Snap-on is always innovating and creating solutions for our customers. Our air conditioning units are no exception. When considering your next investment in air conditioning service equipment, an important feature is the ability to pressure test with dry nitrogen.
Just like a vehicle’s engine cooling system, leaks can occur under both positive and negative pressure. This is why we use vacuum bleeding in conjunction with pressure testers to determine the source of coolant loss.
Air conditioning systems follow the same principles. O-rings and seals tend to roll in one direction during vacuum and then move in the opposite direction under operating pressure. So, a vacuum leak test is only performing half of the inspection.
Dry nitrogen can be used in place of refrigerant for the purpose of testing for leaks under pressure. It does not react with refrigerant oil and does not alter its pressure when subjected to changes in temperature. Nitrogen exists naturally in our atmosphere, so releasing it during or after a test is completely harmless and compliant with our stringent emission control laws.
Don’t waste expensive refrigerant looking for leaks.
The Snap-on Blizzard QTech IV is equipped with dry nitrogen charging so it’s a simple case of introducing nitrogen into the system once all existing refrigerant has been evacuated. The intuitive prompts on the 7.0-inch display will guide you through.
There is no need to run the engine and compressor – once the system is full. The Blizzard Qtech IV will carry out the pressure test. If leaks are detected, the machine will give an alarm signal, discharge the nitrogen from the system, and display a system leaks alarm warning. If the test detects no leaks the machine will give no warning and discharge the nitrogen.
The Snap-on Blizzard QTech IV is an advanced air conditioning service unit available in either R134a or HFO-1234yf models. They are not only fast, intuitive, and easy to use but amongst the most modern air conditioning service and re-gassing machines in the market.
Features include Wi-Fi connectivity, a 7.0-inch colour touchscreen, 3.0m hoses, and a 12-litre refillable refrigerant tank. This automatic recovery and charging station offer a unique hybrid functionality that supports electronic-driven compressors and includes the important option to pressure test with forming gas or dry nitrogen.
If you’re looking for the latest air conditioning solution that will help your workshop become efficient and productive, then the Snap-on Blizzard QTech is the perfect choice.
