Product Description

High Voltage PTC Air Heaters – STW Type

UL, CSA approval, Customizable, and IP68 Compliant Heating Solutions

STW high voltage PTC heater UL

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!)

IP68 Compliant Heating Solutions with MHW, MSHW, SHW, THW and OHW heaters are available. Welcome to send us your inquiry for details.

Specification Range:

Voltage: 12V~999V (12V~600V with UL, CSA Approval)
Power: up to 30000W (maximum is dependent on size and design)
Minimum Size: 10mmx10mmx10mm
Maximum Size: 999mmx337.5mmx25mm
Thickness: 10mm/ 25mm

Key Features of the High Voltage PTC Air Heater STW

  • UL Standard High Voltage Insulation: Ensures safety and compliance with stringent industry standards.
  • Multi-Phase Control: Can be connected under a homogeneous load for optimal performance.
  • Customization: The STW heater offers extensive customization options in size to meet specific application requirements.
  • UL and CE Approved: Certified for both UL , CSA and CE standards, ensuring reliability and safety.
  • IP68 Compliant: While currently available only with wires, the heater can be certified by a third party for IP68 protection upon request, providing robust resistance to dust and water.
