Refcomp SP4H3000 Semi Sealed Reciprocating Compressor for Condensing Unit

Product Advantages

Optimized Gas Flow Channel & Integrated Frame
The SP4H3000 semi sealed reciprocating compressor is engineered with streamlined internal flow passages that minimize suction pressure drops and clearance volume losses. Its compact housing integrates suction strainers, pressure sensors, and shut-off valves directly into a unified body structure, maximizing physical space savings in multi-compressor rack configurations.

External High-Density Suction Filter
To guard the motor and compression chamber against circulating debris, this semi sealed reciprocating compressor incorporates an externally accessible, high-density suction strainer on the crankcase housing. This layout isolates moisture to prevent frost or dew accumulation on the inlet while allowing fast, unhassled cleaning during routine maintenance checks.

Stepwise Capacity Regulation (100% / 50%)
Featuring dual-step energy control (100% and 50%), the unit allows chiller and refrigeration systems to dynamically align gas displacement with changing thermal load requirements. Operating at partial capacity during off-peak periods cuts overall power demand and prevents unnecessary compressor short-cycling.

Applications

Commercial Central HVAC: Functions as a reliable high-capacity compressor in air-cooled and water-cooled chillers for commercial complexes.
Cold Storage Logistics: Suitable for medium-temperature agricultural holding rooms and large-scale food distribution hubs.
Industrial Process Chillers: Powers continuous industrial fluid cooling loops across plastics processing, chemical, and manufacturing plants.
Supermarket Multi-Compressor Racks: Integrates into parallel rack networks to provide consistent cooling across multiple display cases.

Frequently Asked Questions

Q1: How does the SP4H3000 semi sealed reciprocating compressor handle sudden cooling demand drops in commercial chiller systems?

A1: The unit utilizes 100% and 50% capacity step regulation, stepping down output to match reduced thermal loads without triggering motor restarts or excessive energy consumption.

Q2: What feature simplifies routine maintenance when operating in dusty industrial environments?

A2: The compressor is fitted with an externally mounted high-density suction filter on the crankcase side, allowing technicians to inspect and clean the strainer without disassembling main suction lines.

Q3: Can this 30HP compressor unit support part-winding electrical starting?

A3: Yes, its multi-voltage motor is built standard for Part-Winding starting to suppress peak starting currents.

Q4: What is the standard production lead time for commercial volume orders?

A4: Samples in stock ship within 3 days, while standard bulk production orders are dispatched within 10 to 15 working days.

Q5: What warranty protection is provided for Ruifujie compressor purchases?

A5: All products supplied by Ruifujie are backed by a standard 1-year product warranty.
