The machines have high-end features such as flow control from the E61 group, PID, and plumbed/reservoir operation. There are also a few key differences. Our customers must understand the differences and similarities between both machines so they can make an informed decision when purchasing one.
We decided to compare specifications, fasteners, and external fit and finish with internal and internal plumbing.
Profitec Pro 700 flow control is the most advanced in its class when it comes to dialing in perfect extraction. To extract the best flavor from your espresso, profile the shots manually using the flow control valve.
First, let’s take a look at some of the machine specifications. They are quite similar, but with some notable differences.
Both brew boilers are approximately the same in size, however, the Pro 700 offers about 20% more power. The wattage in both steam boilers is the same, but the Pro 700 has a 2 Liter capacity that is 30% larger.
Bianca has a slight advantage by running at a maximum of 2.3 bar in its steam boiler. However, you may want to consider a larger boiler to compensate for the.3 bar pressure difference. Bianca’s water reservoir is also about.5 liters bigger than that of the Pro 700.
Each machine comes with a drip tray cup riser and an actual tamper. The Bianca comes with a bottomless Portafilter, triple basket, and an additional steam tip.
The warranty on the Pro 700 is 3 years if purchased through Whole Latte Love. The Bianca is not currently available, however, the warranty may be extended to up to three years depending on the place purchased.
Pro 700 Review
Profitec Pro 700 Review
Marc reviews Profitec Pro 700, its latest features, and the redesigned group head.
The nuts, bolts, and screws that hold these machines together may not seem very important to some. They are important to us! The quality of the components used can tell a lot about the overall quality of the product, especially when manufacturers are trying to cut corners.
This is where Pro 700 and Bianca differ greatly. The Pro 700 has high-quality Allen head screws which fit into permanently attached metal nuts. To remove the outer shell, take out the four screws at the top.
We counted 17 average quality Phillips head screws for removing the Bianca case. That’s 11 on the top and 6 at the bottom. Not to be overlooked is the fact that many screws are directly inserted into plastic. Plastic can eventually become brittle. This is a way to make plastic more durable.

External Fit and Finish
You’ll notice distortions of reflections in Bianca’s front panel when you open the box. This is particularly noticeable when compared with the nearly mirror-like Pro 700 finish.
The difference in the appearance of the exterior panels and the gauge or thickness of the metal used in their construction are the reasons for the differences. The Pro 700 had a thickness of approximately 1 millimeter, while the Bianca had a thickness of.7 millimeters. The Pro 700 has a more rigid appearance due to the added thickness of its panels.
The Pro 700’s side panels can be viewed from three dimensions and are seamless. Its seams are perfectly welded and finished. This is the same quality work that you will find in Profitec machines and ECM.
Comparing this to Bianca’s two-dimensional body panels, which are simple machine-formed pieces that have folded edges that can be quite sharp in certain places, it is quite different. The Pro 700’s body panels are free from sharp edges.

The incorporation of flow control is one of the most distinctive features of both machines. However, flow control is a feature that the machines that differ from each other.
The main difference is the flow rate. The Pro 700 has an entire range of flow rates. This means that the Pro 700 can handle flow rates as low as zero flow and up to almost 30 grams per second.
Bianca is a bit different. The machine has a limit of 220 degrees of adjustment. This is because the control to the left will not allow for flow. You can reach a maximum of 8 grams per second if you move to your right. This is similar to a vibration pump machine.
You will need to adjust the handle and calibrate the machine to achieve the 11 grams per minute typical of rotary pumps. Setting it at that flow rate will increase your minimum flow rate and ensure you have no flow or low flow when the control pushes to the left. The limited range can be problematic depending on what type of profile you use.
The Pro 700 has a resolution of flow rates that is almost twice as high. To go from zero flow to 8 grams per minute, it takes a 360-degree turn. It takes the Bianca 270 degrees to cover the same area, so it is about half the precision of the Pro 700 when changing flow rates.
Calculating the Flow Rate
Introduction to Calculating the Flow Rate on E61 Machines
The latest trend in espresso is flow control. This tool allows you to extract specific flavors, aromas, and nuances from your coffee. It is now more easily available on home-level espresso machines made by Profitec, ECM, and high-end commercial machines such as Dalla Corte’s Mina.
The inside of a machine is probably the most important. The Pro 700 and Bianca both use stainless steel boilers and have tubes that direct internal water sources to outside.
Overall, the Pro 700 is a more efficient machine with a better internal design and a significantly improved layout of electrical components. They are shielded both on the top and side of the machine. Although Bianca has some shielding, it is not as extensive. The Bianca does not have shielding at the sides.
It is also worth noting that the Pro 700’s relays for powering the boilers are stronger than those in the Bianca.

The Bianca has a unique arrangement for the water reservoir. The reservoir carrier hangs from the machine. It can be moved to either the back or the side of the machine. You can also plumb the machine to take out the entire reservoir. This allows for a smaller footprint.
This setup has its limitations. It is difficult to switch between water sources because Bianca uses one connection under the machine for the reservoir or plumb line. To switch, you will need to reach under the machine to disconnect one line and then connect the other. A separate cable connects the reservoir and the machine to enable water level sensing. This tube is wrapped to carry water from the reservoir. We noticed a sharp-edged hole in the tube that runs through it. The tube could be damaged by the sharp edges down the road.
The Pro 700’s reservoir is contained within the machine. You can change between the plumbed inline and reservoir operation in a matter of seconds. To turn the reservoir’s water level sensing on or off, you just need to open a valve and set the switch behind the drip tray.

Whole Latte Love is very selective about which products it carries. The Pro 700 emerged as the clear winner after a thorough review. The Pro 700 is more expensive than the Bianca, so it’s hard to justify the Bianca.
However, we understand that the Bianca will be more expensive if you are purchasing from Europe. We want to stress that Bianca is a reliable and respected machine, especially when you consider the differences in European market prices.
