The redesigned Benchmark 3000 (BMK3000) boiler features a high 15:1 turndown for energy efficiency in a compact footprint. The BMK3000 is suitable for both retrofit and new-construction applications that require one or multiple 3-million-Btuh boilers. It has an operating efficiency of 93.5 percent and a footprint 22 percent smaller than that of the previous 3-million-Btuh model and 50-percent smaller than that of other condensing firetube boilers of the same capacity. —AERCO International Inc.

Ultrahigh-efficiency boilers
Triple-Flex ultrahigh efficiency condensing boilers feature flexible stainless-steel tubes and minimum thermal efficiency of 90 percent with 160°F return and 180°F supply at maximum input. Efficiencies of 99 percent are achievable with lower return-water temperatures. —Bryan Steam

Watertube boilers up to 600 hp
Cleaver-Brooks’ flexible watertube boiler is available in models of up to 600 hp for hot water and steam with less than 9-ppm NOx. It is 81-percent efficient on high-pressure steam and 85-percent efficient on hot water. The factory-built or field-erectable package is available with an integrated dual-fuel burner from a single source. —Cleaver-Brooks

Condensing boiler
The MACH C4000 condensing boiler is designed to lower fuel bills, reduce emissions, and decrease installation costs. Equipped with an aluminum heat exchanger and the exclusive ENVI control, the boiler produces 4-million-Btu input at 95-percent efficiency, with a thermal efficiency of up to 99 percent. —Harsco Industrial

Flow Switch
The Series V7 Flotect flow switch is an inexpensive switch for use with compatible liquids to start or stop electronically operated equipment when flow or no-flow conditions occur. Magnetic operation is simple and dependable with no mechanical linkages or seals to wear or leak. The vane design is rigid and field-trimmable for setpoint adjustment. —Dwyer Instruments

Flue-gas economizer
The EcoFlex 90+ system packaged fan-powered flue-gas economizer can be installed in any part of a chimney, horizontally or vertically. It can be used in conjunction with any gas-fired heating appliance and is suitable for use with draft-hood- and draft-diverter- equipped heating appliances. —Enervex

Combustion control system
The NEXUS PPC4000 parallel-positioning combustion-control system is comprised of a main controller, flame safeguard, servo motors, O2 sensor, and variable-frequency drive. It is designed to replace existing mechanical-linkage fuel/air controls and reduce fuel costs by optimizing fuel-to-air-ratio control. —Fireye Inc.

Integrated control systems
High-efficiency integrated control systems for boiler-room monitoring and communications provide advanced supervisory boiler controls for all new and legacy Hurst products. The comprehensive line of control systems features graphical visualization and information collection to facilitate operational management of boilers and supporting peripherals. —Hurst Boiler

High-efficiency water heater
The Ilios high-efficiency water heater (HEWH-500-AS) runs on a natural-gas engine. It extracts energy from the atmosphere, pumping it to a useful temperature using a standard vapor-compression refrigeration cycle. Free waste heat from the engine is recovered, adding to the unit’s capacity and efficiency. The Ilios HEWH output is nominal 500,000 Btuh and suitable for facilities with a gas demand of 2,000 therms or more per month. —Ilios Dynamics

Pressurized deaerator
Counterflow-tray deaerators from Industrial Steam remove dissolved oxygen in excess of 0.005 cc per liter from 5 percent to 100 percent of deaerator capacity. Electronic instrumentation for modulating deaerator level control includes a HART-compatible differential-pressure transmitter, proportional–integral–derivative controller, and motorized control valve. —Industrial Steam

Light-commercial boilers and water heaters
Keystone condensing boilers and water heaters are available in five models from 399 to 850 mbh. The units feature a high-efficiency, condensing, stainless-steel heat exchanger and sealed combustion design that provides thermal efficiencies of 95 to 97 percent. —Triangle Tube

Space-saving hydronic solution
The NeoTherm LC condensing boiler is a fully packaged, 1-million-Btu, space-saving hydronic solution that offers 94-percent thermal efficiency. The direct-vent, sealed-combustion boiler modulates with a 10:1 turndown. The unit includes Laars’ integrated control system with proportional–integral–derivative logic that governs ignition, outlet-water temperature, indirect water-heater functions, and outdoor reset; stages up to four boilers; and easily integrates with building automation systems and other controls for boiler sequencing. —Laars

Firetube condensing boiler
The CREST firetube condensing boiler is now available in inputs of up to 5 million Btuh. The fully modulating boiler features a low-NOx combustion system with a stainless-steel heat exchanger and a patent-pending dual-system burner with up to 25:1 turndown. The unit is capable of thermal efficiencies as high as 99 percent. —Lochinvar

Intelligent boiler-control technology
The RBT-3000 low-water cutoff and fuel economizer is designed to maximize fuel efficiency and provide valuable low-water cutoff protection for hydronic heating systems. The intelligent controls built into the device bring advanced microprocessor technology to virtually any boiler, automatically adjusting water temperature based on heat load without the need for an outdoor sensor. —McDonnell & Miller

Hydronic boilers
The NH150-DV and NH199-DV tankless hydronic boilers are designed to provide constant room temperature for various heating choices, including panel radiators, baseboard flooring, and radiant-floor heating. The direct-vent units feature a gas-consumption range of 55,500 Btuh to 150,000 Btuh for the NH150-DV and up to 199,900 Btuh for the NH199-DV. —Noritz
