Arkema’s Forane® 427A is a new addition to the Forane line of refrigerants. Forane 427A is a new alternative for end users seeking a non-ozone depleting substitute for existing HCFC 22 applications. In addition to having comparable performance to HCFC 22, Forane 427A is one of the lowest global warming potential (GWP) HCFC 22 retrofits available on the market today, according to company spokesperson.
Forane 427A has been one of the leading HCFC 22 retrofit solutions in Europe for several years because of its ease of use in converting existing HCFC 22 systems and its proven performance. There’s no need to change the existing expansion devices in most systems. Forane 427A has good capacity and efficiency in both medium and low temperature applications, and a high tolerance to existing mineral and alkyl benzene oils, according to company spokespersons.
In addition to its comparable properties to HCFC 22, Forane 427A is EPA SNAP approved for most refrigeration and air conditioning applications. Forane 427A is a non-toxic, nonflammable, zero ozone depletion potential (ODP) refrigerant containing only HFC components. It does not contain hydrocarbons.

An infrared sensor gives technicians superior sensitivity in the field: 0.1-ounces per year. It doesn’t trigger on oil and moisture like other types of refrigerant sensors. The infrared sensor is designed to last for many years without replacing. The SRL2 has the added protection of a replaceable water-blocking filter that keeps moisture and contaminants from reaching the sensor, preventing contaminant-related failure.
Like all of the company’s instruments, the SRL2 allows field technicians to work the way they want to work. A rechargeable, 8-hour lithium-ion polymer battery powers the unit for a full day of testing. The instrument is self-calibrating and recalibrates quickly. The sturdy sensor arm is nonconductive and stays in place when positioned by the technician. Both a visual and audible alarm sound when a CFC, HFC or HCFC blend refrigerant leak is detected. Technicians have the option of muting the audible alarm.

Heatcraft sources say the motors are up to 75% efficient - that’s a 51-59% increase over shaded pole motors and a 30-35% increase over permanentsplit capacitor (PSC) motors. Heatcraft sources say the added efficiency will help end users realize lower operational costs.

The self contained units feature a stainless steel evaporator with no plating or chipping allowing for individual crescent cubes to be formed on both sides of the evaporator. The design allows for the freezing of the purest water and formation of crystal clear cubes. Front in and out airflow, slide-in door, and removable air filter allow for built-in installation. The EverCheck® Alert System sounds an audible warning when the machine is in need of service. The CycleSaver® Design allows the cuber to produce the same quantity of ice in about half the cycles of the other ice machines.

Like other Protocol units, the SP Protocol is more energy efficient than traditional condensing units for similar applications, says Hussman spokespersons. It has a reduced refrigerant charge and features 80% less leakage over parallel rack systems with similar capacities.
The flexibility of the SP Protocol allows it to be mounted indoors on top of coolers or hung from the ceiling.
The SP Protocol uses less copper refrigerant piping and fewer braze joints, is easy to service and maintain, and doesn’t need a machine room.

The P499 electronic pressure transducer from Johnson Controls is an economical direct-mount pressure sensor that’s compatible with a wide selection of HVAC and refrigeration controls and systems. Compact and rugged, this pressure transducer produces an analog signal based on a sensed pressure.
The digitally-compensated transducer is highly accurate over a broad temperature range, resisting the effects of wide ambient temperature swings, high humidity, condensation, and icing.
The pressure port is machined from a solid piece of 17-4PH stainless steel, eliminating potential of refrigerant loss caused by O-ring or weld failures and resisting damage due to physical shock, vibration, or pressure pulsations. No O-rings, organic materials, or welds are exposed to the pressure media, allowing for a leak-proof, allmetal sealed pressure system, Johnson Controls sources say.
The P499 transducer is available in several pressure ranges and output options. Pressure ranges up to 750 psig (52bar) cover the most common refrigeration and air-conditioning applications. Higher pressure ranges also available. Output options including 0.5 to 4.5 VDC ratiometric, 0 to 10 VDC and 4 to 20 mA.

The technology has been selected by The Coca-Cola® Company for use in environmentally-friendly vending machines for the 2008 Beijing Olympics as part of the global beverage company’s commitment to sustainability. The higher volumetric efficiency of CO2 refrigerant (known as R744) also means that the crosssectional area of pipes used in heat transfer equipment can be reduced.

RMS of Georgia
RMS of Georgia announces choice R-421a, a non-ozone depleting longterm replacement for R-22. The R-421a can replace R-22 with no change of oil. The R-421a can be used with mineral, AB or POE oils, is non-flammable and rated A1 by ASHRAE. It is comparable to R-22 in terms of performance across the R-22 temperature range. According to RMS of Georgia spokesperson, Choice R421a is the only R-22 replacement that contains no hydrocarbons.
