We have manufactured Single Chamber Helium Leak Testing Machines, successfully sold in Indian industries manufacturers and companies. We have designed systems for a very wide range of applications within different industrial sectors and for each of them customer satisfaction has always been our main objective.
With this objective in mind our engineers will always design the machine you require in line with your technical requirements and within your financial possibilities.- Single or multiple tracer gas systems
- Helium sniff, helium spray, helium accumulation or vacuum systems
- Spray Method: Leak rate measurement from 10-10 mbar I/s and possibility of locating the leak.
- Sniffing Method: Minimum detectable leak of 10 -6 mbar I/s and possibility of locating the leak.
- Bombing Method: The Sensitivity is limited by the internal dead volume of the part as well as on the bombing time and the pressurization value. Global test without possible location of the leak.
- Experience in Special Purpose Machines.
- From manual to fully automated solutions
- Fully or partly integrated into manufacturing lines or stand-alone systems
- Production rates to suit your needs [our fastest is 100 parts per minute]
How to select leak detection method:-Here with just various typical example of helium leak testing machine :- Refrigeration & Air Conditioning.
- Condensers : 0.1 to 3 grams / annum of gas, equivalent to around 2.0 e-5 mbar l/s of helium
- Evaporators : 0.1 to 3 grams / annum of gas, equivalent to around 2.0 e-5 mbar l/s of helium
- Compressors : 0.1 to 3 grams / annum of gas, equivalent to around 2.0 e-5 mbar l/s of helium
- Aerospace cooling systems : 0.2 micron hole, equivalent to < 1.0 e-6 mbar•l/s of helium
SF6 Circuit breaker- Leak testing is of paramount importance to ensure safe operation of the switchgear during its lifetime. 'Vacuum switchgear' must maintain their vacuum in order to prevent arcing within the switch.
- Likewise 'gas insulated switchgear' must maintain their pressure level to prevent arcing when the contacts open. Sulphur-hexafluoride (SF6) is used due to its dielectric properties. However, SF6 is a most potent greenhouse gas so cannot be released into the atmosphere. Strict control is maintained over its usage, with every gram accounted for.
- Leak rates are specified at 1% volumetric loss per annum (IEC 60694), equivalent to helium leak rates in the range of 1.0e-6 / 1.0e-7 mbarl/s
