What Expander does

Expander is a privately held Brazilian industrial company founded in 1984 and headquartered in Cotia in the greater São Paulo area, with a regional operations facility in Macaé, Rio de Janeiro. For approximately 40 years, the company has developed, manufactured, and maintained heat exchangers using proprietary engineering, replacement parts, and complete technical support for industrial applications. Its customer base spans multiple enterprise verticals including power generation, oil and gas, petrochemical, naval, food, pharmaceutical, paper and cellulose, HVAC, and automotive and rail sectors across Brazil.

The company's product portfolio covers five core heat exchanger types — plate, shell-and-tube, radiator, air cooler, and condensers — built in various alloys including carbon steel, stainless steel, aluminum, brass, and copper to client specifications. These are complemented by an integrated services portfolio spanning mechanical, chemical, and ultra-high pressure hydrojet cleaning; field and factory retubing; specialized field machining; helium gas micro-leak testing; tube-to-tube testing; inspection; and tube bundle extractor rental. The technology stack includes proprietary tooling developed in-house, licensed helical baffle technology for which Expander holds the exclusive Brazilian license, authorized Danfoss D-plate plate heat exchanger technology, CTI Industries insert and liner applications (with over 40,000 inserts installed in Brazil), TAPROGGE preventive condenser cleaning systems, and Heatric heat exchanger cleaning and repair services.

Expander operates a B2B enterprise field sales model with technical sales engineers providing on-site consultation, custom solution development, and project support to industrial plants, power generation facilities, refineries, platforms, and OEMs. Revenue is generated through four streams: custom manufacturing (one-time project sales), maintenance and repair services (professional services), spare parts and components (hardware sales), and equipment rental (managed services). Pricing is quote-based and undisclosed, and customer acquisition is driven through a multilingual website with extensive local SEO, direct phone, and WhatsApp contact channels rather than e-commerce.

Products and services

• Plate-Type Heat Exchanger (Trocador de Calor Tipo Placa) Compact plate heat exchanger that promotes thermal exchange through corrugated metal plates, used in processes requiring high performance and easy maintenance in food, pharmaceutical, HVAC, chemical, and paper and cellulose sectors.
• Shell-and-Tube Heat Exchanger (Trocador de Calor Tipo Casco e Tubos) Robust shell-and-tube heat exchanger ideal for high pressures and temperatures, performing thermal exchange between fluids through internal tubes and an external shell. Widely used in heavy industry, petrochemical, naval, and paper and cellulose sectors.
• Radiator-Type Heat Exchanger (Trocador de Calor Tipo Radiador) Radiator-type heat exchanger used to cool fluids through heat exchange between liquid and air, widely applied in engines, hydraulic systems, mobile machinery, automotive, railway, and power generation sectors.
• Air Cooler Heat Exchanger (Trocador de Calor Tipo Air Cooler) Air cooler heat exchanger that uses ambient air moved by fans to cool fluids without water use, common in industrial plants, oil and gas, energy, and compression systems, providing a sustainable and low-maintenance cooling solution.
• Condensers (Condensadores) Steam condensers covering repair and retubing services; condenser retubing processes are highly costly due to production downtime and the high expenses involved in removing and replacing several tons of material per retubing.
• Mechanical Cleaning Service (Limpeza Mecânica) Light/medium preventive mechanical cleaning using metallic cleaners with gauged sizes for each tube diameter, a non-rotative process that guarantees tube integrity regardless of material.
• Chemical Cleaning Service (Limpeza Química) Chemical cleaning service that continuously updates procedures and equipment to meet technological evolution and quality demands of new projects.
• Ultra-High Pressure Hydrojet Cleaning (Limpeza com Hidrojato Ultra Pressão) Industrial technical cleaning through ultra-high pressure hydrojetting and controlled pressure, the fastest, safest, and most economical solution for surface treatment, reducing costs and increasing company profitability.
• Field Retubing Service (Retubagem de Campo) High-quality retubing, cleaning, and repair services for steam condensers and heat exchangers supplied to the entire power generation industry.
• Factory Maintenance Service (Manutenção na Fábrica) Factory maintenance services for heat exchangers, which are critical components where failure can result in millions of Reais in losses due to reduced or lost production associated with unplanned downtime.
