    The Model EVH-660D vertical-blade louver has been tested and certified in accordance with Miami-Dade NOA 12-0418.06 and passes the Miami-Dade TAS 100A wind-driven-rain test procedure without the need for a damper. In addition to passing all relative Florida and Miami-Dade impact and structural wind test procedures, Model EVH-660D passes the new AMCA 540 large-missile-impact standard; bears the AMCA seal for water penetration, air performance, and wind-driven rain; and is AMCA-listed as a high-velocity, rain-resistant, and impact-resistant louver. —Greenheck                

    Boiler-reset control

    Hpac Com Sites Hpac com Files Uploads 2013 04 Taco Fuel Mizer

    The FuelMizer is a boiler reset control and switching relay in one unit. The microprocessor-based control is designed to regulate the supply-water temperature of a single boiler based on outdoor temperature. It is well-suited for retrofits, but also can be used for new installations. Functions include automatic reset, ratio calculation, warm weather shutdown, and minimum-boiler temperature and boiler-differential settings. It monitors both a boiler and a system’s outdoor sensors. —Taco     

    Flow sensor

    Hpac Com Sites Hpac com Files Uploads 2013 04 Dwyer Lofm
    The Series LOFM low-flow electromagnetic flow sensor uses the conductivity of fluids to measure flow. Liquid flow through its magnetic field produces a voltage that is measured and translated into a pulse-output signal. The sensor is available for either ¾-in. or 3/8-in. pipe and can accurately measure flow rates as low as 0.03 gpm. A splash-proof HDPE plastic housing makes it suitable for chemical-injection applications. It is corrosion-resistant and has no moving parts, making it compatible with a wide range of chemicals and well-suited to handle dirty-water applications. —Dwyer Instruments                              

    Monitoring system

    Hpac Com Sites Hpac com Files Uploads 2013 04 Virtjoule Cellular Montior
    HVAC Cellular Monitor is a monitoring system for HVAC and refrigeration units that texts a message to a designated cell-phone number if out-of-hours operation, excessive runtime, or imminent failure of a unit is detected. The patent-pending system is designed to optimize energy efficiency for buildings of all sizes and extend the life of HVACR units. —Virtjoule                           

    Custom air handlers

    Hpac Com Sites Hpac com Files Uploads 2013 04 Daikin Mc Quay Custom Air Handler
    The Daikin McQuay custom air-handler line offers virtually unlimited configurations. The length, width, and height of units can be varied in 2-in. increments, so they can fit into critical spaces and through fixed doorways. The units’ low-leakage cabinet construction incorporates a patented splice-collar design and welded frame channels. Options include energy-recovery wheels, direct-drive plenum-fan arrays, and an extensive coil selection.— Daikin McQuay

    Rooftop split system

    Hpac Com Sites Hpac com Files Uploads 2013 04 Reznor Rhh Installed

    The Model RHH high-efficiency rooftop-mounted split system is up to 92-percent fuel-efficient. It is capable of handling up to 100-percent outside air. Like the other split systems in Reznor’s PreevA line, Model RHH offers the flexibility of multiple configurations. Choices include direct-expansion (DX) or chilled-water cooling, and DX cooling with dehumidification. The system allows 17 different configurations for makeup air, space-temperature control, thermostat control, and other user control inputs. —Reznor          

    Fixtureless UV-C system

    Hpac Com Sites Hpac com Files Uploads 2013 04 Uv Resources Rlm Xtreme
    The RLM Xtreme fixtureless ultraviolet-C (UV-C) lamp system delivers high-output ultraviolet energy to irradiate air-conditioning coils and destroy mold, bacteria, and microbes in demanding, high-volume HVAC environments. The system combines name-brand components in a simple, flexible design that is easily configurable to fit into almost any plenum. Scissor-like overlapping of lamps eliminates the need to specify and size multiples of fixtures and lamps. The system can be installed in almost any position to direct 360-degree UV-C irradiation to where it is needed most. —UV Resources
