Product Description
High Voltage PTC Air Heaters – STW Type
UL, CSA approval, Customizable, and IP Rating Waterproof Heating Solutions
A high voltage live part can be extremly dangerous (uninsulated high voltage is very dangerous) to work with, thus the launch of STW to provide UL standard high voltage insulation. Being electrically insulated, STW type heaters can be controlled with PWM and can allow 3 phase connection under homogeneous load. Although this heater requires external aids such as frames to be as mechanically durable as MH, MSH, SH, TH or OH heaters, this heater allows high customization in size and is UL and CE approved. Currently available only with wires, can be certified by 3rd party for IP68 upon request. (High voltage heaters with MH, MSH, SH, TH and OH heaters coming soon!)
Learn more about MH, MSH, SH, TH and OH heaters here.
IP68 compliant Waterproof Heating Solutions are available upon request, featuringMHW, MSHW, SHW, THW and OHW heaters designed for reliable performance in demanding environments. Feel free to send us your inquiry for more details!
