Model 131: Hermetic


The Model 131 coalescent oil separator for CO2 is distinctly different from the rest of the 130 Series: Model 131 is hermetic and the filter is not accessible for changing. Built for smaller systems, it delivers the same efficiency as larger Models.


  • 160 bar pressure rating
  • Compact hermetic design: 98%+ efficiency


  • Refrigerated transport
  • Refrigerant reclaim/recovery
  • Laboratory testing

The Series 130 coalescent oil separators are specifically designed for CO2 transcritical applications.


  • Application range: suitable for CO2 (R744) transcritical high- medium- and low-temperature applications
  • Dual function: filters dirt out of the refrigerant and oil; separates the oil from the refrigerant gas
  • Maximum operating pressure: 160 bar (2320 PSI)
  • Efficiency: nominal 98.5%+ separation efficiency rating
  • Filtration: sub-micron particulate retention rating
  • Connection sizes: 1/2″ NPT to 1-1/4″ NPT

*The 131 Model does not have an integral oil reservoir.


High Efficiency: most efficient oil-refrigerant filtering and separation technology with a 98.5%+ separation efficiency rating across the widest range of mass flows.

Energy-Saving: minimizes the amount of oil in the evaporator, improving heat transfer efficiency.

Cost-Saving: ensures shorter compressor run times.

CE Marked: complies with the European Pressure Equipment Directive; UL, ULC, CRN, CE and ASME approved.*
 *Contact Temprite for individual product certification details.

Easy Filter Changing: removable top plate allows for easy filter changing after it captures excess dirt circulating in the system.*
*Model 131 is hermetic and the filter is not accessible for changing. 

Individually Adjustable Mounting Feet: allow for variable field leveling and adjustment.

Internal Oil Level Monitoring: the integral oil reservoir and sensor port allows monitoring of the internal oil level and the controlled return of the cleaned oil to the compressor crank case for continued lubrication of the moving parts.
