Baltimore Aircoil Co. has announced a price increase of 3 percent on open cooling towers, 4 percent on all coil products, and up to 4 percent on parts manufactured in North America, effective immediately.
The Electric Coil Form machine is designed to produce bends in single-row coils or multiple single-row coils joined at one end. The machine handles round and flat-tube coils up to 60 inches wide and 3 meters long for large commercial HVACR applications.
Online coil selection software CoilPro is now available with new working fluids for the company’s full range of heat pipes. The fluids expand the range of operating temperatures for heat pipes from -30 to 200°C.
A heavy hurricane and tropical storm season may bring more corrosion damage to HVACR systems than we normally see. Now, as many contractors start to clean up systems, and others are scheduling preventive maintenance customers, coil care and corrosion prevention should be high on the work list.
Coils with insulated casings have been added to the company’s product capabilities. ThermiCoil™ insulated coils can be used for refrigerant and hydronic applications and can accommodate a wide range of airflows.
The condenser is the component that rejects the heat from the system. Most equipment is air cooled and rejects heat to the air. The coils are copper or aluminum and both types have aluminum fins to add to the heat exchange surface area.
Some years ago it was common for air-cooled condensers to develop leaks, resulting in unpredictable shorter service life. By studying the causes, it’s possible to come up with solutions. It became obvious that vibration was the major culprit, and thermal expansion/contraction creates some specific problems where the hot gas first enters the coil.
