Bimetalix manufactures a complete line of scraped surface heat exchanger cylinders for a variety of food processing applications.
TITAN™ Trimetallic Cylinder
Our patented (Patent #4,679,294) food cylinder is the most functional cylinder available. It offers the complete package for all the performance properties manufacturers are looking for. A hardened interior for abrasion resistance, a cobalt nickel alloy lining on the ID for excellent corrosion resistance, and a high strength body with good thermal heat transfer. This is all accomplished through a unique centrifugal casting process that applies the high performance alloy to the inside of a steel cylinder with both ends made from 316 stainless steel. It took three different metals, earning the name TITAN Trimetallic, to get the best performance available for your process.
Chrome Plated Cylinder
Bimetalix's standard process is to apply .003" to .006" of multi-layered hard chrome per side. Our chrome plating gives improved corrosion resistance over the base material and increased hardness to over 70 Rc, thus allowing the use of stainless wiper blades. Our final operation is to polish the chromed ID to a mirror finish. Bimetalix also offers a triple layer of chrome at a nominal cost.
Stainless Steel Cylinder
These cylinders are constructed of 316 stainless steel and are the most economical choice for end users. Stainless steel offers good strength and corrosion resistance. It does not have the heat transfer properties other cylinders offer and requires composite wiper blades due to the lower hardness of the ID. When adding the chrome plating option to these cylinders improved corrosion resistance is attained and also allows the use of stainless wiper blades.
Thin Wall Stainless Cylinder
One of the drawbacks of 316 stainless cylinders is the low coefficient of thermal heat transfer. Bimetalix uses a unique grade of high strength stainless that allows us to machine these cylinders to a smaller wall thickness without a drop in internal pressure rating. This thinner wall allows for better heat transfer. Corrosion resistance is improved over a 316 stainless steel as well. Hardness of the ID is still low which limits the use of wiper blades to only composite material. If higher hardness is required, these cylinders can be hard chrome plated.Product Comparison
