For those not familiar with this beautiful machine, the Expobar Office Pulser is constructed with a high polished stainless steel apart from the front panel that has the steam and hot water knobs which come in black painted or enameled steel.
The Expobar Office Pulser is also quite big (40 lbs), with a nice sized warming tray, while some customers have said that the plastic drip tray itself is not huge, holding around 600-700cc of water.

A porta-filter is inserted into the solidly made piece of chrome-plated brass which is the porta-filter holder.
The Expobar Pulser brew group is equipped with a thermal siphon that has constant circulating water through it to keep it hot at all times. You don’t have to run a blank shot to preheat it.

Expobar has a copper boiler with a capacity of 1.8 liters.
The internal heat exchanger prevents the water used for brewing from coming in contact with the water stored in the boiler for steaming and hot water dispensing.
You can actually brew and steam or dispense hot water at will as this is a fully commercial-friendly design.
Indeed, Expobar Pulser has been designed for commercial application of any kind, such as a café or restaurant environment.
This is a machine that has a 3-way solenoid valve which is a commercial feature that relieves the water pressure off the coffee when the brew switch is turned off.
This has two functions – it dries out the coffee to prevent dripping and makes it easy to knock the coffee out of the porta-filter with one knock.
When comes to machine controls with the Pulser, they are easy to operate and understand; training is not a must.
All you have to do is 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.
You know that a cup warming machine is a great thing, especially if you are looking for a professional espresso maker.
A non-preheated cup will suck the heat out of the espresso therefore you won’t really have the original taste of your coffee.
The cup warmer on the Expobar holds up to 14 espresso cups. We talk about a passive type heater; it is heated from the residual heat of the boiler.
Hot water dispensers are amazing 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.
The wand is attached on a ball joint and just like most commercial style machines it can pivot in any direction.
The steam wand is long and is high enough off the counter and easily fits any frothing pitcher without having to tip it. Just like the water wand it pivots in any direction.
Expobar Office Pulser Espresso Machine has a 2.75 liter reservoir that is easily removable for cleaning or filling at the sink.
Maintenance Of The Expobar Office Pulser
In our opinion, to keep it in tip top shape, the Expobar Pulser should be maintained every few days.
If you are using the machine every day you should back flush it at the end of every day. The process takes a few minutes.
Put a blank filter basket into the portafilter and add a tablespoon of cleaner, then install the portafilter into the machine and turn on the pump.
The process will be loud when it starts and will quiet down as the pressure builds.
Once 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.
Don’t stop the process until the cleaner that was directed into the drip pan has no longer any brown color. Finish by rinsing out the brew group.
The Expobar Office Pulser is not an inexpensive purchase. That said, it offers a professional grade espresso machine for both the home user and also for business owners.
There are a few small drawbacks, in that not every inch of the Pulser is made from metal, but this is how the Office Pulser is made to be affordable.
Overall, it is definitely a 4 STAR machine.
