At NP Plastics, we recently installed a new, state-of-the-art process cooling system. In line with our sustainability goals, we opted in favor of an integrated closed-loop system including a so called free cooler. The free cooler consists of five modules that have been installed on the rooftop and enables use to be made, when available, of low ambient air temperatures to cool the water in the process cooling circuit.
It is a highly economical solution, and one giving us energy savings of up to 25%. By installing the free cooling units on the roof, we were also able to increase the efficiency of the free cooler.
The new process cooling unit offers another advantage, as well: next to being efficient, it operates far more quietly than the old system, considerably reducing the proximity noise levels. Which is also excellent news for the neighbors: the noise impact of the new unit is much lower for them, as well.
