Parallel Stream condensers are about 40% efficient than a normal OEM Tube & Fin condensers that have been used with R12 automotive refrigerants. Older condensers were constructed utilizing air conditioning a coil serpentine design, meaning one long tube was folded again and forth, with just a single path for the refrigerant to flow by way of. With the introduction of 134a refrigerants, the necessity for strain discount was required therefore the Parallel circulation condenser was developed. The modern Parallel condensers have many tubes stacked horizontally, linked to a vertical tube at every finish. Refrigerant can journey many alternative paths by way of a parallel stream condenser. Remember that true Parallel condensers are usually not the same as “134a compatible” corresponding to 6mm twin go piccolo tube condensers that were first introduced with R134 refrigerants. Our Heat Killr’ condensers are true Parallel Condensers that vastly enhance the performance of your A/C system.
