We have been in the heat transfer equipment industry since Richard M. Armstrong opened our business in 1946. Although first starting as a refrigeration condenser supplier, we have slowly shifted and grown. We now pioneer vaporizers and double pipe heat exchangers. We are continuing to build our services and products.We

More than ever, companies are going to have to both increase and integrate their waste control management measures within the framework of the circular economy. When managing the reduction of air pollution, scrubbing is one method to remove pollutants from stack gases. In some cases, combining a scrubbing medium and

Melt crystallization and purification occur when a chemical mixture is cooled. The component within the mixture with the lowest solubility eventually starts to form crystals. Crystals have a standard structure, and impurities and other components do not fit within that structure. As a result, impurities assemble in the leftover liquid.

Scraped Surface Heat Exchangers (SSHE) are double pipe elements where the coolant is provided in the annulus running countercurrent to the process fluid flow.  SSHE used in the Food and Chemical Industries may differ in their materials of construction and use in many ways. Armstrong Chemtec engineers Wax Moulding Plants to

SCRAPED SURFACE HEAT EXCHANGERS Scraped Surface Heat Exchangers (SSHE) are designed to overcome process problems encountered when processing viscous fluids. During some processes, shell and tube or plate and frame heat exchangers can foul and need to be taken out of service due to reduced heat transfer capacity. SSHE, on the

Scraped Surface Heat Exchangers (SSHE) are used for continuous processing, especially crystallization and the separation of organics. Continuous cooling crystallization employs a coolant that flows through an annulus to transfer heat from the inner pipe process stream. Heat transfer is most effective at the pipe wall, and as such, crystals will preferentially

High viscosity liquids can be difficult to process, and as a result, shell and tube or plate and frame Heat Exchangers can plug. To overcome this problem, Scraped Surface Heat Exchangers provide good mixing and enhanced heat transfer, therefore avoiding plugging. Spring-loaded Blades scrape the inner pipe wall promoting good

Scrape surface heat exchangers (SSHE) are used in processes including for high viscosity and fouling fluids and for numerous continuous cooling crystallization processes. SUPERCRITICAL FLUID HEATERS Armstrong Chemtec scraped surface heat exchangers are double pipe elements designed to cool a mixture to generate the production of Crystals through Continuous Cooling of

Our continuous scraped surface heat exchangers have double pipe elements that are primarily used in duties that require viscous cooling and cooling crystallizations duties. In the device, heat transfers across inner pipe walls as coolant flows between the inner and outer pipe (annulus) with the process fluid. Outer tubes can
