SpiraChill™ R32 Chiller and Heat Pump

Key Features

• 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%

Intelligent Controls
The inbuilt, pre-programmed controller offers:

• Automatic compressor capacity adjustment to match heat load
• Optimized compressor and fan power to minimize 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
