Unitemp's new affordable corrosion chambers can simulate the effects of salt spray, fog, humidity, smoke and vehicle exhausts on materials such as paints, coatings, plastics and components
These innovative chambers manufactured by the Italian Cofomegra group are designated the corrosion box range, of which there are four models available in 400 litre and 1000 litre basic and enhanced.
The chambers can primarily fulfil three test functions which consist of a salt spray facility where a corrosive solution is turned into a vapour mist through a nozzle located in the centre of the chamber.
A fog diffusing tower distributes the fog over the entire test zone.
The compressed air required for fog production is heated and saturated with moisture in a pressurised humidifier.
The condensation water test is where the test chamber is filled with demieralised water which is then heated and evaporated condensing on the surface of the samples.
Finally the cyclic corrosion test are made possible by combining a salt spray environment with condensation humidity and air drying.
All chambers are constructed with 10mm thickness polypropylene and have a 110 litre salt solution reservoir.
Incorporated is a large glass front door for easy sample loading and viewing.
The simple to use control panel is on the top right hand side, while the salt storage tank is on the left with easy access for maintenance.
The 400 litre models have test chamber measurements of 800x700x800mm with the 1000 litre model having 1100x800x1140mm.
On the enhanced models there are 15 different test programmes with keyboard inputs and an easy to use menu.
Test status is continuously displayed on the large LCD display with folur lines of characters.
