MagnaClean Commercial Magnetic Dirt Filter
Adey introduces the MagnaClean Commercial Magnetic Dirt Filter for light commercial to heavy industrial applications. The patented magnetic filtration system starts to work immediately upon installation, removing virtually all of the suspended iron oxide that collects in hydronic heating systems. The magnet array has been redesigned to allow the magnetic rods to be lifted individually. This easy release sequence allows the magnetite from each rod to fall into the base of the filter body so it can be flushed out via the 1 1/4 -in. NPT drain at the base of the filter. Commercial filters are available in five inlet and outlet flange size options including 2 in., 3 in., 4 in., 6 in. and 8 in.
Evergreen Commercial High-Efficiency Boiler
The Evergreen commercial high-efficiency boiler from Weil-McLain features 96.5 percent combustion efficiency, a 10-to-1 turndown ratio, Smart Sequencing that balances the energy load across all system boilers, low NOx, a propane conversion kit, direct vent 100 ft. for intake and 100 ft. for vent a commercial-grade heat exchanger and non-metallic condensate base. Available in floor or wall-mount models. ZoneStacking controls allow up to 24 programmable zones without need for an additional panel. Ability to control multiple boilers with lead-lag capability without an external device. Available in models providing 220, 299 and 399 mbh.
Upgraded Crest Commercial Condensing Boiler
Lochinvar’s Crest condensing boiler family upgrade provides up to 96 percent thermal efficiency in six models ranging from 2.5 million to 6 million Btu/hr. for large commercial applications. The new models are manufactured with an upgraded combustion system and 316L stainless-steel heat exchanger. The fire-tube design transfers heat to surrounding water even more efficiently than before. The boilers feature an enhanced modulating burner that delivers a turndown ratio up to 20:1 and flexible flow rates up to 600 gal. per minute. The SMART TOUCH control system includes a built-in cascading component that enables communication and seamless sequencing of up to eight units.
Compact Sanineutral Kit
The Sanineutral neutralizer kit from Saniflo incorporates neutralizing granules to increase the pH of acidic condensate water produced in residential or commercial applications before it reaches the sewer line. Condensate produced by boilers, water heaters, air conditioners and other appliances moves through the compact unit, which neutralizes it to prevent the corroding of drains and sewer systems. It can be used without a pump, where the acidic condensate simply needs to drain through gravity or in conjunction with a condensate pump. The unit can rest on the floor, base or be wall-mounted. For appliances with higher Btu inputs that may require even more neutralization, it can be installed in series for increased performance.
Combination Boiler Feed, Backflow Preventer Valve
Taco Comfort Solutions
Taco’s brass boiler feed and dual check backflow preventer with atmospheric vent is designed for use in hydronic heating systems. It prevents heating system water from flowing back into the supply water piping if supply pressure falls below heating system pressure. It also offers simple pressure setting adjustment between 10 and 25 psi which is separate from the exclusive, lockable fast-fill lever. The valve is available in 1.2-in. cast-iron union sweat or union NPT feed valve with a brass backflow, as well as 1/2-in. and 3/4-in. brass union sweat or union NPT feed valve with a brass backflow.

Commercial Wall-Hung Fire-Tube Boiler
Navien’s NFB condensing, wall-hung, fire-tube boiler comes in two sizes — the NFB-175 and NFB-200 — both with an AFUE of 95 percent. The gas flow control system provides a 10-to-1 turndown ratio. Every boiler comes with a field conversion kit to switch from natural gas to propane gas. The Energy Star-rated boilers feature advanced controls with built-in hardware for connection to a boiler pump, three zone pumps or three zone valves. An optional SmartZone pump controller provides control for up to six additional zones. They have multiple venting options and materials along with exceptionally long vent lines, up to 150 ft. They also can be common-vented for up to eight units and cascaded up to 16 units.
G615 Cast-Iron Commercial Boilers
The G615 Cast-Iron Commercial Boilers from Buderus are designed to operate at any return water temperature. The Thermostream design increases efﬁciency and system reliability with no thermal shock. The full three-pass boiler design increases the heat transfer and efficiency of the boilers. Thermal insulation at 3 1/2 in. and 4-in.-thick decreases standby loss. The burner doors are ﬁeld adjustable to swing fully open from either side to enable the boilers to ﬁt in any location. They feature cast-iron breaching for long life and no refractory parts for reduced maintenance.
Commercial Steam Boilers
Triad Boiler Systems
Triad’s line of steam boilers is designed with a small footprint for tight mechanical rooms. They feature pressures of up to 150 psi, longer-lasting ﬁretube design that heats very quickly, a water-backed combustion chamber for very quick heat transfer, and Low-High-Low, modulating and dual fuel are available. When sequenced with a control panel, a highly eﬃcient system is created that assures the fewest number of boilers will ﬁre for the minimum required time.

PureFire Condensing Commercial Boilers
The Peerless PureFire commercial product line from PB Heat features gas-fired, stainless-steel condensing boilers with inputs of 399 to 1,500 MBH and thermal efficiencies of up to 96.6 percent. These cascade-ready boilers have a condensate system with built-in neutralizer and 120V convenience outlet. The larger sizes allow for common vent capability. The PFC-850 to PFC-1500 models are essentially two boilers in one cabinet, making them the perfect choice for jobs requiring cascading and redundancy. They offer a one-year parts-and-labor warranty and a 10-year limited warranty on the heat exchanger.
Commercial Wood-Fired Boiler
WoodMaster Commercial Series boilers give commercial heating systems the advantages of biomass heat. Features include automatic fuel feeding, ash extraction and sootblowing; boilers achieve 92 percent LHV efficiency using digital modulating-output control; ASME-certified pressure vessels, burns CO2-neutral wood fuel (such as wood pellet or chips). Models are available from 80 kW to 2,000 kW (up to 6.8 million Btu./hr.)
