Icegard

Icegard is ideal for a wide range of applications for frost protection, industry, farming, food production to name a few. In fact Icegard is ideal for any application that requires a constant flow of water, without the threat of freezing pipes.

Heating Zones

Technical Description

Infroheat's electric heating tape is a parallel circuit tape heater producing a continuous series of heating zones, each approximately 1 metre long, thus providing a constant watts per metre along the entire length.

Though the tape may be terminated at any point, we recommend that the tape be terminated just past a connecting joint, thus minimising any cold zone.

Choosing the Infroheat tape for your application

To assist you in selecting the correct tape for your requirements, follow these guide lines:

i) Establish the pipe size, required operating temperature and the lowest ambient temperature.
ii) Calculate the difference between the required temperature and the lowest ambient temperature (∆T).
Multiply by the relevant factor from table 2.

Example

Pipe size = 2 inch
Insulation thickness = 25 mm
Lowest expected temperature = - 10° C
Operating temperature required = + 5° C
deltaT = 5° C - (-10° C) = 15° C

Multiply factor for 2" pipe from table 2 is 0.57
Heat loss per metre of pipe = 15 x 0.57 = 8.55 W/M
So the suitable tape for the above application will be ICEGARD IHP10/230, straight traced along the pipe.
