AQUAFORCE® 30XW-PZE
AQUAFORCE®
30XW-PZE
Water-Cooled Screw Liquid Chiller/Heat Pump
With HFO-1234ze refrigerant
Cooling capacity: 269~1,100 kW
Heating capacity: 319~1,269 kW
- HFO-1234ze refrigerant with nearly-zero GWP
- Available for cooling (30XW-PZE) or heating (30XWHPZE) operation
- Wide operating envelope: down to -3°C chilled liquid temperature, up to +70°C hot water temperature
- Compact design
- less than 1.2 m width up to 1300 kW
Features
- The 30XW-PZE liquid chillers are the premium solution for industrial and commercial applications where installers, consultants and building owners require optimal performances and maximum quality.
- The 30XW-PZE liquid chillers are designed to meet current and future requirements in terms of energy efficiency, flexibility of use and compactness. They use the most reliable technologies available today:
- Twin-rotor screw compressors with a variable capacity valve
- R-1234ze refrigerant
- Touch Pilot control system
- Flooded heat exchangers that are mechanically cleanable
- The AquaForce PUREtec range is splitted into two versions:
- 30XWHPZE for heating applications
- 30XW-PZE for air conditioning and refrigeration applications
- As standard, the unit can provide an evaporator leaving temperature down to 3,3°C, and when operating as a heat pump, it can deliver up to 55°C (70°C optional) on the condenser side.
- R-1234ze long-term refrigerant solution
- HFO refrigerant with nearly zero global warming potential (GWP < 1) and zero ozone depletion potential (ODP = 0).
- The 30XW units offer increased global performance as well as Carrier’s acclaimed product quality and reliability.
- Major components are selected and tested with R-1234ze refrigerant to minimize failures possibility, as well as many design choices have been taken in this perspective.
- Screw compressors
- Industrial-type screw compressors with oversized bearings and motor cooled by suction gas.
- All compressor components are easily accessible on site minimising down-time.
- Refrigerant circuit
- Two independent refrigerant circuits (from 1000 kW upwards); the second one automatically takes over, if the first one develops a fault, maintaining partial cooling under all circumstances.
- Evaporator
- Electronic paddle-free flow switch. Auto-setting according to cooler size and fluid type.
- Auto-adaptive control
- Control algorithm prevents excessive compressor cycling (Carrier patent)
- Automatic compressor unloading in case of abnormally high condensing pressure.
- Exceptional endurance tests
- Partnerships with specialised laboratories and use of limit simulation tools (finite element calculation) for the design of critical components.
- Transport simulation test in the laboratory on a vibrating table and then on an endurance circuit (based on a military standard).
- Safe design
- Specific poloyester oil qualified by Carrier for using with HFO-1234ze to guarantee and maintain reliable bearing lubrication.
- Specific compressor gaskets compatible with HFO-1234ze, tested and validated by Carrier.
- New relief valves designed for operation with HFO-1234ze
- Specific electrical box with increased tightness and integrated blower that maintains positive air pressure to avoid any risk of ignition.
- New control algorithms
- Specific documentation that contains all the installation, operation, maintenance and safety instructions
Options
- Light-brine solution, down to -3°C
- Master/slave operation
- Terminal and disconnect options
- Pump control/power circuit options
- Waterbox pass, pressure and connection options
- HLI Communications
- Condensing temperature control
- Energy management module
- Low noise
- Thermal insulation
