Refcomp SP4HN1000 SP4HN100E Semi-Hermetic Refrigeration Compressor for Cold Room
The SP4HN1000 semi-hermetic refrigeration compressor is a 4-cylinder unit engineered for commercial HVAC liquid chilling and medium-to-high temperature cooling systems.
Key Features
Optimized Low-Loss Gas Passage
Featuring an optimized internal flow path and integrated valve plate, this semi-hermetic refrigeration compressor reduces pressure drop and minimizes flow losses during gas intake. The streamlined housing structure saves valuable installation space inside chiller frames and multi-compressor racks.
Flexible 2-Stage Energy Regulation
Equipped with a step capacity control mechanism, the compressor switches easily between full capacity and partial output. This control allows precise output matching under changing system loads, reducing energy consumption during off-peak operation.
Internal Overpressure Safety Relief
A high-precision internal safety valve connects the high and low-pressure chambers to guard against pressure surges. The valve automatically opens to equalize internal pressure whenever safe operational limits are exceeded, then reseats securely to protect critical components.
Accessible Suction Filter System
This semi-hermetic refrigeration compressor incorporates an internal high-density suction strainer that filters out solid impurities before gas reaches the motor chamber. Located at the housing inlet, the filter element can be inspected and cleaned during routine service without removing main suction piping.
Application Areas
Commercial Water Chillers - Suitable for central HVAC chillers, packaged liquid cooling units, and air-conditioning systems.
Cold Storage Warehouses - Ideal for medium-temperature food holding facilities, agricultural post-harvest storage, and distribution centers.
Process Fluid Cooling - Designed for industrial fluid cooling equipment requiring continuous operation and precise temperature control.
Supermarket Parallel Racks - Applicable to multi-compressor rack configurations feeding commercial display cases and cold rooms.

Frequently Asked Questions
How do I verify whether the SP4HN1000 model meets my system cooling load? Evaluate required capacity, operating temperature range, and refrigerant type against the compressor displacement rate. Providing target working conditions allows engineering teams to verify exact sizing.
What key installation checks should be performed when mounting this unit? Confirm line connection diameters, inspect mounting pad leveling, and verify electrical control panel capacity against the motor starting current.
How does the internal suction filter protect the motor during commissioning? The high-density filter screen traps piping debris and contaminants carried by suction gas before entering the motor chamber, preventing mechanical damage during early operation.
What warranty terms does Coolstart offer for semi-hermetic units? Coolstart provides a standard one-year warranty across all compressor product lines covering manufacturing defects under standard operating conditions.
