When we developed the Indigochiller we aimed to build in features that we believed would make it the best chiller on the market. By “best” we mean the chiller that would offer the lowest cost of ownership to the end-user over the expected life of the plant. We built in unrivalled durability through the use of rugged, industrial components and we aimed to make the chiller leakproof, ensuring that all sources of refrigerant leak were eliminated wherever possible.

Year round efficiency is assured through the combination of the unique Turbocor compressor with Star’s own control software, incorporating energy saving features that are not available on any other chiller. Best of all, we designed the entire chiller to make it as easy as possible to keep the unit operating at the height of design efficiency. Heat exchangers are accessible, so they can be cleaned regularly to maintain peak performance. The control software includes a performance guide which constantly monitors the chiller against current operating conditions and indicates when the COP is drifting away from the design conditions.

Of course anyone can claim that their product is efficient, reliable and maintenance friendly. That’s why we invite you to “go for 3 points”. We match our impressive chiller with an equally impressive three-point guarantee:

Reliability – we include a fully comprehensive “no-quibble” guarantee on all parts for three years from the date of commissioning of the chiller. The guarantee includes the cost of our labour in removing defective parts and repairing or replacing them as required.

Efficiency – we guarantee for three years from the date of commissioning to remedy any deviations from “as-new” performance, as measured against the built-in performance map in the control software. If the software indicates that remedial action is required to bring the chiller back up to the original performance we will provide the necessary labour and materials to achieve this.

Tightness – we promise for the duration of the guarantee to replace any refrigerant lost through leakage from the unit. We will pay for the refrigerant and the labour required to top up.

Star Refrigeration offers bespoke chillers using Turbocor compressors from capacity 250kW to 1000kW.

Key features of the Indigochiller unit include:

  • Onboard PLC with built in performance monitoring/reporting and option for remote access
  • Flooded shell and tube heat exchanger
  • Enhanced tubing for close temperature approach
  • Floating suction pressure control
  • No refrigerant loss
  • Easy to clean
  • Turbocor centrifugal compressors

Refrigerant type

HFCs (Hydrofluorocarbons) are non ozone depleting and the refrigerant of choice in a wide range of new refrigeration and air conditioning equipment.

HFO is a low global warming potential (GWP) refrigerant for use in automotive air-conditioning systems.

Designed and engineered by Star Refrigeration, Indigochiller offers unrivalled long term performance in air conditioning and process cooling. The low charge, high efficiency unit is suitable for medium to large scale applications.

Other benefits consist of:

  • 3 year parts, efficiency and refrigerant warranty available
  • 10 years in field product experience
  • Good access space for maintenance
  • Unique Indigochiller ‘leak tight’ design
  • Realtime monitoring and reporting of chiller performance to ensure optimum efficiency and reliability
  • Low noise operation
  • Choice of HFC or HFO refrigerant
  • Choice of water or air cooled solutions
