able Design for Pipes
Step 1 - Heater Design Determine heater design to use. Design D is usually the most convenient design using two conductor cable.
Step 2 - Heat Loss(W/M) Use the value calculated from Technical section- Heat Loss Calculations, Pipe & Tank Tracing.
Step 3 - Cable Length (L) Use the length calculated from Application & Selections Guidelines in this section.
Step 4 - Supply Voltage Available (V) Determine what voltage is available. When different voltages are available, it provides multiple cable choices which may result in a more accurate design.
Step 5 - Calculate Resistance per Meter(R/M)
Step 6 - Select the Meter(R/M) Rating Choose a cable having equal or the next lower resistance per Meter value from Ordering Information Table, next page
Step 7 - Calculate Actual W/M. and total wattage (W)
Step 8 - Determine Current Draw(I)
Step 9 - select Heater Single or Double Conductor Cold Lead Length The cold lead length is determined by the customer or by using a nominal 1.0 Meter. All cold leads are 6.0～8.0mm WG with 40 Amp maximum current capacity
Step 10 - Convert Design to a Model Number
Or dering Information
To Order-Complete the Model Number using the Matrix provided. If applicable,specify
