The Winston Series CPC

The Winston Series CPC

The WINSTON SERIES CPC incorporates a geometrical concept, uses selective crystal
plating techniques and special anti reflective coatings to achieve high-energy efficiency
levels. The WINSTON SERIES CPC has a solid structure that provides excellent support for
its outer glass covering; its rigid design provides safety and reliability, even under harsh
winter conditions. With its mirrors reflecting the solar radiation onto the fluid tubes or
receivers, the WINSTON SERIES CPC has a cooler surface than conventional flat collectors.
The WINSTON SERIES CPC delivers more energy per square meter than competing solar
collectors and does so at unit prices that can facilitate cost effective applications for both
distributors and end users.
Applications:
- Domestic and Commercial water heating (Also as thermosiphonic system).
- Domestic space heating (Easily combined with existing systems).
- Air conditioning (in connection with single stage absorption machines).
- Swimming Pool and Spa Heating
- Possible building integrated utilization as a leak- proof roof due to its uniform structure.

Reliability of the Winston Series CPC Collector
1. Leakage through glass sealing into the housing.
The silicon-seal on each side of the glass ensures a reliable water proof seal.
2. Leakage from the flow tubes/ brazing.
Controlled process and individual testing of each collector (in pressure of 12 Bar/ 168
PSI) ensure efficient and problem- free sealing.
3. Selective coating of the flow tubes.
The electro-plate crystals of selective coating- and the semi-selective painted coatings are
stable and do not change its properties (quality) after many years of operation.
4. Anti- reflective coating of cover plate.
Special process ensures stability of the coating for many years.
5. Insulation.
The polyurethane insulation retains its performance for many years specifically due to the
low temperature that develops in the collector housing as a result of the CPC design.
Instructions for System Design
The system designer for the WINSTON SERIES CPC must observe the following:
1. Regulating the flow rate
For optimal performance use a control valve for each series of panels to ensure equal flow
rate. This requires special attention when a different number of panels are used in each
series of panels or all panels are not mounted on an equal level. To regulate the flow rate
through every collector in a panel, set the suitable flow rate.
2. Use an automatic air release valve (with rapid exhausting mechanism) and a safety
valve at the outlet of each series of panels.
3. Drain back option (freezing & over heating)
For the heat transfer liquid draining system, use a manifold construction that will allow the
heat transfer liquid to be completely drained from the collector. To ensure complete
draining of each series of panel, the collector array should be tilted and sloped at least ¼􀂴
per foot of collector. No air vents required.
4. If the CPC collector is used in an indirect or closed system, additives such as propylene
glycol should be used to avoid corrosion of any dissimilar metals in the solar loop/piping
and freeze protection.
5. Vertical positioning
For vertical positioning, the system should be operated with circulating pump of sufficient
size to force any trapped air out of the collector and maintain the recommended flow rate.

Instructions for Handling
General Instructions
1. Whenever handling the collector, be sure to wear gloves and clothes that fully protect
your skin.
2. Do not lift and handle the collector holding the inlet and outlet connection.
3. Do not scratch the glass panel.
4. The collectors should be stored in a place where they will not be exposed to direct
sunlight, rain, or snow.
Instructions for Collector Assembly
1. During assembly, take special care not to drop heavy tools on the glass panel.
2. For securing a collector, be sure to use rubber gaskets or other appropriate cushioning
material.
Instructions for Installation
1. Install the panels on the roof; protect the glass panel with cardboard or other material.
Take special care not to damage or deform the collector. The installers on the roof should
use safety belts to prevent injury or damage.
2. Installing the panels on its stand / construction should be perform using the standard flush
mounting, or tilt mount hardware. Direct mounting to Uni-Strut is recommended (see
drawings on pages 13 & 14).
3. When handling the panel do not pull or push the enclosures, inlet and outlet tubes.
4. Do not release the safety belts until the panel is fixed on its stand.
5. Do not remove the special protective cover from the collector until the water system is
full and ready for operation.
6. Do not touch the inlet & outlet with bare hands. They may be extremely hot due to heat
absorption.
7. To prevent possible corrosion or reduced structural strength, do not locate the system in
the following places:
One) In the vicinity of a cooling tower
