Votator® Extra Heavy Duty Series - Scraped Surface Heat Exchangers
For more than 80 years, Votator scraped surface heat exchangers have been replacing slow, inefficient batching operations with more uniform, controllable and repeatable continuous processing.
FEATURES
The Votator Extra Heavy Duty units are designed for heating and cooling products with viscosities in the 1,000,000 centipoise range. They can be specified with concentric, eccentric or oval heat transfer tubes to provide optimum processing conditions for any product.
- 3-A, ASME and PED certified
- Concentric, eccentric, and oval tube and shaft arrangements
- Heavy duty roller bearing on non-drive product head
- High torque 17-4 ph stainless steel drive end spline
- Modified motor pedestal for use with high horsepower gear drive
- Features and design options match the availability on the Votator II
Product Specifications
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.
