EMISSIONGUARD™ Family of Products

Reciprocating compressors and particularly the main pressure packing cases are known to be large contributors to the overall gas emissions from plants. For this reason, CPI have invested much time and resources to develop unique solutions to help solve this industry wide problem.

EMISSIONGUARD™ TR²

Low Emission Packing Ring

CPI’s EMISSIONGUARD™ TR² packing ring is the only ring design that multiplies the benefits of a tangent to rod ring and a step tangent ring by combining the two rings into one, providing a more efficient seal whilst reducing the frictional load onto the piston rod.

Proven in the field to consistently reduce packing case vent leakage by 50% and more.

Lubrication

 

The oil and lubrication system plays a very significant role in the performance of a reciprocating compressor. Too much, too little or inconsistent delivery can reduce performance, lead to premature wear and potentially result in catastrophic failure.

CPI provides industry leading lubrication systems, products and services, partnering with our customers to develop individual solutions to their unique lubrication needs.

From individual components to complete, turnkey systems like our SAFEGUARD™ 1000 or SAFEGUARD™ 5000 lube consoles, we can provide the resources and expertise to ensure your compressor operates at peak performance and longevity.
