  • PROTEK Single-Door Fan Package cabinets are an excellent, off-the-shelf choice for mounting 19-in. rack, panel-mounted devices or other electronic equipment. An integral top solar/drip shield and thermostatically-controlled fans provide airflow to cool internal equipment. Cabinets are available in UL Type 3R for indoor/ outdoor use. A UL Type 1 window-door version is available for indoor applications. The integral fans provide cooling for internallymounted equipment. The enclosures provide protection against water, dirt and other contaminants. PROTEK is an excellent choice for applications where space is at a premium and the only option is wall mounting. PROTEK comes in a broad range of sizes, materials and configurations to meet many demanding applications.


  • Performance data based on:
  • Effective measured airflow provided by integral fans is 272 CFM (6-in.) or 113 CFM (4-in.)
  • Delta T or ΔT (Ambient Temperature – Maximum in-cabinet Temperature)
  • Ambient air must be cooler than maximum in-cabinet temperature
  • For applications that have less than a ΔT of 5 F, use PROTEK with AC unit
  • Total Cooling = (Air cooling + Cabinet cooling)
  • Air Cooling [Watts = .316 x CFM x ΔT] Cabinet cooling [Watts = (.22 x Area) / ΔT]
  • Example: Cabinet height 24 in. x 24 in. deep with ambient temperature 110 F, with a maximum internal cabinet temperature 120 F (ΔT = 10 F). The cabinet and fans will provide a total cooling capability of 762 Watts or 1300 BTU.
