Refcomp SP4HF2000 SP4HF200E 20HP AC Semi-Hermetic Compressor for Refrigeration

The SP4HF2000(SP4HF200E) semi-hermetic compressor is built for high-capacity commercial refrigeration and industrial chiller systems requiring dependable thermodynamic performance.

• Integrated Motor Protection Module: Equipped with an advanced INT6982 protector module that actively monitors winding temperature to shield the internal motor against thermal overload and phase irregularities.
• Multi-Angle Shut-Off Valves: Suction and discharge shut-off valves feature a fully rotatable mounting design that simplifies alignment with surrounding refrigeration lines.
• High-Capacity Internal Suction Strainer: High-density filter screen positioned at the housing inlet traps foreign particles before they enter the motor chamber.
• Internal Overpressure Safety Valve: Built-in pressure relief valve connects suction and discharge chambers to prevent structural damage from localized overpressure conditions.

• Commercial Water Chillers: Suitable for centralized liquid chillers and HVAC air-conditioning systems operating under high-temperature conditions.
• Industrial Process Cooling: Designed for industrial fluid chillers and process cooling systems requiring continuous, heavy-duty operation.
• Cold Storage Warehouses: Ideal for medium-temperature food holding rooms, agricultural pre-cooling facilities, and cold chain distribution centers.
• Supermarket Parallel Racks: Applicable to multi-compressor parallel rack systems feeding commercial display cases and walk-in coolers.
