The two most frequent questions service technicians ask about dehydration are... What size vacuum pump should be used to perform a good refrigeration/air conditioning system dehydration job? How long should the pump be left on the system to assure removal Moisture In A Refrigerant System While it is important to realize that moisture in a refrigerant system is the underlying cause of most problems and complaints, it is equally important to learn why. Basically, moisture can be cla Effects Of Pressure and Temperature on the Boiling Points of Water A high vacuum pump is capable of removing all moisture from a hermetic system by reducing internal system pressures to the boiling point of water at normal temperatures. For those being introduced he Factors Affecting The Speed At Which A Pump Can Dehydrate A Refrigerant System Several factors influence the "pumping speed" of a high vacuum pump, and thus the time required to remove all moisture from a refrigerant system. Some of the most important are: the cubic feet of the Basic Battery Care Basic Battery Care There's nothing but a loud buzzing noise coming from under the hood when you try to start your car.
