Danfoss has received the Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI) certification for variable frequency drives, confirming the performance of its VLT® HVAC Drives based on rating standards.

According to AHRI, certification under Standard 1210/1211 enables equipment users to make informed, reliable decisions about variable frequency drives. To receive certification, VFDs are rigorously tested according to three standard rating conditions, including efficiency at various speeds and loads, drive-generated harmonics at full load and speed, and peak voltage and rise time.

“We are pleased to offer our customers the assurance of independent AHRI certification, which sets a high bar for reliability and accuracy in the industry,” said James Kluck, senior product marketing manager, Danfoss. “As the first to engineer a variable frequency drive dedicated for HVAC applications, Danfoss is committed to helping equipment manufacturers and building owners enjoy the benefits of better, more reliable control and energy efficiency through VFDs — reducing costs, meeting energy standards, and even enabling utility rebates to be secured. Not only are Danfoss drives designed to be the most intelligent, easy-to-use solution on the market, but, now, industry-recognized AHRI certification verifies that they truly are the reliable, high-performance solutions our customers have depended on for more than 30 years.”

Engineered specifically for the unique needs of HVAC pump, fan, and compressor applications, Danfoss VLT® HVAC Drives enable optimized process control to reduce energy consumption, meet environmental targets, and significantly reduce costs in today’s buildings.

Featuring an easy-to-use design with built-in intelligence, the AHRI Certified® drives are fast and cost-effective to commission, and ensure maximum uptime even in harsh environments. A compact design and efficient heat management system make VLT® HVAC Drives ideal for applications where space is restricted. With the intelligence built into the drive to precisely maintain the exact flow required using the four auto-tuning, multi-input, multi-control PID’s, users experience the control and comfort expected.

Available enclosures include NEMA/UL Type 1,12, 3R and 4X, with coated circuit boards providing an extra layer of protection. Integrated DC chokes and RFI filters safeguard installations by minimizing harmonic distortion and electromagnetic interference. Having the right mix of hardware features, software features and the ability to communicate with building automation systems makes the VLT® HVAC Drive an ideal solution for precise, efficient, reliable HVAC.
