Climate chamber

Various climatic chambers for temperature / humidity storage. Measurements of heat transfer through wall constructions against indoor climate are possible. The temperature can be adjusted from -80 ° C up to + 180 ° C and range from + 10 ° C to + 95 ° C The humidity can be adjusted between values of 10% and 98% relative humidity. Fast heating and cooling rates of up to 3 K / min allow rapid temperature changes.

Temperature cabinets

Temperature storage and solvent and detergent resistance tests are performed in a temperature cabinet within the temperature range of + 30 ° C to + 250 ° C. In addition to maintaining a constant temperature, it is possible to schedule different temperature programs with multiple ramps/increase and hold phases.
