spears
Micro Matic or DSI, we have the perfect spear for your needs
Fifty years of quality spears
Micro Matic entered the beverage dispense industry half a century ago by engineering high-quality keg spears for a major European brewery. That successful venture led to our getting into other dispense equipment – while we also kept innovating our spear technology.
Today we’ve sold more than 135 million keg spears worldwide. Our customers value the two distinct designs we produce for their unmatched precision, safety features, and hygiene certainty.
Always more than meets the eye
Think keg spears are simple products? The truth is, they are deceptively complex, with the design and engineering of each individual part critical for ensuring safe, hygienic, and reliable operation.
Two great Designs, endless possibilities
Via our Micro Matic and DSI spear designs, we offer valve systems for all common threaded and bayonet necks. All standard neck and coupler interfaces are available, plus the option of customized designs. And we offer different safety technologies based on valve/ spear and neck type.
All Micro Matic and DSI spears meet EU and U.S. food-contact requirements and feature safety technology that protects your employees and customers. Our spears are easy to handle during assembly, disassembly and maintenance.

The right length of spears
The H3 dimension of the keg is defined from the sealing edge in the neck down to the bottom cup in the keg. This is important for the correct length calculation of the required spear. This is because the correct bottom distance per valve system must be selected in order to be able to realize the strokes that occur and to be able to carry out cleaning, filling and emptying correctly.
| System | Ground distance in mm |
|---|---|
| A/G-type | 9 |
| M-type | 15 |
| S-type | 14 |
| D-type | 14 |
| U-type | 14 |
All about color coding
Invented by Micro Matic, the color coding of keg spears is a maintenance approach that uses a new color each year to enable camera-controlled or mechanical separation of kegs for scheduled maintenance.
By facilitating preventative maintenance, this ensures a greater return on investment and reduces the risk of unplanned maintenance and downtime.
Color-coding of the spears enables camera-controlled or mechanical separation of kegs that are due for routine, scheduled maintenance which Micro Matic recommends at approximately 7-8 year cycles.
Please note that the above screen colors are only indicative.
