The Heizka Server Rack Cabinet – D Series is a reinforced 45U floor-standing enclosure engineered for data centres and high-density server rooms that need serious static load capacity beyond Heizka’s standard cabinet range. Built on a disassembled, flat-packing structure for easier transport, the D Series steps up frame, rail, and base thickness so a fully populated 45U rack – switches, patch panels, UPS units and rack-mount servers – can be carried safely.
Every rack position is engraved and painted on all four rail bars from 1U to 45U in a contrasting colour, so equipment goes in exactly where it was planned. A dedicated grounding point on the frame, sealed cable-access ports, and a spring-locked front and rear door (tempered glass or perforated steel) round out a cabinet built for continuous data-centre duty. Every unit is manufactured to ANSI/EIA RS-310-D and IEC 297-2, ETSI, DIN 41494 Part 1/7, and GB/T 3047.2-92 standards, and is backed by Heizka’s multi-year warranty for long-term field performance.

Note: all D Series item numbers share the pattern HER45…XYD – the digits after 45 identify the cabinet’s width/depth combination, X is the front door option (S = perforated steel, G = tempered glass), Y is the rear door option (1 = single door, 2 = wing/double door), and the trailing D marks the heavy-duty D Series. Contact Heizka to confirm the exact width × depth for a specific code.

Frequently Asked Questions
The D Series is a fixed 45U enclosure engineered for higher static loading – up to 1800 kg versus 800–1000 kg on the standard range – with a dedicated frame grounding point and a fixed, wheel-free base. Choose it for dense, fully loaded data-centre racks; choose the standard Server Rack Cabinet when you need a choice of U sizes (27U–47U) or mobility via adjustable feet and castors.
Static loading is rated up to 1800 kg, with a dynamic (in-motion) rating of 800 kg, supported by a 2.0 mm SPCC cold-rolled steel frame and rail with a mechanical strength greater than 20 N/mm².
Both options share the same 0.72 m² opening area (a 75% open-area ratio) for strong passive airflow. Perforated steel is the common choice where maximum ventilation for heat-generating servers matters most; tempered glass suits network and AV cabinets in visible areas where appearance and dust control are a priority.
No. The D Series ships with a fixed base – no wheels and no standing legs – for maximum stability under heavy static loads. A dedicated grounding point bonds the entire cabinet frame for safe, code-compliant electrical continuity.
Every rail bar is engraved and painted with rack-unit numbers from 1U to 45U in a contrasting colour, so technicians can identify the correct mounting position at a glance without measuring or guesswork.
Packaging & Delivery
Like the rest of Heizka’s rack cabinet range, the Server Rack Cabinet – D Series ships as a disassembled, flat-packed kit – frame, doors, side panels, rail bars and mounting hardware are packed together and assembled on site. Flat packing reduces freight volume, protects the powder-coated finish in transit, and lets the cabinet pass through standard doorways and service lifts before assembly.
Every Heizka 45U Server Rack Cabinet – D Series ships flat-packed and ready for fast on-site assembly.
