Danfoss 023Z1012 DAS 167 Drayer – High‑Efficiency Cooling Control Unit

The Danfoss 023Z1012 DAS 167 Drayer is a modular control unit designed for low‑pressure refrigeration and air‑conditioning circuits. Operating between 0.5‑2 bar, it is fully compatible with modern refrigerants such as R‑134a, R‑1234yf and R‑290. An integrated PWM driver keeps motor current below 0.35 A, delivering up to 0.9 COP and achieving 15‑20 % energy savings. The unit is suitable for cold storage, supermarket display cases, hotel room climate control, data‑center cooling and light‑industrial HVAC systems. Its modular design makes it ideal for parallel and cascade configurations, acting as a control point for both primary and secondary loops. Housed in a rugged aluminum case with IP54 protection, it operates from –20 °C to +70 °C, tolerating harsh environments. Installation is straightforward with colour‑coded terminals, and maintenance requirements are minimal. Danfoss backs the product with a long‑term warranty and comprehensive technical support, giving system integrators confidence in their investment.
