Koelventilatorunit ROLINE 26.21.0271 — 19 inch ventilatormodule met 2 ventilatoren en thermostaat

ROLINE 26.21.0271 is a 19" cooling fan unit designed for installation in standard 19-inch racks and server cabinets. The module integrates two fans and an internal thermostat that adjusts fan operation according to ambient temperature, providing targeted airflow to reduce internal enclosure temperatures and support stable operation of network and server equipment. The unit fits into typical rack-mount openings and connects to standard power sources used in IT cabinets.

Advantages

The dual-fan arrangement offers increased airflow while maintaining compact rack space usage. The integrated thermostat enables automatic speed control, reducing noise and energy consumption when full cooling capacity is not required. The module is compatible with 19" enclosures and is designed for straightforward installation and replacement, helping maintain proper thermal conditions for installed hardware.

Suitable for

• Server racks and network cabinets in data centers and small server rooms
• Telecommunications racks and patch panel enclosures
• Industrial control cabinets with 19" mounting rails
• Environments where automatic temperature-based fan control is needed

Key specifications

• Form factor: 19" rack-mount fan module suitable for standard 19-inch enclosures
• Cooling configuration: two axial fans in a single module
• Temperature control: built-in thermostat for automatic fan speed adjustment
• Mounting: designed for installation in rack slots or fan tray positions
• Intended use: ventilation and thermal regulation for enclosed electronic equipment

How to use

Install the fan module into an available 19" slot or appropriate fan tray position in the rack, securing it with standard rack screws. Connect the unit to the cabinet’s power source following the enclosure and equipment power guidelines, and position cabling to avoid airflow obstruction. The integrated thermostat will monitor ambient temperature and adjust fan speed automatically; no additional manual control is required for basic operation. Periodically inspect the fans for dust buildup and confirm the thermostat responds to temperature changes to maintain effective cooling.

Recommendations

Place the fan unit in a location within the rack where it can draw cooler ambient air and exhaust warm air without obstruction. Maintain regular cleaning intervals to prevent dust accumulation on fan blades and grills, and verify electrical connections during scheduled maintenance. For racks with high heat output, consider combining this module with additional ventilation strategies such as blanking panels or increased airflow pathways to optimize cooling performance.
