Scraped Surface Heat Exchanger-SPK

Main feature

A horizontal scraped surface heat exchanger that can be used to heat or cool products with a viscosity of 1000 to 50000cP is especially suitable for medium viscosity products. Its horizontal design allows it to be installed in a cost-effective manner. It is also easy to repair because all components can be maintained on the ground.

Coupling connection

Durable scraper material and process

High precision machining process

Rugged heat transfer tube material and inner hole process treatment

The heat transfer tube cannot be disassembled and replaced separately

Adopt Rx series helical gear reducer

Concentric installation, higher installation requirements

Follow 3A design standards

It shares many interchangeable parts like bearing, mechanical seal and scraper blades. The basic design consists of a pipe-in-pipe cylinder with inner pipe for product and outer pipe for cooling refrigerant. A rotating shaft with scraper blades provides the necessary scraping function of heat transfer, mixing and emulsification.
