**Q: What sizes does the DX-Series come in?**

A: 42U and 47U heights, 600 mm or 800 mm wide, and 1000, 1200 or 1400 mm deep. Other combinations can be quoted as a custom build.

**Q: What is the load rating?**

A: The DX-Series is rated for a 1500 kg static load. For higher rated loads, see the W-Series (2500 kg static).

**Q: Is the DX-Series frame welded?**

A: Yes. The DX-Series is built on a welded frame structure rather than a bolted kit, which is what gives it its rigidity in transit and under load. It is welded, coated and assembled in our own factory in Yambol, Bulgaria.

**Q: What door and access control options are available?**

A: An 80% mesh front door is standard, with solid or glass optional and a reversible hinge. Every DX-Series door has a 3-point latch as standard for security, and that latch takes the access control option you choose: the standard 1333 key, a combination lock, a profile cylinder, RFID access or a custom solution.

**Q: What side panel options are there?**

A: Side panels can be specified on both sides, on the left side only, on the right side only, or left off entirely. Panels are two-piece and removable, so a bayed cabinet only needs panels at the ends of the row.

**Q: Does the DX-Series have earthing points?**

A: Yes. Earthing points are fitted as standard so the frame, doors and removable panels can be bonded to your earthing scheme.

**Q: Can DX-Series cabinets be joined in rows?**

A: Yes. The DX-Series is bayable and joins side-by-side in rows for cold-aisle/hot-aisle deployments. It is single-bay; multi-bay secure colocation compartments are the W-Series line.

**Q: Does it integrate cooling and PDUs?**

A: Yes. The DX-Series is designed to integrate rack-door cooling units and metered or switched PDUs, specified with the cabinet and fitted at the factory before it ships.

**Q: What is the lead time?**

A: Standard configurations are built on a 2–4 week European lead time. Cabinets are welded and assembled in-house in Yambol, Bulgaria, with no overseas sourcing cycle.

**Q: What standards is the DX-Series built to?**

A: The DX-Series is built to EIA-310-D, the standard that defines 19-inch rack rail geometry and hole spacing, and to EN IEC 61587-1, the European standard covering mechanical structures for electronic equipment. Test and compliance documentation is available on request.

**Q: Is the DX-Series compatible with standard 19-inch equipment?**

A: Yes. Because the mounting rails follow EIA-310-D hole spacing, any standard 19-inch rack-mount server, switch or rail kit fits. The four rails adjust in 25 mm increments so mounting depth can be set to the equipment rather than the other way round.

**Q: How is W-Series different from the DX-Series?**

A: Both lines are built on welded frames. The W-Series goes further on load (up to 2500 kg static), covers a wider 39–51U height range and offers secure multi-bay compartments for colocation. The DX-Series is the standard, bayable 42U/47U rack. Choose the W-Series when you need higher load, a non-standard height or secure compartments in one cabinet.

**Q: What load can the W-Series take?**

A: Up to 2500 kg static and 1800 kg dynamic, thanks to its welded rigid frame.

**Q: What sizes and bay layouts are available?**

A: Six standard sizes, all 800 × 1 200 mm, with the bay count paired to the height: 39U/3-bay, 40U/2-bay, 42U/1-bay, 48U/4-bay, 50U/2-bay and 51U/1-bay. Other heights, dimensions and compartment splits are available as welded bespoke builds.

**Q: How does colocation security and metering work?**

A: Each bay is an independently locked compartment. Access control is specified per compartment (1333 key, combination lock, profile cylinder, RFID or a custom solution), and metered PDUs provide per-tenant energy metering for billing.

**Q: Has the colocation cabinet been shown publicly?**

A: Yes. A 48U colocation cabinet with 4 × 12U secure compartments was exhibited at Data Centre World London 2026.

**Q: What standard is it built to?**

A: The W-Series is designed and built to IEC 61587-1. This is a build reference; formal certification is available on request.

## Integrated access, cooling and power

URL: https://www.wenvex.com/partners

Wenvex integrates three subsystems into its data-center cabinets: access and security (electronic locks, swing handles and RFID entry), cooling and thermal (rack-door cooling units), and power distribution (metered and switched PDUs). Each is specified on the order, sourced from established European vendors and fitted at the factory in Yambol, Bulgaria, so a DX-Series cabinet arrives as a complete, working system rather than a rack that still needs integrating on site.

**Q: Which vendors do you integrate?**

A: We specify hardware from established European access, cooling and power vendors and match it to the cabinet on a per-project basis. We name specific vendors on request, tell our engineering team what you already run and we will confirm compatibility for your build.

**Q: Can I order a cabinet with the PDU, cooling or locks already fitted?**

A: Yes. Specify the access, cooling and power you need on your RFQ and we integrate and fit them before the cabinet ships, so it arrives configured and commissioned-ready, not as separate parts to assemble on site.

**Q: What access control options are supported?**

A: Electronic locks, swing handles and RFID/badge access, all matched to the DX-Series 3-point latch. Electronic locking supports audit-trail access logs, and colocation builds can be locked per compartment.

