The Modu-Fire® FD noncondensing boiler is now available in two additional sizes: 2.5 million and 3 million Btuh. With Canadian Standards Association-certified efficiency of 88 percent, the N2500MFD and N3000MFD boilers have the highest efficiency of their class, claims the company.
The Copeland Scroll® outdoor condensing unit is designed for medium- and low-temperature refrigeration applications. With advanced PerformanceAlert™ diagnostics and a fault history feature, it offers diagnostic protection capabilities for the entire system and permits more accurate troubleshooting.
The XFyre modulating, condensing boiler is available in sizes from 300 to 850 MBtu. The boiler achieves 94 percent thermal efficiency at full fire, up to 99 percent part load. A direct spark ignition system combined with zero governor fuel-air matching allows smooth soft start and modulation with 5:1 turndown capability.
The Steam Grid is designed to control indoor humidity levels. The multitube steam dispersion system is installed within the humidification section of an air handler to distribute steam over the entire surface of the air handler section, reducing the absorption distance.
Eco-Dry™ desiccant dehumidifiers optimize performance over a wide range of operating conditions from full to off-peak loads by monitoring humidity and adjusting operating parameters. They have BrySmart control technology, which reduces energy usage up to 45 percent, says the company.
The Viconics BACnet Zoning System (VBZS) is a native BACnet-based changeover bypass-type zone control system. It features pre-programmed zoning system algorithms, automatic binding of time schedules and heating and cooling demands, and an onboard menu-driven setup-configuration tool.
The Envision™ NXW Series of reversible chillers are now available in 8- to 20-ton sizes. These water-to-water heat pumps provide water heating and cooling for a wide range of applications, including pools, commercial aquariums, radiant floor heating, ice melt, and chilled-water.
The refrigeration system analyzer features a digital, full-color thin film transistor display with adjustable brightness and contrast protected by an anti-glare, scratch-resistant lens. The display reads in analog, digital or a combination of both.
A full range of variable air volume (VAV) terminals are available as part of an expanded product line for commercial and light commercial HVAC systems. The VAV terminals can be utilized in large, complex facilities as well as medium-sized and low-rise buildings. Airflows range from 100 to 8,000 cfm.
The Stinger™ refrigerant recovery unit is ideal for the recovery of refrigerants from air conditioning units or refrigeration systems for residential and light commercial equipment, says the company. The unit comes equipped with an automatic vacuum shutoff, allowing for unattended recovery operation.
