OXA-HD

Mycond OXA-HD is a ceiling heating unit with built-in high-pressure mist humidification. One machine holds both temperature and humidity — exactly what textile, printing and electronics production needs.

Mycond OXA-HD unit with water coil and high pressure humidification nozzles

Why it pays off

Heating 28…103 kW from hot water.
Humidification 20 kg/h at 5–7 MPa nozzle pressure.
Four nozzles as standard, up to six on request.
Air flow 6700–9700 m³/h.
Mounting height up to 17 m, noise below 60 dB.
Controlled by the OXA-V terminal and wireless hygrostats.

Why humidity matters as much as temperature

Heated air in winter dries down to 15–20% relative humidity. Every process engineer knows the consequences: yarn breaks, static build-up, dust, printing defects, timber shrinkage and complaints about dry air.

Airflow and mist distribution from a Mycond OXA-HD unit in a textile hall

The OXA-HD atomises water at 5–7 MPa straight into the warm jet: droplets a few microns across evaporate inside the airstream, so nothing settles on the floor or the machines. The feed water is distilled or low-mineral, which keeps white dust off the equipment.

Wireless control

What the controller actually adjusts

Humidification output — nozzle groups switch on by hygrostat, constant droplet size at 5–7 MPa.
Guide vane position — the supply angle keeps the mist evaporating before it reaches the working zone.
Fan speed — frequency control across the whole range.
Wireless sensors — humidity and temperature read at the machines, not at the unit.
Protection — humidification is blocked without airflow, plus phase monitoring, anti-freeze and soft start.

Feed water	Distilled / low-mineral water
Spray flow, kg/h	20	20
Nozzle pressure, MPa	5–7	5–7
Noise, dB	<60	<60

Standard configuration is four nozzles at 5 kg/h each. More than six nozzles per unit is not recommended — local humidity under the diffuser becomes too high.

Weaving mill: humidity keeps the yarn intact, and the warm jet is driven from under the roof down to the looms.

textile and garment production;
printing houses and packaging plants;
electronics and assembly areas sensitive to static;
woodworking and furniture production;
tobacco and pharmaceutical facilities.

Frequently asked questions about the Mycond OXA-HD

What water does the humidifier need?

Distilled or treated low-mineral water — it prevents white dust on the equipment and keeps the nozzles clear.

Will there be condensate on the floor?

No. Droplets a few microns across evaporate inside the warm jet, and the controller blocks humidification whenever the fan is off.

Can humidification be switched off in summer?

Yes — humidification and heating are controlled separately; in summer the unit simply destratifies the air.

How much moisture does one unit add?

Up to 20 kg/h in the standard four-nozzle configuration; the number of units follows from the hall moisture balance.
