The NEWS was very busy at the AHR Expo in New York City, visiting as many booths as possible in search of new products. Below is a comprehensive list of all the HVAC commercial equipment we found on the show floor.

Aerco Intl. Inc. displayed its AM Series modular boilers, which have a unique modular design that provides fuel savings from 399-1,000 MBtu. Each unit is comprised of between two and four independent thermal modules firing up to 250 MBtu, each at 5:1 individual turndown. This allows for optimum temperature control and low-cycling operation. When needed, multiple units can be colocated and common vented to provide a boiler plant with highest efficiency, turndown, and redundancy in a small footprint.

Aerosys Inc. exhibited its AeroPak Series of through-the-wall heating and cooling units. The compact, completely self-contained package allows each tenant or condo owner to have complete control of his or her comfort needs. The AeroPak can be specified in three combinations: gas heating/electric cooling, electric heating/electric cooling, and heat pump. Features include field-switchable (slide out) heat options, 9.0 EER cooling efficiency or higher, internal vent system (direct vent), R-410A refrigerant, slide-out cooling chassis, heavy-gauge stainless steel condensate pan and fitting, and fully insulated cabinet for quiet operation. Also, Aerosys displayed its THDC line of through-the-wall split system condensing units, which are rated at 14 SEER and are designed to meet demanding requirements for multifamily housing.

Ajax Boiler Inc. introduced the Triton Series™ high-efficiency boiler, which offers a cost-effective solution for space heating and process hot water applications. Features include compact modular design, high-efficiency performance, low emissions, advanced controls, easy start-up, and convenient operation. The foundation of this boiler consists of a double-row, high-finned, copper-tube, four-pass, water-tube heat exchanger. This configuration produces the greatest heating capacity in the most compact package, while maintaining high efficiency ratings, and NOx emissions of less than 9 ppm.

Aquatherm Polypropylene Pipe displayed its Aquatherm Black System. The system radiates heat directly from thermally controlled walls or ceiling to occupants. Large thermal surfaces allow for a lower operating temperature (77?-95?F for heating, 50?-65? for cooling), making the system ideally suited for use with eco-friendly condensing boilers or alternative energy sources like heat pumps, solar water heaters, geothermal, and heat-recovery systems. The system is rated at 30 Btu per square foot with 100? water and 70? room temperature for heating. In cooling applications, panels are rated at 30 Btu per square foot with 55? water and 75? room temperature. System advantages include no drafts, reduced noise, dust reduction, minimal construction thickness, and more.

Armstrong Intl. Inc. exhibited its EHU-800 electrode humidifier. According to the company, the EHU-800 is ideal for providing humidification where no steam is available or where a steam source is too remote for easy or economical piping. The humidifier converts ordinary tap water to steam and distributes it to bring the relative humidity up to the desired level. Features include a digital display with keypad, native Modbus, external water and drain connections, external fill cup, cleanable and/or replaceable tank, onboard controller, relay to control external fan package, and an optional relay board. The Series EHU may also be used in combination with an Armstrong EHF-2 or EHF-3 fan package for direct area discharge of steam.

Atas Intl. Inc. showcased the InSpire transpired solar collector for heating fresh air. The InSpire wall panel is mounted a few inches from the building’s outer wall. The precision perforations in wall panels allow outside air to travel through the face of the panel. Solar-heated air at the surface of the panel is drawn through the perforations where it rises between the two walls and enters the building’s central ventilation system, or supply fan. The InSpire wall panel also helps to reduce the cooling load in the summer by preventing normal solar radiation from striking the building’s main wall. Hot air is thermally siphoned up the wall and vented through holes at the top of the system, leaving the main wall cooler. In the summer, bypass louvers allow cool, fresh air to be drawn into the building at night, maintaining IAQ.

Baltimore Aircoil Co. Inc. featured the Series 300 Cooling Tower, which exceeds ASHRAE 90.1-2013 energy-efficiency requirements. It is also said to have expanded flexibility and enhanced payback analysis tools.
