An indispensable tool for more than 7,500 crop dusters in operation today, the Crophawk® sets the standard in accurate chemical flow measurement.

One of the most critical tasks for the aerial applicator is to apply accurate quantities of chemicals to the field. However, there's no such thing as precise estimation. That's why we designed a product that puts an end to the guessing game.

The Crophawk Flow Monitoring System is designed to provide the ag-aircraft pilot with accurate chemical flow data. The system measures chemical as it flows from the tank to the spray boom and indicates the chemical flow rate on the cockpit display.

A wide variety of display channels are available. We're proud that the Crophawk has set new standards for accuracy and cost effective technology in the industry, and we'd like to tell you about our latest advance, the Crophawk Model 7/B

Surety Online Mapping has nation wide coverage of all current 2006 NAIP imagery and FSA field borders. Surety allows aerial applicators to select or custom create field borders to be downloaded as a shape file in a fast and easy method. Aerial applicators are also able to print aerial maps and application reports with this system. These options allow the applicator to easily identify application fields and know the exact locations to the center of the field with GPS coordinates. Fly straight line to your field!. Save time!

How does it work?

The TANIS system brings the entire engine up to a safe operating temperature by:

1. Heating the cylinder heads.

Heat is applied at each cylinder head using either thermocouple well heaters, extruded block heaters, intake bolt heaters, or rocker gasket heaters.

2. Applying heat to other critical points in the engine.

Additionally, a hot plug at the intake oil screen, a thermal pad, a hot oil drain plug, or a sump gasket heater may also be used.

3. Avoiding over heating the oil sump. which can "decrease the performance of the oil". (Ben Visser Aeroshel, Oct. 97 AOPA Pilot )

The Tanis system applies only a very moderate amount of heat to the oil sump as an aid in heating the entire engine rather than for the purpose of heating the oil.

The Tanis preheat system is safe, reliable, easy to install and most of all, it is a preheat system that provides you with an investment that you will not regret later!

Blades are molded from tough composite material and mounted with roller type thrust bearings. All steel parts are plated. Blade pitch is controlled through a push-button type vernier control cable. Blade design attains high power input to the pump. Adapts to most pumps and aircraft in use today. Requires removal of present fan and brake assembly, plus the drilling and tapping of a retainer cap screw hole in the end of the pump shaft. The control cable is installed according to individual desires but must be securely mounted. Blade full feather instantly to stop the pump. No brake is required. In the feathered position, drag is cut approximately in half as compared to standard plastic multiblade or wooden fans. Fuel savings will eventually pay for the fan.
