R912- Reiff Rotax 912/914 PREHEAT KIT – 250 Watt

Description

The standard system is 250 watts and includes two 100w HotStrip heater epoxied to the bottom of the crankcase, and a 50w HotBand clamped around the oil tank. A thermostat bonded to the oil tank limits the oil temp to about 190°F.  (220 volt systems also available by phone order only.)

The Light Sport Aircraft (LSA) industry has been gathering momentum, and most of the LSA models use the Rotax 912. Although it is a good engine, it has 3 issues you should be aware of:

• It does not start well in cold weather because the electronic ignition system will not fire the spark plugs unless the starter cranks the engine at a crankshaft speed of 220 rpm or more (90 rpm propeller speed). A cold engine is stiff and a cold battery is weak, so the starter may not be able to crank the engine fast enough to start it.
• A slow cranking speed can cause kickback, which damages the spring clutch.
• If the engine does start, you cannot do the run-up or take off until the oil reaches 120°F (48.9°C). This may require a lengthy warm-up period.
  See your Rotax Operating Manual for more information.

The above 3 problems are solved by preheating the engine.
Our system has proven to be a convenient and inexpensive means to do this, and we have been selling a lot of them.
The system is installed on your engine so all you need to do is plug it in to a wall outlet with an extension cord for a few hours. Overnight is best. Throw a blanket over the cowling to seal and insulate the engine compartment. The engine will think it’s summer time and will start easily, and because the oil is preheated you will not need a long warm up period before you can do your run-up and takeoff.
