HSR Self-Regulating Heating Cable
SOLCO PYROELEC HSR is a self-regulating trace heating cable designed for freeze protection and temperature maintenance.
SOLCO PYROELEC specifies HSR for freeze protection of water pipelines, temperature maintenance in petrochemical and gas plants, and suitable hazardous Ex applications.
HSR automatically changes its thermal performance in response to temperature and provides independent heat-output control along the length of the cable.
What Is HSR Heating Cable Used For?
The HSR range is designed for applications where electrical trace heating is required for freeze protection or temperature maintenance.
Water Pipeline Freeze Protection
SOLCO PYROELEC specifically lists freeze protection of water pipelines as an HSR application.
Process Temperature Maintenance
HSR is also specified for temperature maintenance within petrochemical and gas plants.
Hazardous Ex Locations
SOLCO PYROELEC lists the HSR range for suitable hazardous Ex applications.
How Does HSR Self-Regulating Cable Work?
HSR changes its thermal performance in response to temperature and provides independent heat-output control along the cable.
Temperature Changes
The heating requirement changes as the temperature around the cable changes.
Cable Self-Regulates
HSR changes its thermal performance automatically in response to the temperature around the cable.
Independent Heat Output
Heat output is independently controlled along the length of the heating cable.
HSR Key Features
Thermal performance changes automatically in response to temperature.
Heat output is independently controlled along the cable length.
SOLCO PYROELEC states that HSR will not burn or overheat, even when overlapped.
Cable can be cut to the required length to suit installation conditions.
The manufacturer states that soft power switching improves energy efficiency and contributes to longer service life.
Designed for straightforward powering and splicing.
Available from Insulation & More in 10, 16, 24 and 30W/m versions.
The HSR-CP cable supplied by Insulation & More uses the FR polyolefin outer-jacket configuration.
