MAXI-COOL - Mercury Range

The Maxi-Cool Mercury is a ventilated server cabinet designed for businesses that need quiet, clean, and reliable cooling for lighter server loads — without the cost or complexity of an active refrigeration system. Integrated fans draw a continuous stream of filtered air through the cabinet, keeping equipment cool and dust-free, and run from a standard 3-pin wall plug.
Mercury cabinets are IP54 rated, mounted on castors for easy portability, and available in a wide range of sizes and finishes. Like all Maxi-Cool products, they are designed and manufactured in the UK, fully customisable to your specification, and supplied with a 12-month parts-and-labour warranty.
Crucially, Maxi-Cool Mercury can grow with your business. If your server loads increase over time, the Gemini split system is retrofittable directly onto your existing Mercury cabinet — meaning you never need to replace the cabinet itself, upgrade the cooling. It’s a future-proof investment from day one.
Performance
The Mercury is designed for light to medium server loads where active cooling isn’t yet required, but reliable, filtered cooling is essential. It’s particularly well-suited to small offices, retail environments, edge computing locations, and any site where a simple, low-maintenance solution is preferred.
The Mercury uses filtered ventilation with very low power consumption — making it one of the most cost-effective and low-maintenance server cooling options available.

A Modular, Future-Proof Solution
One of Maxi-Cool Mercury’s most important features is its role within the wider Maxi-Cool ecosystem. It isn’t just a standalone product — it’s the first step in a modular cooling journey that can scale alongside your business.
Start with Mercury for light-load cooling. If your server demand increases and you need active server cooling, retrofit the Gemini split system directly onto your existing Mercury cabinet. No new cabinet needed — just an upgraded cooling unit. This approach minimises waste, protects your original investment, and means your cooling infrastructure can always keep pace with your IT growth.
This modular philosophy makes the Mercury particularly popular with growing businesses, edge computing deployments, and organisations that want a flexible infrastructure they can adapt over time rather than replace.
How the Mercury Works
The Mercury uses an integrated fan-based ventilation system to draw cool ambient air in through filtered vents at the front of the cabinet. Filtered air flows across the server equipment inside, absorbing heat, before being expelled from the rear or top of the cabinet.
The IP54-rated cabinet ensures that dust, debris, and moisture are kept out at all times — protecting your equipment and reducing maintenance requirements. The fans run quietly and continuously, maintaining a steady airflow.
Because the Maxi-Cool Mercury works best in environments where the surrounding room temperature is controlled and measurable. If ambient temperatures rise significantly or server loads exceed the ventilation system’s capacity, we can retrofit the active-cooling Gemini system without any structural changes.
