General
The efficiency of regenerative heat exchangers can be adjusted
by means of the rotor speed.
The rotor speed can be adjusted by means of the KR controller
across the complete control range. For further performance
features see page 4.
The new KR controller is the fourth generation of a series of
controllers for regulating regenerative heat exchangers
developed by our company since 1979. Developments in
modern processing technology and our wish to make the
operating controls as simple as possible provided the impetus
for an extensive development programme.
Only two types are required for all rotor sizes:
KR4 = 400 Watt
rotor diameters smaller than 3760 mm
KR7 = 750 Watt
rotor diameters larger than 3760 mm
The KR controllers represent the latest standards for rotor
technology.
The controller is housed in an extruded aluminium case which
improves heat dissipation and increases mechanical stability.
The case also ensures good electric screening. More space
was provided for the wiring and the new configuration of the
terminals makes it easier to hook up the controller.
And of course all new industry standards have been taken into
account. The radio shielding incorporates the latest technology.
The rotor drive is effected through three-phase alternating
current motors which can be operated up to a rotor diameter of
1919 mm direct from the mains. Furthermore, an acceleration
and deceleration ramp must be utilised for the gears.
So, for the optimum control of the drive, the rotor controller KR
is required.
