A system for venting a solvent, the system comprising: an oven having an interior volume defining a heating zone , the interior volume for receiving at least one substrate coated with a coating material comprising a solvent; a vent coupled to the oven , the vent defining a passage between the interior volume and an environment external to the oven and having a regulator that can be adjusted to vary a rate at which evaporated solvent can flow from the interior volume of the oven to the environment external to the oven , wherein the regulator is positioned adjacent the interior volume of the oven , inside the passage defined by the vent , a solvent sensor at least partially located in the interior volume and configured to measure an amount of the evaporated solvent present in the interior volume ; a fan in fluid communication with the passage and configured to remove at least a portion of the evaporated solvent from the interior volume , characterised in that a speed of the fan is controlled based on the measured amount of the evaporated solvent present in the interior volume , wherein, if an evaporated solvent concentration equals or exceeds a first threshold, the system toggles the regulator from a closed configuration to a semi-open configuration to open the passage of the vent , wherein, if the evaporated solvent concentration then reaches a second threshold that is higher than the first threshold, the system actuates the fan to actively move the evaporated solvent through the vent by turning on the fan or increasing the speed of the fan , and wherein, if the evaporated solvent concentration continues to a third, shutdown threshold that is higher than the second threshold, the system is configured to shut down. an oven having an interior volume defining a heating zone , the interior volume for receiving at least one substrate coated with a coating material comprising a solvent; a vent coupled to the oven , the vent defining a passage between the interior volume and an environment external to the oven and having a regulator that can be adjusted to vary a rate at which evaporated solvent can flow from the interior volume of the oven to the environment external to the oven , wherein the regulator is positioned adjacent the interior volume of the oven , inside the passage defined by the vent , a solvent sensor at least partially located in the interior volume and configured to measure an amount of the evaporated solvent present in the interior volume ; a fan in fluid communication with the passage and configured to remove at least a portion of the evaporated solvent from the interior volume , characterised in that a speed of the fan is controlled based on the measured amount of the evaporated solvent present in the interior volume , wherein, if an evaporated solvent concentration equals or exceeds a first threshold, the system toggles the regulator from a closed configuration to a semi-open configuration to open the passage of the vent , wherein, if the evaporated solvent concentration then reaches a second threshold that is higher than the first threshold, the system actuates the fan to actively move the evaporated solvent through the vent by turning on the fan or increasing the speed of the fan , and wherein, if the evaporated solvent concentration continues to a third, shutdown threshold that is higher than the second threshold, the system is configured to shut down. <EOS>
