Electric radiant heaters are one of those technologies that seldom get a glance from me. And maybe that''s why I was attracted to this exhibit. I didn''t see anything I recognized. I walked over to see what those black crates were that BBC Industries was exhibiting. They didn''t look like much, and then the radiant heat hit me. Thermazone Black Body radiant heaters are simple, unpretentious and are available in sizes from 450 watts to 6,000 watts.A former employer of mine, Novar Controls Corp., shocked me out of my shoes with its exhibit. The old Tesla coil spark machine was gone but Novar''s entire line of building controls has undergone a complete redesign, which includes attractive packaging, enhanced communications and new product names. In particular, the product renamed Lingo can now converse with almost all manufacturers'' equipment in their own protocols, including Lon Works and BACnet.

Most air-cooled products (including chillers, rooftop units, and condensing units) use DX evaporators. Most DX systems allow oil to travel through the refrigeration circuit and woodschippershredderprice back to the compressor oil sump. Great care must be taken during design woodschippershredderprice to provide oil return, particularly at part load, when refrigerant flow rates are reduced.Water-cooled chillers often use flooded evaporators. In a flooded evaporator, even small amounts of oil can coat evaporator woodschippershredderprice tubes and significantly diminish chiller performance. This can lead to an elaborate woodschippershredderprice oil-recovery system. Magnetic bearings eliminate the need for these systems and oil management in general. In fact, the only required regular maintenance of the compressor is the quarterly tightening of the terminal screws, the annual blowing off of dust and cleaning of the boards, and the changing of the capacitors every five years. Complete service agreements and extended maintenance contracts can be provided by the manufacturer.
