Wilo, one of the
leading manufacturers of pumps and pump systems for heating, cooling and
air-conditioning technology, has introduced the “CC-HVAC” series, an especially
comfortable control device for uncontrolled glandless and glanded pumps in
heating, air-conditioning and ventilation systems.
 With the newly developed switchgear and control
device up to six pumps can be controlled automatically at a maximum power of
200 kW. More than eight pumps and larger nominal motor power are possible upon
request. The pump operation can be adjusted exactly to the respective
installation with the standard control functions available in the control
device. The core of the “Wilo-CC-HVAC” is a system controller programmed by
Wilo which takes over the fully automatic control of pump installations. This
controller adjusts uncontrolled pumps in single-pump and multi-pump systems to
the alternating loads. Due to this operating mode according to the
requirements, considerable energy savings can be achieved.
The “Wilo-CC-HVAC” is optionally available with or
without frequency converter. In the version with the frequency converter the
speed of the base-load pump can be controlled stagelessly. Without a frequency
converter the pumps are, for example, switched on or off in the cascade mode
depending on the load. By means of optionally available modules, e. g. for LON,
Modbus or Ethernet TCP/IP, the “Wilo-CC-HVAC” can also be integrated into
building automation. According to the company’s press release, a prototype of
the “Wilo-CC-HVAC” has been adjusting the pump speed exactly to the demand of
the cold system in the cellar of the Culture Palace in Dresden, Germany, for
two years. |
