Square Robot, Inc., a global leader in robotic tank inspections, has developed its newest high temperature inspection robot, the SR-3HT, which has formally received NEC/CEC Class I Division 2 (C1D2) certification. The SR-3HT is now commercially available and capable of inspecting aboveground storage tanks where product storage temperatures range from -10°C to 55°C (14°F to 131°F).

The C1D2 certification was issued by FM Approvals, a third-party Nationally Recognised Test Laboratory, confirming the system is safe for use in hazardous locations. This certification and the expanded capabilities of the SR-3HT provides a solution for tank owners requiring onstream robotic tank inspections for tanks with products stored at elevated temperatures that sit outside Square Robot’s previous operating range of 0°C to 40°C (32°F to 104°F).

David Lamont, Chief Executive Officer, commented on the development: “Our Engineering team developed the SR-3HT in response to significant client demand in both the US and international markets. We frequently encounter higher temperatures due to both elevated process temperatures and high ambient temperatures, especially in the hotter regions of the world, such as the Middle East. The SR-3HT employs both active and passive cooling technology, greatly expanding our operating envelope. A great job done (again!) by our Engineers delivering world leading technology in record time.”

The SR-3HT represents the seventh certified model variant in Square Robot’s growing portfolio of robotic excellence. Beginning with the C1D2 SR-1 inspection robot, followed by the SR-3 robot and the Side Launcher system—which achieved C1D1 certification earlier this year—Square Robot continues to expand its robotic fleet capabilities.

The launch of the SR-3HT addresses a significant market need for inspection solutions in high-temperature environments, particularly benefiting operators in regions with extreme ambient conditions or elevated process temperatures.
