Description
Product Overview
RAYCHEM EMDR‑10 is an intelligent energy‑saving control unit for nVent IceStop self‑regulating roof and gutter de‑icing heating cables (GM‑2X/T series)nVent. Instead of continuous heating, it triggers heating cable power supply only when ambient low temperature and gutter moisture are simultaneously detected, delivering substantial energy savings. It includes built‑in ambient temperature sensor and moisture sensor, potential‑free alarm contact for fault notification, DIN‑rail cabinet installation, widely deployed on commercial building roof, gutter and down‑pipe anti‑ice‑dam applications.
Series
IceStop series is nVent Raychem dedicated roof‑gutter snow‑melting & de‑icing solution, including self‑regulating heating cables, EMDR‑10 controller, installation accessories. The whole system is designed to eliminate ice‑dam and icicle hazards for building roofs.
Product Features
‑ Dual‑condition logic: heating output activates only when cold temperature AND moisture are detected, saves up to 80% energy vs constant‑on control‑ Equipped with ambient temperature sensor and gutter moisture sensor for field condition detection瑞侃Ray…‑ Adjustable frost protection threshold:‑3℃ ~ +6℃, configurable moisture sensitivity setting‑ Potential‑free SPDT alarm relay, reports sensor failure or unit fault to BMS or local alarm indicator‑ DIN‑rail mounting design for standard electrical cabinet installation‑ LED status indicators for power, heating output and fault diagnosis‑ 4W low standby power consumption, maintenance‑free long‑term operation‑ Compliant with European safety standard, IP20 indoor cabinet‑use protection grade
