Core offering

Heat Transfer Technology AG designs, engineers, and manufactures custom industrial heat transfer solutions built around Pillow Plate and Dimple Plate heat exchanger technology, plus a BUCO-branded line of ice-based cooling systems (Falling Film Chillers, Industrial Ice Machines, Ice Banks, Ice Bank Silos, Flake Ice Storage). All solutions are tailored in stainless steel or mild steel to customer-specific thermal, hygienic, and spatial requirements, and the company delivers them alongside conceptual design, basic engineering, process optimisation, and technical due-diligence consulting for production plants.

Product overview

Heat Transfer Technology AG offers a portfolio of industrial heat transfer solutions centred on thermo process technology and heat exchanger plate systems. The core product line consists of Dimple Plate, Pillow Plate, and Dimple Jacket heat exchanger plates made from stainless steel or mild steel, which serve as the foundational components for thermal calculations and heat transfer optimisation. These are complemented by complete Pillow Plate Heat Exchange Systems for integrated solutions. The company also provides a range of ice-based cooling solutions including Falling Film Chillers, Industrial Ice Machines, Ice Banks, Ice Bank Silos, and Flake Ice Storage Systems for industrial cooling applications. All products are custom-engineered rather than mass-produced, with optimised calculations for heat transfer and pressure drop tailored to specific customer requirements in process engineering, energy plant construction, and food technology industries.

Brands

• BUCO: Product brand representing pillow plates, dimple plates, and heat exchange systems. BUCO products symbolize technical and process-oriented consulting, thermodynamic efficiency, and quality and longevity.

Products and services

• Dimple Plate Customised heat exchanger plate with dimpled surface pattern, made in stainless steel or mild steel depending on the application, with optimised heat transfer and pressure-drop calculations for industrial thermal processes.
• Pillow Plate Single-walled or double-walled heat exchanger plate used as a heat exchanger for temperature control of products, with flexible design options for various industrial applications.
• Dimple Jacket Container wall enclosure with evenly spaced dimples that provides homogeneous temperature control by completely enclosing the product, used for efficient heating or cooling of tank contents.
• Pillow Plate Heat Exchange Systems Integrated heat exchange systems combining multiple Pillow Plates for liquids with fluctuating temperatures and heat-recovery applications, offered as complete custom-engineered solutions.
• Falling Film Chiller Continuous BUCO falling film chiller that generates water at 0.5 °C without ice formation, designed for industrial cooling applications with cleaning advantages on the heat-transfer surface.
• Industrial Ice Machines Fully automated BUCO industrial ice production systems operating in pumped mode for continuous ice generation, producing ice at half the operating cost compared to drum systems.
• Ice Bank BUCO ice storage system with a consistently large ice surface that ensures the fastest possible product cooling even with a small refrigeration system, handling load peaks efficiently.
• Ice Bank Silo Large-capacity BUCO ice silo with extremely large ice surface for the fastest possible product cooling with small refrigeration systems during extreme load peaks, made entirely of stainless steel.
• Flake Ice Storage Systems Automatic BUCO storage systems for efficient and hands-free flake ice storage, complementing ice production for professional storage in various industrial applications.
• Engineering and Process Consulting Services Project-based professional services covering conceptual design and basic engineering of new production plants, process optimisation and revamping of existing systems, energy and resource efficiency studies, and technical due diligence and plant consulting for process engineering, energy plant construction, and food technology customers.

Direct peers

• HRS Heat Exchangers: Specialist in corrugated tube and scraped-surface heat exchangers for hygienic, viscous and fouling applications — competes with HTT in food, dairy and bio-process cooling where hygienic design and surface cleaning matter.
• Kelvion: Pure-play industrial heat exchanger manufacturer (formerly GEA Heat Exchangers) producing plate, shell-and-tube and welded heat exchangers for food, dairy, chemical and HVAC applications — the closest direct head-to-head competitor to HTT in plate heat exchangers.
• SPX Heat Transfer (APV/SPX): Industrial plate and scraped-surface heat exchanger maker (APV heritage) with deep dairy and beverage installed base — directly competes with HTT on plate heat exchangers for hygienic process cooling.
• Funke Wärmeaustauscher: German manufacturer of plate heat exchangers and bolted/laser-welded designs serving process industries — a comparable specialized player with similar product technology and European geographic footprint.
• SWEP International (Dover): Brazed plate heat exchanger specialist serving HVAC, refrigeration and process cooling — competes with HTT on compact heat exchange surfaces in refrigeration and ice-bank systems.
• Tranter (Alfa Laval): Plate heat exchanger manufacturer now part of Alfa Laval, focused on gasket, welded and brazed plate exchangers for industrial and hygienic applications — directly comparable product family to HTT's Pillow Plate / Dimple Plate range.
• API Heat Transfer: Manufacturer of plate, frame, shell-and-tube and welded heat exchangers for industrial process applications — comparable technology portfolio to HTT with broader geographic reach.

Emerging players

• Xchanger Inc. US-based manufacturer of heat exchangers including pillow plate designs for industrial, food and pharmaceutical applications — a more focused emerging competitor with comparable pillow plate technology.
