Refcomp SP4HF1500 SP4HF150E 15HP Chiller Reciprocating Compressor for Air

The SP4HF1500(SP4HF150E) chiller semi-hermetic reciprocating compressor is a high-capacity 4-cylinder semi-hermetic unit engineered for commercial HVAC liquid chillers, industrial process cooling, and medium-to-high temperature refrigeration systems.

• Commercial HVAC Chillers - Suitable for central air conditioning chillers, water-cooled package units, and air-cooled liquid chillers operating in commercial buildings.
• Industrial Process Cooling - Ideal for manufacturing, plastic molding, and chemical processing facilities where a heavy-duty chiller reciprocating compressor ensures continuous fluid temperature control.
• Cold Storage & Distribution Centers - Designed for medium-temperature cold rooms, agricultural pre-cooling, and logistics temperature-controlled storage.
• Parallel Compressor Racks - Applicable to multi-compressor parallel rack configurations feeding supermarket refrigeration systems and food process chillers.

• What key factors should be verified when selecting the SP4HF1500 for a liquid chiller project?
  You should verify the required cooling capacity, operating evaporating and condensing temperatures, refrigerant choice, and motor electrical specs against the unit's displacement. Providing detailed working conditions ensures accurate model matching.
• What precautions should be taken when retrofitting this unit into an existing chiller unit?
  Confirm line connection diameters, ensure oil compatibility with the existing refrigerant (such as R134a, R407C, or R404A), and inspect the electrical starter panel to verify starting current capacity.
• How often should the suction strainer be inspected during routine chiller operation?
  The internal suction strainer should be checked after the initial 100 hours of commissioning to clear installation debris, and subsequently inspected during annual maintenance overhauls to ensure unrestricted suction gas flow.
• What is Coolstart's warranty policy for semi-hermetic compressors?
  Coolstart provides a standard 1-year warranty covering all compressor product lines against manufacturing and material defects under normal operating conditions.
• What details are required to obtain a formal quotation from Coolstart?
