Refcomp SP4L1800 SP4L180E Semi-Hermetic Compressor for Commercial Refrigeration
Product Description
Solenoid-Driven Capacity Control: Features a solenoid-actuated energy regulation mechanism with 100% and 50% capacity steps, dynamically adjusting cooling output to match fluctuating load requirements. Modulates displacement during part-load cycles to maintain stable evaporating temperatures, prevent rapid motor cycling, and reduce operational power consumption.
Optimized Crankshaft & Reciprocating Kinematics: Engineered around a heavy-duty 4-cylinder platform with dynamically balanced crankshaft, integrated counterweights, and wear-resistant bronze wrist pin bushings. Optimized drive geometry minimizes radial friction, dampens gas pressure pulsations, and delivers exceptional mechanical endurance during continuous low-temperature duty.
INT6902 Electronic Motor Protection: Integrates an INT6902 electronic motor protection module that actively tracks motor winding temperatures and power quality, shielding the motor from thermal overheating, phase loss, and supply voltage imbalances.
Efficient Suction Gas-Cooled Motor: Built with internal flow channels that route cool returning suction gas directly across the motor housing. Designed for dual-frequency grids (400V/50Hz and 460V/60Hz PW), the multi-refrigerant motor ensures reliable performance with R22, R407C, R134a, R404A, and R507.
Applications
Commercial Frozen Logistics & Cold Rooms: Ideal for large supermarket walk-in freezers, central cold storage hubs, and food holding facilities.
Quick-Freezing Tunnels & Blast Chilling: Designed for high-capacity quick-freezing tunnels in meat, seafood, and bakery processing plants.
Parallel Multi-Compressor Rack Systems: Well-suited for supermarket parallel compressor racks subject to wide daily load swings.
Industrial Low-Temperature Process Cooling: Suitable for chemical process chilling, pharmaceutical storage, and low-temperature fluid loops.

Frequently Asked Questions
Q1: How does the 150W crankcase heater protect the 3.7 dm³ oil charge during extended idle periods?
A1: It maintains elevated oil sump temperatures to prevent liquid refrigerant condensation and migration into the oil during standby, ensuring clean oil viscosity upon startup.
Q2: What is the electrical benefit of using Part-Winding (PW) startup on this 18 HP motor?
A2: Part-Winding reduces starting current inrush to 102 A compared to 170 A in Direct-On-Line (DOL) mode, protecting local electrical distribution panels.
Q3: What routine checks should be performed on the 42 mm suction line assembly?
A3: Ensure suction flange bolts are torqued evenly, verify suction superheat levels under load, and regularly inspect the external suction filter screen.
Q4: Can Coolstart configure custom electrical junction boxes or tropicalized coatings for humid environments?
A4: Yes, we offer optional moisture-resistant terminal box seals and protective anti-corrosion exterior coatings for humid or coastal regional installations.
Q5: What standard shipping documentation is supplied with Coolstart export shipments?
A5: Every shipment includes commercial invoices, packing lists, bill of lading, factory pressure test certificates, and optional certificates of origin.
