KM EL mixing chamber is the solution for a facility where it is not possible to install additional ventilation systems. Thanks to the chamber combined with an electric heater, a simple but functional mechanical ventilation system can be created. KM EL mixing chamber allows fresh air to be supplied to the room, which can be heated by means of PTC electric heaters mounted in the heater. Once heated, the airflow is blown into the building, providing comfortable temperature and fresh air.
The installation of the mixing chamber with the water heater is extremely easy thanks to the appropriately made brackets, which allow the two units to be connected seamlessly. In addition, the KM EL mixing chambers, in combination with LEO EL BMS heaters and UVO roof fans, form a simple but effective ventilation system that requires no additional installation components. The mixing chamber's simplicity of design and ease of installation, translates into convenience of use and customer satisfaction.
The mixing chamber also offers a number of additional functions. As part of the FLOWAIR SYSTEM intelligent control, the units know exactly when to operate. Thanks to free-cooling or free-heating functions, the units, instead of generating energy, are able to use the outside temperature to provide adequate air comfort. The T-box controller with touchscreen display, which is the brain of the SYSTEM, also controls all devices from one place.

KM EL mixing chambers are equipped with 3 adjustable air inlets: two for recirculation and one for fresh air. Thanks to the infinitely variable opening of the dampers in the range of 0-100%, it is possible to vary the fresh air supply and heat recovery by means of recirculation.
As standard, the KM EL flat chamber is equipped with an EU3 filter (EU4 optionally available), which cleans the incoming air from solid contaminants such as larger pollen or coarse metallurgical dust etc. The filter can be positioned in two locations, giving the option of filtering only outside air or both outside and recirculated air at the same time. Installation of the filter is possible on two sides of the chamber for greater user comfort.
KM EL S and KM EL L, allows you to choose a unit that meets the needs and requirements of the facility.
KM EL can fully cooperate with roof fans. UVO H is a group of roof fans with horizontal air discharge. They are designed for the ventilation of general and industrial buildings. Mounted on the roof of the building, their purpose is to extract exhaust air from the premises.
Application
KM EL mixing chamber with electric heater are used in medium and large buildings, such as industrial halls, warehouses, sales centre, car showrooms or logistics centres.

Wide range of installation options
The LEO EL BMS electric heater with KM EL mixing chambers is mounted horizontally to the wall only, using the KM mounting console or mounting pins. Important installation instructions:
- The unit should be installed to ensure even air distribution throughout the room.
- It is recommended that fresh air be supplied to the unit via straight ducts. The use of ducts with additional local pressure losses may result in a significant drop in the unit's performance.
- The heaters should be installed so that the supply air streams are not obstructed by other objects or partitions.
- When heaters are mounted on opposite walls, an "overlapping" arrangement should be used.
- The heaters should be mounted in such a way as to ensure free air flow around the unit.
