PHC Parallel Heating Cable
︳ Purpose
Keep warm onto the fluid of inside tube ,tank by heating to prevent freezing.
Electric heating bed for the greenhouse seedling cultivation.
︳ Features
Every 0.5 meters to 0.7 meters, weld heating wire and power lines individually form a continuous parallel heating cable.
Every intervals of heating load were independent , even though a section of load broke it will not cause the entire thermal zone to fail.
The maximum load 1000W under a thermocontroller ,cutting the length of PHL as required from 1 meter to 100 meters.
Standard load 40W / m , 30W / m ,20W / m ,10W / m of four versions.
︳ Application (1)
Name：Measured the temperature of PHC which be wrapped outside around the pipe.
Function：Chose the different load of PHC for keeping warm onto the fluid of inside pipe.
Test conditions：
Iron pipe with outside diameter 22 × inside diameter 19 (mm).
Iron pipe surface wrapped up aluminum foil tape.
Iron pipe sealed at both ends.
The measured temperature (reference value)：
︳ Application (2)
Name：The PHC for heating water.
Function：liquid heating.
Test conditions：
2 liter vessel.
PHC with 40W /Meter × 2.5 Meter = 100W.
Room temperature 30 ℃.
The measured temperature (reference value)：
Increased 18 ℃ after 30 minutes heating.
Increased 29 ℃ after 60 minutes heating.
Increased 35 ℃ after 90 minutes heating.
︳ Application (3)
Electric heating bed for greenhouse seedling cultivation.
