TLPPL 137 TECHNICO SALT SPRAY CORROSION TEST CHAMBER
Get Price Quote
Technico salt spray test chamber entire is constructed by thick polypropylene or acrylic sheet body. The top lid door will be made of transparent Acrylic. The solution reservoir is separated externally in a cylindrical vessel and fixed to the side of the main chamber. The solution is sprayed inside the chamber by means of compressed air (Air compressor not in our scope) and its level is controlled by float valve. The main chamber is provided with transparent acrylic cover lid mounted on fabricated acrylic hinges. The top lid closes the entire chamber without fog leakage. The saturation tower and the control panel are attached with the sidewall of the main chamber. The control panel is made of FRP material. Solution and water drain out tap are also provided. Suitable specimen holders and job holding devices are furnished inside the chamber. Technical Specification: Chamber temp. : 35 C Control accuracy : 3 C Saturation tower temp. : 40 C to 45 C. Controller type : PT- 100( RTD type) Temperature controller: Size : 48 x 48 mm Type : Digital Humidity Indicator: Size : 48 x 48 mm Type : Digital Digital Timer: Make : Selectron Size : 72 mm x 72 mm Hours : 999.9 hrs Pressure gauge: Range : 0 – 4.2 kg/cm2 Range : 1 kg/cm2 (saturation tower). Solution tank : 5 % of the sodium chloride (100 lit) is prepared and poured in the chamber reservoir. It is passed to the spray tower through the mechanical float through which is maintaining the water level in the tower. POWER SUPPLY: The chambers plug pin should be connected to the power supply & the timer to be set according to the testing hours. PRESSURE REGULTOR WITH GAUGE: The compressed air enters to the solenoid valve. It is controlled by the help of pressure regulator (15 lbs.) in pressure gauge. When the testing specimen or components are loaded to the chamber. The drain out valve is kept open because the condensed for water should not touch the specimens STANDARD SIZE: 600 x 600 x 600H or 600 x 900 x 900H.

CME offer both a cyclic corrosion test chamber (SF-CCT) as well as a traditional salt spray chamber (SF-SST). The SF-CCT chambers are compatible with multiple test standards including automotive standards and they can be alternated/cycled between varied humidity programs with the traditional salt spray. In recent years it has been proven that cyclic corrosion tests offer a more realistic simulation of real time corrosive environments than the traditional salt spray testing method. The salts spray test revolves around a single set point of temperature (ambient to 55oC) on the continuous mode. It lacks the role of real life conditions such as condensation humidity, air-drying etc. making the test less reliable than the cyclic corrosion test. Though CME offer both variants (cyclic corrosion test as well as salt spray test) of the chamber, it always suggests opting for SF-CCT as it is programmed to conduct a whole range of corrosion tests such as wet cycle, dry cycle, controlled humidity (optional) as well as the salt spray test in a single chamber! Built with moulded fibre, reinforced plastic and coated with automotive PU paints; the chamber’s structure offers high strength while maintaining its non-corrosive properties. The pneumatically operated translucent hood gives a clear view of the test-in progress and offers greater flexibility in specimen mounting & dismounting. During testing the atomiser sprays fine droplets (500 micron) across the test space ensuring a uniform fog collection, whereas the low-pressure vapour boiler with air circulator provides better control in the injection of moisture with minimum fluctuation. Recently the chamber has undergone a facelift based on the recently held R&D congress (at CME HQ) to eliminate the solution tank from the chamber and offer them as a separate mobile unit as per the customer’s request. This has helped in decreasing the footprint area by 30% making it more compact and consistent. Corrosion testing involves multiple test standards, which are developed by the automobile manufacturers or are according to the specific country standards. To match this diversity, CME has engineered both its SF-CCT as well as SF-SST to comply with more than 100 global test standards. It has a mix of all types of test standards ranging from ASTM, MIL, ISO, JASO to GM, NFX, AS, ECC and more.
