Standard Features:• To-the-wall mounting• Redundant refrigeration circuits• 16-ga powdercoated galvanizedsteel cabinets• Expertly loomed electrical connections• Capacities from 5 to 20 tons• UL 508A electrical panels• Freezestats• Hot gas bypass• Crankcase Heaters• CSA / UL ApprovedOptional Features and Available Options:• Reverse air flow• Full indoor serviceability• Vertical discharge blowers• Heating elements• Multiplexor: Panel capable of operatingup to four separate units• All copper coils• Custom color powdercoating• Stainless steel cabinet• Low ambient controls• Corrosion-resistant coils• Economizer• Additional filtration• Condenser air deflector• DualPac 2-unit V plenumAll-in-one.Specific Systems engineered the AirPak units to be easy to installand operate. To ensure this, all AirPak units feature standard to-thewallmounting. This requires only two small cutouts to be made orconstructed into the mounting wall, minimizing the chances for airleakage. The supplied Myers® hubs on the sides of each unit allow quickconnection to existing wiring and help limit electrical entry points intothe building.All standard AirPak cabinets are manufactured using 16-gaugegalvanized steel that has been powdercoated for extra corrosionresistance. The same powdercoating is used on the internal 12-gaugesteel components.Unlike competing products which employ ‘birds nest wiring’, SpecificSystems' employees take great care to precisely loom and label eachelectrical connection for ease of identification during maintenance orinstallation. The electrical panels are UL recognized under standard508A and are CSA approved.Also standard on all AirPak units are freezestats and crankcase heatersfor the compressors. Freezestats help prevent coils from freezing over.Often, this is caused by decreased airflow (from dust, debris, etc) or froma low refrigerant charge. Crankcase heaters help keep the refrigerantfrom condensing too early and adsorbing oil. Adsorption such as thiscauses the oil to leave the compressor, and can cause gradual or instantfailure of the compressor.Systems range in capacities from 5 to 20 tons (60,000 to 240,000 BTUH),and have many available options and accessories.Built-in Backup.The most distinguishing factor of the AirPak units, when comparedto competing systems, is the dual refrigeration circuit. This redundantcircuit allows Specific Systems' units to provide our clients with minimaldowntime, thereby increasing profits through fewer repairs.6 Specific Systems – 7655 East 41st Street, Tulsa, OK 74145

Optional Features and Accessories.A commonly ordered option is heating, availabile from 10KW to40KW. Additionally, coils can be coated with several types of corrosionprotection including Esgard, Heresite, Thermoguard, Electrofin E-Coat,and Technicoat.Another popular option is the alternating panel, or multiplexor. ThisNEMA 4 rated panel is capable of controlling up to four separate unitsand alternating the load between the individual units. See pg 15.Along with freezestats and crankcase heaters, AirPaks are available withLow Ambient Controls. This package includes a receiver and a headpressure control valve (see notes at right).To further prevent corrosion, all copper coils are optional, as is astainless steel cabinet (304 or 316). Reverse air flow (drawing air throughthe evaporator instead of pushing it through) is especially useful in dustyapplications. These options give substantial protection when used in aharsh environment. Additional filtration is available via an addon unitsuch as a sand or higher grade paper filter. Filters for AirPak units may beutilized to improve indoor air quality in buildings occupied by personnel.If the unit is designed to blow into existing ductwork, AirPak units canbe engineered with ductmate flanges, vertical discharge blowers, andeven plenums sized to meet the specifications of your application.Head Pressure Control Valveand Receiver:Operate to maintain minimumcompressor discharge pressure atoutdoor temperatures down to-10 °F. (R-407c: 180 psi; R-410A:295 psi). This is accomplished bymetering the liquid refrigerant storedin the receiver into the condenser coilThis effectively reduces the operatingsize of the coil, which raises thedischarge pressure, allowing thesystem to operate at design capacityeven at low ambient conditions.(918) 663-9321 – (918) 663-5498 fax – www.SpecificSystems.com 7

Call us to discover the bestoptions for your AirPak system.For buildings on raised platforms or piers, we offer full indoorserviceability. This option gives service technicians a through-the-wallmounting that can be fully serviced from inside, eliminating the needfor scaffolding or a man lift, thereby ncreasing safety and decreasingmaintenance downtime.Applications situated in cooler climates will certainly benefit from theheater option. With several heat capacities available (depending on unitsize and customer specification), Specific Systems' heater option willimprove the comfort level of personnel and help maintain a set humidityin the conditioned area. Additionally, a low ambient option is availablethat includes receivers and head pressure controls, along with thestandard crankcase heaters.Corrosive environments could benefit from one of the popularcoil coating options. With choices including Esgard, Technicoat, LuvataE-Coat, Heresite, or Thermoguard, Specific Systems offers corrosionprotection that is an exact fit for your application.Powder coating is standard on all Specific Systems units, and thestandard colors are shown below.

Alternating Control PanelThe Multiplexor control panel is an option provided for applicationsthat require multiple systems to be installed in a conditioned area. Thisprovides an additional redundancy, often desired for unattended sites,and provides several standard services.The multiplexor is a microprocessor-based PLC control panel forcontrolling multiple Specific Systems units. If a failure of the main unitoccurs (determined through use of multiple sensors inside each unit),the multiplexor automatically energizes another system to keep thearea conditioned and provides visible local alarms (and dry contacts forremote alarms) to notify personnel of the failure. Override of the mainunit can also be caused by a power-failure of the main unit or a high/low temperature alarm. All multiplexors include the ability to manuallyoverride and lockout main unit. Multiplexors are enclosed in hinged6" deep NEMA 4 enclosures from 16"× 14" to 20" × 24". These panelsare shipped ready for remote mounting and remote monitoring fromanother location.As mentioned on page six, Specific SystemsAirPak units are available with many additionaloptions. The most common are listed below:• Economizer – As the ambient air temperaturefalls, so falls the need for the compressors towork as much. The economizer option addsan automatic damper with controls to allowcool outside air to condition the inside space.This adds what is termed 'free cooling' to theunit, extends the life of the compressors, andconserves power – thereby saving money.• Vertical discharge blowers – For applicationswith existing overhead ductwork, AirPak unitscan be ordered with vertical discharge supplyair fans that direct the air into a plenum thatcan then be tied into the ductwork.• Auto-sequencing between systems, based on 24 hr timer• Manual selection of any HVAC system in the circuit• Automatic dual-unit operation – High or low temperature condition• High temperature alarm – Form C dry contacts• Carboline coated condenser section – For theultimate in corrosion protection, fan blades andlabels are masked off, and the entire condensersection is sprayed with a heavy coating ofCarboline. This coating is extremely resistantto the chemicals in manufacturing plants andrefineries, and reduces maintenance and repairson the units.(918) 663-9321 – (918) 663-5498 fax – www.SpecificSystems.com 15
