The best in HVAC is now better than ever


As the world’s population continues to increase, energy-optimized HVAC systems are the key to providing comfort and safety without increasing energy consumption. Even extreme climates and isolated outposts have a need for efficient HVAC operation. To give you the flexibility you need with the reliability you expect, the VLT® HVAC Drive has been enhanced to meet your needs – and more.

It’s more efficient…

New motor technology is driving an increase in operating efficiency, especially in HVAC applications. In order to get the most out of these PM and SynRM motors, an AC drive with the algorithms to most optimally control these motors is necessary. A single VLT® HVAC Drive can not only optimally run these motors, but can now control multiple IE5 PM motors in parallel for even greater efficiency.

It’s smarter…

HVAC applications can be found everywhere, including in isolated area and in hard-to-reach locations. This requires new ways of thinking in order to efficiently communicate with these drives. Our updated Web Server integrated in the Ethernet options and new Wireless LCP provide even more ways to remotely and securely connect to your VLT® HVAC Drive.

It’s tougher…

These days, HVAC applications are often challenged by temperature fluctuations, seismic activity, areas with high levels of atmospheric pollutants, unstable grid quality or a mixture of these conditions. The VLT® HVAC Drive is designed to meet these challenges head on.

With a wide operating temperature range from -25°C up to 50°C and an availability of enclosure classes up to IP66/UL Type 4X, the VLT® HVAC Drive can be installed almost anywhere without derating. The addition of seismic certification, the ability to install to altitudes of 2000 m/6500 ft without derating, and options for conformal, harsh environment coating to 3C3, further improve the VLT® HVAC Drive’s ability to work reliably in the most demanding environments.

It’s more reliable…

With billions of people all around the world relying on HVAC systems for comfort and safety, it’s vital to select an AC drive that can withstand unforeseen grid fluctuations that would otherwise interrupt operations. To improve ride through, the VLT HVAC® Drive’s robust overvoltage controller, kinetic backup and improved flying start ensure reliable operation when it’s needed most.

AC drives often require connections to grids that are far from perfect, and a host of electrical events can cause serious issues with drives. Algorithms in the VLT® HVAC Drive ensure that, even when there are spikes and dips in voltage, the drive will continue to operate as expected. Occasionally, an AC drive may be connected to a system that experiences a short-circuit which could potentially destroy the connected drive. To ensure reliable operation, the VLT® HVAC Drive is designed to be short-circuit proof with a 100 kA prospective short circuit current capability.

It’s a small investment with a big return…

New energy efficiency regulations focus on ways to reduce energy consumption and CO2 emissions. To meet these new standards, adding an AC drive is a necessity. Over the lifetime of an AC drive, energy cost is the dominating economical factor, but savings can be found in other associated costs.

Selecting the VLT® HVAC Drive provides the lowest total cost of ownership. Installation and commissioning take 20% less time and it has 2% improved operating efficiency than comparable drives. And, based on average operating time, the VLT® HVAC Drive will operate maintenance-free for up to 15 years.

With a range of new features that make the drive tougher and smarter to ensure reliable operation in the harshest conditions, improved process efficiency and enhanced accessibility – what’s not to like?! Watch this video to learn more:

  1. When this part of LCP 103 can be order?

    • Hi Natan,
      We’re aiming for the release of the LCP 103 in early Q4.
