Channel heater type VKN5-09/25/275 (L) left

Channel heater with fan – efficient space heating

The VKN5 channel heater is an ideal solution for rooms with large volumes and glazing, where even heat distribution is crucial. It utilizes a modern, quiet fan and a precise control panel, ensuring thermal comfort while simultaneously saving energy. The device works perfectly in low-temperature systems, offering a fast response time to temperature changes thanks to its low thermal inertia.

Design and application

The VKN5 heater consists of a durable steel tub (galvanized and painted black – RAL 9005) and a high-efficiency heat exchanger made of aluminum and copper. The heat exchanger is powder-coated black, and includes an air vent valve as standard. A low-power fan (24V DC EC) ensures quiet and efficient air circulation. Thanks to the adjustable tub height, installation is simple and flexible. The heater is suitable for both domestic and commercial installations – offices, shops or conference rooms.

Advantages and benefits

• High heating efficiency: thanks to the use of a high-efficiency heat exchanger and fan, the heater provides quick and effective room heating. The stated thermal power for parameters 75/65/20°C is 1941/4170/5847 W (modes: min/med/max).
• Quiet operation: the modern EC fan ensures almost silent operation of the device, which is particularly important in residential and office spaces.
• Energy saving: electronic temperature control and low fan power consumption allow you to reduce heating costs by even more than 20%.
• Even heat distribution: the channel design ensures even airflow throughout the room, eliminating the formation of cold zones.
• Flexible installation: the adjustable tub height makes installation easier in various conditions. Accessories for raised floor mounting are also available.
• Strength and durability: the galvanized steel tub provides corrosion resistance, and high-quality materials guarantee a long service life. The maximum working pressure is 10 bar.
• Integration with BMS systems: a dedicated control system allows integration with building management systems (BMS), enabling remote monitoring and control of the heater.

The VKN5-09/25/275 (L) heater has a length of 2750 mm, a depth of 90 mm and a grate frame width of 270 mm. The water capacity of the device is 0.79 liters. It is possible to order a heater with a non-standard length (NS).
