Continuous Stirred Tubular Reactor (cstur)
What is Continuous Stirred Tubular Reactor (cstur)
The CSTUR Reactor is a continuous flow reactor engineered for the precise manufacture of Flexible Polyurethane Foam and other demanding chemical processes. Developed by experienced flow reactor manufacturers, this system enables accurate dosing of up to seven different liquids with varying densities and viscosities, along with controlled gas injection, to ensure stable and repeatable chemical reactions.
As one of the advanced solutions offered by reactor manufacturers in India, the CSTUR is designed for versatility and reliability across a wide range of chemical reactor applications where uniform mixing, controlled residence time, and efficient heat transfer are critical.

FAQs
CSTUR reactors are constructed using high performance materials such as Austenitic Stainless Steel, Hastelloy, Inconel, Monel, and other corrosion resistant alloys. The selection depends on operating pressure, temperature, and chemical compatibility.
CSTUR systems are widely used in the chemical, pharmaceutical, and speciality materials manufacturing industries. Applications include polyurethane production, halogenation reactions, and gas-generation processes under controlled conditions.

Temperature directly influences reaction rate, product selectivity, and safety. In a CSTUR, precise temperature control through jackets or shaft heating and cooling ensures stable reaction conditions, efficient heat removal, and reduced risk of thermal runaway.
CSTUR and PFR serve different process requirements. A CSTUR offers superior mixing and better control for reactions involving multiple feeds, gas injection, or viscosity changes. A PFR is preferred for simpler reactions with minimal mixing requirements. The choice depends on reaction kinetics, heat transfer needs, and process complexity.
