Hydrogen-helium dual-detection sniffer leak detector ASM 306 S is used in air-conditioning and refrigeration related applications
The tightness of refrigeration and cooling systems is described by the mass loss that occurs over a certain period of time. In refrigeration and air conditioning technology,system refrigerant losses are measured in grams per year (g/y). In homes and small Restaurants and shops can tolerate a refrigerant loss of 2 to 5 g/y. If the refrigerant loss is converted into an equivalent leak rate with a tracer gas concentration of 100%,this is equivalent to1-5X10-5?mbar?l/s?leak rate. Leak rate limits for leak testing procedures in production are thus specified. In commercial applications such as hotels,office buildings and hospitals,the size and complexity of the systems are different from residential applications. Therefore,these systems are less sensitive to leaks higher. In summary,the maximum allowable refrigerant loss in these situations is5 to 15 g/y. In the industrial sector,the total potential leakage for refrigerant loss is 15 to 30 g/y. This is relevant for chemical processes using large-scale process refrigeration.

The sniffer leak detector ASM 306 S is used here to test the various soldered and welded points mentioned above as well as valves and connections. Leak testing with helium or hydrogen sniffer probes is far superior in terms of response time,accuracy and sensitivity Compared to traditional leak detection methods (such as water bath method or pressure test),for such applications,the sniffer leak detector ASM 306S is designed for 24-hour use,even in harsh environments. With itsHigh sensitivity of 0.2 g/y,it can make accurate measurements that meet the stringent requirements of air conditioning and refrigeration applications. The instrument is designed for fast and repeatable measurements,and can be recovered in a short time even in the event of a large leak,ensuring higher operations availability,while reducing maintenance and service costs. Users will benefit from higher benefits due to maintenance intervals and easier replacement of worn parts.
