    A boundary layer film of air adhering to the fin surface will insulate the fin surface and severely reduces the heat exchange efficiency. MCQUAY slit fin design eliminates this boundary layer of air and creates continuous turbulence for best heat exchange efficiency.
  • Page 6 Caution 1. The temperature of the surface of PTC heater may be over 200°C if the power of unit is on but the fan of the unit is not running. Don’t touch the unit at this time! 2. The starting current of the unit is more than its working current. It should be considered both the working current and starting current while choosing the fuse.
