DARMET™
Darchem’s DARMET™ is a fully engineered, all-metallic insulation system designed to control heat loss and manage temperature gradients on primary circuit vessels, equipment, and pipework.
Installed in over 180 nuclear power plants worldwide, DARMET™ is constructed from austenitic stainless steel, offering exceptional thermal performance and operational reliability.
Key Advantages Over Conventional Fibrous Insulation:
- Removable & Replaceable for ease of maintenance
- Corrosion Resistant for long-term durability
- Non-Radioactive When Irradiated
- No Health Risks during handling or operation
- Drainable Design for improved system integrity
DARMET™ helps reduce heat loss, lower containment air temperatures, and minimize equipment issues—making it a superior choice for high-integrity nuclear insulation.
