How We Work

HeatLoad: past, present and future.

HeatLoad was founded in 2002 (as Mafi Mushkila Ltd) on the belief that there was a better way of carrying out data centre heat-load testing. Driven by this conviction, we are now a leading UK provider of these services. We believe that our expertise, equipment and efficiency set us apart. This is why.

Our expertise

Our expertise is based on extensive experience, not least that of our Director, David Wolfenden. He established Mafi Mushkila Ltd utilising his extensive knowledge of building data centres and project managing their design and development, which are the foundations of our company.

Fast forward and today, with offices, warehousing and partners in the UK, France and Spain, and a team of certified professionals, we are a trusted supplier of data centre heat-load testing equipment to clients around the world.

Our efficiency

We know how stressful data centre delivery can be – we have been providing heat-load testing services for a long time. There is always pressure on schedules. This is why we make it easy for you to get the equipment you need as quickly as possible.

This efficiency matters. When you contact us, you talk directly to the people who can organise and ship the heat-load testing equipment that meets the specifications of your data centre build.

Our equipment

We offer a wide range of data centre heat-load testing equipment. This means that, whatever the project, we have the solutions. And we hold a large stock of these heaters, emulators, power distribution units and monitoring systems. This means that, whatever the scale of your project, we have the resources.

Innovation is intrinsic to who we are and what we do. The Immulator™ – a first-of-its-kind immersion-cooling server emulator for data centres and an example of the innovation that is intrinsic to who we are and what we do.
