What Hemstedt does

Hemstedt GmbH is a privately-held German specialty manufacturer of electric heating cables, heating mats, and cold-storage technology products, founded in 1974 in Brackenheim and now in its second generation of family ownership. Its catalog spans more than 35 SKUs organized across six application verticals: residential underfloor and climate-neutral heating (GREEN ELECTRIC MAT®, GREEN ACCU MAT®, Dünnbettheizmatten), cold-storage and refrigeration infrastructure (Fahrbetonheizmatten, Rahmenheizung, Tauwasserablaufheizung, control boxes, emergency alarm systems), agricultural and viticulture frost protection (WINE FROST CONTROL, Tränkenheizung, Teichheizung, Stallheizung), sports and public infrastructure (D-COLD Freiflächenheizung for stadium turf, heliports, traffic routes), industrial and hazardous-area heating (SH/GSiSi silicone cables rated from -70°C to +750°C, ATEX-certified trace heating and connection sleeves), and a line of mechanical regulators and thermostats. The technical differentiator is the proprietary HEM-SYSTEM® sleeveless (Muffenlos) transition technology, which enables variable power zones in frame-heating applications without traditional connection sleeves.

The business operates a B2B sales-led model centered on direct customer engagement via dedicated inquiry, order, and general-contact email channels, supplemented by professional trade distribution through heating installers, refrigeration contractors, and industrial equipment suppliers. Revenue is generated almost entirely through hardware sales — finished goods, meterware, and custom-configured cables tailored to project-specific length, power, and certification requirements — with quote-based pricing for non-standard configurations and no public price list. The firm holds ISO 9001:2015 (cert. 12.08.2025), ÖkoPLUS (23.03.2024), CE, and ATEX certifications, and explicitly markets "100% Made in Germany" with fully in-house production.

Named end-customers and use cases include French Ligue 1 football clubs (UEFA-compliant turf heating), vineyard operators (row-by-row frost control), supermarket chains (anti-fog glass heating for freezer cabinets), and butcher-shop display cases. Markets served are concentrated in Europe, with a multilingual (DE/EN) website and social-media presence supporting limited international reach. The firm is actively hiring for production, logistics, and commercial apprenticeship roles, and has registered four proprietary product brands since 2024, indicating ongoing product-surface expansion rather than capital-markets activity — no funding rounds, M&A, or IPO transactions are disclosed.
