Ship cooling

Reliable systems with powerful refrigeration compressors and seawater-resistant shell-and-tube condensers are a must-have at sea, as ships pass through every climate zone in the world. The freight cannot take damage in the process. With sophisticated compressors from BITZER, the cargo stays constantly cooled and the fish stay fresh throughout the journey.

Compressors

HS95 series

HS series

OS series

ECOLINE

The ECOLINE range is the creative advancement of the proven, robust and powerful semi-hermetic reciprocating compressors from BITZER. It combines high efficiency, smooth running, a wide range of applications, flexibility in refrigerant selection, solid design and high reliability. The ECOLINE range is available across our full range of services. It includes the full range of semi-hermetic reciprocating compressors and replaces its predecessors with the same connection sizes.

2nd generation

With the 2nd generation, BITZER has taken a decisive step forward: There is now a model range for chlorine-free HFC refrigerants and HFCKW. Thanks to their highly efficient and robust designs, the standard compressors meet all the criteria for operation with chlorinated and chlorine-free refrigerants.

2nd generation 2-stage

BITZER is raising the bar in terms of technology and capacity for expanded low temperature applications with the 2nd generation of 2-stage compressors. This series is the result of extensive research on the basis of years of experience in the construction of highly efficient and solid reciprocating compressors. The gas flow control and working valves are specially adapted for low temperature applications.

2nd generation 2-stage Tandem

Tandem compressors are the simplest way of connecting two compressors in parallel. Turning on and shutting off one compressor allows for a particularly effective graduation of output. Particularly for applications with load fluctuations, this allows for cost-effective and energy-efficient operation under full- and part-load with all conventional refrigerants.

Condensing Units

K series in seawater-resistant design with ECOLINE compressors

The efficient ECOLINE compressors and the other components of the water cooled condensing units offer an optimally coordinated overall concept, the result of which is an extensive range of applications and capacities. Additional key characteristics include a robust design, compact dimensions and numerous versions, including a seawater resistant design. The condensing units are also equipped for the future, designed for use with low-GWP refrigerants.

Heat Exchangers and Pressure Vessels

K..B water cooled condensers

A wide range of materials is available, alongside a large selection of pressure vessel approvals. A desuperheater version is available.

CXPM water cooled condensers

When both reliability and high efficiency have to be ensured, CXPM condensers are the right choice for the capacity range up to 150 kW. In the standard or the high-pressure version, 15 models always enable operation within seawater velocity safety limits. A wide range of materials is available, alongside a large selection of pressure vessel approvals.

McDEW water cooled condensers

McDEW is the seawater-resistant-design condenser family for medium–high capacity applications (up to 1,680 kW). Low-fouling tubes, reduced seawater velocities and sacrificial anodes help to keep the traditional risks of seawater application under control. A wide range of materials is available, alongside a large selection of pressure vessel approvals.

DM evaporators

DM is a single-pass dry-expansion evaporator for commercial refrigeration and medium-temperature process-cooling applications with a wide rage of evaporation temperatures (from positive-temperature evaporation down to –40°C). DM is optimised for R134a and R407F refrigerants at medium pressures (21.5 bar) and is suitable for HFO and HC refrigerants. The capacity range is 100 to 800 kW. A wide range of materials is available, alongside a large selection of pressure vessel approvals.

Primary oil separators

These oil separators are suitable for use in refrigerant circuits with all HFC refrigerants and R22
