USA – Mestex introduced its latest HVAC product design, the Aztec AMC during the AFCOM 2015 Data Center World event last week at the Mirage Resort and Casino, Las Vegas. The Aztec AMC was designed to conform to the more stringent codes and standards required for commercial HVAC systems, such as data center applications.
The new product features energy-efficient evaporative cooling technology and an advanced air turnover system, which is an unusual combination in industrial applications.
Rose Samano, sales manager for Mestex, introduced the product, saying “A flexible, scalable and energy-saving method for data center capacity planning and cooling — known as ‘build as you grow’ — is gaining momentum. Adding plug-and-play units, such as the Aztec AMC, as capacity increases is an economical strategy.”
Mestex claim that the Aztec systems, which have the ability to harness cooler outside air to support indoor cooling, reduce power consumption by up to 70% in comparison with traditional air conditioning (including computer room air conditioning [CRAC] units.) The company also states that the system’s digital controls, when integrated with other building automation systems, may help to further increase those energy savings.
“Unlike other technologies just starting to be developed to reduce energy, costs and environmental impact, this technology is available today — and proven effective,” added the president of Mestex, Mike Kaler. “For the foreseeable future, HVAC purchasing decisions will be based on the ability to reduce energy consumption and costs.”
The new Aztec AMC HVAC system is expected to deliver high-performance air handling efficiencies through the use of direct-drive plenum fans with Variable Frequency Drive (VFD) controls which help reduce energy consumption when the equipment is operating at part load. The system also features refrigerant-free evaporative cooling technology, which reduces power usage by around 70% when compared to traditional air conditioning, and direct digital controls which can be used to help monitor and adjust HVAC systems for comfort, costs and energy efficiency. These controls can be accessed remotely at any time by a web interface or locally using a new equipment-mounted or wall-mounted touch screen.
