R…G – EC-Tube Fans
Construction of steel
- easy installation in any position
- easy electrical connection via terminal box
- energy saving with EC-motors
- motor protection by thermal contacts
- isolation class F
The impellers are balanced together with the external rotor motors at two levels according to quality level
G2.5/G 6.3 DIN ISO 21940-11. Backward curved centrifugal impeller made of plastic.
Motor and Motor Protection:
EC external rotor motors according to DIN EN 60034-5 are used, ball bearing mounted and with integrated
thermal contact for motor protection.
The sleeplessly controllable EC motors are characterized by a very high degree of
efficiency, even in the partial load range, as well as good control and regulation
behavior. They are easy to connect, individually preconfigured, compact in design
and demonstrate a high power density. The implementation of additional functions
(e.g. volume flow and pressure control) is possible. All motors can be speed
controlled in the range 0-100 %.
The motor protection is integrated. All necessary parameters such as temperature,
blocked rotor, over- and undervoltage and power are continuously checked and
monitored via intelligent fault management.