**Q: Does the DX-Series support rack-door cooling?**

A: Yes. Rack-door cooling units are specified against the DX-Series depth and door options and are the standard answer for high-density and HPC loads where room-level cooling is not enough.

**Q: Can PDUs be metered per tenant?**

A: Yes. Metered and switched PDUs support per-outlet and per-PDU energy reporting plus remote power switching, which is what colocation operators need for per-tenant billing.

**Q: Can you integrate hardware we already standardise on?**

A: In most cases yes. Send us the part numbers with your RFQ and our engineering team will confirm fit against the cabinet's door, rail and cable-channel geometry before quoting.

## Guides

### How to specify a data-center cabinet

URL: https://www.wenvex.com/resources/guides/how-to-specify-a-data-center-cabinet · Last reviewed: 2026-07-04

To specify a data-center cabinet, define eight things: rack-unit height, width, depth, load rating, door and airflow type, mounting-rail depth, access and security, and power and cooling. Get those right and the rest, colour, baying and cable management, follows.

#### 1. Rack-unit height (U)

Height is measured in rack units (U), where 1U = 44.45 mm. Standard data-center racks are 42U or 47U; taller 48–51U frames exist for high-capacity or colocation use. Choose the height by the equipment you need to mount plus room for PDUs, cable management and airflow.

#### 2. Width

Standard widths are 600 mm and 800 mm. The 19-inch mounting space is the same; the extra 200 mm on an 800 mm cabinet is side space for vertical cable management and PDUs. Choose 800 mm for dense cabling and per-tenant power, 600 mm to maximise floor efficiency.

#### 3. Depth

Depth must fit your deepest server plus cable-management and PDU clearance at the rear. Common depths are 1000, 1200 and 1400 mm. Depth-adjustable mounting rails let you position equipment planes precisely inside that envelope.
- 1000 mm: network and shallow equipment
- 1200 mm: general server deployments (most common)
- 1400 mm: deep servers, rear PDUs and heavy cabling

#### 4. Load rating

Static load is the weight a cabinet holds standing still; dynamic load is what it can carry while being moved or shipped loaded. Standard racks are typically designed for around 1500 kg static; welded high-load cabinets reach 2500 kg static / 1800 kg dynamic. Match the rating to fully-populated equipment weight with margin.

#### 5. Doors & airflow

An 80% perforated (mesh) door is the default for air-cooled equipment because it maximises front-to-back airflow. Solid or glass doors suit low-airflow or display use. For high-density loads, rack-door cooling handles heat at the cabinet. A reversible hinge lets you set door swing to suit the aisle.

#### 6. Mounting rails

Four 19-inch EIA rails carry the equipment. Depth-adjustable rails, ideally in fine (25 mm) increments, let you set the mounting plane for deep servers, rear PDUs and cable arms without compromise.

#### 7. Access & security

A 3-point latch is standard. For controlled or multi-tenant environments, add electronic locks or RFID access with audit trails, and per-compartment locking for colocation bays.

#### 8. Power & cooling

Specify PDUs by phase, sockets and intelligence, metered or switched PDUs enable per-tenant billing and remote control. For dense heat, integrate rack-door cooling. Fitting power and cooling with the cabinet at the factory avoids on-site integration work.

#### Specification checklist

**Capture these before you request a quote**

| Property | Value |
| --- | --- |
| Height | e.g. 47U |
| Width | 600 or 800 mm |
| Depth | 1000 / 1200 / 1400 mm |
| Load | fully-populated weight + margin |
| Doors | mesh / solid / glass; hinge side |
| Access | 3-point / electronic / RFID |
| Power | PDU phase, sockets, metered/switched |
| Cooling | passive airflow / rack-door cooling |
| Colour & baying | RAL; standalone or bayed rows |

**Q: What is the most common data-center rack size?**

A: A 42U or 47U rack, 800 mm wide and 1200 mm deep, is the most common general-purpose data-center cabinet.

**Q: How do I know what depth I need?**

A: Take your deepest device, add rear clearance for cabling and PDUs (typically 150–250 mm), and choose the next standard depth up: 1000, 1200 or 1400 mm.

**Q: Static vs dynamic load: which matters?**

A: Both. Static load governs the fully-populated cabinet in place; dynamic load matters if it will be shipped or moved while loaded.

### Rack depth: 1000 vs 1200 vs 1400 mm

URL: https://www.wenvex.com/resources/guides/rack-depth-1000-1200-1400 · Last reviewed: 2026-07-04

Choose rack depth by your deepest device plus rear clearance for cabling and PDUs. 1000 mm suits network and shallow gear, 1200 mm is the general-purpose default, and 1400 mm is for deep servers, rear-mounted PDUs and heavy cabling.

#### What depth actually has to fit

A cabinet's external depth has to accommodate the front door, the equipment itself, rear cabling and vertical PDUs, and the rear door. Depth-adjustable mounting rails let you slide the equipment plane forward or back within that envelope, but the external depth sets the ceiling.

