PROTEK™ Single-Door Fan Packages

Return to Product Index


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 internally-mounted 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.
