DEVIpipeguard 25 LZSH Self-Limiting Heating Cable 250 m Drum

Self-limiting heating cable delivering 25 W/m at 10°C for reliable frost protection and temperature maintenance. Its low smoke zero halogen (LZSH) outer jacket makes it ideal for safety-critical installations in public buildings, tunnels, and industrial plants where fire safety is paramount.

Advantages

Self-regulating output automatically adjusts to ambient temperature, preventing overheating and saving energy. The halogen-free jacket emits very low smoke and no corrosive gases in the event of fire, protecting people and equipment. Cut-to-length capability on site allows precise fitting without waste. Robust tinned copper braid provides mechanical protection and enables effective grounding. Fluoropolymer insulation ensures long-term dielectric strength and resistance to moisture and chemicals. Suitable for installation on pipes, valves, tanks, and gutters, with a minimum bending radius of just 25 mm even at -20°C.

Suitable for

• Frost protection of water pipes, fire suppression lines, and sprinkler systems
• Temperature maintenance of hot water lines, grease lines, and process piping
• Roof and gutter de-icing in residential, commercial, and industrial buildings
• Protection of valves, flanges, and tanks in harsh environments
• Installations requiring halogen-free materials, such as tunnels, subways, and data centers

Recommendations

For maximum safety and performance, always terminate the cable with DEVI-approved connection kits and controls. Use a dedicated thermostat or controller to optimize energy consumption. Ensure proper electrical protection with a 30 mA RCD. Plan the cable layout to avoid overlapping, except where permitted by manufacturer instructions.
