Customized sand/dust test chambers

Products are exposed to several atmospheric agents and to changes in temperature and humidity during their service life. Sand also produces a high degree of deterioration. ACS chambers for sand and dust tests are able to reproduce all the conditions included in the standards that require continuous ventilation (DIN 40046, MIL-STD 331 AND MIL-STD 810 C), dust drop tests (DIN 40052) and tests with irregular whiff of compressed air (SAE J 575). In addition to the standard line, ACS is able to offer customized solutions thanks to its more than 60 years of experience in designing customized environmental simulation chambers, its technical know-how and the close attention given to the requests of all our customers. Example of a chamber customized according to the specifications requested by the customer.
