Refcomp SP4L1500 SP4L150E Chiller Reciprocating Refrigeration Compressor
Product Overview
This chiller reciprocating semi-hermetic compressor delivers reliable performance for industrial cooling applications with advanced capacity modulation and robust construction.
Two-Stage Capacity Modulation
Delivering 100% and 50% capacity steps, this compressor dynamically adjusts output to match changing thermal loads and maintain tight fluid temperature control.
High-Displacement Compression
Featuring a 4-cylinder layout delivering up to 77.6 m³/h displacement at 60Hz, optimized internal gas passages minimize pressure drop for efficient cooling.
Robust Housing & Safety Architecture
Built with a heavy-duty casing rated for 28 bar, dynamically balanced crankshafts, and an INT69B2 electronic module that protects against thermal overload.
Flexible Installation Accessories
  • 360° rotatable suction (42 mm) and exhaust (28 mm) shut-off valves
  • 230V / 150W crankcase heater for off-cycle protection
  • Internal suction gas strainer and pressure relief valve

Frequently Asked Questions
What thermal load factors should be evaluated when sizing this chiller reciprocating compressor for industrial process cooling?
Calculate total peak and partial cooling demands, fluid supply and return temperatures, mass flow rates, ambient condensing conditions, and target refrigerant properties before finalizing compressor selection.
How should electrical control panels be configured to protect this chiller reciprocating compressor during sudden voltage drops?
Install dedicated phase-monitoring relays, size circuit contactors for the 29 A maximum operating current, and configure time-delay restarts to prevent motor short-cycling.
What design steps prevent oil entrapment in liquid chiller evaporator circuits during 50% part-load operation?
Size suction piping to maintain minimum gas velocity, install proper oil traps at suction line bases, and ensure oil return sight glass levels stay within normal operating limits.
What procedures apply when replacing the crankcase heater or inspecting electrical terminal connections?
Always isolate main power prior to servicing, verify the 150W heater element resistance, and torque terminal bolts according to factory specs to prevent high-resistance electrical hot spots.
