Case Study: Raytec Linear Gen II
uploaded by Terry McDonald Business Development Manager at Thorne & Derrick
This Case Application for the Spartan Linear Generation II manufactured by Raytec and stocked and distributed in the UK by Thorne & Derrick refers to an application where the client had a requirement for hazardous area lighting in a newly segregated storage room. The area was classified as Zone 21.
Thorne & Derrick were contacted by electrical design consultant who had been employed by UK university tasked with finding a suitable ATEX light that offered the client high performance, durability and lower investment and installation costs.
The Problem
Following a DSEAR inspection, the university had been advised that they needed to separate their wood pellet storage area from their biomass plantroom due to potential risk of explosion.
A design to separate the areas was quickly prepared and T&D were asked to provide a lighting design for the newly segregated storage room by the electrical design consultant. The area was classified as Zone 21.
SPARTAN Linear Generation II
The Solution
Thorne & Derrick prepared the design using the widely anticipated new Raytec SPARTAN Generation II Linear LED fittings. Offering an improved lumen output, a similar LUX level was achieved without using the traditional high bay fittings.
The cost comparison between the number of highbays and linear fittings was only negligible but the operating costs were almost half due the improved energy efficiency of the new Generation II fittings.
Using latest software our FREE Lighting Design Service supports the upgrade from fluorescent to LED lighting focussed on maximised light output, optimised energy consumption with reliable and safe certification for explosion protection concepts in Zone 1 and Zone 2 hazardous area zones and workplaces.
The above design was complete in less than a week and the light fittings are now being manufactured ready for dispatch later this year.

Roof & Gutter Heating
Prevent Roof & Gutter Snow & Ice Build Up
Effective and thorough preparation for winter can prevent freezing pipes and damage to plant that would be financially costly and result in lost production – in previous Heat Tracing Blogs we have discussed the application of heat trace cables to provide frost protection to water pipework.
In this Blog T&D look at roof and gutter heating: the problems that poor planning can lead to and how to overcome and prepare for winter challenges with the use of heat tracing cables for the alleviation of ice and snow build-up on roofs and in down gutters.
ASK YOURSELF…..
If the answer is No to any of these questions, contact T&D to discuss your key action steps.
Snow build up on a roof can serious problems to both the roof itself and the building fabric inside as a result of thawing melt water. These are typically divided into the problems from the added weight and then the issues that arise once the snow has begun to thaw.
T&D distribute snow and ice prevention systems that reduce the build up of ice, snow and the dangers posed by heavy snow building up on roofs which can lead to structural damage. Typically these are electrically powered trace heating systems comprising of heating cables which are installed in critical areas of the roof, eaves, valleys, gutters and downspouts.
Heat tracing systems are specified to activate automatically by strategically located thermostatic and moisture detection control units that switches on the heat source whenever the ambient temperatures fall below a set point.
When snow falls and settles on the roof of a building it adds extra weight – roofing structures and designs are not typically designed to cope with all of this sudden extra weight and this can cause them to dip or bow.
This in turn adds pressure to the walls of the building.
A report from insurance provider Aviva Plc discussing “Property Precautions – Weight of Snow”, highlights the effect that added weight from snow has on the structure of a roof. These points include:
The same report from Aviva Insurance states:
“To protect against the likelihood of snow related damage to your property, it is important to develop a timely prevention and maintenance program before the winter weather commences, during and after the winter period. These simple practical measures should form part of your building maintenance program”.
The added weight of snow on a roof is far from the last of the problems caused from harsh winter weather. The next issue comes from the thawing of the snow build up.
This thaw water can quite easily overload drainage systems and cause large floods.
If freezing temperatures prevail however, the thaw water can easily re-freeze, especially at night, causing ice dams in gutters and drainage systems which in turn leads to water ingress causing internal damage to the building.
It is therefore vital that gutter heating systems are taken into account when preparing for winter.
Aviva insurance goes on to talk about Snow and Ice Roof Melting Systems stating:
“There are a range of snow and ice prevention systems available from specialist installers that can reduce the build up of ice, snow and the dangers posed by heavy snow building up on roofs which can lead to structural damage.
Snow Build Up On A Roof Over A Gutter Edge Showing Water Ingress – Caused Through Lack Of Roof Or Gutter Heating
Typically these are electrically powered heat tracing systems comprising of heated mats and cables which are routed and positioned in critical areas of the roof, eaves, valleys, gutters and downspouts etc.
Such systems are designed to activate automatically by strategically located thermostatic and moisture detection that switches on the heat source whenever the ambient temperatures fall below a set point”.
Roof and gutter heating systems are integral to preserving not only the structural integrity of buildings but also ensuring business continuity.
Thorough winterisation preparations can not only prevent damage to buildings and potential accidents involving plant workers and machinery operators but also provide a great return on investment by removing plant downtime from winter weather.
To ensure your plant or business does not fall victim to poor winter planning, T&D offer a comprehensive range of winterisation products ranging from heat tracing cable to heaters for hazardous and non-hazardous areas.
Clearing Roofs & Gutters From Snow & Ice Using Heat Tracing Systems
The most effective solution in terms of results and financial implications is to install roof and gutter trace heating cable as the cables create a flow path for the water allowing it to drain away correctly.
Key benefits of roof and gutter heat tracing installations include:
Roof & Gutter Heating Cable Layouts: 1. Roof Overhang Only. 2. Gutter and Downspouts Only. 3. Roof Overhang Plus Gutter & Downspouts
T&D are able to offer a full roof and gutter heating system design and specification, including controls and electrical loading information along with our heat tracing teams that are on hand to carry out roof and gutter heating installations.

