You may be wondering why you need a thermostasis unit for your Rotax 912 engine.
For those of us living in cold temperatures, this unit dramatically decreases warmup
times on your engine. In addition, it also really keeps the oil temperatures up
to a nice temperature on long low power descents. Here is some actual customer data
on an RV-12.
Temperature -2 Celsius on ground, -13 Celsius in flight
- Warmup time on ground from 60 to 122 degrees
- Without Thermostasis = 11 minutes
- With Thermostasis = 6 minutes
- Without Thermostasis temperature drop to 122 degrees in long reduced power descent
- With Thermostasis temperature around 200 degrees in long reduced power descent
- Cruise temperatures with thermostasis at -13 Celsius were in the 180-190 degree range.
