Abstract: Evaporator system used for the production of maple syrup. The evaporator system includes at least one receptacle, a combustion chamber, an evacuation port and an air supply system. The evaporator system also includes a door assembly being configured for removably mounting onto a corresponding support frame of the evaporator system, and being operable between an opened configuration for allowing access to the combustion chamber and to be able to selectively feed biomass into the combustion chamber via the inlet thereof, and a closed configuration for preventing access to and closing off the inlet of the combustion chamber, the door assembly being provided with at least one aeration passage extending between an outer portion of the door assembly and an inner portion therefor, for providing a supply of secondary air to the combustion chamber via said at least one aeration passage of the door assembly when operated in the closed configuration.

Abstract: An actuator for operating a valve comprises a housing, a cap, a ring and a piston. The housing has a connecting interface for being mounted on the valve. The cap substantially covers a first portion of the housing. Both the cap and the housing define a substantially enclosed space inside the housing. The ring sealably covers a second portion of the housing. The ring is equipped with two ports that are in fluid communication with the enclosed space. The piston is slidably located inside the housing. Advantageously, an actuator assembly may include the actuator as previously described and one bonnet, one of the connecting interfaces of the actuator being connected to the bonnet. The bonnet is adapted to be mounted to a valve body.
