 Posted: Thu Feb 11, 2010 3:48 am Post subject: Oil Thermostat - X-Air's new version |
 |
|
I know there has been some discussion about oil thermostats recently on the forum. This new one from X-Air appears smaller/lighter than the automotive version I've seen in the past.
Beyond that, I have no further info/experience.
Cheers,

Every now and again something new comes along which stops you in your tracks because it is just such a good idea and a unique product.
I have just come across one of these products and it's a specially designed thermostat system designed to regulate the oil temperature on engines like the Rotax and Jabiru.

We are all aware of the damage which can be caused by running your aircraft engine oil temperature too low, in fact it has always been recommended to get the oil temperature just over 100°C during each flight to burn off the water which can contaminate the engine oil, if you are flying time and time again and the engine temperature is only getting to say 85°C the water will remain in your oil as a contaminant and can go on to destroy your engine with corrosion problems. Additionally, warmup is achieved very quickly on even the coldest of days because the thermostat diverts the oil flow from the oil cooler.
Made in the USA these special oil thermostat units are designed to quickly allow your engine to reach and maintain its optimum operating temperature even on the coldest of days.
CNC machined from 6061-T6 the unit is anodised with the type 2 surface finish to protect the thermostat long-term against corrosion. All of the hardware is aircraft grade and the oil thermostat unit is finished to the highest possible standards and is supplied with hose nipples to fit the most common oil tubing diameter used by Rotax and Jabiru.
There are a number of benefits in using an oil thermostat in your aircraft which include fuel savings resulting from quick warmup times and engine operation at optimum oil temperature which also increases engine life because the engine is being operated at the correct oil temperature.
Stage 1
Cold oil: the internal oil bypass is open, allowing incoming oil to bypass the oil cooler and returned directly to the engine significantly reducing warmup time. [img]cid:015522113(at)11022010-2887[/img]
Stage 2
As the oil reaches the desired operating temperature the internal bypass partially closes, automatically regulating and controlling flow through both the internal bypass AND the external oil cooler so that desired operating temperature is maintained. [img]cid:015522113(at)11022010-288E[/img]
Stage 3
Hot oil: the internal bypass closes completely, directing 98% of the total oil flow through the oil cooler. Under these conditions, the all temperature is limited by the cooling capacity of the external oil cooler. [img]cid:015522113(at)11022010-2895[/img]
I have been asked the same questions by most of the people I have shown this thermostat unit to...
Will it reduce my oil pressure? The simple answer is no installing an oil temperature thermostat may slightly increase your oil pressure when it is most needed during cold starts. It offers a shorter, less restrictive flow path to the lubricating oil while the engine is cold. The cold oil bypasses the oil cooler and eliminating the small pressure drop that would otherwise occur.
Can it block the flow of oil? No, it cannot block the flow of oil in any circumstances whether operating normally or in a failed condition, it is impossible for the unit to block the flow of oil or the oil circuit.
What is the warranty period? The warranty period of the oil thermostat is two years.
How big is the unit? The unit is really small being 55mm high, 55mm long (without the hose barbs) and just 40mm deep, the unit can be bolted to the firewall or a bracket with the two 3/16" mounting holes.
Most important... The Cost? The cost of the oil thermostat with oil hose nipples is only $200 AU$ plug GST and delivery.

This is a very nicely made thermostat. but quite expensive. ConAir have decided to market it in the UK.
I am just finishing off the Standard Mod application to the LAA for both this and the Permacool. The Permacool is a lot cheaper.
