OXeN heating and ventilation unit with heat recovery is an innovative device on the market that allows fresh air to enter a room and recover the heat energy already generated. Due to its functionality and design, the OXeN unit has received many design awards.
OXeN is the only such device available on the market that provides mechanical supply and exhaust ventilation without the need for ductwork. OXeN is an easy-to-install, energy-efficient ductless ventilation system. It can significantly reduce investment costs and its high heat recovery efficiency reduces operating costs.
The application of OXeN units on the site ensures adequate circulation and a positive effect on the quality of the indoor air, while saving money through heat recovery. In addition, using the intelligent FLOWAIR SYSTEM control, the device knows exactly when to work. The T-box controller with touchscreen display, which is the brain of the SYSTEM, also controls all devices from one place.
Basic parameters

Provides low investment and operating costs, is easy to maintain, perfect for existing buildings.
Each unit is equipped with a complete automation system for intuitive and reliable operation of the unit.
OXeN heat recovery unit is a unit that is immediately ready for operation. No additional mounting consoles are required, as it comes with mounting brackets as standard.
The device is made of extremely durable yet lightweight material. Expanded polypropylene (EPP) provides good thermal insulation and high noise dampening capacity.
Application
OXeN unit is designed for indoor operation providing energy-efficient ventilation to medium and large volume buildings such as petrol stations, shops, workshops, warehouses or sports halls.
Device advantages
X2-FLOW - high heat recovery efficiency was achieved by using two cross-flow heat exchangers. The exchangers are made of aluminium, so they provide high corrosion resistance.
MULTI-FAN TECHNOLOGY - the unit uses two diagonal fan sections, each consisting of 3 units. This allows for even distribution of the supply air flow over the entire surface of the exchanger, efficient heat exchange, quiet operation and energy efficiency.
EPP CASING - the unit's housing is made from
an extremely strong yet lightweight material. Expanded polypropylene (EPP) provides good thermal insulation, high noise dampening capacity and has significantly reduced the overall weight of the unit.