#### Choosing by use case

**Depth by deployment**

| Property | Value |
| --- | --- |
| 1000 mm | Network switches, patch panels, shallow appliances |
| 1200 mm | General servers: the most common choice |
| 1400 mm | Deep GPU/HPC servers, rear PDUs, dense cabling |
If you are unsure, 1200 mm covers the majority of standard server deployments. Move to 1400 mm when you run deep chassis, need generous rear cable management, or mount PDUs and cooling at the back.

**Q: Is 1200 mm deep enough for most servers?**

A: Yes. A 1200 mm cabinet handles the majority of standard rack servers with room for rear cabling and PDUs. Very deep GPU/HPC chassis may need 1400 mm.

**Q: Do the mounting rails move within the depth?**

A: On the DX-Series the four rails are depth-adjustable in 25 mm increments, so you can position the mounting plane precisely regardless of the external depth.

### Mesh vs solid vs glass rack doors

URL: https://www.wenvex.com/resources/guides/mesh-vs-solid-vs-glass-doors · Last reviewed: 2026-07-04

For air-cooled equipment, use an 80% perforated (mesh) door front and rear. It maximises front-to-back airflow. Use solid doors only where airflow is handled another way (e.g. rack-door cooling), and glass doors for display or low-heat use.

#### Why perforation matters

Servers pull cool air in the front and exhaust hot air at the rear. A door that blocks that path traps heat and raises inlet temperatures. An 80% open-area mesh door is the standard because it lets equipment breathe while still providing security and structure.

#### When to use each

**Door type by need**

| Property | Value |
| --- | --- |
| Mesh (80%) | Default for air-cooled servers; best airflow |
| Solid | With rack-door cooling, or non-airflow enclosures |
| Glass | Display, reception or low-heat equipment |
High-density cabinets that exceed what perforation can handle should pair a solid or cooling door with rack-door cooling, which rejects heat at the cabinet rather than relying on room airflow.

**Q: What perforation percentage is best for airflow?**

A: Around 80% open area is the industry standard for air-cooled equipment, enough airflow to avoid restricting server cooling.

**Q: When should I choose a solid door?**

A: When airflow is handled another way, for example a sealed enclosure or a rack-door cooling unit, or for equipment that doesn't need front-to-back airflow.

---

### Rack-door cooling explained

URL: https://www.wenvex.com/resources/guides/rack-door-cooling · Last reviewed: 2026-07-04

Rack-door cooling replaces a passive rear door with a cooling unit that removes heat as air leaves the cabinet, so hot exhaust is neutralised at the source. It is used for high-density and HPC racks whose heat load exceeds what perforated doors and room cooling can handle.

#### How it works

A rack-door cooling unit mounts where the rear door would be. As server exhaust passes through it, a chilled coil or refrigerant loop absorbs the heat, so the air entering the room is close to room temperature. This keeps hot aisles cooler and lets you run higher power per cabinet.

#### When to use it

- High-density racks (high kW per cabinet) beyond air-cooling limits
- GPU / HPC deployments with concentrated heat
- Rooms without capacity for more raised-floor or CRAC cooling
- Retrofits where per-rack cooling is easier than room upgrades
Wenvex cabinets are designed to integrate rack-door cooling units, specified against the cabinet's depth and door options and fitted before delivery.

**Q: What is a rear-door heat exchanger?**

A: It's a rack-door cooling unit fitted in place of the rear door that removes heat from server exhaust as it leaves the cabinet, reducing the load on room cooling.

**Q: When do I need rack-door cooling instead of perforated doors?**

A: When cabinet heat density exceeds what an 80% mesh door and room airflow can handle, typically high-density or HPC racks.

### Metered vs switched PDUs

URL: https://www.wenvex.com/resources/guides/metered-vs-switched-pdus · Last reviewed: 2026-07-04

A metered PDU measures power draw (for monitoring and per-tenant billing); a switched PDU adds remote on/off control of individual outlets. Choose metered when you need visibility and billing, and switched when you also need remote power cycling and outlet control.

#### The four PDU classes

**From basic to intelligent**

| Property | Value |
| --- | --- |
| Basic | Power strip; no measurement or control |
| Metered | Measures current/energy; enables billing |
| Switched | Remote on/off per outlet |
| Metered + switched | Measurement plus per-outlet control |

#### Choosing for colocation

Colocation providers typically need metered PDUs so each tenant's energy can be measured and billed accurately, often per compartment. Switched capability adds remote reboot and outlet control, useful for managed services and unattended sites.
Wenvex cabinets are designed to integrate metered and switched PDUs, fitted in the vertical cable channel and specified with the cabinet.

**Q: Do I need a switched PDU for colocation?**

A: Not necessarily. Metered PDUs are usually enough for per-tenant billing; add switched capability if you need remote outlet control or power cycling.

**Q: Can PDUs meter power per tenant?**

A: Yes. Metered PDUs report energy per PDU or outlet, which supports per-tenant colocation billing.
