McQuay has taken a major step in redefining the indoor air handler with the VIsion air handler. Demands for Improved indoor air quality, low sound, high operating effi- ciency and smaller mechanical rooms require a better product for today's air handler market. The McQuay VISion air handler has been designed to meet or exceed these demands The key to providing such a high quality product IS In the basIc design. The McQuay VISion air handler's patented construction has been designed to provide unequaled thermal effiCienCies and to be airtight. In addition, VISion air handlers offer tremendous flexibility in SIZing, compo- nent options, and unit arrangements to meet the indoor air quality, operating effiCiency, sound and installation requirements for today's extensive commercial and cus- tom markets Flexibility By virtue of ItS unique frame design, the McQuay Vision air handler offers tremendous flexibility ThiS flexibility IS reflected In our unique Vanable Dlmensloning™ feature that allows VISion air handlers to be sized In two-inch Increments (height and width) to fit the available space Numerous section and component options, and the ability to arrange components In whatever arrangement required, allow ViSion air handlers to be customized to the requirements of each job Without expensive field modlfica- lions Finally, VISion air handlers can be shipped as a completely assembled unit, In modules or by component sections for new or retrofit applications that reqUire smaller sections for passage through the bUilding Cabinet .Construction McQuay VISion air handler cabinetry consists of a box- type frame channel - the backbone of the Unit - and easy- to-remove panels or hinged access doors The unique, patented frame channel deSign allows three Identical pieces to be bolted together to form a corner of the unit. Channels are formed of G90 galvanized steel or G60 painted galvanized with factory applied neoprene gasket- Ing on all flanges to minimiZe leakage. Gasketing IS also factory applied at all contact surfaces between intenor and extenor metal components to minimiZe thermal bndging Panels are secured to the Unit With fasteners that can be eaSily removed to access the Unit intenor. The frame channel and panels can be eaSily disassembled and reas- sembled, giving contractors tremendous fleXibility In installing and servicing the Units - even where space is very limited - and saving time and money. Patented splice JOints help gUide sections together for a tight fit, saving addilional time and money on installation. Splice JOints are also fully insulated at the factory. Patented gasketed frame channel ThiS unique cabinet deSign results In air tight, thermally effiCient units, which translates Into energy savings over the life of the Unit. VISion air handlers are capable of leak- age rates less than 0 5 CFM per square foot of cabinetry at 5 0" pOSitive static pressure Units Will not sweat when exposed to intenor air temperatures down to 50oF, and extenor room conditions up to 70% relative humidity. VISion air handlers are available With or without Insulation, and With Single or double wall construction Double wall units are available With solid or perforated galvanized and solid stainless steel liners Fiberglass insulation IS avail- able In 1- or 2-inch thickness and 1-1/2, or 3 pound per cubiC foot denSities The thickness of the Insulation IS never compromised for maximum thermal effiCiency A full thickness of uncompressed Insulation IS proVided through- out the unit - including underneath the drain pan. Base rails are proVided as an option on Unit sizes through 21 square feet and are standard on larger Units. They are available to meet jobslte height requirements, ranging from 4" to 12" and can eliminate the need for a housekeeping pad - saving time and money on Installation. A full penme- ter base rail per shipping section IS factory assembled "'?::. >>, <- , Patented splice joint for section to section joming 4 Cat 550-3 Access and Serviceability Equipment must be designed to perform efficiently and withstand the wear and tear of everyday use. It must also be designed to provide easy access to Intenor compo- nents for routine maintenance and service to maintain peak performance The patented frame channels and easy-to-remove panels or hinged access doors of the VIsion air handler cabinet provide complete access to the unit Interior and components Components, including the fan and cOil assembly, can be removed through the Side of the Unit, top of the unit, or a combination of both, which reduces required service clearances. COil removal on unstacked cOlis does not reqUIre access to the non-con- nection end of the COIl. A unique COil tie down method sim- plifies COil removal and replacement Easy access for routine mamtenance and servIce Top and SIde panel, frame channel removal for component replacement Vision SelectTOOLS ™ Software Selection Program Because the McQuay air handler IS so flexible and has many different component types, there are Virtually an infi- nite number of unit arrangements pOSSible To help the customer easily define their product requirements, McQuay provides a user fnendly selection program, called the ViSion SelectTOOLS ™ Software Selection Program. ThiS program configures and sizes both standard and cus- tom Units. Components can be selected in minutes. ThiS Windows@ based program Will lead the user through the selection process by prompting for pertinent Input data for all components required. Component sections are selected by plaCing them on a configuration screen. Once the unit laYDut IS defined, the options and access ones are Identified The program gives Immediate feedback regard- Ing fan and COil selection, offenng a chOice of many differ- ent options based on the performance Inputs Once final component selections have been made, the program Will provide all output needed for speCification and submittal purposes, Including fan curves, COil performance psycho- metnc charts, weights, dimenSional draWings, and a Unit speCIficatIon A fully detalled.DXF file IS also available.

Compressors Copeland's Compliant ScrolFM tandem or triple compressors are used. These rugged hermetIC compressors are constructed with an mtegral cast Iron frame, cast Iron scrolls, three Teflon Impregnated bearings, and three oil filtratlOn deVIces for each compressor. Using Copeland's ComplIant Scroll tandem compressors proVIdes two, four or SIX steps of capaCIty modulatIOn depending on model SIze. One compressor can run alone, depending on the load of the system, resultmg m excellent part-load effiCIency. Each refngerant CIrcmt has specIally deSIgned 011 and gas equalizatlOn Imes to control 011 rmgratlOn. The design also offers radIal and aXIal complIance (no tip seals), a large mternal volume for lIqmd handlIng, a removable suctlOn screen, and a rotary dIrt trap and 011 screen. In addItion, the compressor IS self-compensating for wear, handles liqmd and debns, and mherently YIelds the hIghest effiCIency for its class. ThIS well protected compressor mcludes a solid-state motor protection module, 4 mdIvIdual motor-wmdmg sensors, a patented internal discharge temperature probe, and a patented shutdown feature that prevents reverse rotatlOn. An internal dIscharge check valve helps prevent shutdown nOlse and comes standard WIth hIgh and low pressure taps WIth Schrader valves, a SIght glass, an 011 level adjustment valve, and an off cycle crankcase heater. Umts are avmlable in 60 Hertz electncal voltage configuratlOns from 208 to 575 volt operatmg at 3500 RPM. Condenser Coils Condenser coIls have mternally enhanced seamless copper tubes arranged m a staggered row pattern. The COlIs are mechamcally expanded mto McQuay lanced and nppled alummum fins WIth full fin collars. A vanety of optlOnal COlI matenal and coatmgs are available for corrOSIve atmospheres. An mtegral subcooler cIrcmt prOVIdes subcooling to greatly reduce the pOSSIbilIty of liqmd flashmg The external condenser COlIs are fitted WIth a protective WIre mesh guard as standard eqmpment. Condenser Fans and Motors MultIple dIrect drive dynarmcally balanced propeller fans operate m formed ventun openmgs at low tip speeds for maXImum efficiency and minimum nOlse and vlbratlOn. A heavy-gauge vmyl-coated fan guard protects each fan.
