High demand for R1234yf, WAECO reports

Workshops will see a growing demand for R1234yf, WAECO has said.

A WAECO spokesperson said: “The air con service season is here and vehicles with both types of refrigerant R134a and R1234yf are now commonplace in workshops across the UK.

“Newer vehicles with their climate control systems along with hybrid and EV vehicle, thermo management system awareness, service demand is higher than ever for this lucrative opportunity.

“WAECO AirCon Service has the complete solution for all types of business, so it’s time to invest in equipment, tooling and consumables suitable for the specific requirements of servicing vehicles with R134a & R1234yf.”

Hybrid and EV vehicles have made their entrance to the automotive world and their complex cooling systems and reliance of efficiency have brought even more attention to this service opportunity.

“The servicing procedures are similar but, awareness of some differences is required in order to take advantage of this lucrative service.

“One of the most important differences is the type of lubrication oil used in AC Systems with different refrigerants and types of compressor.

“Conventional belt driven piston A/C systems typically use PAG or Ester oil, however, all hybrid vehicles require a special polyolester (POE) type oil.”

POE oil is dielectric IE has non-conductive properties, that are designed to lubricate the compressor whilst protecting the compressors electrical windings.

“Hybrid and EVs use high-voltage systems.

“Some vehicle battery’s supplying over 400 volts and above, hence different procedures should be carried out before attempting any A/C service.

“Technicians must carry out power down and disconnect supply of the system to remove any risk of electric shock when working in or around an electric compressor.

“Technicians should hold an approved hybrid/electric vehicle accreditation before working on high voltage vehicles.”

Workshops should use the correct compressor oils PAG POE when servicing, as cross contamination will reduce Its dielectric property, which are also affected if oils are not meticulously protected against moisture that is present in the atmosphere.

Contamination leads to acid formation which attacks the compressors, electrical motor windings and fine hydraulic components.

POE oil is very hygroscopic, detrimental moisture levels can occur in one day if left open to atmosphere and once absorbed cannot be removed by system evacuation even at pressure as low as 500 microns.

WAECO’s ASC range of AirCon Service Centers utilise software for hybrid service, with a flush kit (available separately) to safely change from conventional Pag oils to POE, enabling flushing of all machine pipework & hydraulic circuits to ensure no cross contamination.

OE specific oils such as Denso11 Denso 12, Sanden SPA2 RB100EV are some examples that are available in the WAECO profi oil system a truly moisture free storage which negates any waste due to moisture ingress.

Compressor manufacturers are stipulating specific oil specification that have different additives such as cleaning and molecule stabilising property’s, detergents etc.
