Heritage EC Series – CHDEC50DD
Performance Curve - CHDEC50DD
Description
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.
Features - 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°
ConstructionRobust, 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
Motors
Type - electronic commutated (EC) motor.
Electricity supply - 200-277V single-phase 50/60Hz
and 380-480V three-phase 50/60Hz.
