E‑Wrap™ Endothermic Wrap is a high‑performance fire‑protection wrap engineered to safeguard critical circuits and essential infrastructure, including circuits servicing fire pumps, signaling systems, elevators, alarms, process control equipment, Emergency Responder Communications Enhancement Systems (ERCES), and fuel‑oil piping. Designed for demanding environments, E‑Wrap provides reliable passive fire protection to help ensure operational continuity during fire events. When installed around Electrical Metallic Tubing (EMT), electrical conduits, cable trays, or piping systems, E‑Wrap activates under heat by releasing chemically bound water, creating a powerful cooling effect resisting flame and temperature rise. This endothermic reaction delivers up to 2 hours of fire protection, helping maintain the functionality of critical emergency circuits and life‑safety systems under severe fire conditions. Engineered for versatility, E‑Wrap offers dependable performance across commercial, industrial, and mission‑critical facilities, making it an ideal solution for protecting vital building systems that must remain operational during emergencies.
