Explosion Proof HVAC

(OP)
What vendors do you have experience with for Mid-Sized (15-20 ton) Roof Top package HVAC units that meet NEC Class 1 - Div 2 rating.  I need to upgrade 3 units and my experience is only with small wall mounted package units.

Thanks for the help!

RE: Explosion Proof HVAC

Isn't there some way to remote-drive the equipment so that the motors and controls are not in a C1/D2 zone?  Is there some sort of belt-drive and air-control logic that could work?  Not my area, but such approaches might qualify as intrinsically safe.
