CSTR Pressure Reactor

Abrasion-resistant materials and custom size.

Continuous Stirred Tank Reactor (CSTR)

Our pressure reactors are custom-made to handle different chemicals and liquids without corroding or giving into extreme temperatures in the work environment. We use stainless steel and other wear-resistant materials to maintain the integrity of the tank for constant usage. Along with storage purposes, our tanks can help keep the mixtures inside cooler or warmer, depending on your settings for the wet grinding machinery.

Allwin maintains premium quality through our strict selection of suppliers and precise manufacturing capabilities in our automated production lines. As our tanks are made within one roof, we can make multiple sets of CSTR Reactors at affordable price, helping distributors focus more on their business and reduce costs for plants.

Productive CSTR Pressure Reactors

A continuous stirred tank reactor is a highly effective and easy-to-handle machine for blending all sorts of liquids (including chemicals, solvents, and reactants). Its construction consists of a vessel into which liquids are poured with a reactor installed inside it.

The stable work of the reactor allows for achieving more effective mixing, which results in a better reaction between blending chemical components. The machine functions under stable conditions continuously to get ideally mixed substances and avoid sediment.

  • The CSTR tank is made of stainless steel SUS 304/316.
  • The volume capacity ranges between 100-1500 l.
  • The body thickness varies from 1.5 mm to 3 mm, matching with volume.
  • Its cover is mirror- or pull-polished.
  • Two types of bottoms are possible, namely, flat and arch ones.

Customized Stirred Tank Reactors to Meet Your Needs

When applying the machine for production needs, customization comes as a key aspect for long-term operation, since different production processes require specific modifications. The customization process allows for dealing with a wide range of tasks and coping with them more effectively. The following components and units can be customizable in CSTR machines:

  • the reactor tank’s shape;
  • size;
  • construction materials.

If needed, additional hardware can be added. For example, heat exchangers and agitators are attached to achieve better performance and guarantee the secure and durable operation of the machine.

Having existed on the market since 1993, our company has evolved into a large-scale enterprise for the production of durable and licensed equipment for factories, laboratories, and other facilities. Nowadays, we are a recognizable brand with a high reputation proved by years of existence in the industry.

Classification of reactor CSTR

There are three types of classifications according to different criteria. If we take into account the internal pressure during functioning, machines fall into:

  1. a positive pressure reactor;
  2. an atmosphere pressure reactor;
  3. a negative pressure reactor.

Another classification focuses on the heat transfer structure. Here, the next subtypes are pointed out:

  1. internal coil modification;
  2. jacketed kind;
  3. external half-pipe variation;
  4. combination type.

One more classification exists. In this case, technicians consider the form of agitation. Multiple kinds are available here. Here are some of them: dispersed disk, helical ribbon, anchor, paddle, or frame modifications.
