Our Carburettor Ice Detector Model 107AP is FAA and CAA approved and is specifically designed for aircraft with reciprocating engines equipped with a carburettor.

For years ARP’s Carburettor Ice Detectors have proven to be an effective "pre-ice" and "frost" formation warning system. It utilizes an ‘optical’ probe, which does not measure temperature, but detects actual ice build-up within the carburettor. This is extremely important when detecting carburettor ice, since ice formation varies over both humidity and temperature as shown in the enclosed Carburettor Icing Probability Chart. Frost/Ice crystals blocks the passage of the light emitted by the probe, thus triggering the instruments Red Warning Light. As soon as enough carburettor heat is applied to melt the frost/ice on the ‘optical’ probe within the venturi (adjacent to the throttle valve), the warning light extinguishes. If icing continues and the warning light illuminates again, you can use ARP’s Carburettor Ice Detector to monitor the minimum amount of heat needed to keep the light out, the carburettor frost free and the engine running economically and safely under existing icing conditions. In fact, Aviation Safety has written an article in their February 1998 issue discussing the problem of carb-ice and recommends that if your aircraft is not equipped with an ice detector already, that you should consider installing one.

Depending on your installation needs and available space, ARP offers the "Panel Mount" configuration for mounting in a standard 3-1/8" opening and the "Remote Mount" for aircraft limited panel space. The On/Off Switch and Sensitivity Knob on the Remote Mounted Unit are attached to the instrument itself and the Red Remote Warning Light separate, so it can be mounted in tight locations on your instrument panel or glare shield. Installation is minimal, requiring approximately 1 to 3 man-hours.

Each system is equipped with an ‘optical’ probe, and is accompanied with a detailed Aircraft Installation Manual, an Aircraft Flight Manual Supplement and a copy of the FAA Supplemental Type Certificate and is warranted for one full year.
