TEWE

What TEWE does

TEWE GmbH is a Hamburg-based, family-owned industrial plant engineering firm founded in 1965 that plans, delivers, and installs process engineering systems for industrial process heat. The company serves more than 1,000 customers across Europe in verticals including food and beverage, animal feed, pharmaceuticals, asphalt and bitumen, chemicals, and heat utilities, with reference use cases spanning steam generation, thermal oil heating, heated tank storage, dosing and conveying, and heat recovery. Its product portfolio is organized around six core offerings (Energiezentralen, Rohrleitungssysteme, Dosier- und Förderanlagen, Tanklager, Feuerungsanlagen, and Wärmerückgewinnung) plus sub-products such as water treatment, sensor technology, and filter systems, with turnkey delivery from a single source combining its own manufacturing with third-party components from suppliers including Bosch Industriekessel, Gestra, Netzsch, Endress+Hauser, Grundfos, and KSB.

The underlying technology is conventional industrial process engineering: WHG-compliant heated tank farms, H2-ready and biofuel-capable burner systems, stainless steel and copper piping for steam, thermal oil, acids, and food media, and heat recovery via economizers and condensing systems. The company is certified to AwSV standards under TÜV and complies with 44. BImSchV emission rules effective January 2025. There is no software, AI, or digital platform product; the digital posture referenced in company narrative is limited to control systems and sensor integration, not AI/ML.

The business model is project-based, quote-driven, and relationship-led via direct field sales. Revenue is generated through one-time turnkey plant construction projects, hardware supply (notably Bosch boilers), and recurring after-sales service including maintenance, spare parts, and modernization of the installed base. The firm is privately held under Managing Director Dipl.-Ing. Kai Ole Borchers (since 2009), with 11-50 employees, no external institutional investment, no funding history, and no public revenue disclosure. Go-to-market is direct enterprise field sales across Europe with personal consultation, custom engineering, and on-site installation.

Core offering

TEWE GmbH plans, delivers, and installs turnkey process-engineering plants for industrial customers, offering energy centers with steam boiler and thermal oil systems, custom piping networks, automated dosing and conveying systems, WHG-compliant heated tank farms, H2-ready burner/combustion systems, and heat recovery/cooling systems. The company combines in-house manufacturing of piping, apparatus and modules with engineering, installation, commissioning, and after-sales service (maintenance, spare parts, modernization) delivered as single-source projects.

Product overview

TEWE GmbH is a full-service provider of process engineering plants headquartered in Hamburg, Germany. The company's product portfolio centers on six interconnected core offerings: Energiezentralen (energy centers with steam boilers and thermal oil systems), Rohrleitungssysteme (custom pipeline systems for various media), Dosier- und Förderanlagen (automated dosing and pumping systems), Tanklager (WHG-compliant tank farms with sensor technology), Feuerungsanlagen (burner systems including H2-ready options), and Wärmerückgewinnung (heat recovery and cooling systems). Supporting these core products are sub-products including water treatment systems, measurement technologies, and filter systems. The company delivers everything from a single source through planning, manufacturing in its own production facilities, turnkey installation, and after-sales service including maintenance and modernization.

Direct peers

• MAWERA Holzfeuerungsanlagen: German manufacturer of industrial wood-fired and biomass combustion systems, including heat recovery, steam generators, and complete energy plants for industrial customers. Comparable product scope and mid-sized European specialist EPC profile to TEWE.
• Kohlbach Maschinenbau: Austrian manufacturer and EPC of industrial biomass combustion plants, heat recovery systems, and steam/thermal oil boilers for industrial customers. Comparable mid-sized European industrial heat plant EPC to TEWE, with similar vertical customization and turnkey delivery approach.
• Polytechnik Luft- und Feuerungstechnik: Austrian specialist EPC for biomass and industrial combustion plants, planning, manufacturing, and installing turnkey combustion, heat recovery, and steam/thermal oil systems for food, wood, and process industries. Closely comparable turnkey, vertical-specific industrial heat plant model to TEWE, particularly for biomass/biogas-fueled projects.
• Spanner Re² GmbH: German manufacturer and EPC of biomass Combined Heat and Power (CHP) plants and industrial heat/steam systems using wood chips, pellets, and biogas, with full project engineering, installation, and after-sales service. Comparable mid-sized German industrial heat EPC with focus on renewable fuels and H2/biogas-ready combustion, similar to TEWE's industrial energy center focus.
• Herz Feuerungstechnik (Herz Group): Austrian manufacturer and EPC of industrial biomass and solid-fuel combustion plants, boilers, and complete heat/steam systems for industrial customers across Europe. Similar mid-sized specialist EPC model to TEWE, with comparable vertical customization for industrial process heat.
• Wanson Heiztechnik: German industrial boiler and heat recovery manufacturer serving process industries with thermal oil heaters, steam boilers, and waste heat recovery systems across Europe. Closely matches TEWE's thermal oil, steam boiler, and heat recovery product portfolio, but with proprietary OEM equipment rather than EPC integration focus.

Broad incumbents

• Hoval: Liechtenstein-based Hoval designs and manufactures industrial and commercial heating systems including boilers, heat recovery, and complete energy plants, with full EPC and after-sales service capabilities in Germany and across Europe. Direct overlap with TEWE's energy center, burner, and heat recovery offerings, but at much larger scale and with proprietary OEM equipment.
• Bosch Industriekessel (Robert Bosch GmbH): Robert Bosch's industrial boiler division is TEWE's core equipment supplier and also a competitor that sells, services, and integrates industrial steam and thermal oil boiler plants across Europe. Highly comparable product portfolio (steam boilers, heat recovery, controls), but operates at much larger scale and with direct end-customer relationships that can bypass EPCs like TEWE.
• MAN Energy Solutions (MAN Energy Solutions SE): Global manufacturer of large-scale industrial turbines, engines, and CHP/steam systems for power and process industries, including heat recovery and industrial energy plants. Overlaps with TEWE's industrial steam and heat recovery offerings but at vastly larger scale and targeting utility-scale and heavy industrial customers.
• Viessmann Industrial Solutions: Viessmann is a major German heating and industrial systems manufacturer offering industrial boiler plants, heat recovery, and thermal oil systems with engineering, installation, and service across Europe. Comparable product scope to TEWE but at significantly greater scale, broader geographic reach, and with stronger brand recognition.
