A maintenance plan follows the equipment manual, operating hours, environmental contamination and process criticality. Heat-exchanger, fluid, electrical and control inspections should be supported by performance records rather than a universal service interval.

What operators can monitor

Record water temperatures, alarm history, visible leakage and condenser airflow condition. Compare these against established normal values. Work on the electrical panel and refrigerant circuit requires qualified personnel.

Planned service scope

Check filters, exchanger cleanliness, pumps, sensors, electrical connections and protective functions. Adding refrigerant is not an automatic maintenance step; leakage and operating conditions must first be assessed. Oil procedures depend on the compressor and its manual.

Service reporting

Record the date, operating conditions, measurements, work completed and next actions. Compare performance before and after at equivalent conditions. Maintenance does not guarantee a fixed percentage capacity increase; it identifies deterioration and supports proper operation.

Project inputs and calculation boundaries

For a quotation, specify approximate heat duty, fluid, inlet and outlet temperatures, flow, pressure loss and operating hours. Design ambient conditions, indoor or outdoor location and electrical infrastructure are also selection inputs. Flow and temperature readings must represent the same operating point. Do not transfer a catalogue capacity directly to different temperatures; confirm model performance at the required duty.

Commissioning and operating records

Check circuit cleanliness, filtration, air removal, proven flow and sensor readings. Record reference water temperatures and load conditions during commissioning. These values provide a baseline for maintenance and alarm investigations. Confirm pumps, tanks, connections and control options against the agreed quotation scope.

Frequently asked questions

Is the series capacity range sufficient for final selection?

No. Confirm the actual model at the required fluid temperature, ambient conditions, fluid properties and hydraulic duty.

Is cooling capacity the electrical consumption?

No. Cooling kW and electrical-input kW are different quantities. An energy assessment also needs actual load and operating hours.

What information is needed for a quotation?

Provide the industry or equipment, target temperature, approximate duty, flow, ambient conditions, operating hours and details of the existing system.

These explanations provide general engineering guidance. Examples are not field measurements or performance guarantees for a particular model.
