Engineered Systems - January 2009 - (Page 38) FLOORED! mounting bracket rotates 360° to accommodate any mounting orientation. DuctSox® will exhibit UnderFloorSox™ (UFSox™), an air dispersion system designed HEAT PUMPS ClimateMaster offers its Tranquility 16™ Compact (TC) Series water-source heat pumps with EarthPure® HFC-410A zeroozone-depletion refrigerant. It is extremely environmentally friendly, boasts a small cabinet, is compatible with thousands of older water source heat pumps, and utilizes scroll compressors to exceed ASHRAE 90.1 efficiency requirements. The series is available in sizes from 1¼ to 5 tons and is geothermal-capable. HEATERS Space-Ray Infrared Heaters will show a new line of positive pressure, low-intensity tube heaters with patent-pending Innovative DuctSox's UnderFloor Sox™ air dispersion system reduces thermal decay in plenum UFAD systems. DRI-STEEM's line of microchannel heat exchangers are designed to reduce refrigerant charges by as much as 40%. to reduce thermal decay and improve temperature consistency within the plenum UFAD systems for retrofits and new construction. In applications, the system features a modular configuration as active linear dispersion sections to uniformly mix the supply and plenum air, which minimizes diffuser adjustments to maintain set point temperatures throughout the occupied space. This ensures the occupied space’s partial displacement temperature gradient remains stable. Space-Ray's Infrared Heaters' positive pressure, low-intensity tube heaters feature the Innovative Tube Integrity Safety System™. Tube Integrity Safety System™ (TISS). The heaters are available in eight models and over 100 different configurations, and the new PTS/PTU Series tube heaters have capacities ranging from 40,000 Btuh to 200,000 Btuh and minimum mounting heights of 10 to 18 ft. The heaters are suited for retrofitting existing push through systems and are certified for vented (sidewall or through the roof venting) or indirect vented operations, depending on application requirements. HEAT EXCHANGERS Danfoss has expanded its portfolio of heat exchangers with the introduction of the company’s own range of microchannel heat exchangers through its joint venture, Danfoss Sanhua. Microchannel heat exchangers have been used for more than 20 years by automotive manufacturers who wanted efficient heat exchange in a compact design. With the microchannel heat exchangers, the company reports systems that reduce refrigerant charges by as much as 40%. Also, high efficiency makes it possible to achieve the same effect in a smaller system, thereby reducing total system costs. for their Ultra-sorb steam dispersion panels. Model XV combines the proven energy savings of high-efficiency tubes with a condensate management. The innovative design utilizes high-efficiency dispersion tubes to reduce condensate production, heat gain, and wasted energy; employs the heat and pressure of existing boiler steam to vaporize dispersion-generated condensate; returns an equal volume of pressurized condensate to the boiler; and does not waste condensate to the drain. PIPING / COUPLINGS / SUPPORT Aquatherm will exhibit its piping and insulation systems, including its Advanced pipe wrap insulation. Traditional systems require 1 to 1½ in. fiberglass insulation to achieve Aquatherm's piping and insulation systems allow for installation in tight spaces. ClimateMaster's Tranquility 16™ Compact (TC) Series heat pumps feature EarthPure® HFC-410A refrigerant. HUMIDIFICATION DRI-STEEM brings what it calls another energy and water efficiency breakthrough the same R-value ratings as the Aquatherm Advanced piping system. The reduced diameter of this insulated pipe is designed to allow for installations in much tighter spaces than metal/fiberglass combinations. 38 En gi neer ed S y stem s January 2009
