About CALGAVIN
CALGAVIN Ltd is a British engineering company founded in 1980 with worldwide representation, specialising in heat transfer solutions for the process industries. Its core product is the hiTRAN Thermal Systems for enhancing tube-side flow in shell-and-tube heat exchangers, U-tube bundles, air coolers and reactors. The service portfolio includes thermal and hydraulic design (TEMA and API heat exchangers) using HTRI Xchanger Suite, Aspen EDR and CALGAVIN.SP, CFD simulations with ANSYS CFX and Fluent, as well as on-site installation supervision. The solutions address heating, cooling, evaporation, condensation, fouling mitigation and fluid mixing. Customers include global energy companies, EPC contractors and equipment fabricators such as Siemens, Forsyths and Saint-Gobain Norpro. An in-house research and development department with test facilities, cooperation with universities, and the research partnership with RIST (South Korea) form the technological foundation.
