The Peltier series Thermoelectric Temperature Controller controls fluid temperature of adhesives, sealants, lubricants and other materials in meter, mix and dispensing systems. Uses Peltier-Seebeck effect to directly convert electrical voltage to thermal differentials. This effect, which is reversible, is said to either heat or cool fluid materials with precision to the temperature set point. Device, temperature sensor and temperature control are mounted to a manifold where fluid passes through. Manifolds can be mounted inline or on fluid dispensing equipment. May also include accessories such as fluid pressure sensors, fluid pressure gauges and inlet and outlet flow control valves.
