Emkarate RL Lubricant

Emkarate RL Lubricant

Video Overview

Description

The Emkarate family of lubricants is a wide range of polyol ester refrigeration oil products. They are designed specifically for use with HFC refrigerants, developed to meet the performance demands of the refrigeration industry. This superior performance is achieved with basefluids that are specifically formulated to deliver optimum performance with minimal additive levels.

The requirements of today’s refrigeration and air conditioning compressor lubricants are complex. They must be compatible and miscible with the HFC refrigerants, and they must be compatible and miscible with CFC’s and HCFC’s as well as mineral and alkylbenzene oils. Polyol ester lubricants meet these needs, and the EMKARATE RL line is the preferred choice. Working in close collaboration with compressor and system manufacturers, these OEM-approved POE lubricants cover a wide viscosity range from 7 cSt (35-40 SUS) to 220 cSt (1100 SUS) to suit most applications. The lubricants have excellent thermal and chemical stability, and are compatible with a wide range of elastomers, polymeric materials and other materials of construction. Additionally, then higher viscosity index is an indication that their effective viscosity will not change drastically with the wide swings in temperature seen by most typical refrigeration and air conditioning systems. They are the preferred choice for servicing and retrofitting existing equipment as well as for OEM charging.

Directions

This product must be used in accordance to the following directions by HVACR professionals only.

  1. Run defrost cycle on all evaporators in order to maximize the movement (return) of mineral oil to the compressor.
  2. Turn refrigeration off and isolate the compressor. Remove refrigerant from compressor via accessible ports using appropriate methods and recovery equipment. Remaining portion of CFC refrigerant will stay in the rest of the system.
  3. This “down-time” where compressor is open to atmosphere will provide for the warming of the oil in the compressor and facilitate its subsequent draining.
  4. Drain mineral oil from compressor. Where possible, drain any oil remaining in other system components such as receivers, accumulators and separators. It is recommended that this step not be rushed; taking adequate time will allow for full warming and a subsequently more complete draining of the mineral oil from the compressor. This is important, particularly on medium temp systems that may not have hot gas defrost nor electric defrost or warming.
  5. Replace with equal volume (equal to what was removed) of approved EMKARATE RL lubricant. Charge with appropriate equipment (sealed refrigeration oil pumps, etc.) and procedures.
  6. Change filter driers.
  7. Using same hand pump (Robinair, Thermal Engineering, etc.), add an additional volume of the EMKARATE RL lubricant (equal to 1/2 of what was just charged to the compressor(s) to the system’s liquid line after the condenser, and after the receiver, if there is one.
  8. Continue using the pump to adequately push this additional lubricant into the system.
  9. If there are multiple evaporators, be sure that all automatic defrosts are disengaged.
  10. Re-charge the portion of CFC that was removed from the compressor in step two. Again, use appropriate methods and equipment.
  11. Re-energize or start system, remembering that you have approximately 50% extra lubricant in the system. This additional lubricant will enable the system to be “scoured” or more efficiently cleaned of remaining mineral oil.
  12. Monitor the compressor crankcase oil level, and drain crankcase as necessary to maintain proper oil levels. In about 15-30 minutes, most of the extra lubricant, including much of the remaining mineral oil, will have been drained from the system.
  13. After 30-40 minutes, run defrost cycle(s) again to maximize oil return in the compressor(s).
  14. De-energize or turn off the system and sample the oil from the compressor crankcase; if there are multiple compressors, take a sample from each.
  15. Using your Nu-Calgon Refractometer (P/N 4815-0), test the sample(s) for residual mineral oil content. For this first test, you should not expect the residual mineral oil to automatically have reached the target of ≤5%. If you’re sampling more than one compressor, take an average of the test results.
  16. Isolate compressor once again, and recover CFC in compressor, again using appropriate procedures.
  17. Drain lubricant from compressor, and charge with an equal volume of the same EMKARATE RL lubricant.
  18. Change filter driers.
  19. Re-charge the portion of CFC that was removed from the compressor in step two. Again, use appropriate methods and equipment.
  20. Re-energize or start system, and run to achieve full circulation of lubricant/refrigeration mixture.
  21. Sample oil and test with refractometer.
    a) If mineral oil residual is below 5%, and it should be, turn system off and recover CFC appropriately. Charge system with selected HFC refrigerant.
    b) If mineral oil residual is still above 5%, and this would by very unusual, repeat Steps 15-18 and retest.
