5 Star Super Spar

ROCS has been involved with this project for many years. From the first initial store opening many years ago, to the extension of the store and now to the replacement of the existing multiplex system. ROCS has had an ongoing relationship with the customer. The store currently shares a multiplex and water-loop refrigeration system. The current multiplex system is being removed and a new energy-efficient one is taking its place. The store is currently running on R22 refrigerant which is now being phased out due to the effects the gas has on the ozone. Latest low GWP refrigerants has been utilized and all previous lubricant removed from the piping. The store is currently being audited for a case study to show retailers the savings that will be made once the new system is up and running.
