AIM Technologies Inc. has become familiar with certain needs of the evaporative cooling industry when dealing with the control of water quality. Development of a simple, inexpensive device to monitor water quality began several years ago. Since that time testing has been conducted which revealed substantial gains in overall cooling media condition through the use of our device. In addition, AIM Technologies is working on a new evaporative cooling device which would eliminate the problems associated with the shut down of coolers having wet cooling media. A brief description is provided below. Please feel free to contact us a should you require further information.

Conductivity Controller

AIM Technologies is finalizing it's design and testing of an electronic device to assist the evaporative cooling industry in the control of mineral build-up on the outer surfaces of cooling media. The device measures basin water quality and based upon a set limit causes circuit closure so that a pump or other device may activate renewing the base water make-up.

By maintaining water quality (conductivity level) at a desired level the formation of mineral build-up on the outer surface of cooling media can be reduced. In some areas of the country cooling media may last only 1-2 seasons when the minimum life should be 5-8 seasons. Mineral build-up can be minimized through the addition of AIM Technologies Conductivity Controller into the evaporative cooling unit or system.

The Conductivity Controller also may be used to flush the pads of a cooling unit. This method is again based upon sensing the relative mineral content of the cooling water and when necessary applying a stream of clean water directly to the media to remove accumulated deposits.

Water Level Control

Most evaporative coolers utilize a float mechanism to maintain water levels. Float devices are plagued with problems from poor flow capabilities to constant adjustment requirements. AIM Technologies produces a device specifically designed to monitor water levels and can be used to either add water in a low water condition or to alert the user in a critical no water condition. This device can be used in conjunction with the Conductivity Controller to remedy a host of Evaporative cooling problems.

Cooling Pad Dry-Out Controller

Cooling pad manufactures recommend that their media be dried prior to the shut down of the cooling unit. This drying period increases the life of the cooling pads and reduces algae growth an odor. AIM Technologies is presently developing a device which would measure the moisture content of the cooling pads and when dry signal the cooling unit to shut down. Product development is moving from engineering to prototype rapidly with field testing to begin in the Summer of 1999.
