Consulting-Specifying Engineer 2017 Product of the Year Finalists
Read about the 14 finalists in the HVAC category for the Consulting-Specifying Engineer 2017 Product of the Year program.
ECM fan array
The software-selectable, factory-installed electronically commutated motor (ECM) fan array integrated with semi-custom air handlers accommodates up to 20 ECM fans in 40 arrangements to meet application requirements. The solution delivers space-saving cabinet design, greater efficiencies, quieter operation, and reduced maintenance; mission critical applications benefit from n+1 redundancy. Each fan’s ECM mounts directly to its impeller for compact design, eliminating nearly 3 ft of cabinet space, which makes the unit 46% narrower than direct-drive cabinets with VFDs. Air-handlers with the ECM fan array can gain 40% efficiency (3- to 5-hp range) over direct-drive or belt-driven fans, yielding significant yearly energy savings.
Anti-microbial cooling tower
The Anti-Microbial Cooling Tower boasts additional protection against Legionella risk. The anti-microbial compounded resin is a blue color to make these cooling towers distinctive in the field as a tower with this protection. Extra protection is provided by the sloped basin designs in larger towers that prevent stagnant water areas. The anti-microbial concentrate is compounded into the cooling tower base resin permanently before molding the casing as well as the PVC fill material, which also has anti-microbial compounded into raw material before forming. It is applicable for all cooling tower applications: HVAC comfort cooling, industrial process, and power generation.

Designed and built for HVAC systems where moderate-capacity humidification requirements are common, the Ultra-sorb MP is a framed steam-dispersion panel for pressurized and atmospheric steam applications in air handling units or ducts. The Ultra-sorb MP features dispersion tubes specially engineered to provide maximum air contact at design capacity. These tubes are designed for rapid, drip-free absorption so steam does not condense on downstream devices. The high-efficiency insulated dispersion tubes are available as an option, providing up to an 85% reduction in wasted energy by significantly reducing airstream heat gain and condensate production.
DataSox distributes a large volume of air down into data center cold aisles, but with low 400-fpm velocities that don’t upset critical equipment intake and exhaust or room return-air-containment balances. It also offers the flexibility of directional spot-cooling capabilities with adjustable nozzles for high-wattage servers. DataSox features factory-engineered, energy-efficient ¼- to ½-in. wg of static pressure and results in cold-aisle temperatures 3 to 5°F lower than traditional distribution, but with up to 40% less CRAC flow rates, especially when complemented with VFD equipment. Using DataSox helps data centers achieve lower PUE levels, which makes it an ideal sustainability product for green construction projects.

Exhaust fan, stack assembly
The FumeJet pre-engineered exhaust fan with integral stacks is designed to safely remove and disperse fumes and odors. The FumeJet system replaces utility set fans with field-supplied intake ducts and exhaust stacks to ensure a safe roof-deck area and aid in preventing re-entrainment of contaminated air into air-intake systems. Benefits include single-source responsibility, performance data that includes stack and accessory corrections, energy savings by minimizing system effects, and features that reduce the cost of installation. The fan and stack assembly have been designed and factory-tested to withstand a force of 22 psf without the need for guy wires.
High-rise fan coil unit
The MiniReStoraMOD is a small high-rise fan coil solution. While ideal for hospitality, multifamily, and higher education applications, the MiniReStoraMOD is optimal for most high-rise retrofit projects as its size allows for it to fit into the shell of an existing unit. The replacement process is quick, easy, and cost-effective, minimizing the number of outside trades involved and eliminating the need to shut down entire rooms or floors for renovation. The result is reduced downtime, significant cost savings, and decreased revenue loss. The MiniReStoraMOD replaces most existing high-rise fan coils with energy savings and IAQ features, including an optional electronically commutated motor and closed-cell insulation.

The LG Multi V S is a single-phase variable refrigerant flow (VRF) 5-ton heat-recovery system. Ideal for light commercial installations including multi-use spaces, small eateries, and boutiques, this heat-recovery system is designed to provide excellent energy efficiency and the flexibility of simultaneous heating and cooling, even in the most extreme weather. For installation cost savings, the Multi V S only requires single-phase power, rather than the traditional three-phase, and can provide heat down to an outside temperature of -13°F.

Axial integral horsepower motor
The UlteMAX is an axial integral horsepower motor with a reduced length of less than 5 in. and an overall footprint reduction, resulting in it being 50% lighter than conventional radial motors. With this compact, flat, lightweight design, there is no longer a need to design around the motor. It can be intentionally hidden inside a much smaller system, requiring less space when installed. The UlteMAX motor’s three variable-speed axial horsepower motors provide the output to cut the average motor inventory in half. The UlteMAX motor allows for speed and horsepower configurations to cover a wide range of specifications without compromising system efficiency.

Floor-mounted indoor unit
The MFZ-KJ floor-mounted indoor unit features Multi-flow Vane Technology. This technology efficiently circulates air to quickly raise room temperature during cooler months. Multi-flow Vane Technology uses the lower portion of a multiflow vane to angle warm air into the return vent of the indoor unit, where it is re-circulated through the heat exchanger before being released into the room through the top portion of the multiflow vane. This process significantly reduces the time it takes to heat the room, ensuring superior warmth and comfort. The MFZ-KJ’s stylish, sleek panel suits a variety of aesthetics with minimal obtrusion.

Wall-mounted indoor unit
The MSZ-EF wall-mounted indoor unit can be used in combination with multizone technology, including the Hyper-Heating Inverter (H2i) systems that can deliver heat in even the coldest climates to create a Diamond Comfort System. Diamond Comfort Systems provide the ability to choose the desired temperature for each zone, while consistently using 30% to 40% less energy than traditional cooling and heating systems. The MSZ-EF features whisper-quiet operation with indoor fans functioning at a sound level lower than a human whisper, reduced energy waste with a weekly timer that allows up to four scheduling options, and intelligent temperature control with Econo Cool.
