Expertly engineered fluid solutions are required to answer the operational challenges and unique requirements of specialised applications and equipment.

CPI Fluid Engineering (CPI) is a global leader in researching, developing, designing and producing built-for-purpose compressor lubricants for applications that include, but are not limited to, refrigeration and freezing, air compressors and specialist gas processing.

It also produces an extensive selection of engineered solutions for various industrial equipment like hydraulics, vacuum pumps, chains, gears and thermal systems.

In this article, we’ll take an in-depth look at these fluid engineering types while examining the products and brands that CPI supplies, their characteristics and the benefits they offer. Read on to learn more.

Air compressor fluids

Air compressor oils are tailored by CPI to answer diverse requirements and challenges. It offers specialist products to perfectly match different equipment and applications.

Its purpose-built air compressor fluids are available for a wide range of compressor types including flooded rotary screw, reciprocating, centrifugal and rotary vane.

Specially engineered to hold up at high speeds and temperatures, as well as extended drain intervals, these lubricants can ensure longer lasting compressor functionality and lifespan due to exceptional water separation, rust protection, thermal stability, low volatility and resistance to wear.

Specialist gas compressor fluids

The CPI range of specialist gas compressor fluids supply a full spectrum of chemical formulations that can answer all application requirements, and deliver maximum performance from on-site equipment.

Using POA, PAG, PEG and mineral base oil technologies, CPI’s compressor lubricant range is a fit for all types of process gas and hydrocarbon applications. This includes field, transportation and storage, but also processing and refinery-based usage. CPI provides specialist gas compressor lubricants designed for a flooded rotary screw, as well as centrifugal and reciprocating compressors.

Refrigeration Lubricants

CPI is also a prominent provider of lubricants for refrigeration and air conditioning systems worldwide.

Its considerable product line is specifically engineered for a wide range of applications. These include industrial, residential and commercial refrigeration systems, as well as automotive, commercial and domestic air conditioning systems.

CPI offers lubricants for a full range of refrigerant gas types to cover all user needs. This includes the compounds HCFCs and HFCs as well as low Global Warming Potential (GWP) refrigerant types like ammonia, carbon dioxide HFO and HFO blends, among other hydrocarbons.

Food Grade Lubricants

Regulators and legislation require food production facilities to use several “food-safe” fluids for onsite equipment like gears, hydraulics, refrigeration units, chains and air compressors.

As a result, CPI has engineered lubricants that are NSF H1 & H2-certfied, along with products that are registered as Kosher and Halal – for applications that involve potential incidental contact with food – as well as processes that don’t make direct contact with foodstuffs.

Additionally, CPIs range includes lubricants registered to adhere to the ISO 21469 standard, addressing the complete manufacturing process starting with formulation and correct labelling, through to risk assessment, analysis and testing.

Vacuum pump fluids

Today, vacuum pumps are used in a wide range of industrial sectors like food and chemical processing, gas and oil and pharmaceuticals, to name but a few.

Each of these applications has specialised vacuum pump performance demands. The CPI range of vacuum pump oils includes rotary vane, liquid ring, piston and rotary screw-type vacuum pumps, and is cleverly engineered to supply sought-after characteristics, like; chemical inertness; low vapour pressures; minimal carryover; oxidative stability; extended fluid lifespan and outstanding demulsibility.

Industrial lubrication fluids

Finally, CPI also provides a range of industrial lubricants designed to optimise performance.

These include synthetic gearbox lubricants that have impressive oxidative and thermal stability and enhanced gear load bearing.

It also offers a line of chain oils and hydraulic fluids that provide longer drain intervals, resulting in lower overall cost of ownership benefits These solutions retain fluidity under colder conditions, and several grades designed with potential food contact in mind are registered products with the National Sanitation Foundation (NSF).

Leading fluid brands under the CPI banner

Over the years, CPI has sought out leading fluid brands renowned for excellence and acquired them. These include Emkarate RL, Icematic and Solest.

Emkarate RL is regarded by experts in the air conditioning and refrigeration industry as a leading brand. Emkarate RL polyolester (POE) fluids have been formulated specially for use with HFC systems and hold original equipment manufacturer (OEM) approvals for a wide range of different industries. These include commercial, transport and residential air conditioning, automotive, appliance and aftermarket, as well as large industrial systems.

Icematic refrigeration compressor fluids highlight CPI’s continuing commitment to answer the requirements of transitional and long-term sustainable low global warming potential (GWP) refrigerants.

Solest is CPI’s celebrated brand of polyolester (POE) lubrication. It is formulated to supply optimum performance in both air conditioning and refrigeration compressor systems that employ HFC refrigerants.

CPI Fluid Engineering is a division of the world-class lubricant additive maker, the Lubrizol Corporation, and has earned a reputation for excellence with its efficient and high-performance products.
