SOS Kaltetechnik

What SOS Kaltetechnik does

SOS Kältetechnik GmbH is a private, Bavaria-based refrigeration, climate control, and beverage dispensing system installer operating as part of the Kälte Eckert Gruppe. The company plans, installs, and services three core product lines: commercial and industrial cold rooms (Kältetechnik) for gastronomy, trade, and industrial customers; air conditioning solutions (Klimatechnik) for private and commercial settings; and professional draft beverage systems (Schankanlagentechnik) for gastropubs, restaurants, canteens, and bars. Its technology stack relies on components sourced from named manufacturers including Mitsubishi Electric, Daikin, Viessmann, Cool Compact, Roma, Schiessl, Frigotechnik, HEFA, Wessamat, and Nordcap, with a stated focus on natural refrigerants and energy-efficient, environmentally friendly solutions.

The company generates revenue through three streams: one-time installation project work, recurring maintenance contracts and emergency service (with after-hours and weekend surcharges), and equipment/component sales. Go-to-market is a direct, project-based B2B sales motion supplemented by a digital presence including Google AdWords and Analytics; pricing is quote-based with no published rate card. Customer segmentation is horizontal across gastronomy (primary), trade and industrial cold storage, and residential climate control. The company is a member of the Allianz bluu unit, a strategic alliance of regional German refrigeration, climate, and ventilation specialists that provides a shared internal academy for employee training and collaborative resource pooling. The company employs 11-50 staff at its headquarters in Königsdorf, Bavaria, is led by Managing Director Florian Selb, and is registered as a private limited company (GmbH) in Munich. Effective May 2026, the company plans to add DIN 6650-6 compliant beverage line cleaning to its regulated service portfolio.
