Overview


Intral is a fully integrated lighting trunking system with extruded aluminium profile, highly efficient luminaires, pre-wired internal cables and plug-in connectors. Flexible luminaire positioning and the ability to fine-tune light output result in optimum design solutions for most Industrial projects.

There is no need to fit luminaires into the trunking on site as each section of the Intral system is delivered pre-assembled and labelled with project specific codes for a quick and easy installation. Minimal packaging ensures a low environmental impact and reduced time in waste removal.

Intral uses high quality components for long life and maximum energy efficiency. Aluminium profiles ensure rigid light-lines and produce lower internal temperatures than steel systems. This form of  thermal management  lengthens the life expectancy of wiring, drivers and other components therefore minimising failures caused by over-heating.

At Whitecroft, our BIM engineers are not only adept at using Autodesk Revit; they are also fully trained lighting designers. We believe this is essential. When you use our teams on your project, you can rest assured the whole lighting solution is being designed, assessed and managed by people who know the technology inside out and have a full understanding of your requirements.

- We can populate your BIM model with a full lighting design.

- All our BIM families are created in-house, so if bespoke models are required, we can deliver them.

- We use Relux to create design validation data that confirms your project’s compliance and supports your BIM model.

- Once the model is complete, we work with you to interrogate every element including quantity schedules, costs, energy validation, COBie data and delivery schedules.
