Danfoss VLT Drives: HVAC DrivesThe NEMA/UL Type 4X VLT® HVAC drives deliver reliable operation in environments subject to windblown dust, and rain or splashing water, so they can be installed directly at the equipment location. All cast aluminum parts are powder-coated with a durable epoxy that can withstand most corrosive chemicals. Because the drives are inherently UL Type 4X, there is no need for a separate enclosure. According to the manufacturer, being able to install drives at the equipment location promotes a modular design that maximizes flexibility and allows easy adaptation as operation needs evolve. This also minimizes cable runs which can improve reliability and significantly reduce electromagnetic interference (EMI) or radio frequency interference (RFI) issues. The unit features a watertight USB connection allowing for setup and programming with the drive enclosure sealed. The drives are available in a 1.5-60 hp: 200- 240 V; 1.5-125 hp: 480 V; and 1.5-125 hp: 600-V power range. They are a perfect solution for demanding HVAC applications such as air handlers, pump stations, cooling towers, and other outdoor applications, the company said.
