The XSB150 is a 150-Watt, global ( 110-230 VAC , 50/60 Hz ) free standing, low cost thermoelectric liquid chiller system that can be used in many applications, including those in the Laser and Medical fields and Laboratory environments. These solid-state chillers are designed to use water or a coolant solution. The XSB150 chiller can also be supplied with an optional heating capability of 120 Watts. This optional provides the ability to maintain set point temperatures above ambient conditions and enables improved response time and stability for systems with varying heat load requirements.
