Abstract: An exhaust hood may have an exhaust inlet; a shroud having a lower edge and being movable, the shroud being configured to define an enclosed space over and adjacent a cooking surface, the enclosed space being in communication with the exhaust inlet. The shroud is movable to a first position providing clearance between the cooking surface and the shroud lower edge and a second position providing substantially less than the clearance provided by the first position. A vertical jet at the lower edge is aimed upwardly and along an inside of the shroud when the shroud is in the second position and the vertical jet is in the enclosed space. A horizontal jet is provided at a top of the shroud and aimed along an inside of the shroud when the shroud is in the second position and the vertical jet being in the enclosed space.

Abstract: A services supply device for a commercial kitchen includes multiple wall modules that are interconnectable to form a continuous wall. The continuous wall is defined by a pair of common substantially planar surfaces, one at the front side of the wall and one at the back side of the wall, spaced apart by some distance. The interior of the wall between the front and back sides forms a cavity. A portion of the cavity may be configured as an exhaust duct that conveys exhaust fumes away from a cooking appliance serviced by the services supply device, while another portion may be configured as a filter. The exhaust duct may have an inlet positioned on one of the sides of the continuous wall. The individual wall modules may be formed from functional units stacked on top of each other.

Abstract: A flow control device has a duct section with a plurality of damper blocking elements, each having a major plane. The damper blocking elements are pivotably connected to the duct section and movable in a range that is limited to ensure that, when the duct section is mounted in a preferred orientation, the damper blocking element major planes always form an angle of at least 45 degrees from the horizontal throughout the range. The range is such that the plurality of damper blocking elements can selectively close and open the duct. The blocking elements can completely close the duct, for example, to block natural convection.

Abstract: Systems, devices and methods provide energy recover, modular systems to build and revise commercial kitchen services, closed circuit exhaust, and high efficiency capture and containment of fumes from cooking processes.
