Thermal Insulation
Services focused on energy efficiency, extending equipment service life, and reducing operational risks.
Removable and Reusable Thermal Insulation
Our thermal jackets ensure energy efficiency, high quality and safety. ISO 9001:2015 certified and recognized by DNV to develop removable and reusable jackets for industrial equipment.
Passive Fire Protection
Removable fire jackets protect equipment during emergencies by mantaining safe temperatures. They withstand pressures up to 23.5 PSI (1,62 bar), allow ventilation and inspection, and hold Lloyd's Register Type Approval Certification, ensuring high performance and reliability.
Thermal Insulation for Engines
Thermal insulation for engines prevents burns, reduces ambient heat, protects sensors, and prevents failures caused by overheating. Our jackets are non-combustible, produce no smoke emissions, and enhance the safety and durability of your systems.
