KW x 1000  ÷ 1.73 = Amps 3 F
    Volts

KW x 1000  = Amps 1 F
   Volts

Example:

150 KW at 480 V 3 F.

    150 X  1000
    _______________  ÷ 1.73 = 54 Total Amp Draw
          480
    180     ÷ 48 Amps max circuit rating = 3.75
    Round up the numbers of circuits to 4

Note:
Each branch circuit is rated at a maximum of 48 Amps and each circuit is typically operated as an independent temperature step.

Model SH And H Sizing Information

 Step 1 

Solve for the unknown using the formulas stated below.
Variables To Solve For:

1. KW Requirement:

    __________GPH x __________ oFDT x 0.00244 = __________ KW

2. Temperature Rise:

     __________   KW x 410 ÷ __________ GPH = __________oFDT

3. Flow Rate:

     __________   KW x 410 ÷ __________ oFDT = __________ GPH

Metric Conversions

Liters x 0.2641 = Gallons
Gallons x 3.79 = Liters
Gallons x 0.003785 = m3
m3 x 264.2 = Gallons
1oC DT = 1.8oF DT
oF = (oC x 1.8) + 32
oC = (oF - 32) x 0.556
psi x 0.06896 = Bar
Bar x 14.5 = psi
psi x 6.86 = kPa
kPa x 0.1456 = psi
Lbs x 0.4536 = Kg
Kg x 2.2 = Lbs
Watts/Sq.Cm. x 6.4 = Watts/Sq.In.
Watts/Sq.In. x 0.155 = Watts/Sq.Cm.
