Dairy HWS elements utilize polysulfone parts and unique element construction to meet the requirements for hot water sanitization. Comprised of high quality materials that meet 3A standards and conform to guidelines set by the Code of Federal Regulations,
Dairy HWS elements feature a patented Durasan* Cage protective sleeve that enhances element integrity by securing the spiral. In addition, the sleeve improves sanitizing effectiveness by maintaining a controlled bypass between the element and pressure vessel wall
without the use of traditional brine seals.
The Dairy HWS elements comply with:
• FDA Regulations relevant sections of 21 CFR
• EU Framework 1935/2004/EC
• Halal & Kosher certification
