Benefits of technology

The present invention is a compact cooling unit that has a unique combination of coils, blowers, and other components. The cooling unit can easily redirect cooled air flow to various applications. The main advantage of this invention is the creation of a twin cross flow blower system which is efficient in moving cooled air to a targeted area. The configuration of the center cross flow motor flanked by two cross flow blowers placed over a compact coil system is much lighter and smaller than the related art. The invention also presents a new salad bar cooling system that overcomes shortfalls in the art by use of air circulation and air return systems that have achieved excellent results in real world commercial applications.

Problems solved by technology

While Gaetke does provide a portable solution, Gaetke's flexible surfaces and lack of integrated refrigeration makes Gaetke poorly suited for permanent salad bars, such as those found in restaurants.
Kritzer fails to disclose means of artfully configuring cooling units to efficiently cool a salad bar.
Unfortunately, the system disclosed by Haasis leads to added noise and motor vibration due to the use of springy metal strips to secure the sub-unit to the housing.
When a fan motor needs replacement, the typical service technician will not have the necessary sealants, which results in a newly installed motor causing unacceptable noise and vibration.
Another shortfall in the Haasis system is the inefficiency of using one motor to turn a single traditional centrifugal fan.
The added load to the motor from the second cooling fan often creates more heat than what is removed by the second fan.
Furthermore, the coil configuration of the Haasis system fails to adapt to varying food storage containers or other applications with untraditional dimensions and access problems.
Moreover, the overall configuration of the Haasis system leads to a heavy cooling system making installation difficult in overhead locations.
