Cooling Tower Direct Drive Motors Lead to Energy Efficiency Gains

By Sean Mullins, Product Manager – Laminated Frame Motors, ABB

Across industries, operators are adopting cooling tower direct drive (CTDD) motor technology. In particular, permanent magnet (PM) direct drive motors are delivering measurable improvements in efficiency, cleanliness and maintenance reduction. The change is more than a component swap; it represents a new approach to cooling tower design that reduces operating costs, supports environmental goals and improves reliability.

Adiabatic Cooling, the New Happy Medium

By Mihir Kalyani, Data Center Business Unit Manager, Americas, EVAPCO

The need for cooling capacity is increasing globally. An expanding population and an ever-growing dependence on data increases the need for process cooling, centralized space cooling, and data center cooling. Meanwhile, in many places, water scarcity is a massive issue. In conventional, industrial cooling applications, the use of water for heat rejection is critical. Cooling towers and most evaporative fluid coolers depend heavily on water to reject waste heat to the atmosphere.
