<p>A freeze protection system for a car wash facility having a plurality of bays an d having exposed water lines located in an area that is subjected to freezing temp eratures. By using a temperature probe connected via a digital temperature meter to a microprocessor, the system will only operate when the temperature is lower than a pre-set value and will shut off when the temperature is higher than a pre-set value. Wh en activated, a predetermined charge of antifreeze mist will purge the piping in ea ch bay, leaving only a small residual of antifreeze. When a bay is used, the system is reactivated, purging only the bay that has been used. The system is easily adaptable to any number of bays or areas of piping that must by protected.</p> |
