Temperature measuring strips, for example, are stuck to components that heat up under load. The measuring strip shows the maximum temperature reached after the component has cooled down. This means that the maximum temperature of the component can be read off quickly and inexpensively.

Most industrial process temperature control units work through the pressure exerted on the water of the process utilities: this is convenient in most “standard” cases, given the higher efficiency developed by the system. However, some critical process issues can make this type of operation difficult: this is the case of machines that leak fluids, or with leakage, and that it is not convenient to maintain on the spot. In such cases, it is therefore useful to work with a vacuum temperature control unit, which sucks in utility water. FTT PD water thermoregulators are flexible and effective systems, which can work under either pressure or vacuum depending on the peculiarities of the system. Any fluid losses are therefore minimized during operations. A simplicity of operation is also ensured by the touch-screen panel, also found on other Frigofluid temperature controllers. Models with an increased pump are also available for users characterized by high pressure drops.

Often the main critical issue for molding industries is not achieving the temperatures needed for their processes, but maintaining them over time. Hence the usefulness of temperature control units that not only send the fluids needed to do the job up to temperature, but are capable of subsequent self-tuning. This is the way FTT DC water temperature controllers operate, which wrap direct cooling to stabilize fluid grades after the desired temperature has been reached. This requires integration with a source of cooled water: a simple well or a chiller or cooling system (chiller or dry cooler). Our engineers are available to determine which cooling solution is the most effective and economical. Not only that. The management of these successive heating-cooling steps is easier when done with a touch screen: a feature with which FTT DC temperature controllers are equipped. Units in the FTT category are specially designed to condition molds.
