Climate control of enclosures using water cooling is highly efficient, especially if there is already a central cold water supply available in the production plant.
The new Hygienic Design air/water heat exchangers from Rittal are ideally suited to the food industry, where hygiene standards are exceptionally stringent. Hygiene is an absolute must in the food industry: machinery, plant and components must readily withstand daily cleaning with pressure washers and jet steam cleaners. All surfaces must also be easy to clean, and/or designed to prevent contaminants from adhering to them.
Use water cooling to dissipate heat
Liquid cooling of enclosures offers a number of benefits: Because water has a higher thermal capacity than air, liquid cooling can dissipate large quantities of heat. What’s more, industrial environments often already have a central cooling water supply available that can be used for enclosure cooling. All that’s left to do is to mount suitable air/water heat exchangers on the enclosure. With Hygienic Design, it is particularly important that no air exchange takes place between the enclosure and the environment.
Rittal has revamped its air/water heat exchangers, and can now offer its clients in the food industry two variants of Hygienic Design. Air/water heat exchangers for wall mounting can supply cooling outputs of either 0.65 kW or 1.2 kW. The hygienic design reduces the risk of contamination in the food industry, thus helping to ensure product safety.
Modified design
Rittal has modified the design of Hygienic Design in a number of respects.
For example, the attachment to the enclosure wall using threaded bolts and nuts has been designed so that the screw fastening is not visible from the outside. The enclosure is made from stainless steel with a brushed grain size of 400, producing a surface roughness Ra of less than 0.8 µm.
