Blade selection is based on many factors including compatibility with the heat exchanger tube material, product fluid characteristics, processing temperatures, and cost. Metal blades provide the best scraping properties, which means theoretically better heat transfer. However, metal blades are usually the most expensive, must run on a hard chrome surface and must be properly sharpened to avoid damaging the heat transfer tube. Today, with the development of new high temperature and FDA compliant plastic materials, there are alternatives to metal blades. The blade options below provides a wide range of our most popular blades. Many other options are also available. 6 Inch Blades
