Air-cooled and water-cooled condensing units for refrigeration and air conditioning
BITZER condensing units are fully assembled refrigeration units designed for heat rejection in refrigeration and air conditioning systems.
They are quick to install, flexible in use, and suitable for a wide range of refrigerating capacities. Available as air-cooled condensing units, water-cooled condensing units, and units without a compressor, they support application-specific system design.
Thanks to matched components, optional accessories, and compatibility with low-GWP refrigerants and natural refrigerants, they enable efficient, reliable, and regulation-compliant operation across commercial refrigeration, process cooling, and air conditioning.
Series without compressors additionally allow customized system configurations.
Air-Cooled Condensing Units
BITZER air-cooled condensing units are compact refrigeration systems that use ambient air for heat rejection, eliminating the need for external cooling water.
They are quick to install, require low maintenance, and are suitable for outdoor installation in many environments.
These units are widely used in:
- Commercial refrigeration (retail, supermarkets)
- Process cooling and cold stores
- Pharmaceutical industry and laboratories
They support a wide range of refrigerants, including low-GWP refrigerants and natural refrigerants, enabling sustainable system design.
Water-Cooled Condensing Units
BITZER water-cooled condensing units use water-based heat exchangers to dissipate heat efficiently, making them ideal for controlled environments or applications with limited air circulation.
They offer high efficiency, especially in low- and medium-temperature applications, and are suitable for both stationary and marine use.
Key advantages include:
- Compact design and high reliability
- Stable performance independent of ambient air temperature
- Flexible use with various refrigerants, including low-GWP options
Typical applications:
- cold stores
- hospitality
- pharmaceutical facilities
- logistics
- storage systems
Condensing Units Without Compressor
Condensing units without compressors are pre-configured condenser modules equipped with EC fans and liquid receivers, but without a built-in compressor.
This design allows the free selection and combination of compressors, enabling maximum flexibility for customized refrigeration systems.
They are particularly suitable for:
- System integrators and OEMs
- Individual plant engineering projects
- Applications with specific performance or refrigerant requirements
