Danfoss – RGE‑Z1L4‑7DS (061H3045) – Condenser Fan Speed Controller, 230 V

The Danfoss RGE‑Z1L4‑7DS is a robust, compact fan-speed controller designed for air-cooled condenser systems. It features an integrated pressure sensor and phase-angle control to regulate fan motor speed based on condensing pressure, enabling noise reduction and energy efficiency. A built-in switch allows selection between “cut-off” or “minimum speed” modes. Housed in an IP54 casing with adjustable range from 8 to 28 bar.
