2015 HVAC Commercial use flashing, sealant LIQUIDARMOR-CM liquid fl ashing and sealant provide commercial buildings with advanced moisture and air sealing protection. An innovative alternative to fl ashing tape, the elastomeric spray forms a tight, seamless barrier along the rough openings of windows and doors while helping to signifi cantly reduce labor time. The product offers an alternative sealant solution to conventional fl ashing and sealing products for installation of THERMAX or the Ultra Air Bar-rier Wall Systems. LIQUIDARMOR-CM covers and seals hard-to-reach gaps up to ¼ in. wide and offers a reliable replacement to peel-and-stick fl ashing tapes commonly used on board joints of commercial buildings. The Dow Chemical Co. Cooling, expansion microvalve The silQfl o Silicon Servo Valve functions as an ultra-fast electronic expansion device with cooling capacity up to 500 W. The compact size and lightweight design makes it ideal for any application, particularly those with space constraints. The microvalve can be packaged into any form factor per application requirements because of its small footprint. The low-capacity applications are in need of an electronic expansion valve because of the constant demands in higher energy effi ciency ratings. Due to silQfl o Silicon Servo Valve’s ultra-fast response feature, it can achieve precise superheat control by quickly adjusting to varying load conditions. DunAn Microstaq Inc., Ultra-high-efficiency rooftop units Energence ultra-high-effi ciency rooftop units feature effi ciencies of up to 21.5 IEER and 13.9 EER, resulting in overall low operating costs and service. The units are designed to help buildings qualify for LEED points, as well as local utility rebates. Other features include the Advanced Cooling System and the DirectPlus blower system. In addition to sustained savings, the Energence ultra-high-effi ciency lineup exceeds ASHRAE 90.1 mini-mum standards by 92%, exceeds CEE Tier 1 and 2 effi ciency minimum requirements, and qualifi es for many potential utility rebates and incentives, while also providing ad-ditional options to meet California Title 24. Energence Modulating, condensing boiler MagnaTherm is a 95% thermal effi ciency modulating-condensing boiler or volume water heater available in 1.6, 2, 2½, 3, 3½, and 4 million Btuh sizes. MagnaTherm offers a 5:1 turndown, small footprint, slim vertical design with removable top section, a stainless steel heat exchanger, and multiple voltage options to easily match building service. Designed and made in the U.S. by Laars, the MagnaTherm meets all ASME requirements and is AHRI certifi ed. The boiler features an advanced VARI-PRIME pump control that seamlessly matches boiler fi ring rate to pump fl ow, reducing boiler pumping costs by up to 70%.
