Modular Tankless Water Heater Manifold Kits
The Ready-Link Modular Manifold Kits from Navien are available in configurations of two, three and four units side-by-side, and two and four units back-to-back. The kits are designed to save contractors time on multi-unit NPE tankless water heater installations or same-day emergency replacements. The kits can be picked up at the company’s wholesale locations and can be mounted either on a wall or in the Ready-Link rack system to support up to 16 cascaded units on 30 different arrangements.
Up to two kits can be combined as supplied to form a bank. To common vent the units, a common vent kit is required.
Multipurpose Work/Cargo Van
The 2018 Promaster multipurpose work/cargo van from Ram features a class-exclusive front-wheel-drive system with fewer parts to maintain; a standard cargo height of 65.4”; award-winning 3.6L Pentastar V6 engine; and electronic stability control with ABS, traction control, hill start assist and trailer sway control. With up to 49” openings on the sliding side doors and an over 60” doorway in the rear, all access points are wide enough to accommodate standard pallets.
Available cargo lengths are: 105.1” (1500), 122.8” (1500/2500), 145.9” (2500/3500) and 160.2” (3500).
Multi-Zone Controlled Chilled Beam Pump Module
This pump module from Semco is capable of controlling active chilled beams in up to five zones in commercial applications. It consists of onboard software, combination temperature/humidity monitoring sensors and thermostatically controlled hydronic valves.
Automatic Balancing Damper Series
Ruskin introduces a new series of pressure-independent automatic balancing dampers. The ABD-FD automatic balancing damper and curtain fire damper assembly combines an ABD with a UL555 1 1/2-hour static-rated fire damper to meet building code requirements. It automatically regulates damper positioning for precise and automatic airflow in supply applications. It also protects rated barriers, while providing constant balanced airflow.
Easy installation, with a sleeve assembly that fastens to the wall and requires no retaining angles. The unit’s tool-free CFM adjustment has up to 20 set-point positions. It features a unique-to-the-industry antimicrobial agent that mitigates the growth of mold and bacteria and contributes to improved indoor air quality.
AquaMotion’s circulator pump line of single- and three-speed PSC circulators reduce the cost and time of installation for contractors. Heating pumps AM7, AM8, AM10 and AMR are offered with a 10’ line cord and watertight cord connector to be wired into the control box. All ECM circulator pumps — Einstein SMART AM55 and AM99 circulators — already come with the 10’ line cord as standard.
All recirculation pumps — the AM1, AM3, AM6 and AM7 — are available with a grounded plug. Simply add the letter L after the product number. All products are UL-listed for this feature.
Dedicated Outside Air Systems
This new line of DOAS from York includes a range of 100% outside air units and mixed air units that provide users with more options and greater application flexibility. With heat-pump operation and water-source operation, as well as a hot water heat option, the new line of air systems delivers more combinations of heating and cooling than before.
The systems also feature an internal energy recovery wheel that pre-conditions outside air, and reduces heating and cooling loads by transferring energy between the exhaust airstreams.
