Steam has become a vital tool in hospitals, factories, campus colleges, and many industries. It is primarily used for humidification, sterilization, building heat and domestic hot water. It has become a reliable energy that is easy and safe to transport and therefore it is used in cities around the world, like New-York, Boston, Seattle, Montreal, Richmond, etc. However, in over a hundred years the design of the steam heat exchanger has not changed, until now.

A new steam heat exchanger has been launched that removes the need for all the components the old design has. The new design brings the steam heat exchanger into the modern world and makes it more efficient. The new steam heat exchanger from Maxi-Therm in Montreal has been hailed as bringing a new and improved design.

Engineers, mechanical contractors and building maintenance managers come across steam heating systems in their line of work. They may have noticed that the design of the steam heat exchanger has not changed in the last 100 years. One of the problems with the old design is the number of components it needs. That includes 2 (1/3-2/3) pressure reducing valve and 2 (1/3-2/3) control valve on the steam heat exchanger. A steam safety relief valve pipe to the roof, which needs yearly maintenance. A dedicated 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.

The new steam heat exchanger from Maxi-Therm means no more pressure reducing valve, no more condensate pump and no more safety relief valve. It offers an innovative vertical flooded steam heat exchanger solution that not only avoid all those components but brings energy savings up to 15%.

The concept consists 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 that is not possible when professionals 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.

A spokesman for Maxi-Therm explained why it doesn’t need a safety valve, “Maxi-Therm provide an ASME (CRN for Canada) stamp for high-pressure vessel on the steam heat exchanger and the complete package.  This way the safety valve is not needed.”

With over 400 installations around the United States and Canada, this unique concept is the new talk in town for the steam user or designer.  They have multiple representation around North-America: Boston, Seattle, Chicago, Denver, Washington DC, New-York, Richmond, Vancouver, Cleveland, Philadelphia and more.

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 to avoid multiple condensate return lines.  They simply offer all the solutions to have a 100% close loop on steam and condensate network.  No one had offered those type of solutions before.
