R134a Refrigerant

R134a:

Danus R134a refrigerant (chemical name as 1,1,1,2-Tetrafluoroethane) is a hydrofluorocarbon (HFC) gas, with a not relevant ODP potential. It can be used both pure as well as with blends. It is considered as one of the principle replacement products for CFC and HCFC refrigerants. It can be used at medium and high temperatures. For its energy efficiency and refrigerating capacity, the refrigerant danus R134a has similar performance to the R12 and is considered as a possible alternative to the refrigerant R12 in a wide range of applications. It and is widely used in the new installation of refrigeration and air conditioning and many automotive A/C systems.

Applications:

• Automotive
  for air conditioning units in all new generation cars

• Air conditioning
  – commercial and industrial
  air conditioning in public transport (passenger trains and buses)

• Refrigeration
  – commercial and industrial
  refrigerated counters, cold rooms, centrifugal refrigeration systems, ice makers, refrigeration systems for the processing industry, chillers
  – domestic
  domestic refrigerators

• Thermal hydraulics
  heat pumps

• Refrigerated transports

Lubricants

• PAG
  lubricant based on polyalkylen glycols mostly used by plant manufacturers specialized in the automotive sector
• POE
  lubricant based on polyol esters mostly used by manufacturers of compressors

compressors

The R134a refrigerant gas is widely used for its good coefficient of performance in any compressor type such as Rotary compressor, Screw compressor, Scroll compressor, or Reciprocating compressor.
