Bock
The HGX66e/2070-4 S Bock compressor is a robust semi-hermetic piston compressor tailored for medium and high back pressure (MHBP) refrigeration applications. Engineered to operate with a power supply of 380/420 V-50 Hz-3 ph or 440/480 V-60 Hz-3 ph Y/YY PW, this compressor boasts a substantial 50.30 hp and a displacement of 180.00 m³/h.

It excels with impressive cooling capacities, offering 94.77 kW for refrigerant R407C and 103.18 kW for R404A, and it's versatile for use with a wide range of refrigerants including R134a, R404A, R407C, R407F, R448A, R449A, R507, and R513A. Its 2 5/8" suction pipe and 1 5/8" discharge pipe facilitate efficient fluid movement.

With a weight of 278 kg, a fixed speed of 1450 rpm, and lubrication from an oil pump using FUCHS Reniso Triton SE 55 oil, it maintains seamless performance. The durability is further enhanced by an IP 66 protection class and an INT69 G motor protection type. Accessories like capacity control, a crankcase heater, oil pressure safety switch, start unloader, and thermal protection thermostat ensure operational safety and flexibility.

The compressor unit comes with noteworthy features like electronic frequency control ranging from 25-70 Hz, ensuring adaptable performance in varying conditions. It's also compatible with ATEX installations for safe use in explosive atmospheres, underscoring its suitability for a broad array of refrigeration needs.
