Advantages of the UC160-190?

  • Reliable, Refrigerant-Free Thermoelectric Technology: With lifetimes exceeding 200,000 hours, the thermoelectric modules at the core of this chiller make for ultra-high intrinsic reliability 
  • Fits Inside Your Equipment: UC160-190 is less than one-sixth the size of its nearest competitor, measuring 7.5 x 5 x 7” (19 x 13 x 18 cm) and weighing only 8 lbs (3.5 kg)
  • Precise Temperature Control:  UC160-190’s digital PID control holds to ±0.1 °C through a range of 2 to 45 °C, even near ambient
  • Easy Operation: Its standard, easy-to-use RS232 communications interface and digital controller for fixed temperature control or temperature cycling make operation of UC160-190 simple.
  • Energy Efficient: Less than one-fourth the power usage of the nearest competitor (<200 W AC power)
  • Air-cooled: Does not require house or facility chilled water. Can operate in any standard room, laboratory or office
  • Lower Heat Load: Available in capacities from 160-190 Watts, well below the economical range of refrigerant-based chillers
  • Versatile: Universal power input – so OEM’s need only one model for world-wide use.  Multiple fluids:  27% propylene glycol solutions (preferred), ethylene glycol solutions
