A belt tensioning system for a motor and a belt-driven blower each secured inside an air handling unit. The blower rotatably carries a first shaft, a first sheave and a bladed arrangement being secured to the first shaft. A second sheave secured to a second shaft is rotatably carried by the motor. A belt engaging the periphery of the first sheave and the second sheave urges the first sheave to rotate about the first shaft in response to the motor urging the second sheave to rotate about the second shaft. An adjuster having adjustment means is secured to the structure. Actuating the adjustment means in a direction urges the motor either toward the adjuster or away from the adjuster to vary the distance between the first sheave and the second sheave to vary the tension in the belt.

Motor belt tensioning construction for an air handling unit

An air handling unit (AHU) for housing a number of components used in a heating or cooling system to provide forced air for climate control in a particular structure includes a single raceway construction having both low thermal conductivity and enhanced mechanical properties for use with lifting the AHU; a single insulated panel construction having a minimum number of components as well as enhanced mechanical properties for use as the floor in an AHU compartment; to minimize costs associated with fabrication and installation.

Raceway construction for an air handing unit

A support system for an air handling unit (AHU) including a first rail supporting the AHU and a second rail supporting the first rail. A vibration isolator is disposed between the first rail and the second rail to vibrationally isolate the AHU from the second rail. The vibration isolator includes a spring secured between opposed spring retainers. An adjusting member threadedly receives the upper spring retainer. The first rail structurally carries the guide member along at least two positions. An angle is secured to the second rail, and the second end of the structural member slidably engages the guide member. Rotating the adjusting member with respect to the spring retainer in one direction compresses the spring between the spring retainers to support the weight of the first rail and the AHU. The angle constrains the AHU to movement along the guide member.
