Condenser: Tube-and-fin or Parallel Flow

Chewed 71'er on Sun July 04, 2010 4:43 PM User is offline

Year: 1993
Make: Oldsmobile
Model: Cutlass Ciera
Engine Size: 3.3
Refrigerant Type: 134a
Country of Origin: United States

I understand the folks at Arizona Air have used their products on their own fleet vehicles (and what better environment: Arizona). Due to the nature of 134a, it was noted that a parallel flow condenser provides better cooling than tube-and-fin or serpentine units. Is there any evidence that this contributes to compressor longevity? Admittedly, this may have little effect, as condenser is 'downstream' of compressor. Also, which is a better lubricant, BAV 100 or PAG? Thanks for your comments.

A veined PF condenser allows is for a system designed with R12 components! The ability to have proper heat reduction with the OEM spec on refrigerant! That is what allows for longevity of the compressor. Proper oil amount and refrigerant to carry it though out the system. Oils can be debated all day by chemists. We have had great results over 15 years now using the BVA in both conversions and OEM R134a systems.

PS: Our company is Arizona Mobile Air. There is an Arizona Air but not sure what oil they use with their products.

BVA markets both PAG's and POE's. BVA is a ISO certified company that produces chemicals for major OE markets as well as the aftermarket. The choice between PAG's and POE's has and will continue to be a subject of much discussion. However, BVA produces the best lubricant chemicals in the market today, IMLTHO.
