MJ Gas House
Where nitrogen is used
AC and fridge technicians
Pressure testing and purging copper lines before charging gas. Nitrogen is dry and does not burn.
Tyre shops
Nitrogen tyre filling keeps the pressure steady for longer.
Food packaging
Chips, snacks and dry fruit are packed with nitrogen to stay fresh and uncrushed.
Laser cutting
Sheet metal workshops use nitrogen for clean edges on stainless steel.
Labs and IVF centres
Only high purity nitrogen for analysers and IVF incubators. Industrial grade is not used here.
Oil and ghee units
Nitrogen over storage tanks keeps air out, so oil stays fresh longer.
Pressure testing with nitrogen
Use a nitrogen regulator with a high outlet range for testing AC, fridge and gas lines.
Never use oxygen to pressure test. Oil inside the lines can catch fire.
