Description
Thermon SafeTrace® DLS Steam Tracer
Energy-Efficient Steam Tracing with Enhanced Personnel Safety
The Thermon SafeTrace® DLS (Distributed Low-output System) is an advanced steam tracing solution engineered to provide predictable, energy-efficient process heating while significantly reducing personnel burn hazards. Unlike conventional bare steam tracer tubes that often create localized hot spots and excessive pipe temperatures, SafeTrace DLS utilizes a patented composite insulation system to deliver controlled and uniform heat transfer along the entire pipeline.
SafeTrace DLS is ideal for low to moderate process temperature maintenance, freeze protection, and viscosity control where energy efficiency, operator safety, and long circuit lengths are important design objectives.
Product Overview
SafeTrace DLS consists of a copper or stainless-steel tracer tube surrounded by specially engineered composite materials that intentionally reduce thermal conductivity. This controlled heat transfer produces a consistent heat output, preventing overheating while improving steam utilization.
Unlike bare steam tracers that may waste energy by overheating sections of pipe, SafeTrace DLS delivers a stable thermal profile, reducing thermal stress on piping systems and improving overall operating efficiency.
Key Features
- Predictable and uniform heat output
- Up to 50% lower steam consumption compared with bare metallic steam tracers
- Composite thermal barrier minimizes overheating
- Significantly reduces personnel burn hazards
- Safety yellow identification jacket
- Copper or stainless steel construction
- Long continuous coil lengths
- Fewer steam traps required
- Simple tape-on installation
- Compatible with Thermon steam tracing accessories
- Suitable for new installations and retrofit projects.
Construction
SafeTrace DLS incorporates four engineered layers:
- Copper or Stainless Steel tracer tube
- Thermal retardant layer
- Heat reflective tape
- Safety yellow polymer jacket
This multi-layer construction carefully controls the heat transferred from the steam tracer to the process pipe, delivering efficient heating while keeping the outer jacket temperature below the personnel contact limit defined by ASTM C1055 under recommended operating conditions.

Benefits
SafeTrace DLS provides several operational advantages over traditional steam tracing systems:
Improved Energy Efficiency
The composite thermal barrier reduces unnecessary heat loss and can lower steam consumption by up to 50% compared with conventional bare metallic tracers.
Enhanced Personnel Safety
The safety jacket is designed to maintain an accessible surface temperature below 58°C under specified operating conditions, reducing the risk of accidental burns and supporting compliance with ASTM C1055.
Predictable Heat Transfer
Controlled heat output eliminates localized overheating and reduces thermal stress on process piping.
Lower Installation Cost
Long continuous coils allow installation directly from the steam supply manifold to the condensate return manifold, reducing the number of fittings and steam traps required.
Lower Maintenance
Fewer mechanical connections mean fewer potential leak points and lower lifecycle maintenance costs.
Typical Applications
SafeTrace DLS is commonly used for:
- Freeze protection
- Water lines
- Utility piping
- Chemical process piping
- Instrument impulse lines
- Tank farm piping
- Food and beverage processing
- Pharmaceutical facilities
- Petrochemical plants
- Refineries
- LNG terminals
- Industrial utility systems
Its controlled heat output makes it particularly suitable for applications where moderate process temperatures are required and excessive heating must be avoided.
Installation
SafeTrace DLS is supplied in long continuous coils and is typically attached directly to the process pipe using Thermon FT-1H Fixing Tape. Steam supply and condensate return connections can be made using ThermoTube® pre-insulated tubing and standard Thermon steam tracing accessories, simplifying installation while improving system reliability.
SafeTrace DLS vs Conventional Bare Steam Tracing

|---|---|---|
| Heat Transfer | Controlled and uniform | High, often uneven |
| Energy Consumption | Up to 50% lower | Higher |
| Hot Spots | Greatly reduced | Common |
| Personnel Safety | Jacket temperature <58°C (typical) | High burn risk |
| Steam Trap Requirement | Fewer | More |
| Installation | Faster | More labor-intensive |
| Maintenance | Lower | Higher |
Why Choose Thermon SafeTrace DLS?
SafeTrace DLS combines energy efficiency, predictable heating performance, and personnel safety in a single engineered steam tracing solution. By replacing conventional bare metallic tracers with a controlled heat-transfer design, it minimizes overheating, lowers steam consumption, reduces operating costs, and enhances plant safety.
For industrial facilities seeking a reliable steam tracing solution with lower total cost of ownership, SafeTrace DLS is an excellent choice for both new construction and retrofit projects.