The heat trace cable ranges stocked and supplied by Thorne & Derrick International includes electric heating cables for process temperature maintenance, pipe and vessel freeze protection and roof and gutter de-icing applications where snow and ice removal is required – cables and systems are available for commercial, industrial safe area (non-hazardous area) and hazardous area heating applications with ATEX certification.
Electric heat tracing is a cable based system used to maintain, raise temperature and protect process pipework and vessels against freezing temperatures and associated frost damage – heat tracing cables mitigate and counteract cold weather effects as part of a Winterisation strategy for industrial and process applications against low (sub-zero) ambient temperatures on both onshore and offshore locations.
Heat tracing systems utilising self-regulating, constant wattage and mineral insulated (MI) heating cables are available to provide the optimum electrical heating system for your application – we provide a trace heating system design service.

In 2021 Thorne & Derrick, the UK’s largest supplier and distributor of heat tracing cables supplied a customer with their 3,000,000th (yes, millionth) metre of frost protection cable.
3 million metres; that’s equivalent to twelve trips to the Moon or 5,000 times up and down The Shard, a 72-storey skyscraper and the UK’s tallest building that we trace heated in 2009.
2009-10 was also the coldest UK winter since 1978–79.
Coined The Big Freeze by British media, the country blanketed in snow endured polar temperatures inflicting widespread transport disruption, school closures, power outages and freezing water supplies to thousands of households, businesses and factories.
While we cannot control the weather, we can protect against the impacts – simply, heat trace cables provide guaranteed frost protection of water pipework in Winter.
Since 1985 we have prepared for the annual Beat the Big Freeze challenge, so this year we have introduced record stock levels across our range of heating cables.
3 million metres of frost protected pipework later, we continue to provide next day delivery at the most competitive prices from the largest UK stocks.
Water is Life. But it can be both a blessing and a curse…..
Pipeworks are the veins of buildings distributing water to the point of use.
But at freezing point (32°F – 0°C) water expands and changes state from a liquid to a solid (ice) – the provision of continuous water supply for people and processes is vital all year round. Frozen and burst pipes cause significant supply interruption to a wide range of commercial buildings and industrial plants. However, the annual Winter woes of ice and frost related damage caused by burst pipes can be avoided. Since 1985, Thorne & Derrick have protected pipework integrity against Winter weather damage, whether potable or process, chilled or hot water – this includes design and supply off complex multi-kilometre, major-project systems to custom heat trace cable kits for temporary site cabins.
All from the largest UK heating cable stock-holdings.
We can also support you with:
Each trace heating kit can be supplied ready to install with step-by-step instructions – simply attach the cable, linearly, to the length of the water pipe, insulate and plug in to the mains supply. Controlled by an air sensing thermostat that will activate when the ambient temperature falls below 5° Celsius the pipe heating cables will gently heat the pipe, thus preventing any standing water from freezing – our friendly and expert team of Sales Engineers or just a call away if you’re in doubt.
In the Ground & Up on the Roof
As well as protecting pipework for mechanical building services, Thorne & Derrick have the expertise to similarly Design & Supply from stocks electric trace heating systems to provide snow-melting and ice clearance for building infrastructure access and safety, including ramps and roof gutters.
