Designed for maximum temperatures and optimum safety, the TT-137 temperature control unit can handle water temperatures up to 320°F/ 160 °C.  This unit is dutiable for molds in the plastic and die casting industries.  The closed, hot-water circuit with integral cold-water receiver in a large expansion tank eliminates the problem of cracking.  The TT-137 is guaranteed to be a leak-proof system with a leak-resistant pump, even at the maximum working temperature.  With its unique design and innovative technologies, this unit can be used and immediately switched off; there is no need to cool down the system.  All Tool-Temp temperature control units and water chillers are fitted with the self-optimizing microprocessor controller MP-888 (pictured above.)  The self-optimizing feature allows a very high regulating accuracy even at high temperatures and adheres to the set temperature independently of the consumer.
