Model B-DGP is like the B-DAP, except that it is meant to be used with 2.5 liter thermally insulated Gravity Airpots. The 2.5 liter Gravity Airpots are taller than the 2.2 liter airpots used with the other brewers. Each Gravity Airpot has a spigot that is suspended above cup-level, so that patrons can server themselves merely by opening the spigot valve.
The B-DGP contains two digitally controlled brewers. Since the Gravity Airpots keep the coffee hot, the B-DGP unit does not have warming plates. The two brewers operate independently. Each brewer can maintain precise (+/- 1 degree) brewing temperature during the brew cycle. Both the brewing temperature and the volume are programmable. Note that the Gravity Airpots are NOT included. Unit comes with stainless steel filter baskets. There is a hot water spigot on the front of the unit.
