As an experienced innovator with over 60 patents and more than two million liquid cooling units deployed, CoolIT Systems is the top liquid cooling choice for HPC, Cloud and Enterprise markets worldwide.


CoolIT Systems’ Rack DCLC platform is a modular, rack-based and advanced liquid cooling solution which allows dramatic increases in rack densities, component performance and energy efficiencies. The technology can be deployed with any server and in any rack, making it a truly flexible solution that creates an edge in today’s highly competitive marketplace.

CoolIT’s Closed-Loop DCLC products are cooling systems that exist entirely within the desktop or server. A variety of efficient coldplate assemblies are installed on heat-producing components and hot air is then rejected through slim, quiet radiators. The sealed liquid loops ship pre-filled with coolant and installation is comparable to that of a standard heat sink. Closed-Loop DCLC solutions are available in both standard and custom rack-mount configurations.


Founded in 2001, CoolIT’s dedication to the invention and design of state-of-the-art liquid cooling technology has led to a portfolio of over 60 patents. The company’s reputation has always been synonymous with industry leading solutions.

Through proud collaboration with industry leaders like Apple, Dell EMC, HPE, Intel, AMD, NVIDIA, Supermicro and others, CoolIT Systems liquid cooling technology has become a staple in today’s high performance desktop computer and is destined to become the mainstream cooling solution in the world of data centers.

The persistent pursuit of high quality design, collaborative engineering, manufacturing and serviceability connects customers with design possibilities and exceptional performance results that only CoolIT’s Direct Contact Liquid Cooling can provide.

CoolIT Systems (CoolIT) was founded in 2001. The company has headquarters in both Calgary, Canada and Connecticut, USA, three manufacturing warehouses in Canada and China and sales teams located around the globe. CoolIT’s first products delivered superior performance for high-end workstations and gaming computers. Today, the company’s Direct Contact Liquid Cooling technology has evolved to support large scale data center installations.

In May 2016, STULZ and CoolIT created a unique partnership which provides customers with the world’s first Chip-to-Atmosphere solution. Chip-to-Atmosphere cooling solutions allow customers to capture dense heat loads at the source (inside the servers) and efficiently move it to the outside atmosphere. STULZ is world-renowned for its precision cooling products which are combined with CoolIT’s industry leading Rack DCLC technology. The result is ultra-efficient total thermal solutions that support any OEM server at even the highest density configurations – all through one unified vendor.


With a unique mission to “Make fast computers faster. Hot computers cooler. Environmental footprints smaller.,” today, CoolIT holds the ISO9001 certification, has a portfolio of over 60 patents, has sold over two million liquid cooling units worldwide and is the top choice for OEMs and System Integrators.
