About BITSINK

Engineering critical infrastructure for AI-scale compute

We design and manufacture the cooling and electrical systems that keep AI-scale data centers running — from first thermal model to 24/7 field support.

Our Story

Pioneered in dry coolers, built for the harshest sites on earth

BITSINK started by solving a problem the industry hadn't fully cracked: rejecting extreme heat loads outdoors, reliably, in the harshest climates on earth. Our dry coolers — spanning 60 kW to 2,160 kW of heat rejection capacity — became the backbone of GPU and ASIC compute sites deployed across more than 220 MW of installed capacity worldwide.

That same engineering discipline carried into two more product lines: immersion liquid cooling systems built to perform in hot, dry, and sandy climates where conventional cooling struggles, and a UL-certified panel shop producing UL508A and UL891 listed industrial switchgear. Three product families, one integrated approach to keeping compute cool and powered.

Manufacturing & Quality

Built and tested in our own facilities

Every dry cooler, immersion system, and switchgear lineup ships from our own UL-certified manufacturing facility in Chesnee, South Carolina — not a third-party contract manufacturer.

Every switchgear lineup is powered up and function-tested on our factory floor before shipment, with customer witness testing available on request.
All liquid cooling loops — CDUs, manifolds, and heat exchangers — are helium leak-checked to detect leaks below 1×10⁻⁷ atm·cc/s before crating.
Thermal chamber and vibration testing on new product introductions simulates shipping and multi-year operating conditions before a SKU reaches "Available Now" status.
Careers

Build the infrastructure behind AI

We're a team of thermal engineers, power electrical engineers, and manufacturing specialists solving problems that didn't exist five years ago. If you want to work on hardware that ships and gets deployed — not just simulated — we'd like to talk.
