Innovative Vertical Flooded Steam Heat Exchanger

If you are an engineer, a mechanical contractor or a building maintenance manager you probably came across steam heating system. And you noticed that steam piping design as been done the same way for the last 100 years or so. The traditional way of design those steam network needs a lot of components like 2 (1/3-2/3) pressure reducing valve, 2 (1/3-2/3) control valve on the steam heat exchanger, steam safety relief valve pipe to the roof which need yearly maintenance and a dedicate condensate return pump with a vent pipe to the roof to eliminate all the flash in return condensate line in order to avoid any water hammer.

What if you can avoid all those components?

No more pressure reducing valve, no more condensate pump and no more safety relief valve.
Maxi-Therm base in Montreal Canada offer an innovative vertical flooded steam heat exchanger solution that not only avoid all those components but bring you energy savings up to 15%!
The concept consist of using a vertical heat exchanger with a small control valve install on the condensate return line. By doing so, they flood the heat exchanger. That allows them to extract not only the latent heat but also the sensible heat which you don’t do when you use a traditional horizontal heat exchanger system. And because they work on full pressure in the steam inlet, they don’t need a vacuum breaker, so they don’t inject oxygen in you return lines anymore.

Why they don’t need a safety valve?

Maxi-Therm provide an ASME (CRN for Canada) stamp for high pressure vessel on the heat exchanger and the complete package. This way the safety valve is not needed. With over 400 installations around United States and Canada this unique concept is the new talk in town for steam user or designer.

And the big question is why we didn’t do this before?

Well if you take a look at the traditional manufacturer in the steam business, not only they offer heat exchanger concepts but also all the components needed to make this work, so by pushing this type of concept (flooded steam heat exchanger) they will lose a lot of return business in maintenance over years.

Maxi-Therm is surely becoming the new leader in the steam world, not only they provide building heat and domestic hot water system but also a clean steam generator and a condensate mixer that avoid multiple condensate return lines. The simply offer all the solutions to have a 100% closed loop on steam. No one offers those type of solutions before.
