OXA-ED

Mycond OXA-ED is a recirculating ceiling unit with electric PTC heaters. It is the option for buildings that have neither gas nor a water circuit — all it needs is a 380 V supply.

Why it pays off

No boiler room, no gas, no pipework.
Heater banks 30–45 kW (size I) and 35–65 kW (size II).
Heat output 25.5–55.25 kW.
Air flow 6700–9700 m³/h.
PTC elements are self-limiting in temperature.
Mounting height up to 17 m, noise below 60 dB.

When electric heating is the shortest route

Not every building has district heating or a gas connection. A leased hall, a service bay or a section inside a warehouse often has only power — and that is where the OXA-ED delivers heating with no capital works: hang the unit, connect the cable, and the space is warm within hours.

The PTC elements reduce their own output as they get hotter, and the interlock with the fan prevents the heaters from running without airflow — safe both for the equipment and for the building.

Compared with portable and wall heaters

Thermal comparison: local heaters warm the roof space, Mycond OXA heats the working zone

Portable fan heaters and wall units warm a small radius and send the rest of the heat under the roof. The OXA-ED distributes the heated air across the whole floor area — for the same electricity consumed, the working zone is warmer and less is lost through the roof.

Wireless control

What the controller actually adjusts

Heater output — PTC banks switch in stages against the setpoint, without overshoot or current surges.
Guide vane position — supply angle from a tight jet to a wide fan pattern.
Fan speed — frequency control across the whole range.
Wireless sensors — temperature read in the working zone.
Weekly schedules — heating shifted to the cheaper tariff and unit starts staggered in time.
Protection — heaters interlocked with airflow, thermal cut-out, phase monitoring, over-voltage and over-current protection.

Where it is used

Rail depot: the heat is delivered down to the service platforms where people work, not to the roof trusses.

leased halls and warehouses without a boiler plant;
depots, repair bays and service stations;
areas that only need heat for part of the shift;
sites with their own electricity generation;
temporary and seasonal production.

Frequently asked questions about the Mycond OXA-ED

Is electric heating economical?

Where there is no gas or district heating it is the fastest solution with no capital works. Schedules and zone control cut the consumption significantly.

What electrical capacity is required?

It depends on the heater bank: 30–45 kW for the OXA-ED-I and 35–65 kW for the OXA-ED-II, plus the fan.

Are the heaters safe?

Yes — the PTC elements limit their own temperature and the interlock stops them running without airflow.

Can it be combined with water units?

Yes — water, gas and electric OXA units can run in one control system.
