Gartner, Keil & Co

What Gartner, Keil & Co does

Gartner, Keil & Co. Klima- und Kältetechnik GmbH is a privately held German specialist in HVAC and refrigeration technology, headquartered in Neulußheim, Baden-Württemberg, operating under the legal form of a GmbH (HRB 421233, Registergericht Mannheim). The company designs, installs, maintains, and modernizes climate and refrigeration systems for commercial, industrial, and residential customers in the Rhein-Neckar metropolitan region, with over 30 years of operating history and a certified Fachbetrieb status under the Wasserhaushaltsgesetz (Water Management Act).

The product portfolio spans two main categories. Under Klimatechnik (air conditioning), the company delivers VRV/VRF multi-split climate systems for hotels and commercial buildings, room climate units with high energy efficiency, switch-cabinet and server-room cooling, climate cabinets with humidification, and swimming pool dehumidification. Under Kältetechnik (refrigeration), it delivers compression refrigeration with heat recovery (Verbundkälteanlage mit Wärmerückgewinnung), cold storage for fruits and vegetables, banana ripening chambers with precise temperature progression control, butcher-shop cooling installations, and F-Gas compliance retrofits using modern chemical or natural refrigerants. Technical differentiators center on energy-resource efficiency and domain-specific specialization (e.g., ripening chamber temperature control profiles).

Commercially, Gartner, Keil & Co. operates a sales-led, direct-customer model with no resellers, marketplaces, or self-serve channels. Revenue is generated through three streams: (1) project-based HVAC/refrigeration installation contracts, (2) recurring maintenance and 24/7 emergency service, and (3) consulting on F-Gas compliance and modernization. Pricing is quote-based and not publicly disclosed. The company is part of a regional group that includes aeria Kältetechnik GmbH and is associated with the Kälte Eckert Gruppe via its website footer. In a recent leadership change, Jan Hahn took over as sole managing director alongside his role at aeria Kältetechnik GmbH, with Markus Müller appointed as location manager.
