Cooling fan TECHLY I-CASE FAN-TC2B — 2-fan AC rack accessory, 483×220×44 mm

TECHLY I-CASE FAN-TC2B is a rack-mounted cooling fan unit with two black axial fans, designed to fit standard 19-inch enclosures. The unit measures 483 × 220 × 44 mm and is powered from AC mains (220–240 V, 50–60 Hz). It provides active ventilation to improve airflow inside server cabinets, network racks and equipment enclosures, helping to reduce internal temperatures and support reliable operation of installed hardware. The accessory also includes a universal single-sensor temperature controller with cooling function, alarm output for temperature thresholds and an adjustable ventilation delay to coordinate fan operation.

Advantages

The dual-fan configuration delivers increased airflow compared with a single-fan module while maintaining a compact 1U-compatible profile for shallow mounting depths. AC mains operation eliminates the need for DC power supplies in many installations, simplifying integration into existing rack setups. The integrated temperature controller enables automatic activation of the fans according to measured temperature, with an alarm output if programmed limits are exceeded. The adjustable delay feature allows controlled start/stop behaviour to avoid unnecessary cycling and to coordinate with other cooling devices.

Suitable for

• 19-inch server cabinets and communication racks
• Network equipment enclosures and patch panels
• Small data closets and telecom cabinets
• Electronics housings requiring forced ventilation

Key specifications

How to use

Mount the unit in a standard 19-inch rack space, securing it with appropriate rack screws or cage nuts. Connect the fan unit to an AC mains outlet rated for 220–240 V, 50–60 Hz and route the temperature sensor to the location representative of the equipment temperature you wish to monitor. Program the temperature controller set points and the ventilation delay according to the thermal characteristics of your racked equipment. Verify that the fans start automatically at the set temperature and that the alarm output operates when thresholds are exceeded.

Usage recommendations

Place the temperature sensor at a mid-rack position near the hottest equipment to obtain accurate control. Avoid obstructing fan intakes and exhausts; provide clear airflow paths into and out of the cabinet. Use the adjustable delay to prevent short cycling when intermittent heat loads occur, and regularly inspect the fans for dust buildup to maintain optimal airflow.
