The Cold Pad C-HAWK is a programmable universal process controller purpose-built for structural adhesive bonding in harsh and hazardous industrial environments. Cold Pad, based in Paris, France, developed the C-HAWK to bring repeatable, controlled bonding processes into ATEX Zone 1 classified areas — where traditional welding or drilling is either unsafe or requires costly production shutdowns. The system sequences and monitors every phase of the bonded fastening cycle, from ambient condition verification through surface preparation, adhesive mixing and application, to final polymerization and curing.

How does the C-HAWK support live-production structural work?

Conventional structural modifications in oil and gas, nuclear, or chemical facilities typically require hot work permits, zone declassification, or complete process shutdown. The C-HAWK, combined with compatible cold cutting and ATEX surface preparation tools, enables structural bonding while production continues. The controller enforces the prescribed process parameters at each step — verifying that ambient humidity and temperature are within the adhesive manufacturer's specified window, confirming surface roughness after preparation, controlling mix ratio and application time, and monitoring cure progression — so each bonded joint meets the design specification regardless of the surrounding environment.

What makes the C-HAWK suited for hazardous area operation?

The C-HAWK is engineered for ATEX Zone 1 (gas/vapor) compatibility, meaning it can operate in areas where an explosive atmosphere is likely to occur during normal operation. The self-supporting design reduces the physical load on operators by eliminating the intense vibration and reaction forces associated with mechanical fastening tools — an important ergonomic consideration when working in confined spaces wearing full PPE. Typical deployment scenarios include structural reinforcement on offshore platforms, pipe support modifications in live chemical plants, and anchor installations in wind turbine foundations where grout curing must be precisely controlled.
