Bock Kältemaschinen GmbH

Bock Kältemaschinen GmbH is a family owned company, managed by Wolfgang Etter, Heinrich Reuß and Udo Klaußner. The company is manufacturer of compressors and condensing units for stationary and mobile RAC. Bock is recognised worldwide for its high quality products, which are exclusively used in the commercial and industrial sectors.

In the case of stationary applications, examples can be found in all areas of refrigeration, such as supermarkets, warehouses, fruit stores, bakeries, the beverage and chemical industry, etc.

However, due to consistent expansion of the product range during recent years, building a/c has become another important sector of application.


Semi-hermetic compressors
- HG suction gas-cooled
- HA air-cooled
Suction gas-cooled semi-hermetic compressor HG and air-cooled compressor HA. Full capacity range of innovative, modern compressor technology with 2/4/6 and 8-cylinders. Suitable for all current refrigerants, as well as CO2.
For the EX range we are the first European manufacturer to offer compressors certified according to ATEX machine category 2.

Open type compressor
For drive with standard motors via V-belt or direct clutch. Flexible motor arrangement allows for practically all drive-related requirements. Suitable for all current refrigerants, also NH3.

Vehicle compressor
For bus air-conditioning and transport refrigeration. Open special compressors in aluminium design with smallest dimensions. State-of-the-art high-speed machines with innovative design details. Unique product range with 2/4 and 6-cylinders.

Open type motor compressors
This exclusive Bock compressor design has been proven with a long-standing history for reliability. The machine has the compact dimensions of a semi-hermetic compressor and yet offers all advantages of an open compressor. Compressor and drive motor are one unit while shaft seal separates the motor and separate housing and is freely accessible. Advantages are always available where an open compressor offers the best solution and yet a semi-hermetic compressor is desired. The machine is suitable for all standard refrigerants in application including Ammonia (NH3).

Progressive technology in and around the compressor Bock has been the pioneer under this motto in developing technical solutions which set the benchmarks for energy and efficiency, operating safety, and reliability, not only for compressors but for the whole refrigeration plant.
