The Patented Vending Miser will reduce the power consumption of a cold drink vending machine by an average of 46%, with no impact on sales or drinks!

Vending Miser represents a technological breakthrough in intelligent and economical control of vending machines, which significantly reduces energy consumption without compromising the vended product.

Utilizing a custom passive infrared sensor , Vending Miser powers down a vending machine when the area surrounding it is unoccupied and automatically repowers the vending machine when the area is reoccupied. Vending Miser's intelligent controller uses fuzzy logic to learn from the habits of the building occupants, and modifies the time-out period accordingly.

An optional 'slave' model allows the control of a bank of vending machines with a single sensor, minimizing installation time and visual impact.

Additionally, Vending Miser monitors the ambient temperature while the vending machine is powered down. Using this information, Vending Miser automatically powers up the vending machine at appropriate intervals, independent of occupancy to ensure that the vended product stays cold.

Vending Miser also monitors electrical current used by the vending machine. This ensures that Vending Miser will never power down a vending machine while the compressor is running, so a high head pressure start never occurs. In addition, the current sensor also ensures that every time the vending machine is powered up, the cooling cycle is run to completion before again powering down the vending machine. This unique process also ensures a cold vended product.

The Vending Miser will also reduce the maintenance costs and extend the life of the vending machine by significantly reducing the number of compressor cycles that are run.

Vending Miser's unique approach to power management makes it the most advanced energy saver available.
