Founded in 1951 within

the shipyards of Lake Erie

as Perry Ship Building,

PSB Industries assistance

in the construction of

bulk-carrier lake freighters

plus its expertise in the

repair and alteration of

boilersearned the

company a reputation for

excellence that continues

today. PSB Industries

offers a legacy of crafts-

manship and innovation

to its industrial packaging

and manufacturing cus-

tomers throughout the

world. From its highly

skilled workforce to its

unique manufacturing

capabilities, PSB is well

equipped to handle any

size jobfrom concept to

completion, and beyond.

ISO 9001 CERTIFIED

General Air Division (formerly a division of Zurn

Industries) specializes in compressed air, gas, and liquid

dehydration/purification technologies and offers a diverse

line of product applications. Our packaged systemsfrom the smallest to the largest applicationsremove

moisture and contaminants from process streams.

General Airs custom-designed Hydryers are specially

constructed to our customers specifications for gas and

liquid processes, unlimited in size and capacity, and are

designed for maximum efficiency. Meeting this manu-

facturing challenge, General Airs own facilities, as well

as our key worldwide alliances, are well-equipped to

handle our customers wide range of requirements.

PSB ENGINEERING AND FABRICATION

Customers worldwide have benefited from PSBs proven expertise

in the assembly and fabrication of industrial products, fromadsorption, compressor and pump skids to pipe racks, burnersand more. Working from your drawings or helping to customize aspecific solution, our experienced team can take the appropriatecomponents and sub-assemblies and package completedindustrial equipment for delivery anywhere in the world.

Housing everything needed to complete our customers requirements

from start to finish, PSBs 350,000 square-foot facility includes:three covered and two outside loading docks, 20 functional pro-duction bays with overhead-crane lifting capabilities in each, sixmultimedia blasting booths, ventilated and heated paint booths,control panel shop and 60,000 square feet of warehouse space.

PSBs formal Quality Assurance program is designed to maintainthe high standards required by the many customers served byGeneral Air, including the following industries:

REGENERATION OPTIONS

X External/Separate SourceWhen customer has dry, cleanregeneration gas available.

A Split StreamA portion of process is split off, usedto regenerate bed, then returned toprocess.

C Atmospheric AirTypically known as blower purge anduses ambient air for regeneration.

E Closed LoopA captive volume of gas is recirculatedto heat and cool the regenerating tower.

Deliquescent Desiccant Dryers canbe installed indoors or outdoors, onsystems equipped with aftercoolers.They are highly efficient at lower inlettemperatures. At inlettemperatures up to

100F, a 20-30Fdew point temper-ature suppressionis attained.

Specialized Dryer Products

Tank Vent Air DryersThe General Air Storage Tank VentDryers are designed to reduce thewater content of air entering a liquidstorage tank, thusdecreasing internal

corrosion andentrained water.These dryers work onthe same principles asGeneral Air DesiccantDryers with the excep-tion that they aredesigned to efficientlydry air at atmosphericor near atmosphericconditions. Carbon orstainless steel constructionis available.

Oilsorber

The General Air Oilsorber utilizesa bed of activated alumina and/orcarbon to remove vapor phase oilthrough the adsorption process.The Oilsorber will

remove vaporphase oil enteringan adsorbent beddryer and prolongdesiccant life.

The General Air Mini-Adsorber is theequivalent to a compact single-towerdesiccant dryer. This type of systemis designed to dry smallvolumes of compressedair for point-of-useapplications. TheGeneral Air Mini-

Adsorber design

provides full bedadsorption. Inlet air flowis directed to the bottomof the canister, thususing the entire desic-cant bed for upflow dry-ing. Available adsorbers are: Activated alumina Molecular sieve Activated carbon

Drain Valves

ET-4 Electronically-Timed, Motor-Operated Ball-Drain ValvesNEMA 4X weatherproof enclosurefor indoor and outdoor installation.Switches for adjusting the blow-down cycle and the valve-open time.

A manual-override switch is equippedfor manually checking the ball valve.These drain valves are available in 1/2",3/4" and 1" NPT connections, carbon

steel, and stainless steel ball valvesare available. The drain valves operateat 115 VAC, single phase, 50-60cycles. This valve is a non-clogging,highly dependable drain used forreceiver tanks, sumps, coalescingfilter drains and refrigerated dryers.

Air andGas FiltersGeneral Airs efficient Filter units, withreplaceable cartridges, are availableas Particulate filters, Coalescingfilters, or as Odorgard/Adsorbentfilters. The Particulatefilter removes 100% ofall solids 0.9 micron andlarger. The Coalescingfilter removes all parti-

cles and all aerosolsdown to 0.3 microns.The Odorgard adsor-bent filter removes oiland hydrocarbon vaporsdown to 0.001 ppm inaddition to eliminatingoffensive odors affectingtaste and smell.
