Aerospace wire

TYCO ELECTRONICS. HARRISBURG. PA. Raychem brand SPEC 55 low fluoride aerospace wire and cable is an advance for aerospace electronics designers since low-fluoride XL-ETFE wire was not previously available to the industry. Minimizing fluoride levels in aerospace wire is very important since fluoride may evaporate from traditional XL-ETFE wire insulations, combine with moisture, and result in a corrosive substance. Corrosion in the proximity of wire, cable, and electronics does not bode well for reliability, long life, or performance of sensitive aerospace electronics. In addition to satellite, missile, and aircraft applications, SPEC 55 low-fluoride wire and cable can be used in test and measurement equipment and other sensitive electronic equipment. According to the company, there is also benefit to assemblies stored in sealed bags for long periods of time.

Split systems

LENNOX INDUSTRIES INC.. DALLAS. TEXAS. Lennox now has two new versatile 3- to 5-ton commercial split system air conditioning and heat pump units. Both the T-Class TS/TPA and the S-Class SS/SPB models are available with R-410A refrigerant and offer a variety of features to help increase efficiency and ease of installation and maintenance. The T-Class TS/TPA line of air conditioners and heat pumps is designed to help achieve comfort and energy savings. The new R-410A model includes high-quality components and complements the existing R-22 product line, adding more choices and options for customers anticipating the phase-out of R-22 refrigerant in the upcoming years. The energy-efficient design features high-efficiency scroll compressors and outdoor coils that provide good heat transfer and operation. Available with chlorinefree R-410A refrigerant, the new S-Class SS/SPB air conditioners and heat pumps are designed to help create a better indoor environment while reducing energy bills. The new S-Class SS/SPB split system is said to be one of the most energy-efficient commercial split systems. The S-Class SS/SPB features a two-stage compressor, reducing temperature swings while providing the right amount of cooling, dehumidification, or heating.
