About HANSA Klimasysteme
HANSA Klimasysteme GmbH is a manufacturer and project partner for ventilation and air conditioning technology based in Strücklingen, municipality of Saterland (Lower Saxony). The company designs and manufactures project-specific ventilation and full air-conditioning units (AHUs) with air capacities up to 65,000 m³/h per unit, including the Blue Line product range (full air conditioning with heat recovery), Free Line (heat extraction with free cooling) and Slim Line wall-mounted units. Production is carried out under QM conditions according to DIN EN ISO 9001:2015; components are executed in steel with corrosion protection up to C5-H, stainless steel and aluminium. In addition to hygienic and ATEX versions, HANSA offers in-house measurement and control (MSR), DDC and control cabinet technology, the AI-based control optimisation etaSmart, the remote connectivity solution etaConnect as well as integrated refrigeration and heat pump technology. Fields of application include industry, data centres, healthcare, swimming pools, schools, laboratory and research, museums as well as energy facilities such as CHP units and converter stations. Through the HANSA-etaTECH division, the company supports its systems with on-site maintenance, servicing and commissioning.
