Calpeda Easymat 9,2 MT Variable Speed Control Unit

 Variable speed system driven by frequency converter, for the pressure control in domestic and residential plants. The system is connected to the delivery pipe providing for simple installation and better cooling (patented) making the unit more compact and easy to assemble. Easymat is supplied with one pressure transducer, G 1/4 connection and 1.5 m cable length.

Single phase supply 230V, with three phase motor 230V.

Applications

Automatic frequency inverter control for use on pumps to increase network pressure. The system maintains constant pressure whilst the controlling the pump operation against changing system demand.

For protection of the pumps:

– Against dry running

– Against operations with closed connection ports

– Against overcurrent of the motor

– Against overvoltage and undervoltage of the power supply.

Features

Constant pressure

The Easymat via a frequency inverter keeps the pressure constant as the flow demand changes.

Energy saving

The variable speed operation ensures that only the energy required by the plant at any instant is used.

System reliability

Because the easymat is independent of the pumped liquid it's operation is not affected by fluid impurity. A float switch can also be integrated to further protect against dry running.

Flexibility

Thanks to it's patented design the easymat does not come into contact with the pumped fluid. This provides for more flexibility during installation eliminating the need for pipe-work modifications or the installation of isolating valves.

Easy to use

The easymat has a clear display making it very simple to set-up.

Cascade control mode

The system flexibility allows via a microprocessor for cascade operation of two easymat's via one pressure transducer.
