OXA-HD — Series with humidification

Series with air humidification (OXA-HD). A ceiling-mounted heating unit with an integral high-pressure water atomising system. The nozzle assembly sits inside the air diffuser itself, so the unit holds the target relative humidity while it heats — with no scale build-up or deposits.

Features

• 🔥 Hot water heating
• 💦 Humidification by high-pressure nozzles (fine mist atomisation)
• 💧 Water quality: distilled or low-mineral water
• 🌀 Vortex distribution and VAV control — no air blowing directly at people
• 📶 OXA-V / V2 terminal, OXA-T2 sensors, Modbus RTU

Notes. A standard unit ships with 4 nozzles, each rated at a maximum of 5 kg/h. Extra nozzles can be fitted to raise output, but no more than 6 per unit — beyond that the area directly below the air outlet becomes too humid.
