Residential, Commercial and Industrial positive displacement compressors for HVAC. Walk-in coolers and freezers designed to -10*F

alltemp-M description

A single component refrigerant designed to serve as a replacement for R22 in HVAC/R applications and R404a replacement in walk-in coolers and freezers

Increased energy efficiency while providing the lowest GWP of any non-flammable HFC refrigerant.

General Information

Physical Properties

What is alltemp™?

alltemp™ is a patented line of refrigerants that are composed of modified R-134a that is permanently bonded with a halo-alkaline complex manufactured to be a drop in replacements for R-22, R-134a, R-404a and R-407a/c that provides energy savings through reduced compressor amp draw an increased capacity.

What does alltemp™ do?

alltemp™ reduces compressor lift, reducing the amperage required to power the compressor while simultaneously increasing the capacity of the system over the native refrigerant, decreasing compressor runtimes. Both these benefits together combine to provide an average savings of 27%.

Why do our customers need alltemp™?

Customers using R22 are in a predicament. The Montreal Protocol targets the manufacturing of HCFC’s, specifically R22, to be phased out by 2020, as well as reducing the amount of R22 that’s allowed to be imported into the United States. As supplies of R22 are reduced, costs are increased leading to the increased costs of maintaining existing R22 equipment. On the other side, customers can replace their R22 equipment, but at high costs and the majority of the equipment that is available for replacement is also being scheduled for phase-out, which leaves the customer in the position of buying new equipment that will also see costs increase to maintain it.

This is where alltemp™ fits into the equation. As a true drop in replacement, when alltemp is installed into existing HVAC equipment, it recertifies the equipment to be R-134a, which protects it from phase-out requirements. On top of insulating your equipment from the rising costs of R-22, alltemp provides energy significant energy savings without making any modifications to the existing equipment.


More Frequently Ask Questions

How is alltemp™ made?

By bonding R-134a with a proprietary Halo-Alkaline complex through heat and pressure

What is a Halo-Alkaline complex?

A blend of organic oils. alltemp’s  complex is a proprietary blend

Why are you calling it R134a if it is not R134a?

Legally, we are required to classify alltemp as R134a, based on the test and protocols established by the EPA and ANSI/ASHRAE.

Why is alltemp™ different than competing refrigerants?

alltemp™ is different in many ways, but the main differences are:

  • alltemp™ is not a blend, so there is no glide and efficiency loss at high temperatures;
  • alltemp™ does not require compressor oil change in mineral oil systems, reducing the time and costs of installation;
  • alltemp™ does not lose capacity compared to the native refrigerant being replaced
  • alltemp™ was designed to provide energy savings and not to be just a drop in replacement.
What certifications has alltemp™ received?
  • alltemp™ has been certified by Intertek to have an AHRI classification of R-134a.
  • AHRI 86 – using POE lubricant in place of mineral oil and alltemp in place of R22
  • AHRI 97 – aging of copper, aluminum and steel in alltemp without changes
  • GWP – Interek certified 1151 GWP. Lowest of any non-flammable HFC
  • AHRI 210/240 showing a 21% increase in EER/SEER rating of R22 equipment
Why haven’t any OEM endorsed alltemp?

OEM’s are in the business of selling new equipment, not extending the life of existing equipment. With the implementation of the Montreal Protocol, the largest refrigerant manufacturers moved toward a new refrigerant type, hydrofluoroolefins

(HFOs), to replace HFCs and HCFCs.  These new refrigerants are enabling manufactures to sell new equipment and new gases, increasing their revenues. They now consider HFC’s as a backwards refrigerant and will no longer certify new replacements that can jeopardize their significant investments in new refrigerants.


What type of systems can alltemp operate?

Positive displacement systems only. alltemp runs at lower pressure than R22 and R404a, so depending on the system setup, fan controls, or head master setting may need to be adjusted. In HVAC, alltemp, to date, has not required any changes. In walk-in coolers and freezers, a chance to the powerhead will allow alltemp to work in a wide range of operating temperatures.


What you will notice?

An Immediate reduction in compressor amps along with a quieter sounding compressor and lower pressures. Approximately 24 hours after initial installation, a further reduction in amps will be realized. That is because alltemp is “treating” the inside of the system, which helps increase heat transfer as well as reduced friction inside the system.

Testing that has been done

Extensive M&V has been conducted, ranging from 1.5-ton split systems up to 500-ton chillers (air and water cooled) and everything in between. Reports can be found on our website and data can be provided upon request.

Will installing alltemp affect my warranty?

Most R22 systems are beyond the manufacturer’s warranty period.  CSES is working with an insurance company to provide compressor coverage for the amount of time remaining from the manufacturer when alltemp is installed during that remaining timeframe.  CSES can provide liability coverage in the unlikely event, alltemp® is the cause of equipment failure.


If your system is currently running R-134a, alltemp WILL NOT void your warranty, per Magnusson-Moss Warranty Act.
