Benefits & Features

High-quality Manufacturing
  • Coil tubes are round, seamless copper which mechanically expand into the fin collars, providing a permanent metal-to-metal bond for efficient heat transfer.
  • Coil tubes are staggered in direction of airflow.
  • Fin collars are fully drawn to provide accurate control of spacing and maximum contact with the tubes.
  • Headers are seamless copper with die-formed holes that provide a parallel surface to the tube for strong brazing joints.
  • Coils are submerged under water and then pressurized with air to check for leaks.
Certified Performance
  • AHRI Certified to Standard 410 — giving you the confidence that your coils will perform as promised.
  • AHRI Certified coil performance can be useful during verification for LEED® or other building certification programs.
  • Variable casing dimensions, fin spacing, copper tube thickness, and a variety of casing and fin materials, including copper fin and stainless steel casings for coils in corrosive atmospheres.
  • Protective coatings and treatments available to extend the service life of coils installed in corrosive atmospheres — fins, tubes, headers, and casing are completely coated.
