OXA-HK

Mycond OXA-HK holds the entire indoor climate of a hall: heating up to 144 kW, cooling up to 104 kW and 20 kg/h of mist humidification, with air flow up to 10 100 m³/h.

Mycond OXA-HK unit with water coil, humidification nozzles and condensate drain

Why it pays off

Heating 48…144 kW and cooling 22…104 kW.
Humidification 20 kg/h at 5–7 MPa.
Air flow 6900–10 100 m³/h.
Mounting height up to 23 m — the highest in the combined range.
Droplet eliminator and DN25/DN32 condensate drain.
Wireless control with hygrostats in the working zone.

Year-round climate without three separate systems

In winter the unit heats from the boiler circuit and keeps the humidity that would otherwise fall to 15–20%. In summer the same machine runs on chilled water. Instead of three systems there is one casing under the roof, one control system and one service contract.

High-pressure humidification also works in cooling mode, which matters for plants where humidity is specified all year: textiles, printing, tobacco, electronics.

Wireless control

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

What the controller actually adjusts

Humidification output — nozzle groups by hygrostat, constant droplet size at 5–7 MPa.
Guide vane position — a tight jet down in winter, a wider pattern in summer.
Fan speed — frequency control across the whole range.
Wireless sensors — temperature and humidity read at the machines.
Supervision — Modbus RTU into the BMS, alarm log, smartphone access.
Protection — humidification blocked without airflow, phase monitoring, anti-freeze, soft start.

Frequently asked questions about the Mycond OXA-HK

How does it differ from the OXA-K?

Same heating and cooling unit, plus a built-in high-pressure humidification system rated at 20 kg/h.

Is water treatment required?

Yes — distilled or low-mineral water and a high-pressure pump station for the nozzles.

At what height is it installed?

From 4 to 23 m depending on the size; supply angle and speed are matched to the height.

Does it need a drain?

Yes, in cooling mode — a DN25 or DN32 male-threaded condensate connection.
