Air Cooled Condensing Units 3 to 22 HPThe outdoor housings of our condensing units have been completely re-engineered. Access to all components is now more convenient than ever. Quick removal of top and side panels allows quick access to everything. The hinged control panel door swings wide open for maximum clearance while the unit is being serviced.

The large control panel has abundant space for the controls you choose. They are intelligently arranged and laid out in a logical fashion which is easy to understand and work with. Each control and wire is clearly marked with a name or number as shown on the wiring diagram which is conveniently affi xed to the control panel door.

WITT-SAVER

The initial cost of quality refrigeration equipment is a substantial investment. But the costs of installation and operation are also formidable. Rising to the challenge, Witt engineers have designed the WITT-SAVER system to meet the highest standards of performance and reliability while effectively addressing the problem of these profi t draining costs.

REDUCED INSTALLATION COSTS

The installation of a refrigeration system using WITT-SAVER requires a smaller refrigerant charge than equipment which utilize other types of low ambient controls. As the more expensive zero ozone depleting, refrigerants become the refrigerants of choice, the reduced charge requirements provided by WITT-SAVER affords substantial and immediate cost saving benefits.

REDUCED OPERATING COSTS

The most expensive part of an operating refrigeration system is the cost of energy to operate the compressor. Day and night, year after year, the cost of electricity to operate your equipment is unrelenting. These dollars are pulled right from your bottom line.

A typical installation provides for equipment which is designed to furnish adequate cooling onthe hottest of days. The WITT-SAVER system is designed to meet this need but also be flexible enough to take advantage of reduced ambient conditions during off-peak times. As the outside air temperature decreases, head pressures are allowed to drop. This action results in increased efficiency, requiring less energy and saving substantial amounts of your money!

WITT-SAVER even saves money during hot weather.

The sub cooling loop provided in the condenser of the WITT-SAVER condensing unit increases the system efficiency 1/2% for each degree of sub cooling provided, thereby making the compressor’s job easier. WITT-SAVER’S efficiency saves you money during summer operation and even more during the winter months.

WITT-SAVER

ENERGY SAVINGS CALCULATIONS

To estimate your average monthly savings:

1) Select a WITT-SAVER system that meets your refrigeration requirements.2) Determine the Average Annual Outdoor Air Temperature from the table below.3) Using the Projected Monthly Savings graph, locate the system nominal horsepower at the bottom of the graph

(the nominal system horsepower can be derived from the model number nomenclature).4) Go straight up to the appropriate Average Annual Outdoor Air Temperature curve, and then go horizontally to

the left to determine your Estimated Monthly Average Savings.5) To calculate your Estimated Monthly Saving for an energy cost other than $0.10 KWH, divide the Estimated

Monthly Savings by 0.10 and multiply by your local electric utility rate.6) To determine your Estimated Yearly Savings, multiple the Estimated Monthly Savings number by 12.
