All relevant kolb systems are also available in a HT = high-temperature version. (For more detailed machine information, go to "Systems" on this website).
These HT systems are especially designed for customers who only clean with hot water (e.g. because of using water-soluble flux) or work with "historic" cleaners, which have a real efficiency window only at 60-70 °C. A standard kolb system is designed for temperatures up to 55 °Celsius.
This is for a good reason: Modern state of the art detergents have a comparable degree of efficiency at a much lower temperature level. Research has made great progress in the development of these high-performance, low-temperature cleaners over the past few years. These modern, non-foaming detergents reach their application range already at 20 - 45 °C and thus the necessary viscosity to clean e.g. 4 mil or even lower standoffs. They make the process more stable, extend the service life of the cleaner, save energy machines and materials.
This development is well known from the private sector. Thanks to modern detergents and washing machines (which nowadays do not even have any 90 °C hot wash programs) laundry is washed as efficient mainly with temperatures of 30 to 40 °.
Washing with 60 instead of 90 °C saves energy between 47 and 61 percent, depending on the test-institute. The savings step down from 60 to 40 degrees is even up to 80 percent (!) and the one from 40 down to 30 degrees is at least still up to an impressive 65 percent!
Low temperature detergents, in contrast to "historical" cleaners, also contribute to a more reliable and stable cleaning performance since there is no temperature related evaporation of the detergent's water content. Only for that reason low-temperature cleaners already offer a significantly higher process stability.
kolb offers only state of the art chemistry, operating very efficient with best material protection at lower temperatures. We are always willing to run benchmark tests with all high temperature cleaners still on the market, to prove the capability and performance of our products.
