R456A was designed to extend the availability of R-134a in automotive MVAC while providing a cooling capacity boost for older vehicles.

R456A is a drop-in and go replacement, no oil changes or other changes are required.

Since R456A utilizes a HFO refrigerant (R-1234ze), vehicle service can utilize a value added up sale of Shrieve’s Zerol HFO additive.

R456A lowers the GWP of the R-134a system by over 50% (from GWP 1,430 to GWP 687) giving regulators peace of mind that the existing R-134a fleet will “age out” gracefully.

Benefits:

• Drop-in capability in R-134a auto
• Same efficiency as R-134a • Up to a 10% cooling capacity boost
• Non-flammable – easy conversion, same safety classification as R-134a
• Over 50% reduction in GWP – good news for future availability to service R-134a fleets
• Ability to up-sale by co-selling with value added solutions for HFO refrigerants

Application:

R456A is an ASHRAE A1 classified refrigerant (same as R-134a) that was tailored to be a drop-in replacement for R-134a in automotive air conditioning.

It shares the same energy efficiency (fuel consumption) that the vehicle was designed for by the automaker. When used as a complete replacement, by removing all R-134a and replacing with pure R456A, the cooling capacity of the vehicle is increased by approximately 10% which gives a faster cool down in the hot summer months.

However, in service it is not necessary to do a complete replacement of R-134a. Operators can top off a system with R456A or when pulled into a RRR service machine can be mixed in any proportion with R-134a.

It is advisable to label the system as containing R456A, but if a user wants to move back to R-134a this flexibility is left to the professional service garage without any special considerations.

GeneralGas KryoBox cylinders are manufactured in compliance with the European T-PED regulation and are refillable an infinite number of times.

The displayed price includes a value of 30,00 euro, corresponding to the security deposit of the empty container; this security deposit constitutes a binding modality for the return of the container for refilling purposes, as provided for by Article 11 paragraph 4 of the new Reg. (EU) Fgas 2024/573.

GeneralGas also provides an effective refill service for the empty container and subsequent return to the customer (HandyGas service), carried out at the GeneralGas plant in Cernusco sul Naviglio (MI).

Thanks to our exclusive HandyGas Refill and Redelivery service, if you return the empty KryoBox container you will be entitled to receive a new KryoBox cylinder for the price of the refill only (you will therefore only pay the value of the refrigerant gas).

Note: the cost of shipping the empty container from the customer's warehouse to the GeneralGas plant in Cernusco sul Naviglio is borne by the customer.
