The U.S.-based component manufacturer has added its R744 oil separator for transcritical CO2 applications. The product features the most efficient oil/refrigerant filtering and separation technology available.
Developed nearly three years ago, the 130 Series of coalescing oil separators is optimised for CO2 transcritical applications and it builds on the previous success of Temprite’s 920R series extensively used in subcritical applications for many years. Both series perform the dual functions of filtering dirt out of the refrigerant and oil along with separating the oil from the refrigerant gas. The 130 series presented on R744.com utilizes the most efficient oil-refrigerant filtering/separation technology available. Temprite’s technology achieves a 98.5%+ separation efficiency level across the widest range of mass flows. The high oil separation efficiency saves energy by minimizing the amount of oil in the evaporator which improves heat transfer efficiency. This translates into shorter compressor run times, thus saving energy and money – a further augmentation to an already environmentally friendly system! Furthermore, the separator design enables the filter element to be easily changed after it captures excess dirt circulating in the system.
An efficient oil-gas separation technology becomes both more important and challenging when using CO2 (R744), as the refrigerant has a higher density than conventional refrigerants. As opposed to conventional refrigerant gases, high-pressure CO2 installations might use pipes instead of thin-walled tubing for the connection lines, making a higher accumulation of dirt and hence a blockage of small-sized valves more likely. Temprite’s solution offers easy access to and replacement of the filter via the removable top plate. Individually adjustable mounting feet allow for variable field leveling and adjustment. The integral oil reservoir and sensor port enables the 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.
