Open-type Single-Stage Screw Refrigeration Compressor Unit

For industrial refrigeration systems that demand long-term reliability and stable capacity output, Lynxcool supplies the Open-type Single-Stage Screw Refrigeration Compressor Unit as a core component for cold storage, food processing, marine, and chemical process cooling applications. This unit is designed to operate continuously under heavy load conditions, with a cast iron housing and precision-machined rotors that maintain efficiency across a wide evaporating temperature range.

When you evaluate an Refrigeration Compressor Unit for your facility, the key performance indicators are volumetric efficiency, vibration level, and adaptability to different refrigerants. Our SRM series delivers on all three fronts. The 5+7 'i'-type rotor profile reduces internal leakage, improves oil separation, and keeps noise levels low even at full load. For ammonia (R717) and R404A systems, this directly translates to lower energy consumption per ton of refrigeration.

Model Specifications & Performance Data

Below are cooling capacity figures for R717 under standard conditions. We offer multiple displacement sizes so you can select the right Open-type Single-Stage Screw Refrigeration Compressor Unit without over-specifying or under-sizing your system. For R404A or other refrigerants, please contact our engineering team for customized selection.

Industrial Applications

This Open-type Single-Stage Screw Refrigeration Compressor Unit is currently used in hundreds of projects across meat processing, seafood cold storage, pharmaceutical warehousing, and offshore marine refrigeration. The open-type construction allows direct coupling to electric motors or diesel engines, making it flexible for both shore-based and vessel installations. For warehouse operators, the stable suction pressure control helps maintain consistent room temperature even when doors are frequently opened during loading and unloading.

Service and Spare Parts Support

We understand that downtime in industrial refrigeration is costly. Every Open-type Single-Stage Screw Refrigeration Compressor Unit we ship is backed by a global service network with 15 service centers. Our standard delivery includes a complete set of gaskets, bearings, and oil filters for first-year maintenance. For larger customers, we stock common spare parts in regional warehouses to reduce lead time for critical repairs. Lynxcool also provides remote diagnostic support to help your maintenance team identify issues before they cause unplanned shutdowns.

Frequently Asked Questions

What refrigerants are compatible with this unit?

The unit supports R717 (Ammonia) and R404A as standard. We can also adapt the design for R507A and other HFC refrigerants depending on your system requirements.

Can I retrofit this compressor into my existing R717 system?

Yes. We can match flanges, coupling dimensions, and oil cooling requirements to your existing piping and control panel. Please provide your current system layout for a compatibility check.

What is the typical oil change interval?

Under normal operating conditions with recommended oil quality, the interval is 8,000 to 10,000 running hours. Actual interval depends on suction superheat and discharge temperature.

Do you provide installation and commissioning support outside China?

Yes. We have experienced commissioning engineers available for on-site startup and training. Our team can also provide remote video guidance for step-by-step installation.

For a complete turnkey solution, Lynxcool also supplies matching evaporators, condensers, and cold room panels alongside the Open-type Single-Stage Screw Refrigeration Compressor Unit. This integrated approach ensures compatibility across all components and simplifies procurement, commissioning, and after-sales support for your project.
