Calorplast USA

What Calorplast USA does

Calorplast USA is the North American subsidiary of German manufacturer CALORPLAST Wärmetechnik GmbH, specializing in corrosion-resistant plastic heat exchangers for industrial process heating, cooling, and heat recovery. The company designs and supplies immersion-type, shell-and-tube, tube plate, gas-liquid, and biogas heat exchangers built from engineered thermoplastics (PE-RT, PE-HD, PP, PVDF, PFA) and, in select high-temperature cases, stainless steel, addressing applications where metal contamination or corrosion is unacceptable. Its proprietary CALORPLAST module technology uses thin-walled tubes and patented welding/overmolding processes to deliver high heat transfer density in compact footprints, with the next-generation Evolution Series meeting Ecodesign Directive 1253/2014 (ErP 2018) standards.

The company operates a direct enterprise sales motion from its Milford, Ohio headquarters, complemented by a global distributor network spanning 12 named regional partners across EMEA and Asia-Pacific. Revenue is generated one-time per custom-engineered unit, with application-specific computer-aided design and bundled engineering consultation as core value levers. Primary customers are enterprise and government buyers in plating/metal finishing, chemical processing, semiconductor/pharmaceutical manufacturing, biogas, aquaculture, aquariums, energy storage (vanadium redox flow batteries), municipal wastewater, urban mining, and industrial ventilation — a diversified mix documented through more than 21 published case studies spanning installations in the US, Mexico, Thailand, Russia, Switzerland, Kazakhstan, and other markets.

Core offering

Calorplast USA manufactures and sells custom-engineered corrosion-resistant plastic heat exchangers for industrial applications. The company produces immersion-type, shell-and-tube, tube plate, gas-liquid (including the Evolution Series), biogas, and vanadium redox flow battery heat exchangers using engineered thermoplastics (PE-RT, PE-HD, PP, PVDF, PFA) and stainless steel. Each unit is custom-designed using computer-aided simulations to meet specific process requirements for aggressive chemical environments.

Product overview

CALORPLAST USA offers a comprehensive portfolio of corrosion-resistant plastic heat exchangers engineered for demanding industrial applications. The product line centers on five core heat exchanger types: Immersion-Type Heat Exchangers (including Standard, XS compact, and Stainless Steel variants), Tube Plate Heat Exchangers, Shell and Tube Heat Exchangers, Gas-Liquid Heat Exchangers (standard and Evolution Series), and Biogas Heat Exchangers. A specialized Vanadium Redox Flow Heat Exchanger addresses energy storage battery cooling. All products feature modular, customizable designs using engineering plastics (PE-RT, PE-HD, PP, PVDF, PFA) or stainless steel to resist corrosion and chemical attack. The Evolution Series represents the next-generation gas-liquid exchangers with enhanced efficiency, while the XS version serves space-constrained applications. Each product is custom-designed via computer-aided simulations to meet specific process requirements, with materials selected for chemical compatibility and temperature resistance ranging from -22°F to 392°F depending on material choice.
