Peltier-Type Chiller Thermo-con Air-cooled Water-cooled Precisely control the temperature of the circulating fluid by using the Peltier device. Generates little vibration, and is refrigerant-free and environmentally friendly. Can control the temperature of the heat source by using the external temperature sensor (sold separately). (Automatically adjusts to the effects of ambient temperature.) Water-cooled Air-cooled Series HEC-A Air-cooled: Can be used in the environments with no cooling equipment. Circulating fluid Thermo-con Circulating fluid controlled to a constant temperature Water Heat source Cooling capacity: X-ray diagnostic instrument Fan Blood preservation equipment Electron microscope Peltier device (Thermo-module) Exchanges heat with the circulating fluid to maintain a constant temperature. Cools or heats the circulating fluid Series HEC-W Water-cooled: Can be used in the environments with facility water equipment. Circulating fluid Water, Fluorinated fluid 20% ethylene glycol Facility water Heat source RoHS Temperature control of chamber electrode Electron microscope Laser machining Cooling tower Temperature stability: Technical Data Added cooling capacity of 140 W and 320 W (watercooled), and 600 W (air-cooled). Temperature range setting: Related Products Can precisely control the temperature of a heat source or process fluid.

When to Use Air-Cooled and Water-Cooled Thermo-con Both air-cooled and water-cooled Thermo-cons are available. Select a proper Thermo-con by referring to the following. Air-cooled • No facility water equipment Can install the unit easily without facility water equipment. • Frequent piping changes Can reduce the piping installation labor since facility water piping is not required. Water-cooled • Need to avoid effects of ambient temperature. Since the unit is water-cooled, the ambient temperature will have little effect. • Want to reduce the installation space. Can reduce the space since the...
