PATTERSON.KELLEY'S
FULLY PACKAGED HEATER
In the late 1950s, Patlerson-Kelley
developed the first line of completely
packaged commercialindustrial water
heaters. The P-K COMPACT semiinslantaneous
water heater was part ol
that nelv concepl when it was introduced
back then. Over the years, improvemenis
t0 the heatels design have represented
a continuing evolution of the original
concept, The P-K Col/PACT has always
been completely assembled at our facility
and, since it requires only four piping
conneclions, is shipped ready for
easy installation.
HISTORY OF PERFOBMANCE
P-K CoMPACT water healers have pedormed reliably, provlding
long, lroublejree operation in thousands of installations in all types
of commercial, institutiona and industria burldings as wel as on
Navy ships, lts present design, which locuses on a small heater that
produces high hot waler outpul at a closely controlled ternperature,
makes it the deal waler heater for any building owner.
HIGH.OUTPUT HEATER
Operaling on steam, boiler water or high-temperalure waler,
the P-K COI/PACT produces up lo 250 gpm at 40"F to 140"F,
Though the largest unit has a footprint oionly I sq. fl,, the heater
can handle any building's water heating requirements, either singly
or via multiple-unil installation.
PRECISE TEMPERATURE CONTBOL
The heater leatures P-K's unique AnticipatoP control, which
conlinuously meters heating rnedium demand 10 exacl proportions
oJ hgl watqr requirements and regulates the hol water outlet
temperalure lo a close tolerance of l4'F of set point, even wilh
sudden fluctuating draws,
PREVENTS SCALE
Constantly pumped circulation prevenls scale lormation and
accumulation 0f loreign matter on the heating surlaces in most
waler conditions (water soltening may be required with extremely
hard wate0. The constant ctrculation also continually monitors
water temperature, slabilizing temperature contlol at all draw rates.
CONSTRUCTED FOR LONG SERVICE LIFE
The P-K CoMPACT is built to last. Potable water in the she I
contacls only nonlerrous materials, preventing rusty water. The
shell is constructed 0fsolid 90-10 copper nickel, the premium
corrosion-resistanl material lor potable water service, Standard
heat exchanger conslructi0n is copper tubing, wh ch will handle
most water conditions. Coooer nickel is available for unusual
waler conditions.

TEMPERATURE.LIMIT SYSTEM
The P-K CoMPACT water heater is protected by a double
solenoid temperaturelimit system with a hot waler dump valve.
Should any overheating of water occur, the temperature-limit system
immediately kicks in to shut otfthe heat source and dump overheated
water into the drain. The valve controlling the heat source shuts off
until normal hot water temperature is reslored; tl'te unit then assumes
normal operating conditions. optional alarm and/or dry conlacl relay
is available for remote service.
NO OVERHEAD CLEARANCE
The P-K CoMPACT is the easiest lo service ol the semi
instantaneous water healers on the market today. The shell
always remains in place, so no overhead clearance is required
ior service. The tubesheets have drilled and taooed bolt holes for
independent bolting, enabling the bonnet lo be removed wilhout
breaking the domeslic water gaskets, ll a tube were to leak, il
could easily be plugged off as a temporary fix and the unit put
back into service within an hour, The steam or water chamber
is easily removed without dislurbing the piping to the unit, and
there is ready access to the tube bundle.
DOUBLE WALL DESIGN
The P-K CoMPACT is also available with a vented double.wall
tube bundle with double tlbesheets. This design offers the ultimate
protection againsl cross-contamination of potable waler and meets
both health department and building codes. The P-K double-wall tube
design creates maximum contact belween inner and outer tubes lo
produce effective heat transfer, while providing a venled leak path
as a visual means to indicate tube failure. The double.wall heat
exchanger can be installed in any existing P-K CoIVPACT water
heater originally supplied wilh single-wall tubing. Contact the
factory or your local P-K representative t0 obtain further
information, including lhe new rating.
A.S.M.E, CONSTRUCTION
The P-K CoMPACT water heater is corstructed in accordance with
A.S.[/.E. Code, Section Vlll, Div. 1, and comes with an insurance
company certificate ol inspection and test.

