TRENCH HEATERS FCH FCH are among the most powerful trench heaters designed for heating and cooling. Both heated and cooled air is raised right up the ceiling to result in an even distribution throughout the room. 4 and 2 pipe connection versions are available. The 4 pipe connection guarantees maximum flexibility, whereas the 2 pipe connection will ensure the maximum capacity. The air flow passing through the appliance is continuously filtered to trap a considerable part of the dust and dirt in the room and protect the heater from contamination. Include drain pans that allow the device to operate...

Especially quiet operation We have achieved exceptionally low noise levels using extremely quiet EC fans and by the optimisation of their rotational speed and design of the devices. Tested according to EN16430 The outputs of all products manufactured by Konveka have been tested by independent accredited laboratories according to the latest standards. With us, 1 kW means 1 kW. All body parts are made of stainless steel Stainless steel provides 100% corrosion protection for an indefinite time. It is also 54% stronger and 45% harder than carbon steel, so it can withstand loads during transportation,...
