Heat Exchanger Espresso Machines
Find the machine for your everyday espresso ritual.
Choosing your equipment
Turin Gallatin heat-exchanger espresso machines bring an E61 brewing group and a dedicated steam-boiler workflow to the home coffee bar. Compare Gallatin V and R configurations, including their pumps, flow-control options and water-supply arrangements.
How a Heat Exchanger Works
A heat-exchanger machine heats brew water through a separate passage within the steam boiler. This supports an espresso-and-steam workflow without switching a single brew boiler between brewing and steaming temperatures. It remains a different design from a machine with distinct brew and steam boilers.
The boiler setting and the water temperature at the coffee are not the same measurement. A PID helps control boiler temperature, but an E61 heat exchanger can still require a cooling flush after standing. Follow the operating procedure for the exact model and build a consistent routine.
Gallatin V or Gallatin R?
The Gallatin V uses a vibration pump and a 2L stainless-steel heat-exchanger boiler. Flow control is optional, so the selected Yes or No configuration determines the hardware supplied. It offers the traditional E61 brew-lever workflow with PID boiler control.
The Gallatin R uses a rotary pump and includes flow control. It also supports reservoir or direct-water operation. The R remains a heat exchanger; its rotary pump does not turn it into a dual-boiler machine.
Check Water Supply and Installation
Reservoir use is practical when you want to place the machine without installing a water line. Direct connection can suit a permanent coffee station, but fittings, inlet conditions and drainage must be checked model by model. The Gallatin V’s manual-valve direct connection is described for occasional use; compare R or DB for regular plumbed operation.
Leave room to access the tank, steam wand and drip tray. Measure depth with the working portafilter and front clearance, not only the body. Follow the machine’s water-quality guidance to care for the boiler and brew system.
When to Compare a Dual Boiler
If independent brew and steam temperature control is a priority, compare the Gallatin DB dual-boiler option. If you want a more compact machine with a different heating arrangement, see Legato V2 in all espresso machines. Pair either approach with an espresso-capable grinder and use a scale to establish a repeatable recipe.
Does PID eliminate cooling flushes on an HX machine?
No. It controls boiler temperature, but the brew path can still heat while the machine stands. Follow the Gallatin model’s flushing and warm-up guidance.
Is flow control included on every Gallatin?
No. Gallatin R includes flow control, while Gallatin V offers it as a selected option. Check the exact new or open-box variant before ordering.
Is a heat exchanger a dual boiler?
No. A heat exchanger uses brew-water heating within the steam-boiler arrangement. A dual boiler has separate brew and steam boilers. Both can support milk-drink routines, but their temperature-control architectures differ.

Amazing grinder and service from Turingrinders.com
I'm super happy with the new grider, solid, powerful, easy to use and perfect for my espresso machine. I have been using it for over a month and I am really enjoying it the results I get.
Great service from Turingrinders too, ship quickly, great burr aligment and 0 calibration. Could not be more satisfied !

Turin DF64 Gen 2.7 Single Dose Coffee Grinder
Royal Sipe
First espresso grinder
A piece of art that is a pleasure to use.

Love our Turin
After doing a lot of research and talking to many of our coffee aficionado friends, we decided to buy Turin DF64. And boy it hasn't disappointed us one bit. We are grinding coffee beans daily for different types of extractions. Highly recommend it to everyone.

A terrific choice for single dose brewing
If you’re in the market for well built grinder for single dose brewing and nearly zero retention, add this grinder to your cart ASAP. Pairing with my Lucca A53, I was concerned the portafilter support forks would be too large. They are in fact, but the Turin grinder is so fast, you’re not going to rest it there anyway. Even better, I can articulate the 53mm portafilter to distribute grounds around the basket while grinding. The forks are close enough to rest the PF on, just not enough to hold it unsupported. The grinder took a few pounds of coffee to break in the burrs. Straight out of the box the coffee (espresso) was just a bit flat, but now that’s done with. The Turin has gone through a few changes based on owner feedback. It’s not worth deducting a star, but I have two minor things I'd address. First, the rubber feet on the machine are leaving black marks on my counter. Petty complaint I know, but no one reaches perfection without improvement. The second is the layout of the grind setting markings. To help these older eyes, I would rather the numbers be closer to the hash marks and/or the marks be printed at different heights, similar to a tape measure. To solve the issue on my Turin, I colored over every 5th mark with red sharpie and now it’s ridiculously easy to get a quick read on my settings. The subtle pop of red looks good too. It’s fast, relatively quiet. Easy to keep clean, has nearly zero retention and looks perfect next to the LaSpaziale.

From DF83 toDF83v
After 3 years of daily 1st Gen DF83 use… A user abuse left me in need of a replacement espresso grinder.
The DF83v was ultimately what I committed to purchasing.
Every step of my daily coffee is improved.

Amazing
It's beautiful. Design is stunning. The control over grind is very precise. My espresso is now perfect. So little retention with the bellows. If you are crazy OCD then blow it out with a Wolfbox blower on high after using. What a deep dive down the engineering rabbit hole of perfectionism. I sometimes pull out the antique hand grinder for a rough irregular grind of cheap beans and make some boiled coffee to keep grounded.

Good one!
I waited almost a month for my order to arrive and that was not necessarily what I was expecting but I stuck in there until it finally did. Now I am enjoying truly excellent lattes which was my goal. It was easy to setup and use and that’s a plus. Since it is still new I don’t have any issues to report such as ease of cleaning etc but it seems fairly straightforward. Bottom line for me: worth the wait.
EEV from Maryland
Grinder with European voltage
Very fast und reliable, they even reimbursed me as it was clear, that I live in the US.
