Cooling capacities from 140kW to 1600 kW for fluid temperatures from -20°C to +25°C

Azanechiller 3.0 exceeds Eco-Design regulations energy efficiency requirements and delivers immediate reductions on energy costs after installation.

Key features of the Azanechiller include:

  • Variable speed reciprocating compressors
  • High efficiency IE3 drive motors
  • Low profile, air cooled condenser with high efficiency
  • EC condenser fans and epoxy coated fins as standard
  • Compact plate and shell evaporator with integrated separator
  • PLC control to continuously optimise chiller operation
  • Remote PLC access facility
  • Continuous performance monitoring and optimisation
  • Factory charged, run tested and commissioned prior to dispatch
  • Options for:
    • Single or twin compressor
    • Axitop for all condensers
    • Heat recovery
    • Witnessed performance test at factory

Refrigerant type

Ammonia is produced by biological processes, is naturally decomposed, and does not add to the global greenhouse effect.

The Azanechiller is ideally suited for cooling applications including:

  • A future proof chiller solution which does not fall under the F-Gas regulation
  • A chiller that has an efficiency 71% higher than the Eco Design Requirement
  • An SEER of 5.60 for comfort cooling applications and an SEPR of 7.59 for process cooling
  • Refrigerant charges of 0.18kg/kW
  • 39% reduction in chiller weight
  • 15% reduction in footprint
  • No plant room required
  • 20+ year life expectancy
  • A quick installation
  • A chiller that is ready to run when delivered to site

Azanechiller 3.0

Star Refrigeration have re-engineered the Azanechiller range to help our customers reduce energy costs, avoid the uncertainty of synthetic F-Gas refrigerants, and invest in a future proof solution that will deliver reliable cooling for 20+ years.

With COPs up to 3.63 at 100% load and 35°C ambient, increasing to 11.9 at 50% load and typical UK ambient temperatures of 10°C, the new Azanechiller 3.0 is 15% more efficient than its screw compressor counterparts at design conditions.

Each Azanechiller package is manufactured, charged, commissioned and run tested at Star Refrigeration’s production facility in Glasgow.

A low charge design uses a combined evaporator/separator to achieve refrigerant volumes as little as 0.18kg/kW. As ammonia has zero global warming potential, the chiller does not fall under the European F-Gas regulation, unlike alternative technology using HFC refrigerants such as R134a and R410a.

Designed and manufactured in the UK

The high and medium temperature Azanechilller ranges have cooling capacities from 140kW to 1,200kW for secondary fluid supply temperatures from -10°C to +10°C.

  • HVAC
  • Temperature Controlled Storage
  • Food Production
  • Ice and Leisure
  • Process cooling (pharmaceutical, chemical, petrochemical)
  • Data Centres
Over 100 Azanechillers have now been installed with a combined capacity of approximately 70 MW and over 4 million hours of continuous operation.
In terms of savings for our customers, the Azanechiller 2.0 has delivered the equivalent of approx. £65 million saved on running costs and 100,000 Tonnes of CO2 versus the baseline Eco Design MEPS standard (European and UK Regulations).

Case Studies

Example 1: The National Curling Academy at The Peak

The EcoDesign compliant National Curling Academy’s Azanechiller breaks energy efficiency standards with a Seasonal Energy Performance Ratio (SEPR) of 4.28, which is 66% higher than the Minimum Energy Performance Standards set by the Eco-Design Directive. The Azanechiller offers a coefficient of performance (COP) which is 62% higher than competing HFC screw chillers and 42% higher than alternative low carbon refrigerants. In terms of the impact on carbon emissions and life cycle costs, this resulted in a 700 tonne and £241,000 saving respectively after 20 years

Example 2: Gist Chill Store (58,500m3)

Gist’s Azanechillers exceed the ‘Minimum Energy Efficiency Requirements’ set by Europe’s Ecodesign Directive by 56%.

The plant has now been fully operational for a year and readings from the site indicate that the energy usage is around 5kWh/m3 per yr. This is equal to one eighth of that of good practice guidelines and one twelfth of typical cooling demands for similar stores across Europe, bringing the 60,000m3 facility’s annual energy bill to just over £29,000 and its CO2 emissions to under 83 tonnes/year.

Gist Chesterfield is now set to remove 943 tons of CO2 per year when compared to the typical cooling demand of similar European chillstores.

Example 3: First Milk

First Milk replaces cheese chill plant with an Azanechiller which improved operating efficiency by 25% and cheese output by just under 39%. The low charge ammonia chiller has a charge of just 42kg of ammonia. It also exceeds the ‘Minimum Energy Efficiency Requirements’ set by the Ecodesign for Energy-Related Products Regulations- the UK instrument that enacts the European Ecodesign Directive, by an impressive 75.2%. This means that the new installation will have a dramatic impact on cutting First Milk’s carbon emissions and will provide massive energy savings for the business.

Example 4: East Kilbride Ice Rink

East Kilbride ice rink’s state of the art Azanechiller has a Seasonal Energy Performance Ratio (SEPR) of 4.32, which is 71% higher than the EU EcoDesign Directive requirement.

Figures show life cycle cost savings of £278,000 and carbon savings of 1,204 tons of CO2 over 20 years.
