The new tubing offers flexibility, durability, corrosion-resistance, proven history, and a 25-year limited warranty. With the 3-inch PEX, professionals don’t need to switch products when installing potable systems for both small- and large-dimension applications. The 3-inch tubing uses WIPEX™ dezincification-resistant (DZR) brass fittings. The fittings require the use of a simple chamfering tool, a pair of WIPEX Sleeve Pliers, and a wrench to create solid, strong connections in minutes.
Viega (www.viega.com) featured Climate Mat®, the newest offering in the company’s ProRadiant® line. Instead of manually laying, tying, and suspending individual lengths of tubing, the product allows installers to roll out the mat and pour a 4-inch concrete slab directly on top of the tubing without typical reinforcements. Suited perfectly for large, preferably rectangular or square slabs typically found in warehouses or airport terminals, the mat allows installers to lay up to 20,000 square feet of tubing for radiant heating or cooling in eight hours.

According to the company, ultraSchwank provides the most uniform heat distribution, reduces convection heat losses, and directs more heat where it is required. Minimum clearances to combustibles are reduced by 50 percent. It is said to be the first tube heater designed with an insulated reflector system. It increases tube and inner reflector surface temperatures, for superior heat retention and greater comfort at lower air temperatures. The clam shell housing design provides easier access to heater components.
Space-Ray Infrared Heaters (www.spaceray.com) displayed its recently introduced PTS/PTU Series push through low intensity infrared tube heaters using positive pressure with its patent-pending Tube Integrity Safety System™ (TISS) that provides building owners with the ultimate in fire safety protection, says the company. With the TISS system, an insulated wire is placed above the reflector. A low voltage circuit control continuously monitors the clearance between the reflectors and the ceiling for excessive heat and tube integrity compromise. If the heat increases due to heat exchanger failure, the wire melts, the safety circuit is broken, and the gas controls shut down.
The Superior Radiant Products (www.superiorradiant.com) Premier VS-VH Vacuum System is a high-efficiency infrared radiant heating system. Thermal efficiencies of up to 94 percent can be achieved depending on the configuration. According to the company, the state-of-the-art Premier VS-VH complements the company’s Premier VS with smaller in-series burners, offering greater layout flexibility.

Honeywell (www.honeywell.com) reported on the development HFC-407F (marketed as Proformax LT) designed for retrofits of R-22 in low temperature applications. The company also reported on continuing work on HFO-1234yf with the possibility of the alternative to HFC-134a being introduced to the European automotive market beginning with the 2012 model year. The potential for R-1234 being used in stationary applications also continues to be explored.
ICOR International (www.icorinternational.com) offers an alternative to R-22. HFC-422B is marketed by the company as NU-22B®. The company described the refrigerant as one of the safest and most practical options. NU-22B closely matches R-22’s operating characteristics, is ASHRAE designated and safety classified A1. NU-22B is available through stocking wholesale distributors nationwide.
REFRIGERANT-RELATED TECHNOLOGIESCliplight Mfg. (www.cliplight.com) has introduced Flash™, a new class of ultra violet (UV) leak detection dye.

Packaged in a vacuum-packed “one-time use can,” Flash uses Cliplight’s injection hose coupled with Dry R, allowing the dye to mist into the system for instant distribution.
Idemitsu Lubricants America (www.pag-idemitsu-usa.com) has a polyvinylther (PVE) oil to be used instead of POE oil in HFC equipment. According to the company, “The chemical chain on our PVE oil shows similar characteristics to mineral oil with both good lubricity and similar dielectric strength. In addition, the chemical structure’s side chain has characteristics of PAG oil, with good solubility and no hydrolysis.”
Neutronics’ (www.neutronics.com) Ultima ID Model RI-700H is a portable analyzer that identifies the type of refrigerant and helps avoid costly refrigerant mixing during consolidation and reclamation, the company said. It works on a variety of refrigerants, including HCFC- 22, and the HFCs -134A, -404A, -406A, -407C, and -410A as well as hydrocarbons. The manufacturer said it reduces the need for gas chromatography and delivers results in less than three minutes at an accuracy of +/-2 percent or better. According to Peter Coll, refrigerant analysis division manager for Neutronics Inc., “As new refrigerants are introduced to the market, the potential for mixing those refrigerants with the R-22 supply will increase and usher in a financial penalty that will affect all levels of distribution, from the contractor to the reclaimer. The Neutronics Ultima ID Pro HVAC/R Refrigerant Analyzer will help solve this problem.”
SPX’s (www.spx.com) Promax RG6000 refrigerant recovery machine has been engineered to deliver the fastest overall ARI-740 certified refrigerant recovery rates in most conditions within a small portable unit, the company said.
