Refcomp SP4HN2000 SP4HN200E R134a High Temperature Semi Hermetic Compressor
The SP4HN2000 semi-hermetic compressor is a 4-cylinder reciprocating unit designed for high-capacity commercial liquid chilling and refrigeration systems.
Key Features
- Integrated INT6982 Motor Protection: Equipped with an advanced INT6982 protection module that continuously monitors winding temperature to safeguard the internal motor against thermal overload, phase loss, and electrical abnormalities during heavy-duty operation.
- Low-Loss Body Structure: Features an optimized gas passage layout that reduces internal suction pressure drop and flow turbulence. The compact housing integrates the suction strainer and service valves into a space-saving design ideal for multi-unit rack integration.
- 360° Rotatable Shut-Off Valves: The suction and discharge shut-off valves feature a fully rotatable mounting layout that allows simple alignment with existing refrigeration piping, simplifying field mounting and reducing mechanical strain on pipe joints.
- Internal Pressure Safety Valve: Built with a high-precision internal relief valve connecting high and low-pressure chambers, automatically equalizing pressure during temporary overpressure events to protect internal components from mechanical damage.

Frequently Asked Questions
Q1: How do I confirm if the SP4HN2000 model matches my chiller cooling capacity requirements?
A1: You can evaluate model suitability by matching your required cooling load, target operating temperatures, and refrigerant type against the compressor displacement rate. Providing target working conditions allows engineering teams to confirm exact sizing.
Q2: What key installation conditions should be checked before starting the compressor?
A2: Before initial startup, verify line connection diameters, inspect mounting pad leveling, check crankcase heater operation, and confirm that power supply panel capacity matches motor starting current requirements.
Q3: How does the internal protection module protect the motor during continuous operation?
A3: The module continuously monitors winding temperature and disconnects the control circuit during thermal spikes or electrical phase irregularities, preventing motor burnout during adverse operating conditions.
Q4: What warranty terms does Coolstart provide for semi-hermetic compressors?
A4: Coolstart provides a standard one-year warranty across all compressor product lines, covering manufacturing and material defects under standard operating conditions.
Q5: What information is needed to receive an accurate quotation for this model?
A5: Please provide your required compressor model, order quantity, target refrigerant, voltage specification, operating temperature conditions, and project requirements to receive a detailed quote within eight hours.
