AMMONIA COMPRESSOR PACKS
AMMONIA COMPRESSOR PACKS
Whether for medium or low temperature applications, air conditioning or booster applications, BITZER Ammonia Compressor Packs (ACPs) are just as flexible as the requirements in industrial refrigeration are different. They are available with a wide variety of options and accessories. Always on board: the natural refrigerant ammonia (NH₃, R717).
Refrigerants
- Ammonia (NH₃, R717)
Capacity range
- Two series:
- ACP.85: compressor packs with two or three OS.A85 screw compressors
- ACP.95: compressor packs with one, two or three OS.A95 screw compressors
Applications
- High temperature/AC
- Medium temperature
- Low temperature
- Booster
Industry sectors
- Dairy and process
- Food and beverage
- Cold storage
- Deep freezing
- Leisure
- And many more
Comprehensive standard equipment
- Up to three BITZER OS.A 85 or OS.A95 open screw compressors
- High efficiency motors
- All pipework mounted and tested
- All control wires pre-wired and tested
- Fully assembled
OS.A screw compressors
- VSD operation 25 .. 70 Hz at 1450 .. 4200 rpm
- Slider regulation stepped 50/75/100% (OS.A85) or stepless 25 .. 100% (OS.A95)
- Compressor oil filter integrated (OS.A85) or external (OS.A95)
- Self-aligning coupling housing and direct-drive coupling
- Automatic Vi adjustment (OS.A95 only)
IQ MODULE CM-SW
- Monitors temperatures and pressures and protects compressors
- Integrates the complete electronic compressor periphery
- Controls compressor capacity
OAHC OIL SEPARATOR
- BITZER PED horizontal coalescence oil separator
- State-of-the-art 3-stage oil separation:
- 1st stage: centrifugal and gravity separation
- 2nd stage: demister separation
- 3rd stage: coalescence separation
- Oil carry over rate 2 .. 7 ppm when using PAO oil
- Three models: OAHC 650, 800, 1000
OIL COOLER
- Shell and plate or shell and tube oil cooler
- Design and efficiency optimised for ACP operation
- Same design for both thermosiphon and brine cooling agents
- Multi-pass fully welded design
Efficient
- Parallel connection of several BITZER screw compressors
- Intelligent capacity control
- High efficiency in all operating conditions
Future-proof
- Ammonia (NH3, R717) is characterised by outstanding thermodynamic properties and low environmental impact (GWP and ODP = 0)
Reliable
- System safety thanks to up to three built-in compressors, sensors and other essential components within a single system
Customisable design
- 112 different ACP models
- Tailoring to the individual application possible
Low life-cycle costs
- Technical design ensuring minimum downtime and maintenance costs.
Easy start-up and maintenance
- BITZER ACPs come fully assembled
- Ready for operation in no time
- Accessibility of all components

- High efficiency profile twin screws using advanced geometry and high rigidity
- Automatic start unloading
- Wide speed range with optional VFD: 1500 .. 4200 rpm
- Economiser operation (optional)
- High quality shaft seal
- Internal pressure relief valve
- Compressor-integrated discharge check valve
- Extensive intelligent functions thanks to the IQ MODULE CM-SW link
OS.A95
- One, two or three compressors in one ACP
- Stepless slider regulation (25 ..100%)
- External compressor oil filter
- Integrated double slider for mechanical capacity control
- Automatic Vi adjustment
OS.A85
- Two or three compressors in one ACP
- Stepped slider regulation (50/75/100%)
- Internal compressor oil filter
- Fixed Vi
ACP controller
- Regulates and protects the ACP by using permanent active application envelope surveillance
- Compressor capacity control functions
- Compressor and motor protection
- VFD control and communication via Modbus
- Digital input and output available for system communication
- Highly serviceable
-
