Cooling solutions - Import export

RAW/E liquid coolers (water, water/antifreeze) operate through a closed circuit, consisting of a finned coil crossed in countercurrent by ambient air. Due to the sizing of the coil, it is possible to achieve process fluid temperatures close to the temperature of the intake air. They are industrial chillers designed for fluids between 0°C up to 70°C, with external temperatures between -10°C and +50°C: cooling powers available as standard from 64 kWf up to 782 kWf, considering a 10°C difference between ambient air and supply water. “RAW” series chillers are environmentally friendly machines: the fluids used in the cooling process are simply water/antifreeze (fluid to be cooled) and ambient air (cooling fluid). In addition, the use of high quality materials allows the achievement of high efficiency values (ratio of kWf rendered in cooling to kW absorbed in power consumption).

The PAD-V adiabatic system is the optimal solution for increasing the efficiency of air systems, with capacities from 75 to 1,100 kW. Dry operation during cold periods: ambient air is drawn in and conveyed to the heat exchange coils (where the fluid to be cooled passes through): no water in the circuit, as during standard dry cooler operations. Energy use is also optimized by electronically modulated fan speeds based on temperatures. Adiabatic operation during hotter periods: outside air passes through the humidifier pack to be pre-cooled, before being conveyed to the finned coils and performing its cooling function: efficiency is increased. This also makes it possible to work at lower ambient temperatures.

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.
