OXA-SK — Horizontal discharge with cooling

Horizontal discharge with cooling (OXA-SK). The universal build for wall or side mounting with a horizontally directed air stream, covering both heating and cooling. A purpose-designed coil, a high-efficiency droplet eliminator and a drain pan with reliable discharge keep moisture out of the space entirely.

Features

• 🔥 Hot water heating · ❄️ chilled water cooling (7/12, 8/14, 10/16 °C)
• ➡️ Throw distance: up to 19 / 28 m in cooling, up to 17 / 26 m in heating
• 💧 Droplet eliminator, drain pan and discharge connection
• 🌬️ EBM-papst fan, stepless VAV control
• 📶 OXA-V / V2 terminal, OXA-T2 sensors, Modbus RTU
