Scrape Surface Heat Exchanger, Industrial Duty

Product catalog summary

Overview: Votator® II Scraped Surface Heat Exchangers have been enhancing productivity and reducing costs in various industries for over seventy years. They are preferred for their superior heat transfer capabilities and ability to handle a wide range of viscosities, making them ideal for continuous processing of pumpable fluids or slurries.

Key Features:

High efficiency due to a large heat transfer surface in a confined space.
Rotating mutator shaft with scraper blades enhances heat transfer and product mixing.
Available in concentric, eccentric, and oval tube designs to suit different product viscosities.

Applications: Votator® II units are versatile, suitable for cooking, cooling, crystallizing, mixing, and more. They are particularly effective for heat-sensitive, viscous, particulate-laden, and crystallized products.

Component Selection:

Components are customizable to meet specific processing needs.
Pressure elements comply with ASME code and can be CE-PED certified.
Heat transfer tubes are designed for optimal thermal conductivity and durability.
Scraper blades and seals are engineered for easy maintenance and reliable operation.

Models and Specifications:

4 x 120 Model: Designed for moderately viscous products, featuring stainless steel construction, mechanical seals, and a variety of drive options.
Votator® II: Offers a range of models with different heat transfer areas and pressure capabilities, suitable for both vertical and horizontal mounting.
Extra Heavy Duty: Capable of handling extremely high viscosities, equipped with high torque drives and robust construction.

Maintenance: Votator® II units are designed for easy maintenance with features like boltless V-Lock heads, universal mounting pins for scraper blades, and easily removable heat transfer tubes.

Refrigeration Systems: The document describes gravity and liquid overfeed refrigeration systems for cooling applications.

Overview of Refrigeration Systems:
The document describes various refrigeration systems used in Votator® Scraped Surface Heat Exchangers. It highlights the thermosyphon effect in gravity systems, where vaporization reduces liquid density, promoting circulation. Surge drums regulate pressure and temperature, with options for individual or shared drums. Freeze-up protection is provided by current relay systems and optional hot gas controls.

Liquid Overfeed Refrigeration System:
This system is available on Votator® II models, utilizing a direct expansion concept where only a portion of the refrigerant is vaporized. A large low-pressure receiver separates vapor from liquid, replacing individual surge drums. Overload protection and hot gas systems are included.

Liquid/Steam Jacketing:
For optimal efficiency, a high flow rate of liquid heat transfer medium is maintained using a centrifugal pump. A controller adjusts the flow based on product temperature.

Industrial Applications:

Printing Ink Compound: Votator® units cool and crystallize products like polyethylene wax beads in solvents, crucial for high-speed printing inks.
Pelletizing: Chemical and polymer products are solidified using various cooling systems. Votator® units pre-cool viscous resins to enhance final cooling efficiency.
Chemical Reactions: Ideal for fast reactions with viscous or immiscible reactants, Votator® units ensure fine dispersion and increased yield.
Grease Production: Votator® units are used for cooling lubricating greases, ensuring consistent physical properties without fouling.
