The latest additions to the ARMOR family of water heaters are wall-mount models with inputs of 125,000 Btuh and 199,999 Btuh. The units offer up to 96 percent thermal efficiency with a 5:1 turndown and a compact design that fits tight installations. They are designed to be installed with a separate unfired storage tank, which prevents lime-scale buildup from impairing a system’s heat-transfer efficiency. —Lochinvar In-line expansion joint
Wet-rotor Viridian pumps feature electronically commutated motors, fully automated self-sensing variable-speed operation, and simple Web-style controls. They are available in capacities of up to 375 gpm. An Ethernet connection allows remote control, monitoring, and adjustment. The Viridian is suitable for fluid temperatures from 14°F to 230°F and water/glycol mixtures in concentrations of up to 50 percent. —TacoRedesigned UV-C fixture
Designed for commercial hydronic applications, the MAGNA3 variable-speed wet-rotor circulator features the AUTOAdapt function, which automatically and continuously adjusts circulator performance, and the FLOWADAPT control mode, which reduces the need for pump throttling valves. The pump’s variable-speed, electronically commutated motor uses an integrated logic algorithm to “learn” the energy-usage patterns of an application over time, enabling the software to automatically determine the lowest operating‐ efficiency point to meet ever-changing demand. —GrundfosLiquid-desiccant system
The Titus augmented-reality (AR) app allows smartphones and tablets to recognize images in Titus HVAC literature and printed documents and augment it with hidden content, such as video, animation, and drawings. The free app is designed to provide consulting engineers with additional explanations and make content easier to understand by seeing it in action using multimedia channels. The company has incorporated Titus AR logos in print catalogs, equipment, advertisements, and business cards. Customers simply download the Titus AR app and then use their smartphones to scan the logo to unlock the hidden content. —TitusBuilding-automation gateway
Variable-refrigerant-flow with heat recovery
Carrier has expanded its variable-refrigerant-flow (VRF) offerings to include heat-recovery models under the name Toshiba Carrier SHRM-i. Toshiba Carrier SHRM-i VRF systems feature multiple inverter-driven compressors. The three-pipe heat-recovery systems are well-suited for applications requiring simultaneous heating and cooling, maximizing efficiency by transferring energy from one indoor zone to another through refrigerant piping. —Carrier
AppStat BAC-4000 thermostats combine a BACnet controller and temperature/humidity/motion-sensor options in a single, space-mounted device. AppStat is an integrated native BACnet application-specific controller. No external communication or occupancy modules are required. All models include an integrated BACnet schedule and hardware real-time clock with 72-hr capacitor backup for stand-alone operation or network time synchronization. —KMC ControlsWater-source heat pump
