Designed in-house, Auto-Start™ technology provides automated protection against frost. Created with settable start and stop temperatures, you control the temperature at which the machine turns on and shuts down. Our Auto-Start™ accessory is accurate to +/- 0.5°F (0.3°C), providing you the peace-of-mind that your crops will continue to thrive. This accessory is an option for all new Orchard-Rite® wind machines and can be retrofitted to most other makes and models.
