The Grindmaster B-3WL PrecisionBrew 3 warmer coffee maker is designed to work in locations with direct water line access, as well as those without, thanks to the optional pour-over capacity that can automatically sense whether or not there is water at the inlet valve.

The PrecisionBrew capabilities in this Grindmaster B-3WL coffee maker allow for the utmost precision and accuracy in your coffee brewing. It can hold the water tank temperature to +/- just one degree of the optimal temperature setting during the entire brew cycle.

Save Energy
With a 3 warmer coffee maker, you'll really appreciate the programmable function of these Grindmaster warmers.  Rather than having them run all day long unintentionally, you can program them to automatically turn off up to 240 minutes after the last brew cycle

Dual Voltage
Not only do you have two options for filling the water tank, the Grindmaster B-3WL PrecisionBrew coffee maker is also equipped with a dual voltage toggle switch.  It will readily accept either 120/240V or 120V.  You can enjoy an even higher brew capacity at a higher voltage.

By opting to take advantage of pulse-brewing and programming the pulse-on and pulse-off times, you can extract up to 20% more of the dissolved coffee solids in each brew cycle.  As a result, treat your customers to coffee that's more flavorful and more intense.
