Reciprocating Compressors
Semi-hermetic
Universal and environmentally friendly: ECOLINE reciprocating compressors offer high cooling capacity with minimal energy requirements and are optimised for HFC, HFO and low-GWP refrigerants. The optional VARISTEP mechanical capacity control offers high part-load efficiency in medium and low temperature application.

Open
Open drive reciprocating compressors are available in two model series: for (H)CFC/HFC refrigerants and ammonia. Due to the open drive design, standard motors can be attached to the compressor via coupling housing or belt drive. Reliability and easy maintenance have made them popular options for years.
Open 2-stage
The open drive, 2-stage reciprocating compressors are optimised for the low temperature refrigeration range. With the optional liquid subcooler, they significantly increase the cooling capacity and efficiency of the entire system. Standard motors can be attached to the compressor via coupling housing or belt drive.
Screw Compressors
Semi-hermetic
Efficient, robust, durable: thanks to the HSK/N version, HS semi-hermetic screw compressors are suitable for many application ranges and refrigerants. The internal capacity control is multistep and, from HS.85, stepless as an optional feature. All HS compressors are suitable for speed-controlled operation. From HS.95 with IQ MODULE.
Open
The OS series separates the flanged motor and refrigerant circuit. Thanks to the OSK/N version, these compressors are suitable for many application ranges and refrigerants, with a separate series for operation with ammonia. The internal capacity control is multistep and, from OS.85, stepless as an optional feature. All OS compressors are suitable for speed-controlled operation. From OS.95 with IQ MODULE.
Hermetic
Hermetic scroll compressors are used particularly in air conditioning and heat pump applications. They offer high cooling capacity, reliability, exceptional energy efficiency and low noise levels.
ORBIT+
The new ORBIT+ scroll compressor series features a line start permanent magnet (LSPM) motor for highest efficiency requirements and enables customers to fulfill the highest energy efficiency standards in air conditioning applications like chillers and heat pumps well
ORBIT FIT
The ORBIT FIT series is the new ORBIT series with Flexible Injection Technology for economiser operation for improved efficiency, increased capacity and enlarged application envelopes.
ORBIT TANDEM/TRIO
All ORBIT series can be combined flexibly in numerous tandem and trio configurations with the use of the BITZER Advanced Header Technology (BAHT). Next to the reliable oil management, the technology also enables capacity modulation by on-off operation of several compressors.
Heat Exchangers and Pressure Vessels
Water-cooled condensers
Five series of water cooled condensers with a standard capacity of up to 1,680 kW satisfy all condensation needs with versions for normal/technical water and for seawater. HFC, HFO, HFC/HFO blends, propane and NH3 can be used as refrigerants. A complete selection of pressure vessel approvals and certifications for stationary and marine applications is available.
Shell and Tube Evaporators
Dry-expansion evaporators designed with ‘U-tube’ or with a single-pass design, combined with patented refrigerant distribution systems, offer the best performance and the lowest approach between evaporation temperature and water-leaving temperature for positive, medium and low (down to –40°C) applications. A selection of materials and a wide approval choice is available. Flooded evaporators offer the highest efficiency available in the industry.
Oil Coolers
BITZER offers five condenser series that can be used in HFC and HFO systems. Notably low approach performances can be reached with standard capacities of up to 1680 kW. Water cooled and air cooled oil coolers ensure additional cooling, with low pressure drop values and reduced energy consumption
