− | == Machine Description ==
| |
− |
| |
− | The Expobar Brewtus IV is a dual boiler Commercial and prosumer espresso machine equipped with a vibration pump. Two copper boilers let this Expobar dedicate one exclusively to brewing and the other to steaming, frothing and dispensing hot water. New to the fourth generation of the Brewtus line is a dedicated switch that will allow you to turn off the steam boiler and operate with just the brew boiler. Doing so will result in quicker warm-up time as well as yield lower operating costs in the long run.
| |
− |
| |
− | The Brewtus IV is also outfitted with a Gicar-build PID (Proportional-Integral-Differential) controller that will let you monitor and adjust brew boiler temperature. As with all Expobar machines, the Expobar Brewtus IV comes with a chrome-plated brass E-61 brew group that has been proven to excel at maintaining stable brewing temperature. The machine also features a commercial grade steam boiler and commercial style steam wand assembly.
| |
− |
| |
− | The Expobar Brewtus IV equipped with two copper boilers—one for steaming and the other for brewing. Each boiler is outfitted its own 1250-watt heating element and can operate autonomously. The boilers are set to the appropriate temperature for their individual functions and their environments will not fluctuate when you alternate between brewing and frothing. This temperature stability will allow you to achieve consistent results as well as permit brewing and steaming functions to be performed simultaneously.
| |
− |
| |
− | The Expobar Brewtus IV has a body made of heavy-gauge polished stainless steel. It features a passive cup warmer and a large drip tray. The Expobar Brewtus IV has a large 90oz reservoir with an optional water softener. The water tank can be removed for hassle-free refilling and maintenance.
| |
− |
| |
− | The Expobar Brewtus IV comes in three separate versions: a vibration pump version, a rotary pump version, and a plumbable version.
