What NOVA Apparate GmbH does

NOVA Apparate GmbH, founded in 1951 in Donaueschingen, Baden-Württemberg, manufactures custom-engineered central room air conditioning units (RLT-Geräte / raumlufttechnische Komplettsysteme) for commercial and industrial buildings across Europe. The company's core offering is a freely planned (freigeplante) Vollklimaanlage individually engineered to project specifications, covering single-room ventilation in hotels and offices, production-hall climate control, and full HVAC for complex real estate portfolios. Its proprietary technology stack includes Ka2O regenerative indirect evaporative cooling, plate heat exchangers achieving up to 93% heat recovery, EC fans, and the KaControl building automation system; complementary products span air diffusers (KaMAX), unit heaters (TOP), door air curtains (Tandem), fan coils/KaDeck ceiling cassettes, and the WZA decentralized school ventilation unit. Digital planning tools include BIM data sets and the KaData online sizing tool for the standardized KaCompact KG product line.

The business operates as a B2B project-based manufacturer with no public pricing, selling through a nationwide field sales network supported by external project managers and the broader Kampmann Group's 11 European and North American locations. End customers include engineering firms and architects (specifiers), building contractors and installers (channels), and building owners, property managers, and operators (end buyers) across verticals including manufacturing, hospitality, retail, education, healthcare, and leisure. Revenue is generated primarily from one-time capital equipment sales of custom RLT units, with supplementary income from standardized components, maintenance and inspection services, spare parts, and the Kampmann Kampus training program. NOVA is a wholly-owned subsidiary of family-owned Kampmann Group GmbH (1,100+ employees globally) and has been fully integrated into the group as of 2025. Certifications include ISO 9001, VDI 6022 hygiene, VDI 3803, DIN 1946-4 for hospital/cleanroom applications, and ErP directive compliance.

Core offering

NOVA Apparate GmbH manufactures custom-engineered central air handling units (RLT-Geräte) and standardized compact ventilation units (KaCompact KG) for ventilation, heating, cooling, and humidity control in commercial, industrial, hospitality, retail, education, and healthcare buildings. The company also supplies complementary components such as unit heaters, fan coils, door air curtains, air diffusers, school ventilation units, and the KaControl building automation system, supported by professional services including maintenance, spare parts, and technical training.

Product overview

NOVA Apparate GmbH manufactures room air conditioning complete systems (raumlufttechnische Komplettsysteme) as part of the Kampmann Group. The core product is the NOVA RLT-Gerät — a freely planned, project-specific Vollklimaanlage (full climate unit) serving single-room ventilation in hotels and offices, commercial and production ventilation, and full HVAC for complex buildings. It is offered alongside the KaCompact KG, a standardized compact ventilation unit with heat recovery for faster configuration at standard requirements. The portfolio includes complementary decentralized components — Lufterhitzer TOP, Fan Coils/KaDeck, Tandem Türluftschleier, KaMAX Luftdurchlässe, and WZA Schullüftungsgeräte — all managed through the Kampmann KaControl building automation system. Key technologies include Ka2O regenerative indirect evaporative cooling. NOVA also provides digital planning tools including BIM data sets and the KaData online sizing tool.
