Who we are

Betriebsleiter Herr Sedlmair

Dear business partners and customers,

Lm-therm Elektrotechnik AG has been ensuring an optimum climate in control cabinets, automatic machines, systems and drives both indoors and outdoors since 1961. Our air conditioning and ventilation systems reliably prevent the condensation of valuable electronics. As a long-standing expert in the field of industrial air conditioning, we offer you the necessary components from a single source. We also have expertise in processing individual cable types. In addition to the wide range of products, component assembly is also one of Lm-therm’s areas of expertise. We manufacture our high-quality individual heaters and cable products in our own production facility in Aldersbach. We always focus on high quality standards and fast, customer-oriented delivery.
