Factory Acceptance Checks for an Industrial Water Chiller
A buyer's guide to defining pass or fail checks for a factory acceptance test on a water-cooled industrial chiller, using the stated nominal capacities as reference points only.
Before signing off, decide how the factory acceptance test will prove the chiller meets your duty. For a unit stated at 65 kW nominal cooling and 68 kW nominal heating, ask the supplier to define the test conditions behind those figures and to state whether the factory test will reproduce them or only verify basic operation.
Build the pass or fail list around observable checks. Will the test record water flow, inlet and outlet temperatures, and the resulting capacity, or only confirm the compressor and controls run? Ask for the acceptable tolerance on measured capacity against the nominal value and who calculates it. Confirm whether heating mode is tested separately, since the nominal heating capacity differs from cooling. Include leak checks on the water circuit, verification of safety interlocks and alarms, and a controls sequence test. For dimensions, confirm the 2,000 × 1,060 × 1,957 mm figure refers to the supplied configuration and check access for connections and maintenance.
Before requesting a quote, confirm with the supplier which tests are performed at the factory, what instrumentation and records are provided, the acceptance tolerances, and whether a witnessed test is available.
