Product Features
Compact & Rigid Casing Architecture

Engineered with a high-strength body structure rated for working pressures up to 28 bar, this semi-hermetic compressor features optimized internal flow channels that reduce gas pressure drop and flow turbulence. The compact casing integrates the suction filter, shut-off valves, and temperature sensors into a single streamlined unit, minimizing overall physical dimensions and saving valuable footprint inside equipment skids.

Solenoid-Driven Capacity Regulation (100% / 50%)

Equipped with a solenoid-controlled energy modulation system, this semi-hermetic compressor provides flexible 100% and 50% output steps. By adjusting compressor displacement directly to varying thermal loads, the system avoids frequent motor restarts, maintains stable suction pressure, and optimizes power efficiency during partial-load conditions.

Outer-Accessible High-Density Suction Filter

To safeguard internal cylinder valves and moving mechanical parts from debris, the unit incorporates an outer-accessible high-density suction filter screen. Mounted on the exterior end casing, the filter element can be easily inspected, cleaned, or replaced during routine servicing without disconnecting suction pipe lines.

Internal High-to-Low Pressure Safety Relief Valve

Designed for operational safety under extreme working conditions, the semi-hermetic compressor features an internal pressure relief valve that automatically connects the high-pressure discharge port to the suction casing during overpressure events. This internal pressure equalization prevents structural casing stress and provides reliable, self-resetting system protection.

Applications
  • Large Commercial Cold Storage Facilities - Ideal for regional distribution centers, commercial walk-in freezers, and food preservation warehouses requiring high volumetric displacement.
  • Industrial Fast-Freezing & Quick-Chilling Tunnels - Designed for flash-freezing equipment and high-capacity processing tunnels in meat, seafood, and bakery industries.
  • Parallel Multi-Compressor Supermarket Racks - Well-suited for centralized supermarket rack systems subject to significant daily load variations.
  • Low-Temperature Industrial Fluid Cooling - Suitable for chemical processing, pharmaceutical storage, and industrial liquid chilling skids.

Frequently Asked Questions
Q1: Why is the 54 mm (2-1/8") suction line dimension critical for high-displacement compressors like the SP4L2500?
A1: The 54 mm suction diameter ensures minimal vapor velocity loss across high displacement rates, maintaining volumetric efficiency and preventing starvation at the suction manifold.
Q2: How does the PW starter selection manage starting currents on 25 HP power lines?
A2: Part-Winding starting reduces peak inrush current to 123A, significantly lowering electrical voltage drops across local supply networks.
Q3: What oil separation requirements are recommended for large 102.9 m³/h systems?
A3: Due to the high volumetric gas flow, installing an efficient oil separator on the discharge line is recommended to ensure rapid oil return to the 3.7 dm³ crankcase sump.
Q4: How does Coolstart protect heavy 220 kg compressors during international freight transport?
A4: Each 220 kg unit is securely bolted onto reinforced wooden pallets and enclosed in heavy-duty export crates with internal moisture protection and dry holding gas charges.
Q5: Can Coolstart provide custom voltage configurations for 60Hz industrial grids?
A5: Yes, in addition to standard 460V/3Ph/60Hz PW options, custom motor windings for regional industrial grid voltages can be produced upon request.
