Why Anti-Icing ?

Anti-icing equipment is a strategic component for avionic probes. It is designed to keep outer avionic sensors skin of Total air temperature probes and Pitot tubes free of ice while in flight. Our R&D and Engineering teams are working for the best anti-icing design to obtain the most efficient sensor and also the most reliability to fit with aircraft MTBF.

The THERMOCOAX’s anti-icing solution is innovative due to its self-regulated technology

We have a daily challenge to get the best cost/benefit ratio to make our customer competitive on the market.

Anti-Icing  for Total Air Temperature Sensor

Total Air Temperature (TAT) Sensor:

We produce TAT sensors fully equipped with anti-icing elements and also the anti-icing system separately when the customer self-manages the complete probe development and manufacturing. The THERMOCOAX’s anti-icing technology is based on true cold ends but the most important is the small anti-icing cable diameter for complex integration in the probe’s body.

 Key Parameters for Anti-Icing Probe

Range: -54°C up to +150°C
TAT Body: SS316, Inconel , Titatnium
Available with thermocouple class 1 or Platinum RTD class A
Single or dual element design for redundancy
Recovery Factor better than 0.96
Up to Mach 0.8

Robust housing for on-board application

Anti-icing system integrated in the tip of the probe
Self-regulation technology with Nickel or Balco

Qualification RTCA DO 160 -MIL

NIST calibration

Response time in wind tunnel up to Mach 0.6

Anti-Icing  for Pitot Tube Sensor

Static and Dynamic Pitot Tube Probe Sensor: 

The anti-icing heating cable is shaped around the dynamic and static air pipes. For a better conductivity and to withstand flying conditions, anti-icing cable and pipe are brazed together.

The power is defined as a function of the power supplied on the aircraft and the outer casing is designed to have a good anti-icing system.

Key parameters for anti-icing in pitot probe:

  • Built to customer's specification
  • Mineral Insulated cable manufactured in house
  • Self-Regulated
  • Nickel or Inconel sheath alloy
  • True cold end
  • Spiral design, twin cores

Example:

160 watt, less than155 volt 400Hz
MIL and/or RDO160-rated
HALT Tests
