Temprite’s coalescent oil separators set the industry standard for energy-efficient performance. Unlike conventional separators, coalescent oil separators are not dependent on velocity for efficiency, maintaining the same level of effectiveness down to 20% of maximum flow.
- The high-efficiency performance of coalescing oil separators means better heat transfer through the coils, translating into significant kW savings.
- Coalescent oil separators are ideal for OEM applications where system cleanliness is paramount..
Exceptional Performance Range
Temprite products improve refrigeration system thermal efficiency by minimizing oil and dirt in the system’s evaporator. The result is shorter compressor run times, reduced carbon emissions and energy consumption, and the highest possible return on investment.
Clean & Green Refrigerant Conversions
When changing from obsolete refrigerants, make your system as clean, green and efficient as possible by converting to Temprite coalescent oil separators.
Oil Separators • Oil Reservoirs • Liquid Receivers • Oil Management Products
The 130 Series offers a range of products for transcritical applications up to 140 bar (2030 PSI)** and is engineered for large-system efficiency.
*Model 131 is hermetic and the filter is not accessible for changing.
**See Model 131 and Model 139A pages for maximum working pressure options.
Innovative technology combined with superior design and manufacturing make Temprite coalescent oil separators the most energy-efficient separators available.
- Temprite coalescent oil separators separate and clean oil at a nominal 98.5%+ efficiency level.
- Coalescent oil separators maintain the same level of effectiveness down to 20% of maximum flow.
All Temprite coalescent oil separators are equipped with the Temprite Standard Filter. The Standard Filter uses a matrix-type borosilicate glass fiber material to do the work formerly done by impingement screens in conventional oil separators.
Illustration #1 shows how a coalescent oil separator moves oil-laden refrigerant gas into the filter and through the separator. Refrigerant mass flow pressure moves the aerosolized oil into the separator. Oil droplets separate from the refrigerant gas flow as they enter the filter, where the oil is stripped from the refrigerant gas. These larger, heavier droplets accumulate at the edge of the filter and then fall into the Wet Zone, collecting at the bottom of the separator where the clean oil is returned to the compressor. The clean refrigerant gas (Dry Zone) moves upward through the separator and back to the condenser.
Illustration #2 shows a cross-section of a Temprite Standard Filter. System pressure moves the refrigerant oil in aerosol form outward from the center of the filter. The filter’s borosilicate fiber matrix causes the aerosolized oil to vibrate and collide with other oil molecules, creating bigger oil droplets. As the oil droplets are pushed to the outer edges of the filter by refrigerant flow, the accumulated droplets fall to the bottom of the separator through gravitational setting.
Typical Aerosol Distribution in Mass Flow
Illustration #3 shows micron particle sizes in a typical aerosol distribution ranging from .01 to 100 microns (µm) in size. Tobacco smoke and milled flour particle sizes are given as a reference point. The majority of oil particles in refrigerant discharge gas are in the 0.4 to 10 µm range, with more than 50% of the particles less than 1 µm in size. When evaluating the efficiency of your current separator, compare the micron cleaning range of your separator to Temprite coalescent oil separators.
- Temprite Standard Filter technology cleans contaminants down to 0.3 microns in size.
Exceptional Contaminant Removal
Two of the biggest energy drains on any refrigeration system are dirt and contaminants and excess refrigerant oil. In addition, the new refrigerants coming onto the market have an enhanced solvent effect, meaning more contaminants than ever can be clogging your system.
Illustration #4 compares the filtration levels of all other types of separators to coalescent oil separators. Temprite filtration gives you the cleanest possible oil and refrigerant gas — the keys to energy efficiency, lower carbon emissions and longer compressor life.
