Butler Sun Solutions Inc. (BSSI), a Solana Beach, Calif.-based manufacturer of solar water heating systems, says it has been issued a patent for its Self-Pressurizing Overtemperature Capsule (SPOC) unit, which automatically protects the system from overheating in solar thermal collector stagnation conditions.
The standard size for the unit is the SPOC-47, which is included in BSSI's complete domestic solar water heating system kits for do-it-yourself or contractor installations. Customized sizes may be ordered for large domestic or commercial systems as well.
