 Rebuilt Machine Overview

Our rebuilt machines were entirely dismantled, cleaned and extensively rebuilt. The whole boiler assembly and all of the copper tubing was removed and thoroughly descaled. We then rebuilt the boiler, brew group, pump assembly and valves, cleaning, replacing and lubricating parts as necessary. Our entire process is described in detail below. 

Total Tear Down and Rebuild Process:

  • Boiler & Piping Assembly: first we installed all NEW parts including a heating element, pressurestat, safety valve, vacuum relief valve, high limit switch, and boiler insulation.
  • Brew group: we then did a complete tear down, cleaning and lubrication of the brew group and installed all NEW brewing, infusion and discharge valves along with their seals, the upper and lower infusion valve springs, the shower screen, and group gasket.
  • Pump Assembly: the rebuilds all feature an all NEW pump, OPV & air remover, and style fitting with heavy duty teflon tubing. 

Testing Phase:

  • When the machines were reassembled, we adjusted the steam pressure to 1 bar; and, with the backflush disc in, we set the brew pressure to 10 bars.
  • Post-reassembly, we thoroughly tested the machine’s steaming, brewing and pre-infusion performance, and made sure the sound level it produced was no louder than on a new machine. 

When you Buy:

The rebuilt machines include the following accessories: a portafilter, single and double filter baskets, a backflush disc, tamper, coffee scoop, and a large particle filter. 

Warranty:

Our rebuilt espresso machines are covered by a 1-year parts and labor warranty.

Machine Overview

The Expobar Office Pulser commercial espresso machine is one of a kind with a combination of low cost and high quality design and construction. It is a machine that will last a lifetime in home use and is suitable for the office, coffee kiosk, small cafe or hotel coffee bar. It can brew and steam at the same time making it ideal for any type of home use, small deli or bagel shop. The separate hot water dispenser and steam wand are mounted on a 360-degree ball joint. The group head is comparable to the renown E61 group head with pre-infusion and thermal siphon for maximum temperature stability and aroma extraction. Its electronic boiler controls, safety switches and internal components mirror those of the larger commercial espresso machines. The Expobar Office Pulser is short enough to fit under a 16” high cabinet and is only 9.5” wide. The stainless steel housing gives it as much form as it has function. The accessories include a chrome plated brass portafilter, tamper, single shot filter basket, double shot filter basket and a 7 gram coffee scoop.

Please Note: Regulations for commercial use vary between states. Be aware of your local requirements. Machines carrying an NSF approval are labeled as such.  

Features & Benefits: Coffee

Commercial Size and Style Portafilter Handle

Made of chrome-plated brass for excellent heat stability, which is essential for producing top quality espresso.

Commercial Brewing Group

The brew group is the large piece of chrome-plated brass that the portafilter inserts into. The Expobar brew group has a thermal siphon that is constantly circulating water through it to keep it hot at all times. It is never necessary to run a blank shot to preheat it.

Commercial Design Heat Exchanger Boiler System

The all copper boiler has a capacity of 1.8 liters. It has an internal heat exchanger that prevent the water used for brewing from coming in contact with the water stored in the boiler for steaming and hot water dispensing. With its commercial style design you can brew and steam or dispense hot water whenever you want to. This is especially important when entertaining or when used in a commercial application.

3-Way Solenoid Valve

The 3-way solenoid valve is a commercial feature that relieves the water pressure off the coffee when the brew switch is turned off. This serves two functions; it dries out the coffee to prevent dripping and makes it easy to knock the coffee out of the portafilter with one knock. It deposits this water into the drip tray.

High Quality Controls with Temperature Ready Light

The controls are easy to operate and understand, no training necessary. Just turn on the main power switch and the boiler will fill with water on its own and start to heat up. When the temperature ready light goes off you are ready to go ahead and start brewing.

Cup Warmer

We always preheat cups when brewing espresso. A non-preheated cup will immediately suck the heat out of the espresso thus robbing you of maximum enjoyment. The cup warmer on the Expobar will hold up to 14 espresso cups. It is a passive type heater, which means it is heated from the residual heat of the boiler.

Features & Benefits: Frothing and Hot Water

Hot Water Dispenser

A hot water dispenser is excellent for preheating cups or supplying hot water for tea. The knob on the right side controls the flow of water through the hot water dispensing wand. Just like on the large commercial machines the wand is mounted on a ball joint and can pivot in any direction.

Steam Wand

The steam wand is long and is high enough off the counter to easily fit any frothing pitcher without having to tip it. It is mounted on a ball joint that can swing in any direction.

Features & Benefits: Care, Maintenance & Other

Water Reservoir

A 2.75 liter reservoir is easily removable for cleaning or filling at the sink.

Warranty

One year parts & labor warranty

Multiple Safety Switches and Controls

If the water level in the boiler gets low the electronic controls sense this and turn the pump on to automatically fill the boiler. If the reservoir runs out of water a CPU board will turn off the heating element to prevent overheating. A manual reset high temperature switch is located on top of the boiler as a secondary safety switch.

Boiler Pressure Control

The boiler temperature/pressure is controlled through a professional grade pressure controller. It senses the pressure in the boiler and turns on the heating element in the boiler as the pressure drops.

Maintenance

Back flush the Expobar at least every few days. For commercial application you should back flush it at the end of every day. It is a simple process that takes only a few minutes. Put a blank filter basket into the portafilter (supplied) and add a tablespoon of cleaner. Install the portafilter into the machine and turn on the pump. The pump will be noisy as it starts and will start to quiet down as the pressure builds. When the pump has quieted down, turn off the brew switch and the cleaner will be blown up into the brew group, through the three way solenoid valve and down into the drip pan. Do this until the cleaner that is being directed into the drip pan is just free of coffee colors. Finish the process by rinsing out the brew group.

Housing Construction

The steel frame compliments the highly polished stainless steel housing and cup warmer. The drip grate is stainless steel and the drip pan is plastic that holds up to 32 ounces of water before it need to be emptied.
