With the µRack series, CAREL offers a series
of compact and economical parametric controllers that are simple to use and
install, for the complete control of small compressor racks, with the possibility
to manage up to 5 relay outputs for controlling devices such as the compressors
µRack uses a high efficiency LED display to show the values monitored,
and icons representing the status of the devices and the operating modes.
The electrical connections have quick couplings for the fast and safe connection
of the instrument, and cable kits can be created when the controller is installed
on the production line. Using the PWM output, the controller can also manage
the condenser fan speed control. A series of optional modules widens the range
of performance of the instrument, allowing rapid programming using the hardware
key even when the instrument is off, and connection to the supervisory system
for the complete monitoring of the unit.
Compressor racks with floating condensing pressure control can be managed if
the installation (showcase-cold room) is fitted with electronic valves. One
very innovative feature allows the same controller to manage mixed systems of
compressor racks with two refrigerant circuits, a single condenser and two suction
The functions implemented, the dimensions and the simple installation and connection
make these controllers the best solution for the management of compressor racks.
