Fan assisted VKN5 trench heaters has been designed in principle to compensate a cold downdraught from large glazed facades. Utilising the features of low energy consumption and operating with quiet fan motor will increase energy efficiency and prevent being disturbing for the end users Precise yet easy climate control is provided by in-room accurate and user-friendly control panel.

We have designed a heating emitter that provides even quicker adjustment reaction coupled with extended thermal output. Savings on the running costs up to 20% thanks to small thermal inertia and electronic temperature adjustment can be easily achieved, when using trench heaters in the system.

VKN5 fan assisted trench heaters are a perfect match for any low fluid’s temperature systems, especially in higher humidity mild environment. The fact the trench heaters distribute the warm air evenly across the room could be considered as their benefit.

  • Highly energy efficient coil based heat exchanger
  • Low noise and energy efficient EC Fan Motors
  • Adjustment for casing mounts
  • Dedicated control system
  • Custom/nonstandard trench heater design
