Patent number: 10955145Abstract: The heat exchange system is for heating water from a water source and comprises first and second flooded heat exchangers that have steam sides that are each independently fed with steam, but water sides that are serially fed with water through the first heat exchanger then through the second heat exchanger. The system also comprises first and second control valves located at or downstream of subcooled condensate outlets of the first and second heat exchangers, first and second water temperature sensors at or downstream of the heated water outlets of the first and second heat exchangers, and a control device for receiving temperature data from the first and second water temperature sensors and for controlling the first and second control valves.Type: GrantFiled: February 27, 2018Date of Patent: March 23, 2021Assignee: MAXI-THERME INC.Inventors: Raymond Lach, Gabriel Cossette-Labrosse, Patrick Lach

Patent number: 9920996Abstract: The system and method of controlling a level of flooding to remain substantially constant within a flooded heat exchanger wherein steam flows into a steam side and condenses to form condensate that partly floods the steam side and that flows out of the steam side, and wherein cold water flows into a water side in heat exchange relationship with the steam side to heat the cold water and form heated water that flows out of the water side, comprises collecting the water condensate flowing out of the heat exchanger condensate outlet into a level controller through a controller condensate inlet; connecting the level controller to a steam source having a pressure equivalent to that of the heat exchanger steam side; and controlling the level of condensate in the level controller to remain substantially constant with a controller valve that allows condensate to be exhausted out through a controller condensate outlet if the level of the condensate in the level controller rises beyond a valve activation threshold whereType: GrantFiled: February 26, 2015Date of Patent: March 20, 2018Assignee: MAXI-THERME INC.Inventor: Raymond Lach

Patent number: 7093566Abstract: A vapor generator comprising an evaporator unit, which in turn includes an inner chamber for containing a first fluid in a liquid state, and further includes a preheated liquid inlet and a vapor outlet, the evaporator unit having a heating device therein which can be activated for vaporizing the first fluid contained in the inner chamber to generate vapor. The vapor generator further comprises a preheating tank defining an inner chamber and comprising a liquid inlet for injection of the first fluid in a liquid state in the inner chamber, and a liquid outlet. Moreover, the vapor generator comprises an opened liquid channel connecting the preheating tank liquid outlet to the evaporator unit liquid inlet, and establishing free and continuous fluid communication between the preheating tank inner chamber and the evaporator unit inner chamber.Type: GrantFiled: November 12, 2004Date of Patent: August 22, 2006Assignee: Maxitherm Inc.Inventor: Raymond Lach
