At Pfannenberg, they have developed simple rule-of-thumb guides for selecting and sizing variable frequency drives cooling solutions.
 

Location isn’t everything, but it helps. Just ask homeowners selling their property, or restaurant owners. In the HVAC world, it also rings true for some motors and drives and the professionals who work with them. That includes contractors, even if maybe not in the way that one would expect. Some current and next-gen drives will make location matter in a new way: Contractors can spend more time further away from the equipment itself.

It’s the first R&D 100 award for Franklin Control Systems, and second for Franklin Electric. 

All Optidrive P2s provide 150 percent overload for 60 seconds as standard, ensuring each drive is suitable for heavy-duty applications.

The app replaces the need to access controls directly on the drive while providing an easy-to-understand display.

Intended for large industrial and commercial applications, the Climate 6000 AH Series comes in 21 different sizes. Horizontal unit configurations range from 800-38,000 cfm while vertical configurations are available in 800-4,000 cfm.

Invertek, which manufactures its variable frequency drives at its headquarters in Welshpool, exports them worldwide for use in applications including general automation, pump control, HVAC building services, elevators, and marine equipment.
