The ABD can be installed directly into round duct work without the need for any fasteners or use of any adhesive.
Regulates temperature and provides ventilation for equipment in demanding applications Greenheck’s AER direct drive configurable condenser fan can help regulate temperature and provide proper ventilation for your equipment, even in the most demanding applications where elevated water and temperature protection is required. Available in four sizes ranging from 20 to 36, the AER condenser fan offers performance up to 29,800 cfm and external static pressure up to 2.80 in. wg.
Greenheck’s line of SQ direct drive mixed flow inline fans offering a unique combination of high efficiency, low sound, and ease of installation in a square housing design continues to expand and add enhancements. With the addition of sizes SQ-7 and SQ-9 covering lower CFM selections from 100 to 2,300 cfm, the SQ mixed flow line is now available in twelve sizes, 7-33, with performance ranges up to 27,800 cfm and up to 3 in. wg. A new side discharge option helps to reduce system effect, improves system performance, and reduces installation labor as fans are configurable with a variety of discharge options—inline, left, right, or any combination of the three.
GREENHECK LAUNCHES AIR DISTRIBUTION PRODUCT LINE New Product Line Allows for Single-Source HVAC System Specification Greenheck recently added air distribution products to its industry-leading product line making it even easier to specify a complete ventilation system from one supplier. Greenheck’s air distribution products include an extensive selection of grilles, registers, diffusers (GRDs), and air terminal units (ATUs) that are designed, engineered, and tested to meet a wide range of performance and aesthetic requirements. Greenheck offers hundreds of air distribution product models including supply and exhaust grilles and registers, ceiling diffusers, linear diffusers and grilles, plenum slot diffusers, and VAV diffusers.
The ABD-Z2 is the latest addition to Greenheck’s line of automatic balancing dampers that provide precise airflow regulation for energy efficient indoor air quality. The ABD-Z2 is an integrated automatic balancing damper (ABD) with an adjustable set point controlled by an electric actuator (24V or 120V). The unit can toggle between two pressure independent CFM set points; the low-flow setpoint maintains a constant minimum ventilation rate, while the high-flow set point provides boosted on-demand ventilation.
GREENHECK MULTISPEC EXHAUST FANS DELIVER INDUSTRY-LEADING PERFORMANCE Greenheck’s new MultiSPEC SP-LP ceiling exhaust fans provide high efficiency, powerful performance, and quiet operation in a low profile design. Powered by an electronically commutated motor (ECM) with constant CFM adaptive, variable speed technology, the MultiSPEC SP-LP is programmed to overcome static pressures of 0.4 in. wg and above associated with common multifamily installations.
GREENHECK’S eCAPS BRIDGE TO REVIT STREAMLINES PRODUCT SELECTION Software Plug-In Saves Time in Creating Schedules Greenheck’s eCAPS Bridge to Revit plug-in provides access to the most complete catalog of HVAC product content in Greenheck’s eCAPS online product selection program and makes it easy to select and schedule HVAC equipment without leaving the Revit environment. The plug-in enables specifiers to make model or performance-based selections and seamlessly insert Level of Development (LOD) 200 and 300 content directly into Revit projects. The eCAPS Bridge to Revit plug-in also saves users time by automating the schedule creation process.
Greenheck’s new high-performance residential energy recovery ventilators (ERVs) provide balanced ventilation that improves energy efficiency and ensures multifamily projects meet code and exceed indoor air quality expectations. Four models are available with a variety of options and accessories and all offer Home Ventilating Institute (HVI) certified airflow.Both the ASSURE120 and SYNC110 offer a 50-130 cfm operational range in a compact low-profile design that simplifies installations with limited mechanical space such as bulkheads and drop ceilings. In addition, the SYNC110 is powered by two Electronically Commutated Motors (ECM) with adaptive, variable speed technology programmed to adapt to the static pressure associated with a dirty filter or core.
Greenheck Announces Model RVC Rooftop Unit with Enthalpy CoreNew Model RVC Provides Low Maintenance Energy Recovery Greenheck’s new model RVC (Rooftop Ventilator with Energy Recovery Core) is the latest addition to its dedicated outdoor air systems line for high percentage and 100% outside air applications. Model RVC incorporates a total enthalpy core that provides both sensible and latent heat transfer and meets ASHRAE 90.1 minimum efficiencies. The enthalpy core’s cross-flow design prevents supply and exhaust airstreams from intersecting resulting in an Exhaust Air Transfer Ratio (EATR) of 0 to 1% per AHRI 1060 testing. Model RVC is available in three housing sizes with airflow up to 15,000 cfm and 5 to 70 tons of packaged DX cooling capacity.
Greenheck’s SQ mixed flow fan line featuring a unique combination of high efficiency, low sound, and ease of installation in a square housing design now includes a new outdoor option along with additional accessories and sizes. The SQ mixed flow fan can now be specified for ducted horizontal-mount outdoor applications when space constraints require a cost-effective rooftop-mounted unit. The outdoor option is base-mounted and includes a full cover over the unit to protect electrical components and prevent water entrainment.New accessories include inlet and outlet guards to protect against intrusions; these guards remove easily for maintenance and inspection.
GREENHECK ADDS TWO NEW INDUSTRIAL CONTROL DAMPER MODELSDesigned to Control Airflow in Lab Exhaust SystemsGreenheck has expanded its line of industrial control dampers with two new models specifically designed for lab exhaust systems. Models HCD-130LE and HCD-230LE are heavy-duty flanged-style frame industrial control dampers with fabricated airfoil blades designed to control airflow and provide shutoff in lab exhaust systems. The HCD-130LE has pressure velocity capabilities up to 8.5 in.
