Easy PP-R-to-PEX transition

Aquatherm’s new polypropylene-random (PP-R)-to-PEX transitions come in ½-in., ¾-in., and 1-in. sizes and are designed to make it easy to design and install Aquatherm systems that integrate PEX tubing. The transitions, which are made from PP-R and brass, are heat-fused to Aquatherm pipe on one side and crimped to PEX pipe on the other. They meet ASTM F1807 specifications, connect seamlessly to standard Imperial PEX sizes, and are designed to reduce cost and the risk of leakage by eliminating a threaded connection in the transition to PEX.

Pressure-independent control valve

The Energy Valve is a two-way, pressure-independent control valve that optimizes, documents, and proves water-coil performance. It uses Belimo Delta T Manager algorithm to directly control air-handler-unit-coil performance. It monitors the coil performance characteristic curve and resulting energy/power output. The actuator calculates and stores all coil-performance data, such as delta-T and energy usage. Performance data, stored trends, and control functions can be sent to and from the building-automation system via the data network to optimize coil and system performance.

Ultrahigh-efficiency boilers

Triple-Flex ultrahigh-efficiency condensing flexible-water-tube boilers offer guaranteed minimum thermal efficiency of 90 percent, even in worst-case condensing-boiler operating conditions, such as 160°F return water and 180°F supply water at maximum input. Efficiencies of 99 percent are achievable with lower return-water temperatures. Triple-Flex boilers fire at 1,500- to 3,000-mbh input, with sub-30-ppm NOx levels utilizing a hybrid metal-fiber 5:1-turndown burner and Honeywell SOLA hydronic safety controls and interface systems.

Condensing hot-water boiler

The ClearFire-LC (CFLC) gives large facilities a condensing-hot-water-boiler option from 4,000 to 12,000 MBtu. The CFLC uses patented AluFer heat-transfer technology and a high-turndown burner with advanced controls to deliver peak efficiency and ultralow emissions in a compact footprint. The CFLC is a cost-effective alternative to installing multiple smaller boilers or less-efficient, non-condensing boilers of similar capacity. Installing a CFLC large condensing boiler can reduce a facility’s operating costs by up to 50 percent compared with a traditional steam or hot-water system.

Firetube wet-back boiler

The Euro Series three-pass firetube wet-back boiler features a full wet-back radiant heat-transfer area that promotes superior internal water circulation and rapid heat absorption. It is available in eight models from 100 to 2,000 bhp, in steam or hot water, and in oil, natural gas, or combination. Separate rear tube sheets allow each pass of tubes to expand and contract at its own rate without tube-to-sheet stress. Tubes are mechanically rolled, flared, and beaded to simplify tube service.
