Flexible hoses for temperature critical materials
Isopad Flexible Heated Hoses, from Tyco Thermal Controls, offer resistance to the high temperatures, pressures and aggressive materials often present in processing plant.
Raychem VPL Cable provides dependable temperature maintenance to 150degC and will withstand continuous exposure temperatures of 250degC, when de-energised.
VPL's power output at high temperatures exceeds the thermal ratings of self-regulating heating cables.
Where high maintenance temperatures are required, a single pass of cable may be sufficient to offset the pipe heat loss, when alternative cable types require multiple passes.
Additionally, VPL's low inrush current reduces breaker size and power distribution wiring.
The power limiting output allows VPL Cable to be overlapped once without any risk of overheating, as the positive temperature coefficient effect (PTC) of the heating element reduces power output as the ambient temperature increases, effectively reducing the temperature of the cable at the points of overlap.
The new, flexible VPL Cable is easy to install on metal pipes, tanks and vessels and is ideal for a wide range of frost protection and process temperature maintenance applications requiring high output and/or high temperature exposure.
It carries EECS (BASEEFA), FM and CSA Approvals for use in hazardous areas.
The introduction of the Raychem VPL Power-Limiting Heating Cable is the first in a series of innovative heat-tracing product and system introductions that Tyco Thermal Controls is planning to roll-out over the coming months, underlining its commitment to offer customers advanced products and optimum solutions for superior project execution.
