ERI's Largest Energy Recovery Device Seamlessly Integrates into any SWRO Plant's Infrastructure; Reduces Energy Consumption by up to 60 Percent
SAN LEANDRO, Calif.--(BUSINESS WIRE)--Jul. 30, 2009--
Recovery, Inc. (NASDAQ: ERII), a leader in the design and
development of energy recovery devices for desalination, today
introduced the PX-300 device to the company’s portfolio of PX Pressure
Exchanger® (PX) technology. The PX-300 device is the highest-capacity
energy recovery device offered by ERI. Designed to reduce energy usage
and related costs, this new device handles flow rates of 300 gallons per
minute (68 m3/hour) per device. The modular, standardized
design allows the PX-300 to be used in the world’s largest desalination
ERI’s PX devices improve the energy efficiency of seawater reverse
osmosis (SWRO) by up to 60 percent, making desalination a cost-effective
solution for clean water supply. PX devices also reduce the carbon
footprint of desalination, saving more than 700 MW of energy and
reducing CO2 emissions by more than 2.3 million tons per year
worldwide. More than 6,700 PX devices are currently deployed or under
contract to be installed at desalination plants across the globe.
“As SWRO desalination continues to gain global acceptance to address
worldwide water shortages, continuous technology advances are required
to meet energy efficiency and plant reliability requirements,” said Dr.
Richard Stover, chief technical officer at ERI. “ERI is leading a global
effort to make seawater desalination affordable. Our energy recovery
devices are the established market leaders, driven by our engineering,
manufacturing expertise and dedication to meeting customer demand. The
PX-300 device represents the latest in innovation while maintaining the
high performance, elegant design and ease of implementation consistent
in all of our products.”
Built on the same engineering principles as ERI’s standard PX product
family—including the PX-220 and the PX-260—the PX-300 device delivers a
highly efficient, scalable solution for mid-size and large desalination
plants that need premium performance in a larger device. In addition,
the PX-300 device features the latest side-port housing technology to
provide better unit performance and enhanced corrosion resistance. The
PX-300 enhances ERI’s leading portfolio of energy recovery products.
Unmatched Performance—The PX-300 device operates at up to 98
percent efficiency and its performance will not decrease over time.
The new product also achieves a significant reduction in mixing
compared to the PX-220 and PX-260 devices, enhancing desalination
system performance and improving efficiency by reducing membrane feed
Smooth Startup and Operation—Like all of ERI’s PX devices, the
PX-300 operates without the pulsations and water hammer caused by
competing isobaric energy recovery devices. These pulsations have been
known to complicate and delay plant startups and may damage plant
structures, compromise peripheral desalination equipment and/or
adversely affect plant safety. In contrast, hundreds of SWRO plants
around the world have started up with PX technology without delays or
pulsation-related equipment performance problems.
Minimal Footprint—The overall footprint associated with
installing a PX-300 device is six times smaller than competing
isobaric-device installations, saving valuable plant floor space. The
PX-300 unit also weighs just over 80 kilograms and does not require
any special foundation or other support structure, helping to minimize
the overall footprint and installation cost of a desalination plant.
Virtually Maintenance Free—The PX-300 device, like all of ERI’s
solutions, has just one moving part and requires no electricity or
direct control system. PX rotors float on hydrodynamic bearings that
do not exhibit wear over long device lives. With wrought metal ports,
the PX-300 device provides optimal corrosion resistance. This simple
yet elegant design requires no periodic maintenance, making the PX-300
device constantly available and reducing costly system downtime.
Highly Scalable Design—Like all of ERI’s PX models, the PX-300
device offers a unique modular design that can scale quickly,
efficiently and cost-effectively. Unlike competing solutions, PX
devices are standard models that require no customization and can be
installed in any orientation. This plug-and-play system is ideal for
new construction as well as for retrofitting or expanding existing
