Product Description
The compact ETECH pressurization system designed for water supply in domestic applications. The integrated SPEEDMATIC speed controller allows the pressurization system to maintain a constant pressure in the installation. A pressure sensor (transducer), which monitors changes in water consumption, alerts the frequency inverter to change the engine speed, thus adapting operation to the new consumption state. The pressurization system is easy to install. Once installed, simply plug the unit into an outlet and the system is operational.
The compact and silent pressure group. It is ideal for domestic installations or small residential buildings to supply water at constant pressure. This group is equipped with a SPEEDMATIC frequency converter with the aim of maintaining constant pressure. This system, in addition to reducing energy consumption, increases the durability of the electric pump, as its mechanics are not always subjected to maximum speed and do not produce water hammer effects as the starts and stops are progressive.
Operation
It is an Inverter system known as a frequency inverter, it is a more technologically advanced device that maintains the programmed pressure (up to the pump limit) unchanged regardless of the flow consumed.
Power Voltage: single phase, 3~400V
Fluid: Clean waters and non-aggressive or viscous liquids, free of solid substances.
Maximum fluid temperature: 45 ºC
Maximum suction height: 7 m
Construction features
Centrifugal pumps specially designed for increasing pressure in domestic water installations. All components in contact with water are made of AISI 304 and are designed for applications in supply, irrigation, cooling and heating systems.
Pump Body: AISI 304 Stainless Steel
Impeller: AISI 304 Stainless Steel
Motor shaft: AISI 304 stainless steel
Mechanical seal: Ceramic/Graphite
Frequency converter
Speed variator for electric pump management; ART ( automatic reset test ) function, when the device turns off due to lack of water, the ART makes several programmed restart attempts until the water is restored; Automatic reset system after a power failure; Internal pressure transducer with digital indication; Current intensity sensor with instantaneous digital indicator; Control panel and 2-digit display; Operational control record, operating hours information, start-up counter; Alarm log.
