Filtrine offers three different types of chillers. Closed loop models (PCP) use a storage type cooling tank to provide close temperature control of recirculating coolants. Open loop models (POC) pump liquid from an open tank or sump, through the chiller and back to the sump. One pass models (PC) pass the liquid that needs to be cooled through the chiller only once before being added as an ingredient to a product.
