Hi guys I have a Prochem 650 HP Truckmount machine with 7500 hours on it. There a 3 separate units inside the main heating unit. 2 are high pressure stainless steel heat exchangers and 1 low pressure copper exchanger. The maintenance manual says to get in there and clean off debris every 1,000 hours....

I have never cleaned them and now they have cracked/rusted apart and have water coming out of the exhaust. So I have ordered 3 new heat exchangers and waiting for them to come in.

So my question is, I have heard of guys removing those flimsy metal fins (much like the screen of a radiator) off the exchangers to
A: reduce the amount of debris that get build up on them.
B: improve airflow and reduce back pressure on the blower.

I know those little fins are designed to help capture heat and is designed like that for the machine, but there is no shortage of heat on that machine. Just wanted to see what your thoughts were about this?
Thank You!

I have no idea but I would assume your van would be a lot hotter inside if the heat is displaced in your van and not the heat exchanger. Those little fins are a big deal to HVAC guys when they plead how important it is to keep those things clean on your outside units. Plus they offer other protection that we are unaware of.

Lars do not alter your hx's. You got 7500 hrs with no maintenance. Every 1000-1500 hrs. is like once a year or 1 1/2 year of cleaning. Do it with a shop vac. when its slow season. You may void your 1 million hr. warranty. lol. Don't forget to clean your dishwasher and refrigerator fins.

Thanks! Original engine, change oil every 200 hours. On my 3rd blower unfortunately... that trilobe blower has some issues I think... they changed over to something else on the newer models. Little disappointed in the blower issues, but still a great machine all and all

Interesting...our 650HP has 6,500 hours on it, haven't changed the blower yet. It's a 2012 model.

HX still original no cracks yet. We do soft water as well, but not on the truck, treated in the shop.

Sounds like it could be a hole in your heat exchangers. They are right behind the blower exhaust. How many hours do you have on it?
Its leaking over night. Then as I take my first left turn it all comes out of the exhaust. I have about 3'000 hrs on this machine.

Just a note about the blower. I replaced the blower on a 650 awhile back third one for him also. Here's what I found, that blower requires a special oil. Aeon PD XD or equivalent which the local distributor does not stock. They were using AEON PD. The difference in comparison is 0W40 vs 0W90 oil so make sure that you are using AEON PD XD (extreme duty)and your blower will last longer. been 6yrs since I replaced that blower.
