Designed for residential or commercial use, ONAM products are completely self-contained and do not require a refrigeration technician for installation.

Since these units do not require air venting, wall openings are not needed if the units are installed within the wine cellar. The elimination of venting requirements offers more flexibility for unit placement, resulting in a more aesthetically pleasing installation.

Depending on the model chosen, the unit is either ducted to an adjacent room or completely contained within the cellar, keeping noise levels to a minimum. They are typically installed at floor level eliminating vibration transmission to your wine collection.

Additionally, ONAM units do not reject heat into adjoining spaces but rather pump the heat into city water.

Since city water has a relatively stable temperature, your ONAM cooling unit will always operate at peak efficiency. Water consumption is fully regulated to a minimum, at approximately 1 gallon every 5 minutes.
