OXA-HK — Cooling / heating / humidification

Universal cooling / heating / humidification series (OXA-HK). A multifunction ceiling unit for full year-round climate control: a dual-duty water coil for heating and cooling, a condensate collection and drainage system, and a high-pressure atomising nozzle assembly that holds humidity precisely where you want it.

Features

• 🔥 Hot water heating · ❄️ chilled water cooling
• 💦 Humidification by high-pressure nozzles at 5~7 MPa
• 💧 Condensate collection and drainage system
• 🌀 Vortex distribution, stepless VAV control
• 📶 OXA-V / V2 terminal, OXA-T2 sensors, Modbus RTU

Heating and cooling output matches the OXA-K series, since it uses the same dual-duty coil. Full tables are in the PDF catalogue.

Non-standard versions (explosion-proof, anti-corrosion, air purification, increased cooling capacity) are available on request.
