Spanner Re²

What Spanner Re² does

Spanner Re² GmbH is a German manufacturer of decentralized biomass gasification combined heat and power (CHP) systems and pellet heating equipment, headquartered in Neufahrn in Lower Bavaria. Founded in 2004 and operating with 51-100 employees, the company designs and builds modular Holz-Kraft-Anlagen (HKA 35 through HKA 700, scalable into multi-MW configurations) that convert wood chips, pellets, waste wood, agricultural residues (including macadamia shells and kernels), and industrial byproducts into synthesis gas via proprietary pyrolysis-based wood gasification; the syngas is then used in integrated CHP units for simultaneous electricity and heat, or directly burned in industrial thermal processes as a natural-gas substitute at temperatures above 1,000°C. The company complements this industrial line with Re² Pelletheizungen (4-100 kW thermal) developed from the 2016 HAPERO brand acquisition, and a webshop for spare parts, retrofits, and refurbished systems priced roughly 30% below new units.

The commercial model is primarily direct enterprise sales of high-value, quote-based hardware (40/60 payment terms) targeting sawmills, agriculture (farms, dairies, cooperatives), municipalities, hotels and wellness facilities, logistics operations, and energy-intensive industrial buyers including brick, metal, and food processors. Distribution combines a field sales team with relationship-driven demand generation through 'Energietage' (Energy Days) on-site demonstrations, IFAT trade fair participation, and a content/news footprint across the website, YouTube, and social channels; recurring revenue is supported by spare-parts supply, power-class engine upgrades using AGCO-Power systems, energy delivery contracting, and a refurbishment trade-in program. With 1,000-1,100+ plants operating globally across Germany, Austria, Switzerland, Slovenia, the Netherlands, Poland, the UK, Congo, Japan, and New Zealand, recent strategic priorities have shifted toward industrial process-heat decarbonization and multi-MW projects, exemplified by 2025-2026 partnerships with 2G Energy AG and Charwood Energy Group and a March 2025 product launch of the HKA Pellet gasifier.

Core offering

Spanner Re² GmbH manufactures and sells decentralized biomass gasification combined heat and power (CHP) systems (Holz-Kraft-Anlagen, 35 kW to multi-MW) that convert wood chips, pellets, and waste biomass into electricity, heat, and synthesis gas via a proprietary pyrolysis process. The company also produces Re² pellet heating boilers (4-100 kW thermal) for residential and commercial heating, along with peripherals such as fuel dryers, containerized EnergyBlock solutions, and refurbishment/upgrade services.

Product overview

Spanner Re² offers two main product lines: (1) Holz-Kraft-Anlagen (biomass power plants/CHP systems) ranging from 35 kW to multiple MW, which convert wood chips, pellets, and other biomass/waste materials into electricity, heat, and syngas through wood gasification; and (2) Re² Pelletheizungen (pellet heating systems) ranging from 4 to 100 kW thermal for residential and commercial heating. The product portfolio includes modular CHP units (HKA 35, HKA 50, HKA 70, HKA 70 Prozess, HKA 300, HKA 300 PRO, HKA 700), pellet heating boilers (10/15/25/35 kW with cascade capability up to 100 kW), wood chip dryers, and supporting peripherals. The company also offers refurbishment services, power class upgrades using AGCO-Power engines, and energy delivery contracting.
