Guardian Coldroom Door Sentry

The Door Sentry will install good door policy, save energy, reduce maintenance, protect food quality and keep operatives safe.

Cold and freezer room doors remaining open for longer than necessary are a continual source of wasted energy. Door openings allow warm moist air to enter the temperature and humidity controlled room, which requires additional cooling. The higher the outside ambient temperature and humidity the greater the impact on the room. Excessive door opening can lead to ice build up in the room and put stored produce at risk.

• Saves up to 17% of cold and frozen room energy costs
• Installs good operator door policy
• Loud Audio Alarms
• Robust sensors resistant to operator abuse
• Protects food quality and operator safety
• Wall and panel mount options
• Wall mount is a quick and easy retrofit
• Non-intrusive, no cold room access required
• Compatible with existing control and monitoring
