VKN5
Trench Heating Fan Assisted
Product features:
- New generation of fan assisted trench heaters
- Thermal outputs that are the highest on the market
- Health and safety 24 V current for fan motor
- Highly efficient coil based heat exchanger
Overall sizes:
Trench height: 75, 90 mm

Non-standard (NS) length heaters can be made on order.
Fan assisted VKN5 VKN5 trench heaters has been designed in principle to compensate a cold downdraught from large glazed facades. Trench heating combines the features of low energy consumption with quiet fan motor operation that, in result will increase energy efficiency and enhancing comfort for the end users. Precise yet easy climate control is provided by in-room accurate and user-friendly control panel.
We have designed a trench heating system that provides even quicker reaction for the changes in the ambient temperature coupled with the increased thermal outputs. 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 central heating water system.
VKN5 fan assisted trench heaters are a perfect match for any low fluid’s temperature systems. 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
