A wall mount kit allows the drive to be mounted separate from the motor if needed.
Mitsubishi Electric US, Inc. has developed the new CITY MULTI® L-Generation water source condensing systems. Combining the efficiency of water source with VRF, the company claims the next-generation W-Series systems offer enhanced efficiency ratings across all categories. The systems feature single modules up to 20 tons, with the ability to combine single modules for systems up to 30 tons. W-Series systems can also be integrated into specialized water-side designs, such as geothermal or existing closed water loops.
Titus has introduced the new FlowBar architectural linear diffuser system. Officials claim the diffuser has been designed to maximize engineering performance without sacrificing aesthetic considerations for the designer. The company also says FlowBar’s performance allows higher airflows than conventional linear diffusers.
DuctSox has introduced the SkeleCore™ FTS Jumbo Series that offers 50- to 84-in diameters. The Jumbo Series is an ideal fabric duct solution for large airflow distribution requirements in high-ceiling or high bay spaces such as athletic stadiums, convention halls, aircraft hangers, industrial buildings, and other applications.
The Remote Lamp Mount (RLM) Small Systems (S/S) ultraviolet (UV-C) lamp fixture kit from UV Resources is designed to deliver ultraviolet energy to destroy coil/drain pan microbial infestations and disinfect moving air streams in hard-to-service fan coil units, PTAC units, and heat pump systems.
