Overview
The Micro Matic HYDRO MM-WD-20 is a complete filtered water on tap system that serves three waters from a single chrome tower: ambient still, chilled still, and chilled sparkling. A three-button control box sets the selection, and an under-counter chiller and carbonator do the work out of sight. It is Micro Matic's low-volume HYDRO system, sized for small offices, cafes, and home use.
Built for small spaces and steady service
The chiller and carbonator fit an install footprint of 11"W x 19"D x 16"H and mount in a vented cabinet, with the tower mounted on the counter above. Micro Matic's recirculating cold-loop design keeps water chilled right up to the point of dispense.

- First hour (full ice bank): 5.5 gal/hour, about 58 12-oz cups
- Second hour and on (compressor only): 2.1 gal/hour, about 22 12-oz cups

Before you order
- CO2 cylinder not included. You'll need a CO2 supply for the sparkling option; the system ships with the high-pressure regulator.
- Water pressure: a water booster is required if your incoming water pressure is below 50 psi.
- Installation: the chiller and carbonator install in a vented cabinet; the tower mounts on the counter.
Why water on tap
Filtered tap water costs a fraction of bottled water and removes the need to buy, store, chill, and dispose of single-use bottles. That frees refrigerated space, saves staff time restocking fridges, and keeps plastic and glass bottles out of the waste stream.
Why Micro Matic
Micro Matic has built beverage dispensing systems since 1953. The HYDRO MM-WD-20 is NSF certified, cCSAus listed, made in the USA, and backed by a 1-year parts and labor warranty.
