Hydronic-Modules

Hydronic modules or pump stations are mostly used to maintain a certain operating pressure in branched piping systems. In combination with a heat exchanger (usually a plate heat exchanger), a 2-circuit cooling or heating system can also be set up. This is used, for example, when there is an increased risk of contamination of the cooling or heating medium with the product.

Very often, 2-circuit hydronic modules are used in the food industry and in viticulture. Here, the primary circuit of the cooling system usually contains a water-glycol mixture. Unnoticed contamination with the product can lead to possible damage to health. Instead, the product is cooled in a 2nd circuit – the secondary circuit. Water is used in this secondary circuit. A possible unnoticed contamination with water would affect the quality of the product, but would not lead to health damage.
