KeepThink 3-stage ECO Controller was designed to be the most effective way of energy-saving for commercial refrigeration needs. Based on door-open frequency, we developed the well-recognized fast-react controlling mechanism featuring 3 different operation modes, which can also smoothly perform fuctions including Cooling, Defrost, Fan, Light and even Defog.
As is clearly shown in the graph below,
➣ Stage1. Business Mode,
➣ Stage2. Energy Saving Mode,
➣ Stage3. Store Closing Mode.
↻ The switching of three Modes is determined by door action signal.
Taking the supermarket freezer as an example:
-- In the morning, when salesman is loading goods, the freezer will trigger the door signal which will adjust from Store Closing Mode to ECO Mode.
-- Meanwhile, due to the flow of people in store is low at this period of time, the cabinet temperature will stay on the Energy Saving Mode;
-- Then, when more customers come and keep opening the door to buy goods, our 3-stage ECO controllers will check the number of actions set in a certain time period, then the refrigerator will return to Business Mode to bring down the temperature to its lowest.
✌KeepThink 3-stage ECO controllers based on door-open frequency are far superior to normal ECO controller with build-in RTC, because ↩
A. RTC will make cumulative errors that cannot be avoided
RTC clock needs to add a RTC chip and needs charge and discharge battery, so the cost is much higher than ours, also the clock will become 0 points if battery dies. Secondly, RTC controllers will have cumulative deviation, as a result of which it needs to adjust manually just like our watches do.
B. RTC controller can not live up to the value of energy-saving
For example, if we set to start business at 9 am, but in fact, there may not be many people visiting store even till 11 am, so at this time period our 3-stage ECO controller is able to keep pulling down temperature to its lowest, therefore reduce unnecessary power consumption.
KeepThink 3-stage ECO Controllers are especially designed for commercial display like beverage coolers, beers coolers,supermarket freezers etc. A simple universal controller like model ABU-3300 with just 71* 29 mm common size, or even think bigger, like model LW-1000 with the size of 138* 32.5mm, employs every function you possibly need to help you easily realize a high-efficiency and energy-saving cooling solution for your business.☀
