LARGE-SCALE SOLAR-POWERED HEATING SYSTEMS

Natural, renewable, inexhaustible ~ Solar energy is not subject to the variations of the international economic situation. Once the initial investment has been made, the rest is free. Major savings can be made compared with conventional energy, in complete confidence and over the long term. The sun will not send you a bill. It is a naturally clean form of energy: no smoke, no noise, no waste products, making a key contribution to the fight against the greenhouse effect which poses a threat to our planet.

ESE, the specialist in large-scale installations ~ Designing and manufacturing solar heating systems since 1987, ESE is renowned for its experience in this sector. ESE is the specialist in drainback systems for large-scale installations. ESE solutions are frequently chosen by owners of large buildings (apartment blocks, public swimming pools, care homes, etc.) and by companies (hotel chains, carwash facilities, etc.) who are in search of quality and performance. Why choose ESE? ® Drainback technology - the solution for largescale systems ® Many testimonies ® Standard range for large projects

The IlLaw flow" drainback system in a clased loop systern-â An ideal method of operation for system longevity and safety ESE pioneered the introduction of the drainback system in closed loop system to avoid the problems of over-heating encountered with "conventional" systems. ~ Principle of drainback system QWhen the system is not operating for whatever reason - thermostat , temperature reached, power eut, night-time, high temperature cutout - the drainback ensures that the collectors and the pipes are [j empty of fluid. The system is in passive safe mode, the best guarantee of safety. When...

Benefits +1 Safety Compared to a pressurised system, drainback solar circuits guarantee even greater safety for the user. As soon as your heating system is turned off, the collectors are emptied of fluid which means optimum protection for the heat-transfer fluid against overheating and frost. Maintenance The fact that the fluid and the system suffer a lot less means considerable maintenance savings, in terms of both labour and parts that can be subject to heavy wear and tear. Optimum size Unaffected by overheating or frost, ESE systems are perfectly sized for the most economical performance...

ESE product range for large-scale installations The Ecosol2.32 collector The Ecosol2.32 fiat collector is the result of ESE'scontinuous technical development programme. The exceptionally high performance achived with this collector is due to a number of major innovations: The selectivecoating on the "Epsilon"absorber is appliedto a copper sheet undervacuum, producinga high levelof performance:absorption = 95% and emissivity= 4%. The "Solsnake" absorber comprises a fiat sheet ultrasonically welded to a copper tubing system in the form on a continuous coil, producing optimum heat exchange due...

A solution for every type of roof Our solar collectors can be installed on top of the roof or built into it; we even instail on fiat roofs. Whether you have a tile or slate roof, we have the solution that suits your needs. An optional installation kit can be supplied with our built-in Ecosol 2.32 collectors. Integrated On fiat roof On sloping roofs, you can choose a surface-mounted configuration with 1,2 or 3 collectors in a row, or a builtin configuration which comes with our installation kit. Our fiat roof systems come in a 1, 2 or 3 collector option and can be mounted at an incline of...

Solar stations Dynasol-Domosol The solar station is the interface between the solar collectors and the hot water tank. It comprises a solar circulation system (pump and control unit) and the drainage tank. ESE offers solutions for systems up to and above 1000 m2. Dynasol "Modulo" (4 - 30 collectors) Made of 2 separate pre-assembled parts, the very design of this system offers increased modularity without sacrificing speed or simplicity. Two wall fixings allow for optimal use of space in the boiler room. Dynasol "Compact" (14 - 30 collectors) Pre-mounted on a steel base in order to keep the...

Solar Energy Guarantee Since the 1990's, ESE has been helping develop the concept of a "Solar Energy Guarantee". In practice, this concept guarantees an annual supply of energy for the user, who will receive recompense if the targets are not achieved. ln order to ensure this guarantee, ESEhas developed a remote measuring and monitoring system. This system continuously measures the parameters at which the solar energy system is operating, and regularly transmits the operating data and energy production levels to ESE. ln this way, ESE can check that your system is working weil and is in the...
