Lochinvar’s commercial CREST outdoor boiler
Lochinvar’s CREST Condensing Boiler line now has six models ranging from 750,000 to 2 million Btu/h optimized for outdoor commercial installations. The more compact units offer a significant space savings for large public and commercial facilities like school systems, universities and libraries. The option to install the unit outside adds more than 200 usable square feet to any space. These models also feature a 96 percent thermal efficiency rating. The models come standard with the CON•X•US remote connectivity platform, which allows commercial facility managers and building owners to monitor and adjust equipment controls from a mobile app available on most smart devices. As many as eight CREST boilers can be cascaded together for redundancy to provide reliable performance, even if units are offline for maintenance. 615-889-8900; www.lochinvar.com.

WexCo Environmental Filtrol 160 washing machine lint trap
The Filtrol 160 from WexCo Environmental is the first washing machine lint trap capable of capturing microscopic fibers and keeping them out of septic systems. It also filters out hair, microplastics, pet hair, concrete particles, metal shavings and sand, all of which, like fabric fibers, can accumulate in a septic drainfield, drastically reducing its ability to help filter the wastewater that is deposited in the septic tank. 888-983-2447; www.septicsafe.com.

Caleffi North America 574 Series backflow preventer
The new 574 Series testable, reduced-pressure zone backflow preventer from Caleffi North America is used in residential and commercial plumbing systems where ASSE 1013-type devices are required by code. The 574 Series prevents accidental contamination of the distribution water supply system when there is a reduction in pressure in the supply system, like a main break or periodic flushing, or an increase in pressure in the building plumbing system, like a missing or nonfunctioning domestic hot-water expansion tank. 414-238-2360; www.caleffi.com.

Armstrong Fluid Technology COMPASS R stainless steel circulator
Designed for use in potable water systems, the new stainless steel COMPASS R circulator from Armstrong Fluid Technology features a dry rotor design, as well as advanced variable speed Design Envelope technology, Armstrong iECMTM motors, and quadratic control to minimize both energy costs and long-term operating costs for homeowners. The quadratic control algorithm offers operating efficiencies that are better than standard variable-speed solutions, and even greater system energy savings are possible with the 0-1 volt DC input signal connection to external systems. The circulator is a bolt-to-bolt match for many installed circulators.
