Offering apparent energy savings of up to 70 per cent, water technology provider Xylem has launched its Hydrovar 5th Generation variable speed pump drive offering “a wealth of new features and new additions to the range”.
Said to be known for its robust and quality design, Hydrovar is now available across 21 models ranging from 1.5kW, 1 phase to 22kW, 3 phase – ensuring there is an option for every application, says the firm. New features include a separate wiring compartment, with a dedicated cover to protect wiring components. And the electronic power component is potted, meaning that there is increased thermal dissipation and robust protection against vibration and condensation issues with the ability to operate down to an ambient temperature of -10oC.
For efficiency the Hydrovar 5th generation is described as “best in class” and “when connected with a Lowara IE3 motor, the system can achieve the highest IES class – IES2”. The firm describes this as ground-breaking efficiency enabling customers to achieve energy savings of around 70 per cent, when compared to a fixed speed pump.
There are two clamping kits across the three mechanical sizes. Motor clamps are also now designed with strap-like links, “which can easily be snapped off for the perfect fit”. A larger LCD display shows an expanded range of system parameters, making it easier to commission and operate, says the firm. Included in the backlit display is a quick start-up menu for faster set-up, featuring a pre-programmed parameter for standard motors. Users also have the option to select a ‘self-learning capacity’ feature which enables installers to quite literally install and go, with no requirement for programming, even on non-Lowara products.
Hydrovar is motor or wall mountable, via “a simple process which allows you to ‘clip and work’ onto any standard AC motor”.
In addition, the range is now compliant with the latest Harmonic Distortion legislation, reducing contaminating signals and therefore wave discrepancies. Furthermore the Hydrovar now features a protective screen to reduce Electro Magnetic Compatibility (EMC) interference.
Specifiers can choose between the standard Modbus or Bacnet versions, and there is now also the option to be Wifi enabled. Software Thermal Control (STC) is built-in and will detect if the Hydrovar is too hot or if the motor is overloaded, enabling the operator to act quickly – ensuring the extended life of the motor. This built-in software protection has eliminated the need for a separate motor PTC.
Mark Trevaskis, Sales Support Manager at Xylem, commented: “Hydrovar 5th generation is more than a few simple additions. We have carefully assessed how people use it and how we can improve the range to make it simpler to use, install and to make it even more efficient. With an extended range and advanced motor control, the new and improved variable speed pump drive can be used across a whole new selection of high-level installations, bringing efficiency and functionality in its wake.”