ANTICIPATOFP CONTROLSYSTEM
PRODUCES CLOSE TEMPERATURE CONTROL
The P-K COMPACT features the
Anticipatop integral conlrol system
which meters the heating medium
demand to exact proportions of hot
',vater requirements and regulates hot
water outlet temperature to a close
lolerance ol t4"F from the setpoint,
This schematic shows the general
arrangement of the P-K COMPACT.
Steam passes through the tubes of
the heat exchanger bundle. The water
is rapidly heated as it is directed over
the tubes by segmental baffles inside
a cylindrical wrapper. Above the
wrapped tube bundle, minimum
storage volume is provided to give the
controls sufficient time to produce the
'close
tempenture control.

IEATURES/BENEFITS OF THE P,K COMPACT WATER HEATER
. High-quality design and conslruction assure reliable performance and long service life.
. A complete package |/vith only four piping connectons enables quick, easy inslallalion.
' Compact design saves valuable floor space and fits easily into position.
' High-capacity output: Up to 250 gpm at 40"F lo 140'F allows the heater 10 meel the
hot water requiremenls ol any buildlng.
. Performs equally well wilh steam, boiler water or high{emperature water.
' AnticipatoP lemperalure control regulates hot water outlel temperalufers t4oF.
' Constant circulation by the pump prevents scale formation and improves temperalure conlrol,
' All nonferrous conslruction on the water side prevents rusty water.
' Tube bundle drops down,,latd lrom the heater, so no overhead room s required for service.
' Double solenoid temperaturelimil system prevents overheated water from entering the
distribution system.
' Design meets seismic-resttaint requirements, making it earthquake resistant.
. Built to A.S,M.E. standaidsi meets code requirements.
. Double-wall design available; meets 8,O.C.A. and LA.P.l\.,1,0. code requirements.
. Heat-transfer rates verified by independent lesling agency, assuring thal the healer
will perform al rated capacity.

SIZING INSTRUCTIONS FOR THE P.K COMPACT
1. Determine tolal lixture units for all fixtures by using the Fixlure Capacity
Table and lollowing the example below.
2, Determine the demand gpm from lhe Hot Water Demand Curves below,
3. Select lhe orooer size heater from the Sieam to Waler or Boiler Water
10 Water Selection Tables on pages 10-13. For other capacilies, contact
your P-K representative or the factory.
SIZE SELECTION
Select a heater to heat 75 gpm olwater from 40"F 10 140"F with steam
in the line at 25 psig. From page 10 of the Seleclion Tables, selecl a size
PK08S to heat 80 gpm irom 40'F to 140'F.

CORRECTION FACTOR FOR WATER TEMPERATURE VARIATIONS
The Fixlure Capacity Table is based on consumption of 140"F
hol water using 40"F cold water to obtain 100'F mixed water at
the lixture. Any variation ol these standard lemperalures wil, affect
the hot water consumption.
To determine lhe effect on the size oflhe P-K COMPACT, use the
following procedurel
1. Determine heaier size lrom instructions above.
2, [/ultiply the gpm rating by the correclion factor from the
lollowing formula:
M-C . lV-40 = Correclion Faclor
H-C 100
Where: lvl = mixed lemperature al fixture, C = cold water temperature
and H = hol water temDerature from heater.
For example, if the heater determined above has a rating ol 75 gpm lrom
40"F to 140"F and the aclual cold water lemperature is 70"F:
100-70 . 100-40 = .71 Correction Faclor

. Therefore, ihe required gpm is: 75 x .71 = 54 gpm lrom 70"F to 140"F,
Your healer selection would be size PK06S, which has a raling of
55 gpm from 70"F to 140"F. In m0st cases, the heater will operate at
140"F and a mixed temperature of 100'F is salisfactory; however,
the cold waler supply may vary lrom job to job.
