About altAIRnative
altAIRnative GmbH develops and manufactures its own modular compressed-air combined heat and power units (DHKW) that simultaneously provide compressed air and heat at high temperature levels for industrial customers. The systems are manufactured in-house and offered in capacity sizes tailored to industrial requirements; compressed air generation is optionally oil-lubricated or oil-free (Class 0). In addition to in-house manufacturing, the company integrates the DHKW components as part of holistic system solutions: planning, construction, implementation and integration into existing or newly created compressed-air, heat or refrigeration networks are provided from a single source. The service portfolio comprises feasibility and demand analysis, design, installation, full-service support as well as assistance with applying for funding. Additionally, the GmbH offers compressed-air technology, CHP systems and energy efficiency measures. Proven fields of application include, among others, the food industry and electroplating. In research and development, the company works together with IAB Weimar on a thermally driven sorption drying of compressed air intended to replace electrically driven refrigeration dryers.
