The most widely used industrial heat exchanger — efficient inter-fluid heat transfer through a solid wall, across chemical plants, refineries, power plants, and HVAC systems.
A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils.
SEMCO Process Equipment
Shell & Tube Heat Exchangers
SEMCO manufactures Shell & Tube Heat Exchangers in accordance with TEMA (Tubular Exchanger Manufacturers Association) standards, including Class R (refinery), Class C (general chemical), and Class B (chemical process).
Absolutely. Depending on the process fluid, we fabricate tube bundles and shells from corrosion-resistant alloys including SS 316L, Duplex steel, Titanium, and Hastelloy.
Custom-engineered ethoxylation systems for safe, precise reaction control in non-ionic surfactant and specialty chemical production. Due to the hazardous and highly exothermic nature of the EO reaction, systems demand robust mechanical design and strict safety compliance.
Complete esterification process systems optimized for high conversion efficiency and consistent product quality. Efficiently handles the reaction between acids and alcohols with precise temperature control, effective mixing, and reliable by-product separation.
Safe, efficient sulphonation and sulphation systems for introducing sulfonic or sulfate groups into organic compounds — mainly for surfactant and detergent manufacturing. Highly exothermic processes involving corrosive chemicals, requiring precise control and superior equipment integrity.
Compact, highly efficient heat exchanger ideal for viscous fluids, slurries, and fouling services with self-cleaning channels.
Critical heat transfer equipment that supplies controlled vaporization heat to the bottom of distillation columns — generating vapor for effective mass transfer in continuous duty.
Condenses vapors or cools process fluids using ambient air — eliminating cooling water requirements with finned tube bundles and axial fans. Ideal for water-scarce locations.
