The fan unit from Vertiv, type Knürr® fan unit, is a 1 U component for vertical ventilation of modules in 48,3 cm ( 19 inch ) racks. It supports targeted air circulation within server or network racks to assist in cooling sensitive electronic components. The unit is designed for an operating voltage of 230 V and features a thermostat-controlled fan function adjustable between 0 °C and +60 °C. This allows the fan activity to be adapted to the actual temperature inside the rack, enabling efficient and energy-saving cooling.

Applications

The fan unit is specifically designed for use in 48,3 cm ( 19 inch ) racks where targeted airflow is required to ensure effective heat dissipation from installed modules. It is particularly suitable for racks with high density of electronic components, where passive cooling is insufficient. The vertical ventilation supports natural airflow and prevents local overheating. The unit is intended for use in IT infrastructures, server rooms, and other technical installations where controlled temperature regulation is necessary.

Functions and Equipment in Detail

The fan unit is supplied with a 2 m long connection cable designed for connection to a grounded socket. The fan function is thermostat-controlled and can be adjusted within the range of 0 to +60 °C, ensuring the fan is only activated when the set temperature is reached. This ensures energy-efficient operation and reduces unnecessary noise. The front trim panel is powder-coated in RAL 7035 light grey, enabling clean visual integration into existing rack environments. The housing is made of galvanized steel sheet, providing high mechanical stability and corrosion resistance.

Technology Explained Simply

The fan unit uses an electric fan controlled by a thermostat. The thermostat monitors the ambient temperature and automatically turns the fan on when the set temperature is reached. Adjustment is made via a control knob, adjustable between 0 and +60 °C. Power supply is via the network cable (230 V), with the connection cable featuring grounding for safe use in IT environments. The vertical orientation of the fan unit ensures airflow is directed vertically through the rack, which is particularly advantageous for deep racks or cooling modules located in the middle of the rack.

Compatibility and Accessories

The fan unit is designed for mounting in 48,3 cm ( 19 inch ) racks. Slide rails are recommended for installation, especially when used in VERTIV Knürr® 6-way racks, where they are required. The unit is not intended for use in racks without appropriate mounting aids. Compatibility is limited to standard 48,3 cm ( 19 inch ) rack dimensions, with specified dimensions of W440/H44/D230 mm.

Installation and Mounting

Mounting is done using slide rails inserted into the rack. The fan unit is slid into the rails and secured. The connection cable is plugged into a grounded socket. The unit is pre-assembled, wired, and tested, so no additional assembly work is required. The included user manual provides instructions for correct installation and thermostat adjustment.

Operational Advantages

The thermostat-controlled fan function ensures targeted cooling that is only activated when needed, reducing energy consumption and minimizing operating noise. The robust construction from galvanized steel sheet and the powder-coated front trim panel ensure long service life and a clean visual appearance. The unit is designed for professional IT environments and complies with the Low Voltage Directive 73/23/EEC and the EMC Directive 89/366/EEC, as confirmed by the CE marking. The unit is delivered pre-assembled, wired, and tested, simplifying installation and enhancing operational safety.

Approvals and Safety

The fan unit carries the CE marking in accordance with the Low Voltage Directive 73/23/EEC and the EMC Directive 89/366/EEC. These approvals confirm compliance with European safety and electromagnetic compatibility requirements. The unit is intended for indoor use and meets requirements for IT infrastructures.

Scope of Delivery

The scope of delivery includes: 1 fan unit VERTIV Knürr® fan unit, packaged with user manual, and 1 connection cable with a length of 2 m, designed for connection to a grounded socket. The unit is pre-assembled, wired, and tested.

Material and Surface

The housing is made of galvanized steel sheet, providing high mechanical strength and corrosion resistance. The front trim panel is powder-coated in RAL 7035 light grey, ensuring a uniform, smooth surface and good fit within existing rack environments. The stainless steel grille ensures safe and open airflow.

Operating Temperature Range

The fan function is adjustable between 0 and +60 °C, allowing the unit to be flexibly adapted to different cooling requirements. The operating temperature of the device itself falls within the range typical for use in IT racks, with the fan function only activating when the set temperature is reached.

Dimensions and Weight

The fan unit has dimensions of W440 mm × H44 mm × D230 mm and weighs 3 kg. These dimensions correspond to the standard for 1 U components in 48,3 cm ( 19 inch ) racks. The unit is compact and fits into most standard rack configurations.
