All of the components may be operational, but are they adjusted and working properly as a complete system? A professional installation will include a thorough inspection of the system as a complete unit.

SensoTech’s LiquiSonic® analyzer allows for precision measurement of oil concentration in refrigerant to ensure the optimum ratio of oil and refrigerant. According to SensoTech, the LiquiSonic sensors use ultrasonic technology to continuously and directly measure the oil concentration.

The Appliance Standards and Rulemaking Federal Advisory Committee (ASRAC) has approved an agreement reached by manufacturers and energy efficiency advocates acting as part of a working group to set new energy efficiency standards for walk-in coolers and freezers (WICF).

With the advancing worldwide phaseout of hydrochlorofluorocarbons (HCFCs), the United Nations Environmental Programme (UNEP’s) OzonAction Division of Technology has produced a series of factsheets on the safe use of the new alternative refrigerants.

The refrigeration industry certainly takes its share of heat from the scientific research community, and it can be easy to feel as if we’re being ganged up on. But the good news is that we’ve got some scientists and researchers working on our side, too.

The Carel HEOS Sistema is a high-efficiency solution for refrigerated cases. It features remote cases fitted with variable-speed BLDC compressors cooled by a water loop. Each case can adapt its operating pressure to the load conditions in real time, allowing the compressor to operate in the most energy-advantageous conditions.

ComStar International is introducing two new refrigerants. RS-44B (R-453A) is a low-global warming potential (GWP), energy-saving HFC refrigerant that replaces R-22 in a/c and refrigeration applications without an oil or component change.
