Abstract: A method for drying includes positioning an exchanger snout of a portable heat exchanger assembly under an edge of a carpet or flexible barrier, removably coupling a snout of a portable centrifugal air mover with an inlet port of the portable heat exchanger assembly, and activating the centrifugal air mover so that air blown from the snout of the air mover passes through the heat exchanger assembly and exits out through the exchanger snout under the edge of the carpet or flexible barrier, the air being heated as it passes through the heat exchanger assembly.

Abstract: A heat exchanger assembly includes a housing at least partially bounding a chamber and a heat exchanger at least partially disposed within the chamber, the heat exchanger containing tubing adapted to allow a heated fluid to travel therethrough and fins outwardly projecting from the tubing, the fins being spaced apart such that air can freely flow between the fins. The heat exchanger also includes an inlet port into which an air mover can be received to provide blown air for the system and an outlet port through which the heated air exits the heat exchanger assembly.

Abstract: An injection spraying system includes a container having a compartment configured to hold a first fluid. A valve body is removably coupled with the container and includes a mixing chamber, an inlet passageway configured to deliver a second fluid to the mixing chamber, a discharge passageway extending from the mixing chamber, a stem compartment communicating with the mixing chamber through a control orifice, and a transition passageway in fluid communication with the stem compartment. Movably disposed within the stem compartment is a metering stem having a tapered nose configured to selectively engage the control orifice. An adjustment knob is mounted to the metering stem such that rotation of the adjustment knob selectively advances and retracts the metering stem within the chamber of the meter tube. A siphoning tube has one end disposed within the compartment of the container and an opposing end in fluid communication with the transition passageway.
