About Calorifer Engineering
CALORIFER Engineering AG, headquartered in Seuzach (Canton of Zurich), develops and manufactures apparatuses and systems for process and thermal engineering. The portfolio includes shell-and-tube heat exchangers, plate heat exchangers, finned-tube and smooth-tube coils, sterilization heat exchangers, oil coolers, pressure-gas coolers and heaters as well as heat recovery systems and pressure vessels requiring inspection. In 2016, the company took over the corresponding portfolio of Calorifer AG, founded in 1951, along with its design software, order files and CAD data. Core competencies lie in thermal design, mechanical design and engineering through to 3D models and drawings in accordance with applicable codes and standards. The company deliberately does not operate its own manufacturing and produces via an established partner network in Switzerland, Austria, Germany and the Czech Republic as well as at the sister company Calorifer Heat Transfer (Jiangsu) Ltd. in Nantong, China. Customers come from the chemical, energy, refrigeration, air-conditioning and ventilation industries, machinery and plant engineering, shipbuilding and rail vehicle manufacturing.
