Temperature controllers of the teco series cd are designed for the operation with water and direct cooling up to 95 °C or 120 °C. The temperature of the process water is controlled automatically. A temperature sensor, installed inside the unit, measures available actual temperature. The microprocessor control with membrane keyboard or touchscreen operation compares measured value and preselect set value and controls heating or cooling. A trouble free operation is guaranteed by a complete safety system.

The use of direct cooling is always an advantage when a high cooling capacity is requires and the temperature differences between cooling water and circulating water are low. Here cooling water is directly and without temperature loss supplied to the circulation circuit. Absolute reliability, high regulating accuracy, easy operation and a favorable price/performance ratio: apart from the versatile performance features a modern temperature machine has to fulfill, these are the key criteria in the temperature controller wd series.

A complete centralised cooling plant, including the required peripherals, can be set up in the absolute shortest possible time at the subsequent place of installation and is immediately ready for use by means of prefabrication and installation in a container. This way, the otherwise high investments for an operating building, the costs for installation and start-up of the plant are reduced. Container cooling plants almost have no limitations in terms of their capacity and variety of possible combinations. They are supplemented by peripheral systems such as water treatment and water preparation systems or compressed air compressors. A series of different cooling systems and the combined systems composed of these units are primarily available: Chiller Heat pump systems for heat recovery Cooling tower combined with a KU system as a closed, clean cooling circuit Air heaters for direct recovery of heat hermeticool-units hermeticool hybrid-units
