Wine Guardian systems can be installed in many configurations, depending on the specific system, so you are sure to find a Wine Guardian that is right for your cellar.

Here are some tips for selecting the right Wine Guardian cooling system for your wine cellar.

Remote Sensor

Heat rises. That's why it's warmer upstairs than downstairs in many homes. The same thing can happen in your wine cellar, with the top of the wine cellar several degrees warmer than the floor. With Wine Guardian, several temperature/humidity sensors can be connected to one system, averaging their readings for more accurate wine cellar temperature control.

Wine Guardian sensors measure both wine cellar temperature and humidity, allowing the equipment to adjust both temperature and humidity accurately and simultaneously. They measure the conditions in the air, not in the bottle, allowing the system to spring into action before there is any change in the temperature of the wine itself.

Low Ambient

Factory mounted control system to protect the refrigeration system when exposed to temperatures below 40℉ (5℃).


Remote Interface Controller

Remote Interface Controller - monitor and or control temperature and humidity from a remote location to ensure an optimal wine cellar environment

  • For ensuring an optimal environment for your valuable wine collection
  • Monitors the temperature and humidity of your cellar conditions and continuously displays them to another location (e.g., outside the wine cellar, kitchen, office, PC)
  • Alarm will notify you if your cellar is out of optimal range

Separate Remote Sensor is available also.

Can be used in conjunction with the Remote Interface Controller to sense multiple locations within the wine cellar or for use in remote monitoring of the wine cellar environment.
