As an engineering consultancy firm, CORETEC handles the study and implementation of energy saving systems for industrial companies.
CORETEC develops tailored solutions which can be optimised to suit the customers' applications.
In particular, CORETEC can provide energy accounting systems and recovery systems or again it can work on specific development projects.
Energy accounting systems
Setting up an energy saving system starts with active and precise monitoring of the amounts of energy consumed.
CORETEC sets up fully automated energy accounting systems, which make it possible to:
- Collect, process and communicate relevant energy information
- Establish consumption rates, broken down by product or service
- Detect and monitor anomalies
- Target potential energy improvements
- Assess the effective impact of these actions
The main stages in our consultancy service are as follows:
- Analysis of energy vectors on site using the EPS method (Energy Potential Scan)
- Implementation of functional plans
- Definition of pertinent measuring points
- Definition, supplying and installation of suitable meters
- Setting up a database acquisition and feed system
- Development of automated links making it possible to use accounting data efficiently and quickly.
CORETEC is an approved Energy Expert. This means that the Walloon Region will give a 50% grant towards the setting up of an energy accounting system.
"Typical" project
- Minimum total annual energy bill of 500 k€
- Primary energy vectors: electricity, gas, diesel, heavy oil
- Secondary energy vectors: fresh water, demineralised water, steam, compressed air, etc.
Apart from the technical aspects, this type of project must be accompanied by a resolve to launch an energy improvement plan stretching over several years.
Recovery systems
CORETEC designs and installs heat recovery units on the chimney shafts.
This technique, initially developed for abattoir furnace chimneys, can be used for similar configurations without alterations being needed.
The recovered heat is used to heat the water, which is fed directly to the consumer or held in a buffer reservoir.
The recovery system can be integrated into the existing heating network, in which case a master control system is put into place to optimise the overall functioning.
A remote monitoring system and fault signal system allow for real-time monitoring of the operating parameters and make it possible to provide an efficient after-sales service.
"Typical" projects
- Annual furnace consumption - 500MWh minimum
- Fume temperatures - 150°C minimum
- The amount of power recoverable is typically in the region of 30 to 50% of the power consumed by the furnace.
- The return on investment time (ROI) varies between 2 and 5 years.
Specific developments
CORETEC has developed a great deal of know-how in the technical areas relating to energy, such as hydraulics, heat transfers, control systems, etc.
Thus it is perfectly natural that CORETEC should also develop tailored solutions for very specific problems such as the cooling of a high-powered hydraulic brake or else the pre-heating of the intake air for an aircraft engine test bench.
Only in-depth knowledge of the technologies involved makes it possible to carry out advanced energy optimisation. This mastery means we can find solutions for these specific problems while respecting precise specifications.
Instrumentation
As part of its work, CORETEC has to use measuring equipment of many different types, whether to provide for efficient control systems or carry out energy accounting, or again to count up the Green Certificates generated by its facilities.
So we have a certain command of the subject and we have invested in equipment of our own. We carry out measurement projects on site for our customers, whether as part of a feasibility study or to refine the dimensioning of the systems.
