Cooling with the Wizard

reenheck’s Water Wizard provides complete evaporative cooling control. The Wizard measures the outside

G
temperature and humidity then adjusts the water supply to provide only the water needed for maximum
evaporative cooling. On cool or humid days, the Wizard knows the evaporative cooling potential is low and

educes the water supply to save you money. On hot or dry days, the Wizard increases the water supply to

r
meet the increased evaporative cooling potential, providing you with the most cooling possible.

Water Wizard Features

Freeze Protection

The Wizard protects the evaporative cooler from
freeze damage by automatically shutting off the water
and draining the supply line when the outside air
temperature approaches freezing.

User Friendly Interface

Four control keys and a large LED display provide a
simple and user friendly interface.

Easy and Accurate Set-Up

Factory provided pressure gauge and manual supply
valve are standard, allowing the optimum water
pressure to be quickly and accurately dialed in for
peak performance.

Field Adjustable

The factory default settings are easily adjustable,
allowing you to maximize your cooling and savings.

Optimum Evaporative Cooling

The Water Wizard guarantees you the optimum
evaporative cooling cycle for your conditions.

1. Warm air enters the media.

2. Water evaporates and the airstream cools.

3. Cool air discharges from the moist media and the
water supply replaces the water that was
evaporated.

Varying Humidities

Even in the best evaporative cooling climates, the
evaporative cooling potential can vary greatly from
day to day. With the Wizard, you can always be sure
your evaporative cooler is optimized – on a dry or
humid day. Consider the following example at a
95ºF Td*.

A. On a day with a 67ºF T

GPM of water and maximum cooling.

B. On a day with a 73ºF Tw, the Wizard reduces the

water supply to 1.9 GPM, saving you water while

oviding the maximum cooling.

C. On a day with a 60ºF Tw, the Wizard increases

the water supply to 3.0 GPM and provides you
with the maximum evaporative cooling.
