Prior to cyclic corrosion testing, conventional salt spray (a continuous salt spray at 35˚C), was the standard way to simulate corrosion in a lab. Because conventional salt spray methods failed to mimic the natural wet/dry cycles of the outdoors, test results frequently provided poor correlation to outdoors.
In a cyclic corrosion cabinets, specimens are exposed to a series of different environments in a repetitive cycle that mimics the outdoors. Simple cycles, such as Prohesion, may consist of cycling between salt fog and dry conditions. More sophisticated automotive methods may call for multi-step cycles that incorporate humidity or condensation, along with salt spray and dry-off.
Within one chamber, it is possible to cycle through a series of the most significant corrosion environments. Even extremely complex test cycles can easily be programmed with the controller. Biuged CCT Cabinets can perform salt spray, Prohesion, and 100% humidity for most cyclic automotive tests.
Easy Programming and Sample Mounting
The CCT Cabinet is designed to cycle between four conditions: Fog, Dry-Off, 100% Humidity (Model CCT only), and Dwell. Test conditions, time, and temperature are controlled by a built-in microprocessor. A remarkably simple user interface allows for easy user programming and operation. The operator can quickly create new cycles, or run any of the programmed cycles. The controller includes complete self-diagnostics, including warning messages, routine service reminders and safety shut down.
Precise Control of Fog Dispersion
The cyclic corrosion cabinet has superior fog dispersion compared to conventional systems, which cannot vary volume and distance independently. A variable speed peristaltic pump controls the amount of corrosive solution delivered to the spray atomizer, while the air pressure regulator controls the distance of the “throw.” Note that purified water is required for proper operation of corrosion testers.
Internal Solution Reservoir
Space utilization is maximized and maintenance is minimized with the cabinet’s internal solution reservoir. The 120 liter reservoir has enough capacity for running most tests for 7 days or more. The reservoir has an integral salt filter and a built-in alarm to alert the operator when the solution is low.
CCT can change temperatures exceptionally fast because of their unique internal chamber heater and their high volume cooling/dry-off blower. An additional air heater allows very low humidity dry-off exposures. Conventional chambers with water jackets cannot cycle rapidly because of the thermal mass of the water, nor can they produce low humidity.
Biuged’s cyclic corrosion testers offer state of the art corrosion testing technology, reliability, ease of operation and easy maintenance – all at a remarkably affordable price.
