Refrigeration compressors: Put your energy costs on ice

Natural refrigerants offer a significantly lower global warming potential than conventional synthetic refrigerants such as HFCs and HCFCs. However, achieving optimal compressor performance requires lubricant solutions that are fully compatible with both the refrigerant and the operating conditions. The transition to natural refrigerants creates new demands on refrigeration systems. The lubricant plays a critical role in supporting compressor reliability, efficient oil circulation and refrigerant compatibility. Reliable refrigeration compressor operation and measurable energy efficiency can go hand in hand. As industries such as food processing and chemicals increasingly adopt natural refrigerants including ammonia (NH₃) and carbon dioxide (CO₂), selecting the right refrigeration compressor oil becomes essential for maintaining reliable performance and supporting operational efficiency.

Lubrication solutions for refrigeration compressors

At Klüber Lubrication, we combine decades of application expertise with advanced lubricant technology to help refrigeration operators meet these challenges. Our specialists evaluate each application individually to identify the lubricant best suited to the compressor type, refrigerant, and operating conditions.

Our refrigeration compressor oils are engineered for use with a wide range of refrigerants and are designed to:

  • Support reliable compressor operation
  • Promote effective lubrication under demanding conditions
  • Help minimize contamination risks
  • Support efficient oil separation and recovery
  • Reduce refrigerant dilution

Beyond lubricant supply, our technical experts provide application analysis and ongoing support to help customers optimize system performance throughout the equipment lifecycle.

Your benefits: efficiency, reliability and durability

Compared with conventional mineral oils, application-specific refrigeration compressor oils can deliver significant operational benefits under suitable operating conditions.

Klüber Lubrication combines specialized lubricants, oil analysis services, and technical expertise to help customers enhance compressor reliability, improve maintenance planning, and reduce operating costs.

Key benefits include:

  • Support for extended oil service intervals in screw compressors through the Klüber Oil Condition Analysis (OCA) service, with oil lifetimes of up to 40,000 operating hours possible depending on application and operating conditions
  • Measured average energy savings exceeding 4% in refrigeration compressor applications through carefully selected lubricant solutions under representative operating conditions¹
  • Energy savings that can be measured, analysed, and documented through the Klüber Energy Efficiency methodology using a TÜV SÜD-certified process compliant with IPMVP
  • Expert lubricant analysis and technical support to support maintenance optimisation, and reliable compressor operation

Tailored solutions backed by expert analysis

At Klüber Lubrication, we do more than supply lubricants. We work alongside customers as a technical partner, helping them identify opportunities to improve reliability, efficiency, and operating performance.

By analyzing individual refrigeration systems and leveraging the expertise of our research and development teams, we identify lubrication solutions that support effective oil management, lubricant-refrigerant compatibility, and reliable compressor operation.

Leading refrigeration compressor manufacturers trust Klüber Lubrication solutions to support demanding applications worldwide.

A comprehensive lubricant analysis can help:

  • Prevent unexpected equipment failures
  • Support longer component and equipment life
  • Maintain efficient compressor performance
  • Reduce lubricant consumption through condition-based maintenance
  • Optimise maintenance planning and costs

Based on these findings, we recommend lubrication solutions tailored to the specific application, operating conditions, and performance objectives of each customer.

Reducing energy costs through efficiency

For refrigeration operators, maintaining uptime while managing energy costs is a constant challenge. Klüber Lubrication helps customers address both objectives through advanced lubrication solutions and measurable energy-efficiency services.

Depending on the application and operating conditions, our refrigeration compressor oils can:

  • Help reduce compressor energy consumption
  • Support lower operating costs
  • Improve overall energy efficiency
  • Help keep compressors and evaporators cleaner
  • Reduce the effects of refrigerant dilution

Through Klüber Energy Efficiency, potential energy savings are measured, analysed, and documented using a TÜV SÜD-certified methodology compliant with IPMVP. As a result, energy-saving opportunities can be quantified through a recognised, and transparent measurement and verification process.

By combining specialised lubrication expertise with data-driven efficiency services, Klüber Lubrication helps operators achieve measurable technical, operational, and economic benefits.
