How does fixed leak detection work?

Categories: Uncategorised.

Meet the latest member of the JAVAC leak detection family. Introducing the iSense infrared fixed leak detector The most reliable solution to refrigerant and CO2 detection With environmental impact and the F-Gas regulations becoming one of the main talking points when considering installation of any air conditioning and refrigeration equipment, it’s vital that infrared fixed leak detection is first on the list. Recognising this JAVAC has added to the already successful handheld leak detection portfolio with the inclusion of the iSense infrared fixed leak detector for refrigerants and CO2. The Technology Infrared absorption sensor technology has been the mainstay for

How to use your vacuum pump correctly

Categories: Uncategorised.

An engineer’s vacuum pump is either his best friend or his worst enemy. When it’s a straight forward connection and the system is reasonably accessible then the job is pretty straight forward. Effective dehydration prior to charging a system with refrigerant takes valuable time and time is money. As a manufacture of high vacuum pumps for over 40 years we find many problems experienced in the field are due to misunderstanding of vacuum principles. We are often asked to supply a big vacuum pump because the job is big. Vacuum pumps can be as big as chest freezers but this

Can I use my refrigeration manifold for pressure testing?

Categories: Uncategorised.

ENGINEERS UNDER PRESSURE   Steve Davies from JAVAC explains why he believes standard refrigeration service manifolds should never be used for pressure testing.   It’s always the same old story. The engineer says: “This is what I’ve always done and I’ve never had a problem.”   However, engineers who need to pressure-test the system following a repair or install are endangering their safety if they continue to use their conventional tried and tested refrigeration manifold to pressure-test with OFN (oxygen free nitrogen).   In the old days when R12 and R22 system test pressures were lower, you might have got

How to use a refrigerant leak detector

Categories: Uncategorised.

Zero in on the “impossible to find” leaks With refrigerants constantly changing which appears to be every other month, future proof refrigerant leak detectors are quickly becoming the most powerful tool in an engineer’s armoury. The last thing a refrigeration and A/C company needs is for an engineer to be spending days on end searching pipework trying to find a pinhole leak on a system. The first thing they do need is the most accurate and sensitive leak detectors for pinpointing the smallest of leaks using either heated diode or infrared sensors. Scott Davies of Javac commented “Every engineer will
