Channel unit heater with fan – efficient space heating

The VKN5 channel unit heater is a solution designed for rooms with large volumes and large windows, where efficient and even heat distribution is crucial. It utilizes a modern, quiet fan and a precise control panel, ensuring thermal comfort while simultaneously saving energy. This is particularly important in low-temperature systems, where it allows for optimization of heating costs.

Construction and operating parameters

The heater's construction is based on a solid steel casing (tub) galvanized and powder-coated in black (RAL 9005). Inside there is a high-efficiency heat exchanger made of aluminum and copper, also powder-coated in black. This exchanger is characterized by effective heat transfer to the air flowing through the channel. A low-power fan provides quiet and efficient air circulation, and its DC EC motor further minimizes energy consumption. The heater has an air vent valve, which facilitates its maintenance and ensures proper operation. The maximum working pressure is 10 bar, which guarantees safety in standard heating installations.

Advantages for the installer and end user

• Quick installation: The adjustable tub height system and included struts and mounting anchors facilitate installation in various conditions.
• Versatility: Availability of different channel heights (75, 90, 140, 180 mm), base widths (250, 300, 350 mm) and channel lengths (800-2750 mm) allows you to adapt the heater to individual project needs. The possibility of making a tub of non-standard length further increases the flexibility of the solution.
• Energy saving: The use of an energy-saving DC EC fan and electronic temperature control translates into lower operating costs. Low thermal inertia allows for quick response to changes in ambient temperature.
• Comfort of use: Quiet fan operation ensures thermal comfort without acoustic disturbances. Even heat distribution eliminates the formation of cold zones in the room.
• Integration with BMS systems: VKN5 heaters can be integrated with building management systems (BMS), enabling remote control and monitoring of device operating parameters.
• Availability of accessories: A wide selection of additional accessories (e.g. decorative grilles, air filters) allows for personalization of the heater's appearance and functionality.

The heating power at parameters 75/65/20°C is 770 / 1881 / 2988 W. Water capacity is 1.36 l, and the maximum working pressure is 10 bar. The heat exchanger is made of aluminum and copper, and the tub is made of steel.

The VKN5 heater is an investment in thermal comfort and energy saving that will meet the expectations of both professional installers and demanding end users.
