Product Description

Key Features

Flexible Capacity Regulation

The compressor supports four-step capacity control at 25%, 50%, 75% and 100%, with optional stepless regulation from 25% to 100%. This allows the screw refrigeration compressor to adjust its output according to changing cooling demand, improving load matching and reducing unnecessary full-load operation.

Advanced Motor Protection System

The integrated INT69 SNY protection module monitors motor operating conditions and provides protection against overheating, reverse phase and phase loss. Six series-connected PTC thermistors embedded in the motor windings provide temperature monitoring, helping safeguard the motor against excessive heat.

Integrated 100 μm Suction Filtration

The built-in 100 μm suction filter captures impurities from refrigerant gas before they enter the compression chamber, helping protect internal components and the motor. This filtration arrangement also makes routine inspection and maintenance more convenient.

Flexible Shut-Off Valve Positioning

The suction and discharge shut-off valves support 360° rotation, providing greater flexibility for refrigerant piping connections. This simplifies installation in different system layouts and allows easier access during maintenance of the screw refrigeration compressor.

Frequently Asked Questions

Q1: How do I select the right SW3H-19000 for my refrigeration project?

The SW3H-19000 is a 200 HP 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. These details help determine whether the model is suitable for your project.

Q2: Is the SW3H-19000 compatible with R134a refrigerant?

R134a is included among the refrigerants listed in the RefComp SW series documentation. An R134a screw compressor configuration can be considered for compatible chiller and refrigeration applications, subject to confirmation of the selected motor configuration and actual operating conditions.

Q3: How does capacity regulation benefit large refrigeration systems?

Capacity regulation allows compressor output to follow changing cooling demand instead of continuously operating at full capacity. Four-step or optional stepless control provides greater flexibility for large refrigeration systems with varying loads.

Q4: What maintenance should be performed on the suction filter?

Inspect the suction filter regularly, particularly when refrigerant circuit contamination is suspected. Cleaning or replacement should follow the manufacturer's maintenance recommendations to help protect the compressor's internal components.
