Opening paragraph:
A leading food service group's bakery operation at a Perth supermarket had a problem most shoppers never see. The prover retarder at Midland Gate had stopped heating and cooling. Bread proving cycles depend on precise temperature control. When that control goes, production stops. So does the shelf.
What Was Happening
The unit had developed a refrigerant leak on the evaporator. The leak was confirmed through pressure testing and could not be repaired in place. The prover retarder was effectively out of action for its primary function. A short-term arrangement was put in place so baking staff could continue using the unit for proving only, with product transferred to a coolroom overnight. That kept the bakery partially operational while parts were sourced.
How It Was Handled
A full assessment documented the fault, confirmed the pressure drop, and attached the relevant information to support a parts order and upgrade job. Once parts were available, the technician returned, decommissioned the system, replaced the evaporator, and recommissioned the unit. Heating and cooling were fully tested and confirmed operational before the job was closed. The process ran across two visits with clear documentation at each stage.
The Result
The prover retarder was returned to full operation with a replaced evaporator and a verified recommission. The operator received documentation across both visits covering the fault, the interim arrangement, and the final outcome. No ambiguity in the service record.
