Bock
The HGX22e/160-4 S Bock is a robustly designed semi-hermetic piston compressor, ideal for refrigeration purposes with its efficient 4.00 hp motor and extensive displacement capacity of 13.70 m^3. Engineered for versatile refrigerant applications, it accommodates a wide range including R134a, R404A, R407C, R407F, R448A, R449A, R507, and R513A, ensuring adaptability across systems. This unit features a 7/8" suction pipe and a 5/8" discharge pipe to facilitate reliable fluid movement, and commands a cooling capacity of 6.91 kW for R407C and 7.99 kW for R404A refrigerants. The compressor operates on a fixed speed of 1450 rpm, underpinned by an oil pump lubrication mode that contributes to continuous smooth operation. Its sturdy construction is highlighted by a weight of 76 kg; it is built with impressive low and high pressure designs of 19 bar and 28 bar respectively. With an IP 66 protection type and INT69 G motor protection, the unit promises durable and safe functionality. Supplementing the main features are accessories such as capacity control options, a crankcase heater, and a thermal protection thermostat for enhanced performance in medium-high back pressure (MHBP) applications. This advanced compressor, adaptable to varied power supply configurations, is also available in an ATEX-certified version, accommodating the need for durability and compliance in challenging environments.
