OXA-DK — Series with dehumidification

Series with air dehumidification (OXA-DK). A ceiling climate unit built to pull humidity down in spaces with heavy moisture loads — swimming pools, wet production areas and storage. It uses a high-efficiency cooling coil to condense moisture out of the air, a pan to collect and drain the condensate, and an optional heating stage to keep the space at a comfortable temperature.

Features

• 💧 Active dehumidification through the unit’s own coil
• 🔥 Heating to hold the room temperature setpoint
• 🛡️ Protects materials and the building fabric from condensation and damp
• 🌀 Vortex distribution, stepless VAV control
• 📶 OXA-V / V2 terminal, OXA-T2 sensors, Modbus RTU
