Trace Heating

Process

Trace heating requirements are often complex and require competent specialist integration into a number of the project disciplines.

Trace Heating

Customers can spend a considerable amount of time and money in preparing specifications, issuing enquiries and reviewing tenders for both technical and commercial content.

Items to be considered

End user specification
Engineering/Process contractor specification
International standards appropriate to the installation
National standards appropriate to the installation
Area Classification if potentially explosive atmosphere (Zone, Category, ‘T’ Classification)
Process Requirements
Control Philosophy
Site layout
Installation methods & maintenance requirements
Documentation requirements
Financial considerations

Hertel is in a unique position to provide clients with an independent review of the above. With a vast amount of experience in the trace heating industry, Hertel are able to offer:

Knowledge of and involvement with, the latest national & international standards.

Full electrical cable and wiring services associated with a full trace heating service, including major and secondary cable containment, ladders and traywork

Specification & Design

Experienced engineers calculate the performance and energy requirements of your plant and equipment, including heat loss calculations and calculation of optimum insulation thickness. From this information the optimum heating system is developed.

In addition to our own in house software, Hertel have access (under license) to the bespoke software of most major manufacturers.

Control Systems

The control philosophy and selection of equipment is critical to the correct function of any trace heating system, it is for this reason that Hertel provide as part of a total package a full control system design, supply and installation service.

Regardless of how basic or complex the requirements may be, a full drawing package is provided for comment prior to fabrication. These would be revised to as built status for issue with the O&M manuals.

Installation, Commissioning & Support

Hertel can install your complete trace heating system for you, alternatively we would be happy to provide supervisors and a commissioning engineering team that would ensure the quality of the Hertel design is maintained.

After completion of the installation, Hertel offer a full commissioning service whereby all functions and processes are tested in compliance with the relevant norms and directives. Our engineers complete all of the relevant commissioning documentation that is incorporated into the O&M system manuals.

Post Installation Support

We provide a full back up and support service throughout the full lifecycle of plants and installations to ensure that the maximum life expectancy of trace heating systems is achieved, this may include modifications and/or repairs to systems including the updating of documentation.

Site Surveys and Inspections

Hertel can carry out a complete survey of an existing installation on your site and evaluate for compliance with current best practices and directives. Hertel can supply a written or verbal report that provides the basis for any future design and/or installation works that may be carried out.

In addition we have Compex trained personnel qualified to carry out installations and testing in hazardous areas with all of our design, equiment and documentation in full compliance with ATEX and low voltage directives.

We are NICEIC approved, and FPAL and UVDB registered for the design, supply and installation of electric trace heating systems.
