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% close loop on steam. No one offers those type of solutions before.

The Powerful Flushing Action, CleanCurve Rim and EverClean Surface of These High Efficiency Toilets Deliver the Cleanest Flush Ever Engineered

The revolutionary VorMax toilet line from American Standard has been named a 2015 GOOD DESIGN award recipient in the Bath category for design excellence. This award is presented by the Chicago Athenaeum Museum of Architecture and Design in cooperation with the European Centre for Architecture, Art, Design and Urban Studies.

Showcasing a classic composition suiting traditional bathroom settings, these innovative water-efficient toilets employ the unique VorMax flushing system, which has been independently verified to clean the bowl two times better than conventional toilets*. Eliminating the traditional tiny rim holes around the bowl that carry water during flushing, the VorMax flush delivers one powerful jet of water that scrubs the entire bowl completely clean.

These WaterSense-certified, high-efficiency toilets (HET)remove all splatter and clinging waste using only 1.28 gallons of water per flush (gpf). VorMax toilets feature a CleanCurve Rim that omits the rim overhang and holes inside the bowl where dirt and buildup can hide, and the brand-exclusive EverClean finish that inhibits the growth of stain and odor-causing bacteria, mold and mildew on the surface.

“We are thrilled and honored to accept this esteemed recognition from the Chicago Athenaeum for the cutting-edge, high-performance VorMax platform,” said Maha El Kharbotly, chief marketing officer of LIXIL Water Technology Americas, American Standard, DXV and GROHE. “American Standard has a 140-year history of leadership in improving the quality of everyday life for our customers. This legacy of developing stylish bath and kitchen products with progressive technologies like VorMax is reinforced by this revered design excellence award.”

GOOD DESIGN is the world’s oldest and most prestigious design programs. Each year, The Chicago Athenaeum presents the GOOD DESIGN Awards for the most innovative and cutting-edge industrial, product, and graphic designs produced around the world. One of the main factors for the awards selection is based on whether or not a product can enrich society and people’s lives through its design
