The Atlas DEF by Gasboy makes fleet management easy. The Atlas DEF is designed to keep things simple—it uses the same interfaces that our standard Atlas dispenser does, enabling drivers to use what’s familiar. It’s available in two different options: The Cold Weather Model and the Warm Weather Model: Cold Weather—prepared for installation temperatures as low as 10°F & comes with a heated hydraulic cabinet controlled by a thermostat. It also includes internal hose storage and an enclosed, heated nozzle hang-up created to counter freezing temperatures. Warm Weather—created for a warm environment without a heated hydraulic cabinet. Easily functions around 50°F and up.
