If you own a grocery store or a convenience store, you would know how vital it is for you to have a door frame heater for your display refrigerators. If this devise is absent, the display case would be foggy, thereby, preventing the customers from viewing what is kept inside. This can directly impact your sales revenue. The process of condensation that forms this fog can be prevented only with the help of these anti window fog heaters. The cool air at the refrigerator doors that comes in contact with the hot and humid air outside generates the fog. The heaters will help you keep the refrigerator door warm enough to prevent condensation. However, unknowingly, you are spending too much money for this process. You might know that there are very few days or months in a year in some countries where the heaters are required. Condensation occurs only if the air outside is too humid. As the heaters are in-built in most of the refrigerator doors, they function almost every single day in a year, thereby, wasting energy. Also, you are constantly paying increasing energy bills.
Today, there are anti window-heater fog managers or controls available in the market which can automate the functioning of the heaters depending on the environmental conditions. The device would pay for itself in few months, and hence, you can consider this is as a worthy investment. The small and discrete sensors are another noticeable feature of this devise.
