Variable speed pressure boosting units
Pressure boosting units from SPECK Pumpen are mainly used in drinking water supply when the supply pressure is not sufficient. They ensure a reliable water supply on all stories. Energy consumption has always been the same, regardless of actual water requirements. The Aquacell AE-M variable speed units are now making a sustainable change and saving around 50 % of the energy required by a conventional pressure boosting unit. It is easy to operate and can be monitored remotely via an app.
The new Aquacell AE-M pressure boosting units ensure simple water supply in private households with up to 6 stories at an inlet pressure of at least 0.5 bar. Available in three different sizes, they are optimally designed for one to six-family households with gardens.
The units are supplied ready to plug in, for a power supply via a 230 V socket, for easy installation and commissioning. The Aquacell AE-M adapts to all needs. Parameterisation is not necessary. It can be easily operated and the target pressure adjusted via an LED display with keypad. It is also possible to monitor the unit via bluetooth using an app on the smartphone. Running time, energy consumption, operating mode and error messages can be called up at any time and from any location.
The Aquacell AE-M can be switched on and off automatically by a pressure transmitter located in the end pressure side. The control tank is an 8 l diaphragm pressure vessel mounted in the pressure line. The speed is controlled by a frequency converter mounted on the motor. The pressure boosting units are equipped with a dry run protection which automatically switches the unit off in the event of water shortage.
While conventional pressure boosting units operate continuously at the same speed to maintain the required pressure, the Aquacell AE-M's frequency converter adjusts the speed of the pump motor to the actual water requirement. Measured in terms of the average water consumption of a detached or two-family house, energy consumption is reduced by up to 50 % in comparison.
