Solar Commercial Pump Stations
SOLAR PUMP STATIONS FOR COMMERCIAL AND
INDUSTRIAL APPLICATIONS
A. O. Smith integrated commercial solar pump stations maximize
performance, savings, and serviceability. All-in-one factory assembled
heat transfer station simplifies system design and sizing; saves space
and reduces installation costs. Five pump stations available with single
wall or double wall heat exchangers capable of transferring 160,000 to
800,000 Btu/hr of heat energy captured from the sun. Pump stations
can be combined to supply an unlimited number of collectors.
Designed for commercial and industrial applications including hospitals
and healthcare facilities, government and military buildings, hotels and resorts,
universities, schools and industrial process water.
FEATURES
I Factory assembled fully integrated pump stations – consistent intuitive design.
I Redundant solar and water loop circulation pumps - self-lubricating pumps with
isolation flanges - allows continued pump station operation while servicing
individual pumps.
I Stainless steel (316L) flat plate heat exchangers - single wall or double wall.
I Fully programmable electronic solar control with LCD display that monitors and
records system data with graphical view for temperature, energy and other
operational data.
I Solar control continually monitors system operation and provides alerts for system
errors such as shorted or open temperature sensors, pump failure or loss of flow.
I SD memory card slot on solar control - saves and transfers configuration settings
from one pump station to another - provides permanent storage for energy data.
I Web module for online monitoring via Internet or local intranets.
I Standard energy metering via onboard solar control with factory installed surface mount
temperature sensors - energy data logging, tracks performance and savings.
I Optional MID certified energy meter (part number 9008131005) with well mounted
temperature sensors - certified validation of solar contribution required for Renewable
Energy Credits (RECs), Power Purchase Agreements (PPAs) and other incentives.
I Pulse type electronic flow meter.
I Surface mount temperature sensors in solar and water loop – monitored by solar control
to start/stop circulation pumps and for standard energy metering.
I Temperature sensor wells (4) are provided at solar and water loop connections to heat
exchangers - for optional energy meter or field supplied temperature sensors.
I Fluid balancing valves for precise flow control.
I Full port isolation ball valves at solar and water loop connections.
I Air stripper with automatic air vent - purges air from solar loop.
I Brass body wye strainer in water loop protects pump station components from debris.
I Solar and water loop pressure relief valves.
I Removable access panels on all four sides – allows ease of servicing.
OPTIONAL MID CERTIFIED
