PRECISION MACHINED ARTISAN CNC PRODUCTS

OPERATION AND SPECIFICATION
 

 

The Lunar Espresso Module pays tribute to the incredible engineering, craftsmanship, and courage the men who made it happen possessed. Starting with a design that gives a retro haptic experience through robust dials, switches, and analog gauges, it is precision machined and built in the USA.  The machine is a work of CNC art with its machined chassis of type III hard-coated 6061 aluminum and carbon fiber. The plumbing, fittings, pump cylinder, and reservoir are all stainless steel. Like the cockpit of the original Lunar Lander, it features a simple green readout for the onboard sensors. As with the Lunar Excursion Module, this machine is meant to be piloted. You are in full control of every parameter required to make the perfect shot. You have precise control in real time and on the fly- no programming - of the pressure, temperature, and duration at extraction. The Lunar Espresso Module promises the most fun you'll have making espresso.

   
CARBON FIBER PORTAFILTER

On July 20, 1969 the Lunar Module landed on the moon with two men aboard - an achievement that is arguably the greatest engineering feat of all time.

START UP

 

Starting with filling the tank and switching it on, the LEM heats 20 C water in the reservoir to 100 C in 180 seconds. The manual control over temperature and pressure without the need for programming allows for the piloted feel of operation with the LEM.  However, there is PID controlled temperature regulation of the reservoir temperature with the small red knob on the control. When making changes to reservoir temperature, your setting will be achieved and shown in the reading next to "TANK". The reading next to "GROUP" is a function of both the temperature in the reservoir and the position of the Heat Exchanger Dial as discussed below.

PRESSURIZE RESERVOIR

 

Pumping the hand pump 5 times at start up creates a reserve pressure of about 5 bar inside the reservoir. As the machine heats up this pressure will increase to about 10 bar which is your reserve pressure used and controlled during extraction via the red Extraction Knob located on the side of the grouphead.

Rotating the Heat Exchanger Dial to the full right position during heat up allows for the quickest transfer of heat to the grouphead. Once the machine is heated to the desired temperature, the Heat Exchanger Dial can be used to fine tune the brewing temperature by rotating to the left for gradual modulation of heat transfer to the finned heat sink bevel around the gauge. Full right for maximum heat transfer to the grouphead, full left for minimal transfer, and a modulated adjustment anywhere between the two positions.

Feedback on your settings can be seen on the display next to "GROUP".

LOAD THE COFFEE

 

The properly dosed and tamped coffee can be loaded directly into the clean machine. If a purge is desired for a cleaning flush this can be done using the Extraction Knob. If a purge is done, use the hand pump to bring the pressure back to 10 bar before pulling the shot.

PULLING A SHOT

 

Finally, with temperature and pressure set, its time to fly the machine. Slowly crack the red Extraction Knob to let a little water in for pre-infusion. Once you see a few drops coming from the portafilter, open the valve at the rate you desire for the pressure you desire at the time you need. You are piloting the machine to profile the perfect shot.
