Anti Idle Technology - Has anybody have expiriance with SIGMA?

[yuvalk]

Hello fellas

I would like to know if anybody of you heard about SIGMA company which offers to reduce fuel costs by shut down engine and turning on DC air conditioner system that cool down cabin for operators on heavy duty machinery while machines is idling more than addition time.
My big concern is the wear of the starter motors because of multiple starters that will accrue more often with this kind of system.
I have question for you guys –
So, if anyone of you ever heard about SIGMA?
I you do please share with me your experience…
If you didn’t heard about SIGMA – what do you think about my concern? Is it justified?

I attached PDF file which explain more about that Anti-Idling system

Many thanks for your replies
