SpiraChill R32 Scroll Chiller and Heat Pump
SpiraChill™ is Airedale’s scroll compressor chiller and heat pump solution and is part of our more sustainable range of cooling solutions, offering partial and full heat recovery on all models.
Available as cooling only or as a heat pump variant
SEER up to 5.0 (Heat Pump 4.89)
Optimised for R32
Excellent part-load efficiencies
Flexible and scalable
SpiraChill uses the latest in scroll compressor technology, optimised for lower GWP refrigerant R32, to offer excellent efficiency and
versatility across a wide range of applications.
Suitable for both comfort and process applications, SpiraChill operates with an in-built sequencer that allows for up to 7 units to be
grouped together (1 master and 6 slaves) delivering flexibility and scalability to our customers.
With scroll compressors that operate in up to 8 stages, SpiraChill offers excellent part-load efficiencies and highly accurate set-point control.
Optimised for R32, SpiraChill delivers SEERs of up to 5.0 (cooling only) and 4.89 (heat pump), making this a sensible, sustainable option.
- EC Fans – Up to 80% more efficient than AC fan equivalent
- Domestic hot water up to 55°C and low water temperature down to −12°C
- Optional inverter-controlled pump(s). Smart water flow control.
- Various condenser coils solutions (Microchannel, RTPF, epoxy coatings, finned protection grills)
- Versatile: Heat pump or cooling-only
- Electronic expansion valves (EEVs) offering potential EER increase of up to 30%
The inbuilt, pre-programmed controller offers:
- Automatic compressor capacity adjustment to match heat load
- Optimised compressor and fan power to minimise overall power consumption across the whole ambient year
- Constant superheat via EEV control
- Variable supply water temperature control. In comfort applications, the design setpoint increases at lower ambient temperatures to offset additional building heat loss
- Variable flow, pump speed is managed to maintain Delta T and provide energy savings
- In-built sequencer – All SpiraChill models come with an in-built sequencer, allowing for up to 7 SpiraChills to be connected without the need for additional equipment, delivering a scalable and cost effective controls solution
- Compressor rotation for equal run hours
- Plate heat exchangers or shell and tube
- Three acoustic configurations
- Refrigerant leak detection
- Integrated hydronic assembly, system tank, partial or full heat recovery
- Power factor correction
- Compressor soft start
