulator.

With a heating capacity of 2,5 kW and a hot air flow rate of 190 m3/h AUTOTERM CHX is great for campervans, RV's & boats.

AUTOTERM CHX Black goes together with any AUTOTERM Flow series liquid heater.

Equipped with low noise & low power consumption fans, it is a great addition to comfort in your vehicle. 

Control of AUTOTERM CHX:

• AUTOTERM FC9 - fan speed controller
• AUTOTERM CHM36 - thermal fan controller

(both controllers can be used for control of an AUTOTERM CHX Matrix heat exchanger)
