SINGLE TEMP COMPACT WATER
COMPACT, WATER-OPERATED TEMPERATURE CONTROL SYSTEMS FOR INDUSTRIAL APPLICATIONS
The Single Temp Compact Water series offers compact, high-performance, and energy-efficient water-circulated temperature control machines. These systems are specifically designed for plastic injection moulding, extrusion, and other thermally controlled process applications, where high precision, stable temperature control, and low operating costs are critical. Compared to alternative heat transfer media such as thermal oil, water has a significantly higher specific heat capacity, enabling faster heat transfer and more stable temperature regulation. Thanks to these advantages, Compact Water systems provide ideal solutions for small to medium performance requirements.
OPERATING PRINCIPLE OF COMPACT WATER SYSTEMS
Compact Water machines operate according to a closed-loop, water-circulated temperature control principle. The system heats the circulating water to the required temperature using a specially designed heating and circulation unit. Water is then pumped into the process circuit as the heat transfer medium, where its superior thermal properties allow heat to be transferred quickly and efficiently. After delivering heat to the process, the water returns to the heating unit, completing the circulation loop.
This design ensures uniform temperature distribution, low thermal inertia, and rapid temperature response. In addition, the system operates with PID-controlled electronic circuits that minimize on/off cycling, enabling temperature stability with accuracy down to ±0.1 °C.
