Compact recirculating chiller
in LE Series 19″ rack housing
Cooling capacity from 300 W – 3,000 W
Rack chiller for laser cooling with a temperature constancy of up to < ± 0.1 K
The high performance air- or water-cooled 19 inch rack chillers of the LE 19 Series not only increase productivity, reduce manufacturing costs, but also impress with their longevity and ensure aximum productivity for your laser system.
Excess heat from the laser is removed by targeted cooling with cold water from the system. LE 19 rack chillers have generously dimensioned components and are extremely efficient.
Individually configurable and expandable according to customer specifications.
