Universal Parallel Flow Condensers
Parallel Flow condensers are about 1/3rd more efficient than a standard OEM Tube & Fin condenser. When converting from R12 to R134a using a Parallel Flow model condenser greatly improves performance. Parallel Flow condensers can also be used with R12 and alternative refrigerants.
It should be noted that a "True Parallel Flow" condenser is not the same as a R134a compatible condenser. 6mm dual pass and piccolo R134a compatible condensers. Though better than a standard Tube & Fin condenser. They do not perform as well as the "TRUE Parallel Flow" models we have tested.
