DFE Sentry III Control Panel

Manage Your Milk Cooling System with Ease

A Mueller Sentry® III control panel helps you ensure the quality of your milk by managing the essential blending, cooling, and cleaning functions of your cooler with a range of features to allow you to select the level of control that's right for your business.

Mueller Sentry III is the industry's most advanced control system. It can be programmed for any milking schedule with exact cycle lengths for cooling, precooling, agitation, and cleaning. Flashing indicator lamps show the current refrigeration or washing cycle, and a digital readout allows easy temperature monitoring. Sentry also has a precooling function to lower the cooler temperature for more efficient cooling during the second and subsequent milkings. A flashing temperature alarm indicates when milk is 44°F (6.6°C) or above, or 34°F (1°C) or below.
