2 Ultra~CPA CRITICAL PROCESS AIR UNIT The food industry historically has viewed critical process air-handling units as a key component in the refrigeration system but not a part of the Process Room. However, this is changing rapidly as equipment hygiene, designs for effective cleaning and food safety awareness increase. Today, a growing number of food processors consider the critical process air unit as an integral part of their production process and view them as a key piece of processing equipment. As a result, there is much greater emphasis on the internal construction of the unit and the ability to efficiently clean and fully inspect the equipment. These critical process air handling units must be designed to eliminate all internal areas where bacteria and other contaminants can accumulate and areas which are not readily accessible during the cleaning process. This increased emphasis on hygiene and sanitation dictates a totally new vision of how to design the interior structure and key components of the air handler; as well as, new techniques used to manufacture the equipment. EVAPCO s new Ultra~CPA System has been designed to meet the needs of today s most demanding food processing companies. As the next generation of critical process air handling units, the Ultra~CPA System is capable of handling full wash-down mode. The unit incorporates fully welded and pitched stainless steel drain pan systems. The welds are smooth and nonporous. The drain connections are fully recessed to facilitate complete drainage in all sections. The interior walls are designed to be flush with the edge of the drain pan to eliminate flat surfaces between the base of the interior walls and the top of the drain pan. The interior walls are designed to eliminate all exposed fasteners, even where the closures meet the wall. Ultra~CPA System STAINLESS STEEL DRAIN PAN Typically, interior components of the air handler are supported and mounted in a manner which does not provide complete accessibility for cleaning. For example, in conventional air handlers the heating and cooling coils are mounted on the floor using fabricated steel hat channels. This common design method results in a solid structure for supporting the coil. However, it makes the areas below and adjacent to the coil supports virtually impossible to clean and inspect. Even though there are drain pans under the coil, there is still not sufficient room to clean directly beneath the coil or under the support channels. TRADITIONAL COIL SUPPORT DIFFICULT TO CLEAN The Ultra~CPA System has a re-designed coil support system that makes cleaning under the coil both easy and efficient. There are no longer open structural steel supports under the coil which obstruct the cleaning and inspection process. The new closed coil support system eliminates hidden areas, while providing full visibility and access to the coil supports and surrounding areas for maximum cleaning efficiency.

3 In a conventional air handler, the design of the blower and motor section make it especially difficult to access and clean. Support channels, bracing, angles and other obstructions mounted to the floor of the unit make cleaning and sanitizing virtually impossible. Regardless of the number of blowers, these standard methods of installation create a real challenge for proper cleaning and sanitizing of the unit. As with the cooling and heating coils, a radical re-design which enables for full access under these components was necessary. The Ultra~CPA System incorporates a unique closed structural support system that completely eliminates the traditional support and framing around and under the blower. Ultra~CPA System BLOWER AND MOTOR PRECISION BALANCED FOR EFFICIENT OPERATION This revolutionary design makes the area under the blower and motor completely open, making cleaning and inspection simple and efficient. In addition, the Ultra~CPA System utilizes direct drive aluminum blowers. This blower design eliminates belts and the associated cleaning, maintenance and dust issues. The use of Variable Frequency Drives in the Ultra~CPA System will result in efficient fan operation, precision balancing of the system and maximum energy savings.

4 Another area often overlooked with conventional air handling systems is the lack of sufficient interior lighting for proper cleaning and inspection. The Ultra~CPA System is designed with hygienic/food grade, waterproof lights which allow for excellent visual inspection of the inside of the unit. In addition, the lights are hung from the ceiling with a specially designed offset so the light and its mounting system are easy to clean and inspect. Ultra~CPA System HYGIENIC, FOOD GRADE, WATERPROOF LIGHTS Universal, off-the-shelf filter frames are typically used in the air handling industry. They are versatile, easy to install and can be used for almost any type of filter. However, these stock filter frames are very difficult, if not impossible to clean and maintain. Their universal design requires multiple hold/pinch points, different filter clips, and numerous joints and crevices between the individual frames. The Ultra~CPA System addresses this design issue by incorporating custom designed, solid-welded filter frames designed without holes, joints, clips and pinch points. This filter frame design provides a simple, clean and sanitary mounting method for any type of filter. In addition, the frames have no gaskets. The gaskets are located on the filters which result in a new, air tight gasket every time the filter is changed. Air dampers are commonly used in air handlers. Their multi-piece blade assembly and linkage design offer numerous challenges for cleaning personnel. The typical dampers use air foil blades which are hollow on the inside. As a result, they are very difficult to inspect and clean. Also, most standard dampers have a channel frame construction which forms a pan on the top of the assembly making this area impossible to clean. Ultra~CPA System air dampers use a single blade design with removable gasket. The top of the assembly is open for easy cleaning. This design eliminates the possibility of collecting water or contaminants on the dampers.

5 Ultra~CPA CRITICAL PROCESS AIR UNIT Effective cleaning of the heating and cooling coils is another parameter which EVAPCO has addressed in the Ultra~CPA System. Heating and cooling coils are maintained in clean and contaminant free condition with the exclusive EVAPCO Sanitizing System (ESS). The ESS uses the latest high output UVC emitter technology to effectively eradicate mold and other contaminants right at the source. Properly installed and maintained ESS UVC lights will eliminate the need for coil sanitizing or cleaning. However, should coil cleaning be required, it can be safely performed without removing the UVC lights which are 100% watertight. The casing walls of the Ultra~CPA System are manufactured with heavy gauge double wall construction for long equipment life. Casing walls are ESS UVC LIGHT SYSTEM foamed in place for maximum insulation resulting in a single piece, unitary construction with no through metal design. The Ultra~CPA System has been precisely engineered to be the penultimate hygienic, critical process air system in the Food and Beverage market. In fact, every aspect of the unit s sanitary design has been addressed including the use of acorn nuts on the few fasteners that are in the unit, resulting in no exposed fastener threads for contaminants to collect! NO EXPOSED THREADS FULLY FORMED AS ONE SINGLE PIECE Ultra~CPA Systems are offered with an open platform PLC control system. This control system enables the End-user to specify the exact control sequence for the system and the specific monitoring requirements for the project. The open platform PLC control offers maximum system control flexibility, especially when compared to closed design, micro-processor control systems used by other manufacturers. The Ultra~CPA System is just not a typical critical process air handling unit. It is the NEXT GENERATION of sanitary critical process air handling systems offered for today s most demanding Food and Beverage Processors. OPEN PLATFORM PLC CONTROL PANEL
