The Dow Chemical Co. LIQUIDARMOUR-CMCommercial use flashing, sealant

LIQUIDARMOR-CM liquid flashing and sealant provide commercial buildings with advanced moisture and air sealing protection. An innovative alternative to flashing tape, the elastomeric spray forms a tight, seamless barrier along the rough openings of windows and doors while helping to significantly reduce labor time. The product offers an alternative sealant solution to conventional flashing and sealing products for installation of THERMAX or the Ultra Air Barrier 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 flashing tapes commonly used on board joints of commercial buildings.

DunAn Microstaq silQflo Silicon Servo ValveCooling, expansion microvalve

The silQflo 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 efficiency ratings. Due to silQflo Silicon Servo Valve's ultra-fast response feature, it can achieve precise superheat control by quickly adjusting to varying load conditions.

Energence ultra-high-efficiency rooftop unitsUltra-high-efficiency rooftop units

Energence ultra-high-efficiency rooftop units feature efficiencies 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-efficiency lineup exceeds ASHRAE 90.1 minimum standards by 92%, exceeds CEE Tier 1 and 2 efficiency minimum requirements, and qualifies for many potential utility rebates and incentives, while also providing additional options to meet California Title 24.


Laars Heating Systems MagaThermModulating, condensing boiler

MagnaTherm is a 95% thermal efficiency 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 certified. The boiler features an advanced VARI-PRIME pump control that seamlessly matches boiler firing rate to pump flow, reducing boiler pumping costs by up to 70%.

Titus HVAC Atlas Operating Room Ceiling SystemIntegrated ceiling system

The Atlas Operating Room Ceiling System (AORCS) custom-engineered, integrated ceiling system for operating rooms allows facilities to simplify design and installation while easily adapting to future ceiling layouts. Components include air curtain diffusers that isolate contaminants from sterile areas. These diffusers are integrated with LEDs, providing light directly over operating tables rather than farther out like standard grids and systems. AORCS can be used with any diffusers and lights, giving facilities full control over what pieces they'd like to implement in the system. AORCS is equipped with a unique antimicrobial finish and gasket that prevents and stops bacteria growth.
