The Powerblanket/Thermon HSL2000 Heated Sample Line leverages Thermon self-regulating or power-limiting heat cable to deliver reliable temperature maintenance and freeze protection—even under changing ambient conditions. HSL2000 is purpose-built for ordinary and hazardous areas (Zones 1, 2, 21, 22), making it a strong choice for fixed CEMS, field RATA work, midstream gas sampling, and semiconductor/process umbilicals. Typical heated lengths are 0.5–30 m (1.5–100 ft) with a 100 mm (4 in.) minimum bend radius. With proper control, HSL2000 supports maintenance temperatures up to 200 °C (400 °F) and standard Type K feedback, with RTD/Thermistor options to match your control hardware. Available configurations include:
  • Heat cable families: self-regulating and power-limiting options at common watt/ft classes
  • Outer jackets & insulation: Corrugated or braided shells; closed-cell foam or felt insulation (to 1/2")
  • Terminations & plugs: Multiple power/sensor lead lengths; Molex/Amphenol/Leviton plug styles
  • Tube materials & fittings: PFA (standard) with swaged or compression fittings; optional quick-connects; raw ends
Product Highlights
  • Hazardous-area ready: designed for use in Zone 1/2/21/22 applications (see heater cable approvals)
  • Up to 200 °C (400 °F) maintain with compatible controllers
  • 5–20 W/ft custom power density classes to fit ambient and setpoint needs
  • High flexibility: ≤100 mm bend radius; rugged jacket options for field work
  • Heated length: 0.5–30 m (1.5–100 ft) typical; optimized for short runs under 50 ft
Across the line, HSL2000 pairs self-regulating safety with Thermon-grade components to reduce risk of hot spots and simplify installation, supported by controller options and industrial connectors for a clean, reliable setup.
  • Self-regulating/power-limiting technology that reduces output as temperature rises, ideal for variable ambient and overlapping runs.
  • Hazardous-area suitability for Zones 1, 2, 21, 22 when built with approved heat cables and terminations.
  • Flexible routing with ≤100 mm bend radius for compact installations.
  • Custom power density (5–20 W/ft) and multi-voltage (120/208/240/277 VAC) to match site power.
  • Closed-loop ready: Type K standard; RTD/Thermistor/Type J options for your control strategy.
  • Rugged jackets & insulation (corrugated or braided; closed-cell foam/felt) for durability and personnel protection.
  • Heated lengths typically 0.5–30 m for fast-turn, short-run projects.

Why choose Powerblanket HSL2000?

Key Benefits of Using Powerblanket HSL2000
