About Maxi-Therm

The company

Maxi-therm was founded in 2004 and is today a 65% owned Canadian and 35% owned American company with manufacturing facilities in the U.S. and Canada.

All major components including vertical heat exchangers, control valves, pumps and accessories are manufactured in the United States.

We proudly manufacture High Efficiency steam to liquid vertical flooded concept for building heat and for domestic use transferring not only latent heat of steam but also sensible heat of steam in a 0% flash return system even at high pressure steam such as 175 psig and considering super-heated steam.

The objectives

  • NO steam pressure reducing station and NO steam safety to roof even @ 175 psig steam
  • NO condensate return sub-station, NO flash tank, since condensate is subcooled to 200F or less, 0% Flash return

The advantages

  • Energy savings average of 8%
  • Initial installation cost reduction 20% Learn more
  • Space saving up to 40%, in a vertical concept Learn more
  • Stability of set point temperature ± 2°F

The Ultimate Package Solution

Including circulating pumps, air separator, control panel, piping, saves time in engineering and can easily be piped to only 4 connections:

  • Steam IN
  • Condendate OUT
  • Cold liquid-IN/hot liquid OUT

Maxi-Therm factory mounted and pre-wired control panel allows a continuous supervision and modification of the parameters by the building automation system. Troubleshooting is accomplished remotely by the factory via Internet using an Ethernet connection.

The seminar of October was another very interesting experience with 19 guests. It was a real pleasure having you all in our lab for two days.



The seminar of September was a success with 14 attendees. Here is one of the comments received:
"I would like to thank everyone at Maxi-Therm for the opportunity to attend your Montreal seminar September 20thand 21st 2012. I found the information covered by you and Gabriel Cossette in the subject of steam management extremely educational and insightful. The expertise and professionalism conducted during the class is among the very best and dialog between colleges was extremely informative. In my opinion system’s created at Maxi-Therm are innovative and cutting edge. As for the hospitality, it is world class and has left me knowing that the people at Maxi-Therm are not only at the top of their profession, but they are also the top among hosts. Thank you once again."



Maxi-Therm inc. is today a 35% American owned company and has 4 new shareholders:three American silent partners and Gabriel Cossette, Eng. from Maxi-Therm inc. (Qc)



Maxi-Therm inc. introduced a heat exchange package (patent pending) to control «QUALITY STEAM» for sterilization and humification, quality steam has been determined to be @ 97% saturated or greater (i.e. less than 3% of the mixture mass is liquid.)
