Ecofit was established in 1976 to design, manufacture and sell induction motors and fans. By 1981 it had developed external rotor motors and integrated them with fan impellers, a concept that formed the platform for 35 years of growth and success.
In 1994 ECOFIT is becoming part of ROSENBERG Group, a company with technically similar fan products but designed for larger applications.
By 1998 ECOFIT had taken the decision to cease manufacture of conventional motors and to focus its attention on the compact dimensioned and speed controllable external rotor motor, mainly for fan drive and liquid agitation. |
Etri has long been a leader in the design of air-moving devices, from large industrial fans to miniature flat axial fans.
Established in 1945, previously manufacturing mine ventilation, today ETRI's AC air movers are cooling and protecting the most sophisticated of electronic packages, and our basic commitment to uncompromising quality and high performance standards continues.
ETRI's DC fans offer the design engineer a wide range of design options to meet your specific application need. Various voltages, speeds, bearing systems, and termination configurations provide the engineer the ability to select the performance needed. |
