The BOC Group

Who are The BOC Group

The BOC Group plc was the official name of the multinational industrial gas and British based company more commonly known as BOC. BOC is now a part of the Linde Group.

Scope of the Job

BOC are an existing client for service, maintenance & installation works. We were contracted to replace an existing R22 refrigeration plant for the cooling of Nitrous Oxide gas at low temperature.

The client had a preference for a system which would operate with a Natural Refrigerant.

Location

Worsley, Manchester

The Challenge

The project required the design, supply and installation of a low temperature Hydrocarbon chiller for the production and cooling down of nitrous oxide gas (better
known as laughing gas) which is predominately used within the National Health Service. The cooling down process condenses the gas in to a liquid for storage and
transportation.

The process requires the gas to pass through a heat exchanger with a cooling medium at -31C. Working within a restricted plant space, we also
successfully provided the interconnecting services of preinsulated ABS pipework system for a secondary refrigerant.

How We Helped

The project required a bespoke installation and therefore called upon our expertise in refrigeration and bespoke solutions.

Equipment Installed

• Frigadon Low Temperature Chiller utilizing Hydrocarbon (HC) refrigerant R1270.
• Secondary refrigerant Hycool (potassium formate).
• Pump module with inverter speed controlled pumps.
