Laing Thermotech Introduces the Revolutionary New D5
Ecocirc Solar Pump at the Solar Power 2006 Trade Show Oct
16-20
The first DC spherical motor pump
for direct connection to solar panels with automatic
performance optimization using maximum power point tracking
technology.
Chula Vista, CA (PRWEB) October 13,
2006 -- Laing Thermotech Inc. recently introduced the
exciting new D5 Ecocirc Solar pump, the first pump designed
to work directly with the power supplied by solar panels.
"Laing’s D5 Solar pump only consumes as
much energy as needed and will perform a soft start with as
little as 1 watt of power " said Laing’s CEO, Scott S.
Shimer.
The Ecocirc Solar pump can be used
wherever a highly efficient circulation pump is needed
without a direct connection to AC power. It can be connected
directly to a solar panel and is characterized by its small
size, high efficiency, very low power consumption and its
MPP tracking. The shaft-less spherical motor technology
enables a long, maintenance-free and quiet service life.
Areas of application are thermal solar systems for single
family homes.
The principle of the spherical motor,
which was invented by Laing, is fundamentally different from
conventional canned motor pumps. The only moving part in a
spherical motor is a hemispherical rotor/impeller unit,
which sits on an ultra-hard, wear-resistant ceramic ball.
There are no conventional shaft bearings or seals. This
rules out, the possibility of play in the bearings and the
increase in noise associated with it. These pumps are
particularly robust and provide exceptionally long service.
The self-realigning bearing is lubricated and cooled by the
media. Maintenance is not necessary under normal conditions
and even after lengthy shutdown periods, a reliable start-up
is virtually guaranteed. The parts exposed to the fluid are
completely corrosion resistant.
The D5 Solar pump has been programmed
for a soft start-up. When the solar panel provides
sufficient power, the pump first goes through the alignment
phase, turning the rotor into the position required for
start-up. Then the processor waits until the built-in
capacitor has recharged sufficiently. This enables a
start-up with minimal power. Cycling due to unsuccessful
starting attempts is minimized. Even after prolonged
shutdown, the pump will start reliably. The D5 Solar pumps
are the first and only spherical motor pumps with
self-optimizing software. Every three seconds, the processor
will modify its operating point on the voltage-current curve
of the PV panel to find the point of maximum performance.
This is called the "Maximum Power Point" (MPP.
At this point, the pump achieves the
maximum rpm and therefore the maximum performance. There is
no need for a separate performance adaptation, the pump will
always find its best operating point under any given light
and temperature conditions by itself.
Laing is a leader in hot water
circulation technology, offering a full line of
low-energy-consumption, fractional-horsepower pumps for
residential and industrial use. For more information about
