Key features of the ACUB

  • Three sizes, works with CAUA sizes: 150 & 200
  • Nominal cooling capacity range - 90, 120 or 150 MBH
  • Airflow range - 3000 to 5000 CFM
  • Coils can be directly matched to Reznor model MASA condensing units


  • All coils include a factory-matched and installed thermal expansion valve for R-410A refrigerant.
  • The expansion valve ensures proper operation of the coil over a wide range of design conditions. Use of an expansion valve eliminates problems such as compressor flooding and evaporator coil frosting that are often encountered with fixed orifice expansion devices.
  • In addition, the coils employ an interlaced circuiting design which provides a more efficient use of the coil surface than other circuiting techniques.
