The Expobar Brewtus IV-R is one of the most advanced semi-automatic espresso machines available to the prosumer and light duty commercial market. This model features two independently operated boilers, one for brewing and the other for steaming. By having two boilers, result in greater brew temperature stability and superior steam pressure.
Exclusive to the Brewtus IV models, is a dedicated control switch that lets you deactivate the steam boiler and operate just the brew boiler. Exercising this option will significantly decrease heat-up time; in fact, the Brewtus IV-R can go from a cold start to 201 degrees, ideal brewing temperature, in about 15 minutes. If you decide that you want to froth some milk, flip the steam-boiler control switch and in approximately 10 minutes the steam boiler will be ready to steam. This smart system can lower operating costs and result in quicker warm-up time, since you won’t have to wait for the steam boiler to heat up.
Like its predecessor, the Brewtus IV-R features a Gicar PID (Proportional-Integral-Differential) controller and rotary pump. The PID control lets you monitor and adjust brew-boiler temperature to suit your preferences. Further contributing to the Brewtus’ heat stability is the chrome-plated brass E61 brew group with thermo siphon system. The Expobar Brewtus IV-R is equipped with a commercial rotary pump for smooth, quiet operation; it is recommended for high-end home use.
Note: The Expobar Brewtus IV-R does not have an on-board water reservoir. It is designed to be directly plumbed into a water line.
Regulations for commercial use vary between states. Be aware of your local requirements. Machines carrying an NSF approval are labeled as such.
No-Burn Steam Wand and Hot Water Dispenser
The steam wand is insulated and will remain cool to the touch, even when it is in use. It is equipped with a one-hole commercial steam tip that allows for maximum control when steaming or frothing milk. The hole in the steam tip is sized so that you can get non-stop steam from the steam wand. This Expobar model also has a separate hot water dispenser for your convenience. Both the steam wand and hot water dispenser are mounted on ball joints and can be rotated to accommodate different-sized cups and pitchers.
Commercial Rotary Pump
The commercial, 120-watt rotary pump is designed to work with a plumbed water line. In most cases, you will not need a pressure reducer as it can run on incoming water pressure between 5 and 65psig. You can also drop the stainless steel water intake line into a large water jug, if you prefer not to plumb the Expobar Brewtus IV-R; but please be careful not to let the pump run without water, as this can cause damage to the machine.
Additionally, you can run a drain line from the drip tray to eliminate the need to empty it by hand. To set the drip tray up to work with a drain line, a hole will have to be drilled into the drain pan. We are happy to modify the drip tray here, at Whole Latte Love, or you can do it at home. If you set the machine up with a water line, we recommend that you also hook it up to a drain line.
Brew Boiler Shut-Off Option
If you only want to use the steaming and hot water dispensing functions of the machine, you can turn off the brew boiler. To turn it off, push and hold the “up” arrow on the digital display for 2 seconds, the display will then say “off.” To turn it back on, just push and hold the “up” arrow for 2 seconds.
Manual Three-Way Valve
Lift the brew lever to start the pump and it will also open the three way valve and allow the brewing process to begin. When the extraction process is complete, lower the lever. The pressure and water in the brew group will be released into the drain pan, leaving you with a nice, dry puck. In addition, the three-way valve will allow you to easily clean the brewing components of Brewtus IV-R by backflushing the machine. We recommend that you backflush your machine every 7-9 days.
Steam Boiler Control Switch
A dedicated control switch, located on the front panel of the machine, lets you turn the steam boiler off. This allows you to run the brew boiler and extract espresso without having to wait for the steam boiler to heat up. You can expect lower operating costs with this unique system as well as quick machine warm up time. The Brewtus IV-R can be ready to brew in less than 15 minutes. Once the steam boiler has been switched on, it will be ready to go in under 10 minutes.
PID Temperature Control
The Gicar-built PID control is designed to keep brew boiler temps stable. You can also use it to adjust your boiler temperature to suit a variety of espresso roasts. The system sends pulses of electricity to the brew boiler to ensure that it is evenly heated, without over heating so that you can maintain a very steady brew temperature.
Housing and Construction
The Expobar Brewtus IV-R is a solidly built machine; it is encased in a heavy-gauge stainless steel frame. The polished mirror finish and classic styling gives this machine a stately appearance that will complement most home kitchens.

Improved E-61 Brew Group and Portafilter
The Brewtus IV-R is outfitted with the renowned chrome-plated brass E-61 Brew Group, celebrated for its ability to offer unwavering temperature stability. It is backed by a state-of-the-art thermo siphon system that circulates hot water from the boiler to maintain group head temperature. New to the forth generation of the Expobar Brewtus machines is a concave pre-infusion chamber that allows hot water to be evenly distributed through coffee grounds for superior espresso extraction. Unlike conventional E-61 brew groups, this group head directs water through the brew group in a concentrated stream. Once the water hits the center of the shower screen, it floods back up into the pre-infusion chamber before being evenly dispersed through the coffee grounds for uniform saturation during the pre-infusion and brewing process. Accompanying the E-61 Brew Group is a professional chrome-plated brass 58mm portafilter as well as single and double-shot filter baskets.
Brew and Steam Pressure Gauges
The steam and brew-pressure gauges are located on the front panel of the machine for quick reference.
The steam boiler and the brew boiler each have their own 1250-watt heating elements for fast, temperature-accurate performance. The boilers are made of copper and having two of them means that individual boiler temperatures can remain constant as you go back and forth between brewing and steaming. Each boiler is set to the appropriate temperature for its designated function. Double boilers also make it possible to brew and steam at the same time, which is perfect if you’re making a few drinks at once.
