Cold rooms can have a lot of extra features to improve day to day operations and performance: Most will come with an automatic defrost that actively melts ice. All modern cold rooms will have an emergency escape, in the form of an internal button that opens the door. Some may also include a panic button inside. Automatic or manual interior lights are usually fitted as standard. If you use trolleys to load stock, a ramp can be added. This also helps to reduce the trip hazard from the raised door frame. Self closing doors are sometimes present to help reduce running costs.
