R22 System Replacement for Iconic Biscuit Manufacturer

We replaced the ageing synthetic refrigerant chillers utilised across the site. These serve factory and administration process cooling and air conditioning loads.

Client Objectives:

  • Remove ageing plant, R22 and other synthetic refrigerants from the site
  • Increase overall cooling capacity to meet current and future growth
  • Utilise natural refrigerants to meet all cooling loads
  • Achieve high levels of system efficiency without impacting operational reliability
  • Ensure the safety of site and maintenance staff at all times
  • Deliver 30 year plant life expectancy

Key Points

A new central plant room constructed to meet the full site's cooling requirements
The refrigeration plant and components designed to FM Global requirements
8,000kW of refrigeration across four separate systems connected to a common chilled water and common glycol reticulation system
