Bock compressor
Bock compressors are semi-hermetic reciprocating models, available in 2- to 8-cylinder versions and covering a wide range of cooling capacities for commercial and industrial applications. Their design includes high-performance valve plates mexxFlow (from HG66 upwards), reliable lubrication regardless of the direction of rotation and advanced electronic motor protection. Compact, robust and modular, they deliver high energy efficiency and easy maintenance.
Bock compressors: performance, reliability and energy efficiency
A benchmark solution for commercial and industrial refrigeration
The Bock compressors are recognised worldwide for their performance, robustness and energy efficiency. Designed for industrial refrigeration, commercial and marine use, they cover a wide range of cooling capacities thanks to an extensive range of compressors semi-hermetic reciprocating with 2 to 8 cylinders.
Used in demanding environments such as cold stores, central air-conditioning systems and food production plants, they provide long-term reliability, even in continuous operation.
Advanced technologies for optimal efficiency
Bock compressors are fitted with valve plates mexxFlow, a patented system that optimises gas flow and reduces internal pressure losses. This innovative system delivers better energy efficiency and greater cooling capacity, while reducing energy consumption.
The highly reliable lubrication, based on an oil pump that works in either direction of rotation, ensures a constant oil supply even in extreme conditions. The large oil sump ensures safe, long-lasting operation.
Simplified maintenance and flexible integration
Designed with maintenance in mind, Bock compressors have a replaceable motor, a suction cover adjustable in 90° steps and a solid metal terminal box with quick fasteners. These features make installation and servicing easier, reducing downtime and maintenance costs.
Safety and multi-refrigerant compatibility
Each compressor is fitted with INT69G electronic protection, which monitors motor winding temperature using PTC sensors. An optional version also monitors discharge gas temperature.
The models are compatible with a wide range of refrigerants, including HFOs, HFCs and natural refrigerants such as CO₂ and propane, meeting new environmental requirements.
