HEBER

What HEBER does

Heber GmbH is a privately held, family-owned German manufacturer of ventilation and air conditioning equipment headquartered in Rotthalmünster/Weihmörting, Lower Bavaria. The company's legal entity was founded in 1979 by Alfred Heber and traces its industrial lineage to a 1927 machinery works; it is currently led by third-generation family members Günther Heber and Joachim Heber. All products are manufactured at a single Rotthalmünster site, with 51–100 employees.

The product portfolio is organized into five lines: Rahmengeräte (indoor frame units in 30/50 mm variants, including a hygienic RG 50 HYG variant), Dachzentralen (outdoor rooftop units with cold-roof galvanized construction and polyurethane or mineral-wool insulation), Hygiene/Reinraum (DIN 1946-4, VDI 6022, EN 1886, EN 13053 certified units for healthcare, pharmaceutical, and laboratory applications), Trocknungsanlagen (drying systems that recover waste heat from biogas plants for wood-chip, grain, hay, and straw drying), and Sondergeräte (custom-engineered units for non-standard dimensions, oil-separation exhaust up to 4,000 Pa, and process air drying rotors at 90–130°C). The technical differentiator is a proprietary frame construction using galvanized, insulated hollow profiles with aluminum die-cast corners, producing TÜV-measured deflection of 0.6 mm/m versus the 4.0 mm/m allowed under the highest EN 1886 Class D1 rating.

Heber sells exclusively through a B2B direct sales motion in Germany, with regional field offices covering Nordbayern, Südbayern, and Baden-Württemberg, supplemented by an external specialist (Kraus & Harrer GbR) for process air and painting systems in Baden-Württemberg. Pricing is project-based and not publicly disclosed, with multi-year contracts typical of engineered industrial HVAC deployments. End customers span automotive and supplier industry, electronics, chemicals, commercial offices, hospitals, pharmaceuticals, and agricultural/biogas operations. Revenue is not publicly reported; the company holds ISO 9001:2015 and ISO 14001:2015 certifications and is described in its own materials as one of the leading German manufacturers of ventilation and climate equipment.

Core offering

Heber GmbH manufactures ventilation and air conditioning equipment at its facility in Rotthalmünster, Bavaria. The product portfolio spans four core lines — frame units (Rahmengeräte), rooftop units (Dachzentralen), hygienic/cleanroom units, and drying systems for biogas synergies — plus bespoke custom units (Sondergeräte) built to specification. Equipment is sold to industrial, healthcare, pharmaceutical, agricultural, and commercial building customers across Germany.

Product overview

HEBER GmbH offers a comprehensive portfolio of ventilation and air conditioning equipment manufactured in Rotthalmünster/Weihmörting, Bavaria. The product portfolio centers on four core product lines: (1) Rahmengeräte (frame units) — indoor units built with galvanized hollow frame profiles and aluminum die-cast corners, available in INDOOR RG 30, INDOOR RG 50, INDOOR RG 50 TE (thermally decoupled), and INDOOR RG 50 HYG (hygienic) variants with 30-60mm wall thicknesses; (2) Dachzentralen (rooftop units) — outdoor units including OUTDOOR RG 50, OUTDOOR RG 50 TE, OUTDOOR PAN 60 PU, and OUTDOOR PAN 60 MIN designed for weather resistance with cold roof construction; (3) Trocknungsanlagen (drying systems) — waste-heat recovery systems for biogas plant synergies supporting wood chip, grain, and hay/straw drying applications; and (4) Sondergeräte (custom units) — bespoke climate equipment engineered to customer specifications including oversized formats, oil-separation exhaust units, and process air dryers. The modular construction philosophy enables tailored solutions across industries including automotive, pharmaceuticals, healthcare, and agriculture.
