Company Summary

Company Overviews

Subzero ensures a superior customer experience by applying unique product designs, quick turnaround
engineering, and in-house installation teams.

Founded in 2005 by Larry Mainers and Vince Lake, Subzero started out as a data center airflow consulting company utilizing CFD studies to provide layout and design recommendations. The next decade would see them develop and release numerous industry changing products that would define how data center containment could and would be done. With the addition of server cabinets, PDUs, cages, and hyper scale specialty offerings, Subzero has cemented itself as a go to partner in a growing industry.

Our Sales Engineers will be working closely with your Data Center Solutions Manager to ensure a successful and enjoyable experience. All products have been built to scale inside of SolidWorks, which allows for quick turnaround on mechanical drawings. A typical proposal and drawing set can be provided in as little as 24 hours, and never more than 72.

From its inception, Subzero’s offerings have always been about three things:

CUSTOMIZATION
Data centers are varied and dynamic, the solutions that go inside them should be too. Subzero’s entire line of products are all completely customizable allowing the ability to quickly design, ship, and install.

QUALITY
A culture of best-in-class has been a part of Subzero from the beginning. From the raw materials used, to the components sourced, this self-imposed standard ensures that a great design becomes an even greater product.

FIT AND FINISH
Flexibility and quality are important, but it needs to look good too. High precision machining combined with thoughtfulness in design guarantees a great looking product. Highly trained and experienced site service teams ensure each project is deployed to meet the quality standards above.

Thanks for taking the time to consider us, and we look forward to working with you.
