car wash

Mark Eatherton

And the tank is the fill/compression tank. In some cases, that tank may be pressurized, but have seen them both open and closed.

It also appears that it has automotive grade (Green) antifreeze, which is considered toxic.

The real unfortunate thing is that the set up probably runs most of the winter. Most car wash snow/ice melt systems operate based on OSA. When it gets below 40 degrees, its off and running. And with the modutrol, the appliance spends the majority of its time operating with extreme excess air (due to burner modulation) which causes it to have an efficiency around 40 to 50%.

If you really want to save them operating cost, replace it with a good modcon boiler.

This is a snow melt system for a car wash. It's the first one I've worked on. The Raypak boiler had a honeywell valve of some sort after the gas valve V5155A2407.

If you find out what the function of that tank with the sight glass is, let me know. RayPac won't call back with the info and have not returned several phone calls. E-mail me direct with the answer please.

on the jacketing behind the gas valve. Often this indicated the HX is getting plugged and the fins need to be cleaned out, ( a messy , toxic, job wear a respirator) With out mixing and return protection that boiler probably spends some time in the condensing mode.

They also suck all the chemical fumes, soap, etc from the room. adding to the coil HX concerns.

A good, well sealed mod con would do wonders for that job. A simple air stat in the bay can reduce run time if a snow and ice sensor is not n option.
