Static mixers are tubular internals of appropriate shape and strength to cause desired mixing and dispersion effects as the fluid flows around suitably arranged motionless mixer parts. The fluid flow is provided by pumping. In practice, small volumes, low maintenance, simple installation and cleaning and excellent reliability characterize the static mixer.

A ​​polymer cooler​​ is a type of cooling system or component that uses ​​polymers (plastics or advanced composite materials)​​ as the primary heat-exchange medium instead of traditional metals like aluminum or copper. These coolers are increasingly used in industries where lightweight, corrosion resistance, and design flexibility are critical.
