Keep warm onto the fluid of inside tube ,tank by heating to prevent freezing.   2. Electric heating bed for the greenhouse seedling cultivation. ●Features： 1. Every 0.5 meters to 0.7 meters, weld heating wire and power lines individually form a continuous parallel heating cable.   2. Every intervals of heating load were independent , even though a section of load broke it will not cause the entire thermal zone to fail.   3. The maximum load 1000W under a thermocontroller ,cutting the length of PHL as required from 1 meter to 100 meters.   4. 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： 1. Iron pipe with outside diameter 22 × inside diameter 19 ﹝mm﹞.   2. Iron pipe surface wrapped up aluminum foil tape.   3. Iron pipe sealed at both ends. ●The measured temperature ﹝reference value﹞： Watts ﹝W/m﹞ The surface temperature of Iron pipe ﹝℃﹞ The internal temperature of Iron pipe ﹝℃﹞ Room temperature ﹝℃﹞ 40 80 100 25 30 68 83 25 20 48 58 25 10 42 48 25 Application ﹝2﹞   ●Name： The PHC for heating water. ●Function： liquid heating. ●Test conditions： 1. 2 liter vessel.   2. PHC with 40W /Meter × 2.5 Meter = 100W.   3. 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. Parallel Heating Cable DM Download
