Product Description
Detailed Specifications & Features
Refcomp SP4H2500 SP4H250E Semi Hermetically Sealed Compressor for Cold Room
Product Advantages
Flexible Capacity Regulation (100% / 50%)
The SP4H2500 (SP4H250E) semi hermetically sealed compressor features 2-stage capacity modulation (100% and 50%). This step regulation allows system operators to dynamically adjust cooling output to match varying thermal demands while reducing overall energy usage during partial load operation.
Advanced INT6982 Motor Protection
Integrated with an INT6982 motor protection module, this semi hermetically sealed compressor continuously monitors winding temperature and electrical parameters. It prevents motor damage from phase loss, voltage fluctuations, or thermal overloading during heavy-duty running.
Dynamic Balance & Heavy-Duty Bearings
Engineered with precision floating dynamic sleeve bearings and a counterweighted crankshaft, this 4-cylinder semi hermetically sealed compressor absorbs rotational vibration and minimizes journal friction, extending component life in demanding refrigeration duties.
Applications
- Commercial Central HVAC: Ideal for medium-to-large water chillers and commercial air conditioning units requiring variable output matching.
- Cold Storage Warehousing: Serves food storage facilities and agricultural holding rooms that require continuous medium/high-temperature cooling.
- Industrial Process Cooling: Provides reliable fluid temperature control for plastic processing, chemical manufacturing, and pharmaceutical applications.
- Supermarket Display Racks: Integrates into multi-compressor parallel rack systems to deliver reliable refrigeration for display cases.

Frequently Asked Questions
Q1: How does the SP4H2500 semi hermetically sealed compressor maintain energy efficiency under variable thermal load conditions?
A1: It utilizes two-stage capacity control (100% and 50%) to step down gas displacement during lighter load periods, avoiding unnecessary power consumption and frequent motor cycles.
Q2: Is this compressor capable of managing high-load continuous duty in industrial liquid chillers?
A2: Yes, its heavy-duty dynamic sleeve bearings, combined with custom crankshaft counterweights, minimize mechanical wear and vibration during uninterrupted continuous operation.
Q3: How does the motor protection module prevent electrical failures in high-ambient environments?
A3: The built-in INT6982 protection module actively monitors winding temperatures and phase stability, tripping safety controls before motor over-temperature or phase unbalance can cause permanent damage.
Q4: What is the lead time for standard commercial orders and samples?
A4: In-stock sample units ship within 3 days, while standard bulk production orders take 10 to 15 working days to complete.
Q5: What standard warranty policy does Ruifujie offer for export shipments?
A5: All compressors supplied by Ruifujie are backed by a standard 1-year product warranty.
