About CALORIFER Engineering
CALORIFER Engineering AG, based in Seuzach, Switzerland, is an engineering partner and manufacturer of apparatuses and systems in process and thermal engineering. The portfolio covers custom heat exchangers such as shell-and-tube, finned-tube, smooth-tube and plate heat exchangers, pressure gas coolers for compressors, heat recovery systems as well as pressure vessels and skids. The core competence lies in thermal and mechanical design of pressure-vessel-grade apparatus construction; 3D models and drawings are created on the basis of proven design software, taking into account the applicable codes and customer specifications. Manufacturing is carried out via an established partner network in Switzerland, Austria, Germany and the Czech Republic as well as through the sister company CALORIFER Heat Transfer (Jiangsu) Ltd. in Nantong, China. The company belongs to the Technical Group and serves industries from power plant and chemical industries to sterilisation technology (FDA).
