Fully modulating boiler

The Benchmark 1.5 is a low-nitrogen-oxide (NOx), condensing, fully modulating boiler useful for projects requiring 1.5 million Btuh. It delivers 20-to-1 turndown ratio and is designed with a low-NOx burner for applications requiring minimal emissions.

Condensing boiler

The 94-percent-efficient ModCon commercial condensing boiler features an Inconel load-matching gas burner with a 5-to-1 turndown ratio to meet variable needs for space heating and domestic hot water in a single application. For example, the 500,000-Btuh model can operate as low as 100,000 Btuh, saving energy on warmer spring and fall days when the heating load is light.

Copperfin boiler

A near-condensing copperfin boiler, the Futera XLF offers 4 million Btuh and up to 88.5-percent efficiency. Approximately 29-in. wide and 69-in. high, the gas-fired boiler utilizes HeatNet technology, an onboard digital monitoring and control device.

Heat-recovery system

The BDHR blowdown heat-recovery system maximizes boiler efficiency by capturing energy from continuous blowdown flow and generating low-pressure flash steam. Its configuration allows several boilers to be connected to a single heat-recovery unit.

Air-Filter-Performance Brochure

A brochure from Camfil Farr describes green air-filter performance in terms of energy savings, air quality, waste reduction, and environmental impact. Also discussed are methods of comparing filters, including life-cycle-cost analysis, in-situ testing, and the CamTester, a mobile unit that measures energy used by any manufacturer's air filter.

Fan-Coil Units

Four-way ceiling-mounted cassette fan-coil units from Daikin AC are designed to fit flush into a standard 2-ft-by-2-ft architectural ceiling grid. These compact fan coils can be combined with Daikin's VRV outdoor condensing units, the VRV-S, VRV III, and VRV-WII. Cooling capacities are rated up to 18,000 Btuh, and heating capacities are rated up to 20,000 Btuh.

Plenum Fans

Model QEM plenum fans are useful for lower-pressure supply or return air-handling applications in which first cost is critical. The fan features a 12-bladed airfoil wheel that reduces energy consumption and sound levels.
