The present disclosure relates to a heating system comprising: a heating element for heating a process medium; a DC power converter configured to receive an input direct-current voltage from a power supply and to deliver an output direct-current voltage to the heating element; a sensor arrangement configured to generate a first sensor output signal indicative of a thermodynamic parameter of the process medium or the heating element; and a controller configured to control the DC power converter based on the first sensor output signal.

Heating system and method of heating a process fluid

Enclosure comprises a plurality of bar members translatably attached to an interior surface of the door of the enclosure. Each of the plurality of bar members comprises a projection. A plurality of blocks are disposed on a peripheral edge of the opening of the enclosure's body, such that there is a corresponding block for each projection, and wherein each of the plurality of blocks define a channel for receiving and engaging its corresponding projection. When actuated in a first member, an actuator causes each of the plurality of bar members to translate between a first position and a second position. When the door is in a closed position, translation of the bar members to the first position causes each projection to engage with the channel of its corresponding block to thereby hold the door in the closed position. Translation of the plurality of bar members to the second position causes each projection to be translated out of engagement with its corresponding block such that the door can be opened.
