AHUs by Rox – Efficient ventilation units for the perfect indoor climate
An air handling unit (AHU) ensures controlled supply and exhaust air management in buildings and processes – efficiently, reliably, and demand-driven. At Rox-Klimatechnik, we design and manufacture modular AHUs that are precisely tailored to the specific requirements of a wide range of industries and applications: from comfort ventilation in offices and schools, to hygiene-sensitive environments such as hospitals or operating rooms, to specialized industrial solutions with high pressure demands or integrated process heat. Our AHUs can be individually equipped with additional modules – such as integrated heat pumps, connected refrigeration systems, high-performance heat recovery units, or intelligent building automation (BMS) for control, monitoring, and optimization of air quality. All components are technically coordinated, energy-efficient, and designed for easy maintenance. Thanks to flexible configurations – from compact units for suspended ceilings to large modular systems – we offer the right solution for every spatial and functional requirement. Whether for indoor or outdoor installation, with hygienic design in accordance with VDI 6022, or with specific requirements for sound insulation, fire protection, or frost protection: Rox AHUs stand for quality, adaptability, and future-proof technology.
