Highly efficient variable speed drive reduces energy consumption
Xylem, a global water technology leader, has debuted the 5th generation HYDROVAR, an intelligent control system that accurately adapts to system demands, helping end-users realise cost and energy savings while achieving optimum system performance. The new drive and motor control can reduce energy consumption of a pump by as much as 70 per cent.
Capable of running systems with up to eight pumps, the 5th generation HYDROVAR has multimaster functionality, enabling each individual pump to take control if one or more units or sensors are not active. This continuous booster system operation ensures reliable water pressure across various residential, industrial and commercial applications.
Easy installation and commissioning
The 5th generation HYDROVAR is backward compatible to the current Generation 4 HYDROVAR product and is designed to accommodate both new and retrofit installations. A newly added wiring harness includes a separated wiring chamber with a dedicated cover that provides safe and easy access to the wiring, while protecting the unit’s electronic components. The clip-and-go mounting system further simplifies the direct fitting process.
Set-up and commissioning is also fast and simple. The start-up menu guides users through every step of HYDROVAR’s commissioning process, while the larger LCD display shows an expanded range of system parameters for standard motors. This functionality enables installers to manage a wider range of data, ensuring accurate programming at set-up.
The 5th generation HYDROVAR comes standard with BACnet and Modbus capability for seamless Building Management System (BMS) integration. Optional Wi-Fi for remote connection to the unit via any mobile device, laptop or PC is also available.
Extended system lifecycle, efficient operation and simple retrofitting
Wear and tear caused by standard operation is minimised due to innovative features, including advanced motor control software that extends the life of the equipment by reducing heat. The HYDROVAR also has an embedded Current Total Harmonic Distortion (THDi) filter that lengthens overall life of the equipment connected to the same grid and preventing cables from overheating without the need for reactor filters.
Using HYDROVAR with an existing pump can lead to significant energy savings, especially when operating at partial loads. It can be efficiently retrofitted to any standard asynchronous pump motor suitable for variable speed operation. HYDROVAR’s direct mounting method does not require a special adaptor, and is available for power ranges from 0.55 to 22 kW, making the retrofit process efficient, easy and cost-effective.
In many cases, pump systems are oversized for the application and use more energy than needed for typical operation. The 5th generation HYDROVAR varies motor speed to match system demands, keeping energy and operational costs low. Additionally, the soft start-and-stop functionality adapts pressure according to system requirements, dramatically extending equipment life.
HYDROVAR’s modular design enables a customised fit for any configuration of pumps, and can be motor or wall-mounted for use with any manufacturer’s pump. Configuration options include a range of a single pump to as many as eight pumps to meet any application requirements.
Introduced in 1995, the HYDROVAR variable speed drive has been continually updated, confirming its legacy as the industry’s choice for optimising fixed speed pump efficiency.
