LEDRig Lite / LEDRig PRO

UV LED curing technology for
glass fibre (GFRP) liners


The Lite and Pro versions of the LEDRig equipment make up a family of high-speed UV LED curing systems ideal for use with glass fibre reinforced polymer (GFRP) liners in the rehabilitation of sewer networks.

A revolutionary passive cooling technology allows for high efficiency of the LED modules, reaching curing speeds faster than with conventional 8x400 W UV lamps system, significantly reducing the electrical power necessary and the cost of ancillary equipment. LED technology delivers up to 65% efficiency in UV wavelength while traditional UV lamps stay on the range of 15/20%.

The range of working diameters starts at DN150 and goes up to over DN1200 in special applications.


LEDRig equipment family

LED curing from DN150 to DN600 (DN1200)

The LEDRig family of curing equipment offers glass fibre curing solutions for diameters ranging from DN150 to large diameters in special applications. The high efficiency of UV LED technology means that electricity consumption can be reduced, while the equipment can be more portable and easier to use.



LEDRig Product Range Summary

Working diameters Cable length Design No. of modules
LEDRig Lite DN150 – DN600 Up to 200 m Portable 4 UV LED modules
LEDRig PRO DN150 – DN1200(+) Up to 1000 m Truck-mounted 8 UV LED modules





LEDRig Lite
LEDRig Lite


LEDRig Lite, the portable version of the equipment in this family, has a 100 m (200 m in option) long umbilical cable mounded on a reel fitted with wheels so that it can be transported to the work site. A compact control unit integrated in the cable reel supplies power to the four UV LED modules that make up a compact array offering UV power of 1200 W. LEDRig Lite is suitable for application in diameters ranging from DN150 to DN600.


Curing speeds


The LEDRig Lite curing system is designed to be versatile and the same time offer optimal curing speeds for its size and weight. These speeds will depend on the liner diameter and thickness. All these values are provided as a guide and may vary significantly depending on the type of liner.


Passive cooling


LEDRig Lite features a patented design for the passive cooling of the LED curing modules. It avoids the use of compressed air inside the umbilical cable by using a set of especially designed lobes to dissipate the heat produced by the LED. The number, dimensions and shape of these lobes have been studied to ensure optimal transfer of energy to air in the conduction. This is normally done by an air blower in glass fibre liner curing jobs.

LEDRig PRO
LEDRig PRO


The LEDRig PRO system is designed for curing glass fibre liners in the rehabilitation of sewage systems. It is fitted with eight UV LED modules up to DN600, giving hi-efficiency and providing sufficient UV radiation to cure large diameters satisfactorily. Technology is more than three times more efficient than traditional lamp-based technology, which means that larger working diameters can be covered using less power, in combination with a very significant increase in curing speeds. Depending on the diameter and type of liner, LEDRig doubles or even triples habitual industry speeds. Electricity consumption is also reduced by a factor of 4, minimizing the cost and size of the electrical generator to operate on site.


Working diameters


The system is made up of two LED chains with the object of covering a wide range of working diameters, and comes with a set of centring elements designed to optimize the curing process in this range. A second chain makes it possible to work with diameters ranging from DN400 to DN1200 with suitable accessories. The power and efficiency of the LED modules now lets previously unknown limits be reached.


Working lengths


LEDRig PRO powers the LED modules using direct current. This, together with the lower (more than 3 times to compare to ub bulb) working power requirements, means that the diameter of the LEDRig Plus umbilical cable conductors can be reduced. Up to 1000 m of cable can be installed for special applications.


Passive cooling


LEDRig PRO features a patented design for the passive cooling of the LED curing modules. It avoids the use of compressed air inside the umbilical cable by using a set of especially designed lobes to dissipate the heat produced by the LED. The number, dimensions and shape of these lobes have been studied to ensure optimal transfer of energy to air in the conduction. This is normally done by an air blower in glass fibre liner curing jobs. A set of 4 temperature sensors (3 infrared sensors and 1 thermocouple) monitor constantly monitor the key variables of the system operation and of the curing process.


Curing speeds


The LEDRig PRO curing system is designed to optimize liner curing processes by increasing speeds beyond 2.5 m/minute (in DN300) or 3 m/min (in DN150). These speeds will depend on the liner diameter and thickness. All these values are provided as a guide and may vary significantly depending on the type of liner.
