  • Heat exchanger inWT19 Series 19″ rack housing

    Cooling capacity from 200 W – 1,000 W

    Rack chiller for laser cooling with a temperature constancy of up to < ± 0.1 K

    A heat exchanger separates the primary circuit (to the cooling equipment) from the secondary circuit (contaminated water). Media other than water (acid, alkali, oil, DI water, etc.) can also be cooled in this way. WT 19″ rack units have generously sized components and are extremely efficient.

    Individually configurable and expandable according to customer specifications.
