VKN1
Trench heating fan assisted
Product features:
- new generation of fan assisted trench heaters
- no compromised thermal outputs
- health and safety met – any servicing current only 24V
- highly energy efficient heat exchanger
- product compliant to PN-EN 16430
Basic sizes:
Trench height: 65, 90 mm
Trench width: 140, 170 mm
Trench length (Lk): 950÷2000 mm
Non-standard (NS) length heaters can be made on order.
VKN1 fan assisted trench heater, thanks to its small sizes, would fit any limited ceiling/raised floor space. That feature could be specifically useful if you consider trench heaters for retrofitted or thermo-modernised buildings, specifically to the spaces where installing trench heating because of the space limit where previously not possible.
- The shallowest and the narrowest trench heaters from the entire range
- Highly energy efficient heat exchanger
- Low noise and energy efficient EC Fan Motors
- Adjustment for casing mounts
- Dedicated control system
- Custom/nonstandard trench heater design
We have achieved more thermal output and shorter temperature adjustment times thanks to using more economical fan motors. Trench heating system savings on the running costs up to 20% thanks to small thermal inertia and electronic temperature adjustment can be easily achieved.
VKN 1 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.
