Thread: This looks like a good AC system...

Chuck at Haultech put me onto the RedDot AC systems... They certainly look the goods.

I believe they are a completely self contained system, apart from the compressor. So it is simply a matter of curring a hole in the roof and attaching it, running a few hoses and cables, and gassing it up.

What do people think???

For heavy-, medium- and light-duty trucks, construction and agricultural cabs

The R-6100 is the ultimate rooftop air conditioner design. Red Dot went the extra mile in designing a lightweight, high-capacity unit with a styled low profile that fits the aerodynamic truck designs of today. A sloping front rides comfortably over center marker lights. This is a must when roof space is minimal or air shields are used.

A low-profile plenum protrudes barely 1.5 inches into the cab and blends easily into the headliner, leaving ample headroom. Frigid, high-velocity air can be directed 360 degrees through the large diffusers located directly below the double blowers. Also featured is a cab air filter incorporated into the plenum.

The heavy-duty design contains tube and fin coil construction, high-capacity receiver drier and Red Dot Trinary System protection switch. The Trinary switch extends condenser motor life and guards against component failure. Should the R-6100 ever need service, only two outside bolts need be removed to access any component. The R-6100 is perfect for most truck applications, especially COE's where space in the cab is limited.

Red Dot's Product Line

Yeah, Ben, I can recommend RedDot, they are really robust, and give reliable service. Mine runs on the standard NipponDenso compressor. The only thing I have had to replace once, is the fan switch, which handles a bit of current. From memory mines a 27000btu unit. Great 'cause the County has plenty of compulsory external ventilation.........If I went for it again, I'd get the aircond/heater unit, would've been handy up the snowies last year.
