12v dc heater electric water heater

12v dc heater electric water heater         Detailed Description Immersion heaters are one of the most widely used methods for heating liquids (such as water, oil, heat transfer fluid and corrosive solutions). Designed for use in tanks and pressurized vessels, they are easy to install and maintain to provide heat for many processes. The direct immersion method is energy efficient and easily monitored and controlled.      Features 1.HI-POT TEST: 1500V/S min cold condition. 2.Insulation resistance:20M Ω min   3.Leakage current to be 0.75ma max While energized at rated voltage 4.Power tolerance:+5%,-10% 5.Voltage:12V-440V 6.Diameter range:1mm to 40mm 7.Heating resistance wire:0Cr25Al5,Cr20Ni80 or as custom's requirement   Air tubular heater wattage : ≥ 2w-4w/cm2 Water tubular heater wattage: ≥ 6w-10w/cm2 Dies and fin tubular heater: ≥ 8W-12w/cm2
