The Smart VOV is a new refrigerant device that substantially increases air conditioning cooling at idle and city traffic conditions.
It is a self contained "drop-in" replacement for all orifice tubes; it creates colder discharge air temperatures by automatically reducing the orifice area at low compressor speeds such as when idling or driving in city traffic.
The Smart VOV variable orifice opens to a larger size at highway speeds to maintain pressures comparable to, or lower than a standard orifice tube.
Compressor life can be significantly increased because of the reduced compressor load; in hot ambient highway patrol testing, compressor failures were reduced by a factor of ten.
This innovative valve can even improve fuel economy, especially in city driving conditions.
Test vehicles equipped with Smart VOV have demonstrated excellent performance, outstanding reliability, and extended compressor life in over two million miles of severe duty desert testing.
