Ideal at temperatures around zero and below! Wherever there is a requirement for rapid and precise alternating heating and cooling phases using ramp operation, the cooled incubators with compressor cooling are showing their mettle - and yet operate at an extremely low noise level. Through the finely adjusted control technology the temperature accurately reaches the set point without any intermediate energetic spurts. The ICP 800, for example, requires only 21 minutes to cool down from 20 ℃ to 10 ℃, or to heat up from 20 ℃ to 37 ℃. It is obvious that only CFC-free coolants compatible with the environment are being employed.
