The Rittal TX Colocation Rack, type 5540.245, is a standardised server rack system for use in large data centres. It is an IT rack with a mounting height of 52 U, dimensioned at 600 mm width, 2450 mm height, and 1200 mm depth. The enclosure is made of steel sheet and designed for high mechanical load capacity, with a maximum load-bearing capacity of 15,000 N. The surface of the rack frame is dip-primed, the internal assembly is painted, while doors and roof are dip-primed and powder-coated. The base colour of the rack is RAL 7035, with doors and roof also in RAL 7035, while handles and hinges are painted in RAL 9005.

Applications
This rack is specifically designed for use in large data centres, where central IT infrastructure and optimised airflow are required. Integrated air baffle plates and a partition panel ensure targeted airflow, supporting cooling of installed IT components. The ventilated doors enable efficient thermal dissipation and are optimally matched to room climate control systems. The cable tray on the rear right side of the rack and cable entries in the roof plate across the full depth on both left and right sides facilitate structured cable routing.

Functions and Equipment in Detail
The front door is a ventilated steel sheet door, with an aluminium-steel sheet variant also available. The door is single-piece and offers a free area in the perforated sheet section of approximately 78 %. The rear door is also ventilated, double-piece, and made of steel sheet, with a comparable ventilation area. Both doors are fitted with 130° hinges, allowing for a wide opening angle. Access protection is ensured by a VX comfort handle with a numeric code lock on both front and rear sides. Mounting is carried out via mounting brackets, which are screwed to the frame structure at the top and bottom.

Technology Explained Simply
The frame structure is pre-assembled and consists of welded, 9-fold bent, closed hollow profiles, providing high torsional stiffness. The perforation follows a 25 mm grid, enabling flexible mounting of devices. Integrated blind rivet nuts M6 allow secure, IP-rated fastening of fittings. The horizontal profiles feature an integrated groove above the PU foam seal to protect it from mechanical damage. The profile rails are positioned in the 48,3 cm ( 19 inch ) plane at front and rear, enabling symmetrical device mounting.

Compatibility and Accessories
The rack is equipped with a baying set, enabling secure arrangement of multiple racks side by side. The delivery includes a partition panel on the left rack side, a 150 mm cable tray on the rear right side, 10 cage nuts with screws, earthing accessories (loose), profile rails (482.6 mm), and an air baffle plate. The door material thickness is 1.2 mm. The spacing between mounting levels in the delivered state is 745 mm, with a minimum distance between mounting levels of 115 mm and a maximum of 341 mm.

Mounting and Installation
Mounting is performed via the integrated mounting brackets, which are attached to the frame structure at the top and bottom. The designated mounting levels allow flexible adaptation to the respective device configuration. The doors are fitted with 130° hinges, enabling wide opening, although the actual opening angle may vary depending on the installation location. The floor construction is open, allowing flexible installation on various subfloors.

Operational Advantages
The rack offers an immediately operational configuration tailored to the requirements of large data centres. Integrated air baffle plates and the partition panel optimise airflow, improving cooling performance for installed IT components. Ventilated doors and structured cable routing via the cable tray and roof cable entries simplify maintenance and operation. The high load capacity of 15,000 N and the robust steel sheet construction ensure long service life and reliability in industrial use. From 01.09.2026, rear doors will be delivered with improved reinforcement elements and an optimised locking mechanism, increasing stability.

Scope of Delivery
The scope of delivery includes the rack frame with doors and roof plate, a ventilated steel sheet front door with 130° hinges, a double-piece ventilated steel sheet rear door with 130° hinges, a VX comfort handle with numeric code lock on front and rear, a roof plate with cable entries across the full rack depth on both left and right sides, a partition panel on the left rack side, a 150 mm cable tray on the rear right rack side, 10 cage nuts incl. screws, earthing accessories (loose), profile rails (482.6 mm), an air baffle plate, and a baying set (loose).
