Heritage EC Series – CHEEC31DD

The ECOtronic Heritage Series of vertical exhaust roof units has been designed for use in ducted exhaust applications. It combines a high-performance centrifugal fan with an IE6* rated electronically Commutated (EC) shaft motor that delivers ultra-energy efficient operation with the benefit of in-built variable speed control.

Available in 6 sizes ranging from 315 to 560mm diameter

* Future IE6 level of efficiency, considering 20% less losses than IE5 according to IEC TS 60034-30-2 for variable speed electric motors.

• EC motor features reverse polarity protection, locked rotor protection and soft start
• Can be run as an independent ventilation source or integrated into most building management systems
• Windband can be easily removed to allow easy access for cleaning and maintenance
• Can be remote speed controlled with either a 2-10V, 4-20mA, or frequency duty cycle 10-95% (80Hz, 10-24Vpk)
• Can be manually speed controlled by pressing 2 internal motor buttons
• ECOtronic fans are not designed for hazardous or high temperature conditions
• Maximum operating speed can be limited
• Motor is mounted out of the airstream
• Can be mounted at angles up to 15°

Robust, yet lightweight galvanised steel construction.

Impellers are a backward-curved centrifugal design

Windband is fitted with quick-release toggle clamps to facilitate cleaning and maintenance.

Stainless steel construction is an optional extra
