Service offer for leak detection and tightness test

Leak detection and tightness tests are interesting for many areas of technology, e.g. vacuum technology, refrigeration and construction of chemical plants, reservoir plants, power stations or tanks. Depending on the task we offer:

Development of tightness test technologies (according to DIN EN 1779, DIN EN 13185)
Coarse leak detection: vacuum pressure rise test, pressure drop test and ultrasonic test
Bubble detection: immersion or application of liquid (method C1, C2 according to DIN EN 1779)
Vacuum tightness test with helium gas detector (method A3, B2.1 according to DIN EN 1779)
Fine leak detection with selective gas detectors (method B4 according to DIN EN 1779)
Tightness tests with vacuum chamber or flexible hood (method B3 according to DIN EN 1779)
Helium tightness test of components up to 180bar overpressure

Our special offer for refrigeration applications

Construction of customization tightness test benches
Development and construction of strength test stands and plants for test gas recovery
Leak detection / tightness test when using HFCs, HFC mixtures, HFO and natural refrigerants such as hydrocarbons, NH₃ and CO₂
Leak detection / tightness test with forming gas
Tightness test with mass spectrometer measurement technique for helium and higher masses
Lectures and trainings at the ILK or on the spot (also offered in cooperation with the Bundesfachschule Kälte-Klima-Technik Maintal and Niedersachswerfen)
Support of small trade and industry regarding (regular) tightness tests of refrigeration plants including processing of problems
