Integrating power and control
Article Abstract:
Intelligent control is required in motor protection to guarantee both energy efficiency and the integrity of electrical systems. Newer control and protection systems utilize power bus to energize all electrical components. Control bus is linked to a programmable logic controller (PLC) or computer to supply several functions to a facility, including control, protection, diagnostics and communications. Control bus is often used to control varied functions such as process, heating, ventilation and air-conditioning (HVAC), lighting, energy management, predictive maintenance, security and other building subsystems.

Saddled with an unusual solution
Article Abstract:
A saddlebag mechanical equipment room provided the engineering solution to the challenges posed by combining specialized heating, ventilation and air-conditioning design in a high-rise building. The 4-story mechanical saddlebag is split into a pair of two-story mechanical rooms that serve two floors each. Inside each room, two supply air-handling systems provide conditioned air to each floor. This solution offered a number of key advantages such as the easy access of supply system mechanical equipment in one area.

Desiccant dehumidifiers save the day for plastics manufacturing plant
Article Abstract:
Process Cooling Systems Inc of Atlanta, GA, specified two desiccant dehumidifiers outside the injection molding plant of Constar International to control humidity and avoid condensation on the molds. The dehumidifiers complement the plant's current air-handling system by taking away internal moisture and bringing dry air in the facility's distribution air. The system also has the capacity to collect from 10% to over 10,000% of the dry weight in water vapor.
