The parent company, Rosenberg Ventilatoren GmbH, was established 1981 in Künzelsau and is a major supplier of fans, motors and air conditioning units in the international market. Ecofit and ETRI are wholly-owned by Rosenberg, and their products compliment the Rosenberg line.
Ecofit was established in 1976 as a manufacturer of induction motors and fans. By 1981, it had developed its own range of external rotor motors and integrated them with motorized impellers, a concept that formed the platform for its growth and success.
ETRI was founded in 1945 and has been active in the U.S. since 1976. The ETRI product line comprises low-cost fans for a vast range of cooling applications and high-technology fans for railway, marine, military and aircraft applications.
Rosenberg USA's Charlotte-area warehouse stocks a wide selection of Rosenberg, Ecofit and ETRI products for immediate shipment, plus a full line of accessory products and controls. Custom fan and motor development is also available to fulfill particular requirements. The Rosenberg USA staff provides technical expertise and application engineering as well as outstanding customer service.
