Flexitech offers the latest technology of defrosters. The defrosters are designed to prevent frosting and glossing on surveillance cameras, keeping them active and providing crisp and clear image at all times and weather conditions. Also, they are set to prevent condensation and ice build-up on a camera lens.

Flexitech‘s defrosters provide a comprehensive and innovative solution to the current defrosting solutions in the market:

  1. Thermal blower – featuring complicated construction and low reliability
  2. Transparent heater – causes reduced transparency, based on complex manufacturing, assembly and logistics process while presents difficulties in temperature control.
  3. Flexible heater – Polyimide flexible heaters: high requirements for bonding, limited temperature range and power density.

To provide their effect, Flexitech‘s defrosters are utilizing special heaters, turning them much more efficient and long lasting. The defrosters offer all the advantages required today from such a component:

  • Easy assembly process.
  • Simplicity in temperature control.
  • High reliability.
  • Withstands low and high temperatures and overloads.
  • Low requirements to the quality of gluing.
  • Provided with two-sided glue.

 

The advanced defrosters are being used by leading organizations, looking to achieve top viewing performance in their surveillance cameras.
