Applicability - Bartec PSB Design Manual

Applicability

This document covers the design of BARTEC PSB and MSB trace heating systems. It includes mainly engineering procedures for certified com-
ponents as set out in section System design.
The manuals shipped together with the individual components will contain additional relevant content to this document.
Relevancy of individual sections of this document is highlighted at the beginning of each section.
The self-regulating trace heating system type 27-1S** is a trace heating system for fixed installation in hazardous areas with explosive gas, va-
pour or dust atmosphere. It is to be used for frost protection, to raise or maintain the temperature of a workpiece where it is externally applied.
CAUTION
The trace heating system is only applicable in case of workpiece temperature is higher than the layout ambient temperature.
WARNING
Risk of fire or electrical shock.
Risk of lost explosion protection.
The maximum Trace heater stady-state current is to be observed!
Protecting of all components of the Trace heater Installation Enclosure against over-heat is controlled by maximum Heating circuit length, depending
on design parameters.
Observe the trace heater stady state current listed on table "Installation Enclosures for Trace Heating as Power Box kit"!
