(UVDI) has been designed to specifically meet the needs of small unit systems, e.g., fancoil units, PTACs, unit ventilators, and heat pumps. V-Ray uses a UV output system that's electronically controlled (patent pending), and which was especially configured for 3/8 in. refrigerant tube coils of four rows or less, or for other applications where UV energy may be in proximity of discharge registers, etc., that could result in line-of-site exposure to humans.

SpacePak's PurePak, a patented electronic air filtration system that helps to protect against airborne allergens, bacteria, molds, pollen, smoke, fine dust particles, and VOCs, will be displayed at the Expo. The PurePak uses a patented carbon core filtration media system that absorbs odors and conducts an electrical charge that creates the polarizing field. The air-scrubbing combination of electrostatic polarization and activated carbon is 97% effective at capturing contaminants down to .3 microns. The PurePak system is available in three sizes and controlled by a thermostat fan setting.

Mars Air Systems, a manufacturer of air curtains and makeup air systems, will display a wide range of products from its Mars Air Doors, Dynaforce, and ARES divisions. ARES' packaged makeup air systems are designed to effectively provide comfort heating and cooling for an entire building or spot relief temperature and humidity control in difficult work areas. Air doors and curtains help maintain a clean comfortable work environment, protecting against dust, pollen, flying insects, wind, and extreme temperature conditions.

The Benchmark H21J Recip reciprocating compressor from Bristol requires no starting components, is specifically designed to optimize the performance of air conditioning systems rated 13 SEER and above, and features quiet operation. Benchmark divides its product line between the H21J Recip - which is suited for applications below 3.5 tons and the Benchmark Scroll, which is designed for larger applications.

The Fireye BurnerLogix is the next generation of single-burner controls, according to the manufacturer. Housed in a compact package having a smaller footprint, BurnerLogix offers many features and benefits for the commercial/industrial burner/boiler market.

Controlotron's unique clamp-on, non-intrusive 1010E energy meters are suited for energy distribution monitoring and the immediate analysis of energy efficiency with a real-time COP for HVAC systems. Features include real-time kW/Btuh and kW/gpm, transit time flow detection, built-in energy/Btu mode, and multiphase "Reflexor" mode to accommodate thermal energy metering and billing needs.

Selco/ECC has introduced the "Solid State Transformer" (SST) Model 399-0642 designed to replace conventional linear transformers with a highly efficient switching power supply. The SST fits a PC board transformer footprint and accepts a wide input voltage range of 75 to 305 VAC at up to 500 Hz, offering users optimum flexibility over a wide range of applications. The new SST uses much less power at no load than conventional transformers, says the company, and it provides energy savings and an improved safeguard against brownouts.

Designed for HVACR, mold prevention/remediation, and plant maintenance applications, Extech's series of psychrometers all feature simultaneous viewing of wetbulb, dewpoint, relative humidity, and air temperature in addition to various differential measurements. Each psychrometer includes protected sensors and built-in memory that can store up to 99 data points. All meters can also be field-calibrated using kit supplied calibration bottles. A built-in RS-232 interface utilizing Windows® Hyperterminal software allows downloading data to a PC for subsequent analysis.

Tekleen® filters from Automatic Filters, Inc., feature a fully automatic self-clean mechanism. They do not require any attendance and never interrupt the main flow. The filters range from 1 in. to 24 in. and are completely maintenance free, according to the company. The filters are designed to offer high-end, all stainless steel fabrication at carbon steel prices, ideal for cooling towers, chillers, condensers, spray nozzle protection, and drinking water applications.

The new Redi-Purge Model HPP-3 (Nema-4X) by Redi-Controls, Inc., extends its HPP-3 line of non-condensable purgers for high-pressure refrigerant (R-12, 22, 134a, etc.) systems allowing for corrosion-proof environment applications. Eliminating non-condensables from a refrigeration system allows for efficient operation, as industrial process cooling applications often experience decreased capacity due to non-condensable buildup. The HPP-3 Series of Redi-Purgers assist in maintaining efficient chiller operation.

Nicholson Steam Trap will introduce its universal mount steam trap technology product family consisting of the "Big Block" universal mount steam trap test station and its universal mount UMT and USBT Series thermostatic, thermodynamic, and inverted bucket steam traps.
