Rittal hygienic air/water heat exchangers
Rittal has revamped its air/water enclosure heat exchangers and now offers two variants of hygienic design. Air/water heat exchangers for wall mounting can supply cooling outputs of either 0.65 or 1.2 kW.
The attachment to the enclosure has been designed so that screw fastenings are 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.
The silicone seal between the enclosure and the case prevents the transfer of colourants, flavourings and unwanted odours, and eliminates gaps between the air/water heat exchanger and the enclosure. The seals are available as spare parts, easily replaced in the event of mechanical damage and dyed blue in accordance with FDA Guideline 21 CFR 177.2600. The flat seals on the water connection fittings are likewise dyed blue and geometrically designed to sit flush against the shape of the fitting. A metal-end stop prevents compression of the seal so that edges cannot protrude and allow contaminants or microorganisms to accumulate.
The top of the heat exchanger enclosure tilts forwards by 30°, preventing objects from being deposited and ensuring that liquids run off quickly. The units offer protection categories of IP56/59.
The units have C-UR and CSA approval, and the hygienic design was tested in accordance with GS-NV 6. The devices comply with standard DIN EN ISO 14159:2008 and are suitable for use in the food sector in conformity with DIN EN 1672-2:2009.
