Floor-standing laboratory chiller Ultracool UC 24

circulatingair-cooled

Product overview
LAUDA Ultracool circulation chiller UC 24 delivers precise temperature control across a wide operating range from -10 to 35 °C with a temperature stability of ±0.5 K. The unit is rated IP54 for protected outdoor installation. Standard fan control enables operation at low ambient temperatures down to -20 °C and reduces noise. The footprint has been reduced versus previous comparable models. An integrated Ethernet interface is standard; numerous options (speed-controlled pumps, flow meters, etc.) allow adaptation to application-specific requirements.
