Maxi-Cool Top Mounted System


5kw top mount server cooling cabinet

Designed for cooling all cabinets, the top mount Maxi-Cool Halo cooling system gives users a powerful system providing up to 5kW of cooling. Cooling efficiency and minimized power usage are assured by cooling only the cabinet, not the whole room, and every item of equipment receives cooling air at exactly the right temperature. The system can be mounted in cabinets from 18u in height upwards, and as with all products in the Maxi-Cool range, it has a portable design.

Much like enterprise data centres, today’s smaller server room environments are dealing with significant increases in server rack density. Maxi-Cool HALO TM5 was created to provide a portable 5kW rack-mounted server cooling system that was more effective than conventional environmental cooling techniques and did not require any externally mounted condensers. The HALO TM5 is an innovative server cabinet with an integrated and self-contained cooler, which can be bespoke and manufactured in accordance with each specific business requirement and corporate identity.

The Maxi-Cool HALO TM5 is ideal for offices with limited space, as units can be adapted from our UK-based manufacturer to the bespoke needs of individual servers in a modular fashion, providing more efficient cooling and sustainable energy use. Multiple units can be banked together in a row creating flexible cooling solutions as your business needs and data demands grow. The units are cooled independently using ambient air within the office and the unit itself emits less than 65db. 


If servers and other networking equipment are not kept cool, they’re prone to failure and a shortened lifespan. Damage caused by heat is not always immediately evident – signs of heat damage include node crashes and hardware failures that can happen over a period of weeks or even months, leading to chronic downtime.

Maxi-Cool HALO TM5 offers 5 kW of server cooling power, directly into the racks, but sits on top of the cabinet to maximise usable space. It reduces power consumption and running costs compared to air conditioning, and alleviates the need for a dedicated server room, meaning the rack cooling cabinet can sit in an everyday office environment.

The Maxi-Cool HALO TM5  power consumption is less than 7.0 Amps at full working load.  A cost-effective and sustainable alternative to server room air conditioning.

How It Works

Our MAXI-COOL server cabinet cooling systems are engineered to ensure all the equipment in the enclosure is precisely cooled and hotspots are eliminated. Hot air from the servers is blown into the rear of the cabinet and drawn into the Maxi-Cool unit to be cooled and returned to the front of the servers.

The waste heat extracted from the cabinet is expelled as warm air from the top of the MAXI-COOL® unit. The server cabinet doors are kept closed and Maxi-Cool activates when the temperature of the server intakes rise above 21 degrees Centigrade.

The cabinet is dust-free as the doors are closed and it does not need water feeds or drains. The temperature inside the cabinet is displayed on a monitor on the front of the cabinet and the system runs off a standard 13 Amp wall plug.

Key Benefits

MAXI-COOL is a patented design and engineered and manufactured in the UK.
MAXI-COOL® technology eliminates hot-spots and keeps servers working faster with greater reliability.
MAXI-COOL® systems are acoustically insulated to minimise the noise from the servers. The unit itself emits less than 65db.
Quick Installation
All our MAXI-COOL® units are supplied ready for use and only take a couple of hours to install on-site.
Low Running Costs
Lower power consumption than conventional server-cooling, MAXI-COOL® reduces both your carbon footprint and your running costs.


MAXI-COOL® takes the form of a neat cabinet with an array of design options, it is quiet to run with no need for air-conditioning, making it an ideal solution for offices or listed buildings without dedicated server rooms.
MAXI-COOL® will work in your space if there is airflow. External cooling is not required.
MAXI-COOL® server cooling solutions are sold with 12 months parts and labour warranty. Maintenance contracts are available after the warranty period expires. Instructions for keeping the air filters clean are included.
