Robotic Demolition
Safety, precision and efficiency in refractory demolition work
At Alfran, we incorporate advanced robotic demolition solutions to optimize maintenance work in demanding industrial facilities.
This technology allows for safer, more precise, and more efficient work on refractory linings, reducing direct human exposure to hazardous environments.
Ground-operated demolition equipment with platforms
We have robotic demolition machinery from various manufacturers, designed to work across different industries, particularly for operations involving refractory castings, bricks and concrete. This equipment helps to reduce the risk of accidents, minimise human fatigue by reducing the need for manual labour, and improve completion times during plant shutdowns.
Among the equipment used by Alfran, we have various sizes depending on the access and working area. We currently have 20 units distributed around the world across Europe, the Americas, Africa and the Middle East.
Aerial Demolition Equipment with CastBreaker (CDD)
For work on vertical structures, in hard-to-reach areas or on equipment where the use of scaffolding or platforms is not feasible, Alfran offers innovative, in-house designed solutions for robotic demolition suspended by a hoist.
The CastBreaker Demolition Device (CDD) is a piece of equipment designed using advanced technology to operate whilst suspended in the air, enabling refractory demolition tasks to be carried out with a high level of safety, control and efficiency.
This system facilitates work on complex industrial equipment without the need for platforms or scaffolding, reducing execution times, minimising risks and enabling more precise work in confined spaces or vertical environments. We currently have three units in operation, located in the USA, Mexico and Spain.
01
Remote Control
It minimizes the operator’s direct exposure and reduces the risks associated with manual demolition work.
02
Time optimization
It allows planning and reducing intervention times during plant shutdowns.
03
Efficiency and precision
It improves demolition performance while maintaining a high degree of control over the work area.
04
Less need for auxiliary equipment
It reduces dependence on scaffolding, platforms, or complex access.
05
Greater operational safety
It allows inspection and action in hard-to-reach areas with less human exposure
Diagnosis and evaluation of coatings
thermographic analysis
Infrared thermography is a tool that has been expanding over time in the preventive and predictive industrial maintenance of different equipment.
Take advantage of the properties of infrared radiation to draw useful conclusions about the condition of the equipment under test. Inspections take less time than repairs, especially when performed with a thermal imaging camera.
Monitoring equipment performance with thermal imaging cameras can reduce the likelihood of unexpected equipment downtime, lower reactive maintenance fees and equipment repair costs, and extend the lifespan of industrial machinery assets.
Thermal imaging is excellent for detecting non-uniformity in equipment, as it indicates hot and cold spots in surface temperature by capturing infrared images.
types of refractory materials
ACID REFRACTORIES
Ideal for specific environments where chemical resistance is required, mainly made from silica.
BASIC REFRACTORIES
Made primarily from magnesium, they guarantee resistance to high temperatures and extreme chemical conditions.
NEUTRAL REFRACTORY
Versatile materials such as alumina refractories that offer excellent mechanical and chemical resistance.
Technical characteristics of our materials
High resistance to high temperatures
Our materials offer exceptional performance even under extreme thermal conditions.
Low thermal conductivity
We ensure efficient insulation that reduces energy losses and improves performance.
Chemical inertia
We guarantee that our materials maintain their properties even in highly corrosive environments.
Low coefficient of expansion
Our products remain dimensionally stable, ensuring less wear and a longer lifespan.
PATENTED SYSTEM
We have developed our own patented system, ALFRANJET, generally called SHOTCRETING, which involves 100% wet-mix pumping and high-speed spraying of heat-resistant concrete with and without aluminous cement, and without dust or waste. We have a long list of international references from multinational clients.
