High pressure heating coil:

We are using a heavy schedule 80 black iron coil for all the dealer units, we have found that the schedule 40 while being much cheaper will only last so long with the larger pressures.

So no matter which unit you buy it will indeed have the heavy schedule 80 coil with the stainless steel coil wrap for much longer life.

We have found by experience that the coil is usually one of the last things standing.

Warnings for the cold climates; these will freeze and bust so be aware of this in the winter climates that get below freezing. Just make sure the coil has had some antifreeze sucked through it before storage and drained before the next use. This is an easy process that we will explain to you if needed.
