OXA-440N/620N

Mycond OXA-440N and OXA-620N are direct expansion units with horizontal (side) air supply. Mounted on a wall or column, they throw the air up to 24 m along the bay — for buildings where ceiling mounting is impossible.

Mycond OXA-440N side discharge DX unit with horizontal air supply

Why it pays off

Cooling 45 and 61.5 kW, heating 50 and 69 kW.
Horizontal throw up to 15 and up to 24 m.
R410A refrigerant — no boiler room, no water mains.
Air flow 6700 and 10 100 m³/h.
Wall or column mounting — the ceiling stays free.
Flareless pipe connections.

When side discharge is needed

In halls with overhead cranes, ceiling conveyors or continuous racking there is simply nowhere to hang a unit. Side discharge units are installed around the perimeter: the jet runs along the bay and mixes the air through the full depth of the building.

The same approach works in high-bay warehouses with dense racking, where the air has to be pushed along the aisles rather than delivered from above.

Wireless control

Mycond OXA wireless control system with OXA-V terminal and OXA-T2 sensors

What the controller actually adjusts

Throw distance — fan speed and vane position set how far the jet travels, from short range to the full 24 m.
Capacity per zone — the outdoor unit shares refrigerant by actual demand.
Wireless sensors — placed at the far end of the aisle, where the jet has to be still working.
One terminal for the whole fleet — up to 1024 units within a 2 km radius.
Supervision — Modbus RTU into the BMS, alarm log, smartphone access.
Protection — refrigerant pressure and temperature monitoring, phase monitoring, over-voltage and over-current cut-out, soft start.

Dimensional drawing of the Mycond OXA-440N and OXA-620N units

DWG drawings are available on request.

Where it is used

high-bay warehouses with dense racking;
halls with overhead cranes and conveyors;
sports halls and ice rinks;
long, narrow buildings and galleries;
sites where ceiling mounting is not permitted.

We size and lay out OXA systems for industrial and logistics facilities across Europe — send the building geometry and the loads, and you get a layout with the units positioned on the plan.

Frequently asked questions about the Mycond OXA-440N/620N

How far does the jet reach?

Up to 15 m for the OXA-440N and up to 24 m for the OXA-620N with stepless speed control.

Is a boiler room required?

No. This is an R410A refrigerant system: an outdoor unit, two copper lines and a condensate drain.

Can it be mixed with ceiling units?

Yes — side discharge and ceiling units can share one control system on the same site.

How many units are needed?

It depends on the building geometry and the heat loss — we prepare the layout with the units positioned on the plan free of charge.
