Product Description

Product Overview

The Refcomp SW3H-9000 is a 90 HP semi-hermetic screw compressor engineered for air conditioning and refrigeration applications. It combines flexible capacity regulation, integrated safety protection, and a compact, service-friendly design to deliver reliable performance across demanding cooling loads.

Key Features

Flexible Capacity Regulation

The SW3H-9000 supports four-step capacity control at 25%, 50%, 75% and 100%, with optional stepless regulation from 25% to 100%. This allows compressor output to respond to changing cooling loads, improving load matching and reducing unnecessary full-load operation.
Built-in Safety Valve Protection

The integrated safety valve connects the high- and low-pressure sides, helping prevent excessive internal pressure and providing an additional layer of mechanical protection. Its reliable pressure-relief design supports safe operation under demanding refrigeration conditions.
Flexible Shut-Off Valve Positioning

The suction and discharge shut-off valves support 360° rotation, offering greater flexibility for refrigerant piping connections. This simplifies installation in different system layouts and provides convenient access for future inspection and maintenance.
Optimized Compressor Body & Gas Passage

The optimized internal gas-passage design helps reduce flow resistance and exhaust pulsation losses while supporting effective motor cooling. The compact structural arrangement contributes to smooth compression operation and efficient system integration.

Frequently Asked Questions

Q1: How do I select the right SW3H-9000 for my refrigeration system?

The SW3H-9000 is a 90 HP semi-hermetic screw compressor designed for high-temperature refrigeration applications. Selection should consider the required cooling capacity, refrigerant, evaporating and condensing temperatures, cooling medium and electrical supply.

Q2: Is the SW3H-9000 compatible with R404A refrigerant?

R404A is included among the refrigerants listed in the RefComp SW series documentation. An R404A refrigeration screw compressor configuration can be considered for compatible commercial refrigeration applications, with the actual operating conditions confirmed during technical selection.

Q3: How does capacity regulation benefit refrigeration system operation?

Capacity regulation allows the compressor to adjust its output according to actual cooling demand. Four-step or optional stepless control helps reduce frequent full-load operation and provides greater flexibility when system loads fluctuate.

Q4: What should be considered when installing the compressor?

Check the suction and discharge piping layout, valve accessibility, electrical connections and maintenance clearance. The rotatable shut-off valves provide additional flexibility when integrating the semi-hermetic screw compressor into different refrigeration system configurations.
