A heavy-duty brewer with a color interface and slick silver exterior, the K155 OfficePRO is one of the more attractive Keurig coffee makers available.
It's UL commercial listed with a massive 90 oz water reservoir, but it isn't compatible with direct water line plumbing.
For that, you want the K150P (the "P" stands for plumbing).
The interactive color touch display is a great feature, allowing you to select brew temperature up or down in 1°F increments from 188°F-198°F. You can also set the brewer to start or turn off at given times and adjust both the brew size and the display language.
And like all of Keurig's commercial brewers, the K155 isn't compatible with the My K-Cup reusable assembly.
Keurig advertises this model as being for both home and commercial use, and they're absolutely right. It's compact and affordable enough to be your everyday home coffee maker, and its straightforward color touch display makes it simple enough to be a low-maintenance, customer-facing brewer.
You may also have noticed this K155 looks a lot like the K150. What's the difference?
This K155 has a max 10 oz brew size and is intended for office use. The K150 brews a larger 12 oz cup and is marketed as a customer-facing model.
