Azanechiller 3.0 is Star’s latest low-charge ammonia chiller
11th February 2025
UK: Star Refrigeration has introduced Azanechiller 3.0, the latest version of its award-winning low-charge ammonia chiller.
Designed, built and tested in the UK, Star insists the latest generation exceeds the EcoDesign regulation’s energy efficiency requirement by up to 110%.
Further, Star claims that it consumes up to 52% less electricity than a standard-rated EcoDesign chiller to deliver the same cooling performance and outperforms UK competitors’ chillers in SEPR by up to 20%.
With its ultra-low ammonia charge of just 0.18kg/kW, the plug-and-play Azanechiller 3.0 range delivers cooling across a range of temperature from -20°C to +25°C.
Capacities range from 140kW to 1,600kW and it is engineered to optimise efficiency across ambient temperatures of up to 40°C.
In addition to improved efficiency, the new chiller boasts advanced safety features, and an extended lifespan of over 25 years.
“With over 120 chillers installed across the UK, Europe, and North America, Azanechiller is the most successful and efficient air cooled, low-charge ammonia refrigeration system on the market today for industrial applications,” said Star Refrigeration’s Azanechiller product specialist, Brooke McKenna.
To maximise performance and minimise energy consumption, Azanechiller 3.0 incorporates IE4 motors, variable-speed reciprocating compressors, high-efficiency EC condenser fans and close-approach heat exchangers.
The standard chiller package offers an industrial solution featuring a galvanised steel base frame, stainless steel for the uninsulated pipework, stainless steel electrical control panel, condenser cleaning hatches and high-performance PIR rigid section insulation to improve longevity and durability.
Safety improvements are also a key focus, with several new design features ensuring a safer working environment. Updates include a portable safety shower, enclosed electrical containment within the base frame, and a rain hood for the control panel. A new optional condenser ladder and handrail, as part of Star’s Safe Access Solution, and hangable fan plates provide safe and easy access for servicing, helping to reduce downtime and lower aftercare costs.
The Azanechiller 3.0 control system also comes ready to connect to Star’s Ethos system, enabling customers to activate Star’s AI-led, data driven performance monitoring and optimisation system to ensure optimum efficiency throughout the plant’s life.
Its advanced data analytics enables Ethos to provides businesses with real-time insights into energy efficiency, system health, and energy usage trends, helping operators to continuously optimise their refrigeration system to cut energy costs year on year.
