OXA-530N/670N — DX heating and cooling

Refrigerant heating and cooling (OXA-530N/670N). A high-efficiency system designed to work with condensing units or VRF systems in both heat-pump and active cooling modes. The refrigerant is environmentally sound R410A.

Features

• ❄️🔥 Direct expansion (DX): heating and cooling from a condensing unit or VRF
• 🌍 R410A refrigerant, flare-free pipe connections
• 💧 Drain pan and condensate discharge connection
• 🌀 Vortex distribution, blades driven by a Belimo actuator
• 📶 VAV control, OXA-V / V2 terminal, Modbus RTU
