Details
Use Case: Server Room Validation
Used to simulate the thermal output of live server racks, the X20F enables engineers to validate HVAC and airflow performance during data centre commissioning and pre-deployment testing.
Standard 20kW Unit
The Fortress X20F is designed specifically for data centre environments. It replicates server heat load while producing a low temperature rise, ensuring accurate HVAC stress testing without overheating the room. Units are designed for vertical, rack-adjacent installation and can be stacked up to three-high for scalable deployments.
We’re here to answer all your questions
Got questions? We’ve got answers! Below are some of the most common inquiries about our products and services. If you don’t find what you’re looking for, feel free to reach out to our team—we’re happy to help!
Low delta T airflow allows engineers to test HVAC system effectiveness without distorting room temperature, delivering realistic thermal validation results.
Units should undergo a function test (airflow and power) every 6 months, with a visual inspection recommended annually.
Yes – all Fortress air-cooled load banks are MURC (Multi Unit Remote Controller) compatible and can be controlled in groups of up to 200 units.
5m, 10m, and 15m cable/connector sets are available as standard. Custom lengths can be requested.
Very little – we recommend downloading the product datasheet and getting in touch with the number of X20F units required.
