Flexitech offers the latest technology of defrosters. The defrosters are designed to prevent frosting and fogging of Optical Windows, Filters, and Lenses. It helps providing crisp and clear image at all times and weather conditions.

The defrosters are suitable for a wide variety of glass and glass-ceramic elements (perfectly compliments silicon, sapphire or germanium elements).

Suited to many applications, including Defense, Automotive, Agriculture, Laser, and Airborne Systems.

Challenge us to engineer the perfect solution to your fogging and icing issues.


  • Easy assembly process
  • High thermal conductivity
  • Low Thermal Coefficient of Expansion (TCE)
  • Straight forward temperature control
  • Quick temperature ramp up and cool down
  • Withstands both low and high temperatures
  • Resistance to power surges
  • Can be cut to any shape

Comparison with other solutions

Current defrosting solutions available in the market, such as ITO (or transparent heater), polyimide flexible heaters and thermal blower, offer only a partial solution to prevent windows from fogging or icing in harsh environments.

See our comparison table and understand how our innovative ring-shaped defroster can provide you the full solution that will maintain the designated temperature, avoiding a blurry image.
