Fog Hashing

The company's product catalog spans four hardware lines. The **C Series** addresses home and small-scale mining with compact immersion cooling tanks; the **B Series** delivers modular immersion systems for mid-to-large mine sites; the **H Series** provides modular hydro cooling containers; and the **M Series**, developed in collaboration with WhatsMiner, is a native immersion product targeting fleet-wide migration from air-cooled ASICs. The flagship containerized unit, the **BC40 Elite**, launched at Mining Disrupt 2024 in Miami, provides 1 MW of cooling capacity and accommodates up to 200 S21 miners per container. Fog Hashing reports 400 MW of field-proven capacity across its deployments.

CEO Dr. Paul Li has represented the company at three consecutive Consumer Electronics Show appearances in Las Vegas: the 2022 CES debut of the C1 home immersion unit, the 2023 launch of the C2 and a large-scale mining stack, and the 2024 presentation of the M Series alongside WhatsMiner. Documented pilot deployments span the United States, South Korea, and Serbia. The company also participated in the Bitcoin Energy Summit 2024, where it positioned its infrastructure across both bitcoin mining and AI compute workloads.

At Mining Disrupt 2023, Fog Hashing launched a liquid cooling ecosystem initiative and signed strategic cooperation agreements with Osprey, Iceriver, Repairbit, Apexto, and BOMBAX MINER. In 2024, the company announced delivery of what it described as the world's first large-scale container-based H100 immersion cooling project, a milestone in its push into GPU-dense AI deployments. Dr. Paul Li authored the foreword to *Bitcoin Mining Heat Reuse*, a book co-published with Braiins and written by Tyler Stevens on thermal reuse applications in mining operations.

Fog Hashing maintains its Singapore headquarters at Duo Tower (3 Fraser Street), a U.S. office at 440 N Wolfe Road in Sunnyvale, and an R&D laboratory in Xi'an, China, with approximately 40 employees. Its FogCare post-deployment program covers one to ten years of service, backed by a three-tier spare parts inventory and annual coolant chemical analysis. The company formulates its own Group-4 synthetic oil immersion fluid, rated for over 10 years of operational life, with sample-testing available as a premium service for key customers.

Fog Hashing was profiled in a May 2025 BIS Research analysis of the Asia-Pacific data center liquid cooling market, and the company is expanding container-scale deployments for both bitcoin mining operators and AI computing clients globally.
