Abstract: A system and method reduce a concentration of viable microorganisms, including but not limited to the 2019 novel (new) coronavirus that causes the illness coronavirus disease 2019 (COVID-19), in air in a workspace by over 80% with a single pass of air through the system. A heater heats air drawn from the workspace and a desiccant dehumidifier further heats air from the heater. The heater and desiccant dehumidifier decontaminate the air to kill or inactivate the microorganisms so that air returned to the workspace from the system has a reduced concentration of viable microorganisms.

Abstract: Dessicants employed in dehumidifying moisturized air present within a water-damaged building are themselves dehumidified to liberate collected moisture through the use of heated air vented from an on-site electric generator to be drawn over and about a heat exchanger fired by diesel fuel.

Abstract: Ice-clad machinery and equipment in very cold environments are made more easily recoverable by enclosing the machinery and equipment in an environmentally contained area and introducing desiccant dehumidified air into the contained area to lower the vapor pressure in fostering a “sublimation” process conversion from the solid state of the ice to a gaseous state which can be exhausted without first going through any intermediate liquid state.

Abstract: Dessicants employed in dehumidifying moisturized air present within a water-damaged building are themselves dehumidified to liberate collected moisture through the use of ambient air drawn over and about a heat exchanger fired by diesel fuel, with portions of the air drawn through the dessicant in both directional air flow paths being used to heat the water-damaged building.

Abstract: Dessicants employed in dehumidifying moisturized air present within a water-damaged building are themselves dehumidified to liberate collected moisture through the use of ambient air drawn over and about a heat exchanger fired by diesel fuel, with a portion of the dehumidified air being diverted to join with the ambient air in increasing the liberation of the moisture within the dessicant.

Abstract: Rotating wheel dessicants employed in dehumidifying moisturized air present within a water-damaged building are themselves dehumidified to liberate collected moisture through the use of ambient air drawn over and about a heat exchanger fired by diesel fuel, with the rotating wheel dessicant being turned by a grip notch belt stretched onto the wheel.

Abstract: Dessicants employed in dehumidifying moisturized air present within a water-damaged building are themselves dehumidified to liberate collected moisture through the use of ambient air drawn over and about a heat exchanger fired by diesel fuel and powered by a pair of separately fused electrical circuits, one of which powers a first blower drawing ambient air from outside the building over the heat exchanger and through a dessicant in a first direction, and the other of which powers a second blower drawing moisturized air from within the building through the dessicant in a second direction.

Abstract: Dessicants employed in dehumidifying moisturized air present within a water-damaged building are themselves dehumidified to liberate collected moisture through the use of ambient air drawn over and about a heat exchanger fired by diesel fuel, with the dessicants, the dehumidifying apparatus and the diesel fuel all being carried on a trailer, with the diesel fuel inside under a skid and with its own portable electric panels with ground fault interrupters aboard in bringing its own electric power to the scene of the water-damaged building.

Abstract: A raised ring encircling a duct at an output port of a desiccant dehumidifier housing prevents its flexible hose from blowing off the duct even when clamped, as dried air blowing pressures through the duct increase.
