3 Principle & Technology High selective coated receiver pipe with secondary mirrow. The concetration of sun rays is 40 times. Direct conversion of solar power into steam energy CSP Concentrated Solar Power Linear Fresnel system Flat narrow mirror strips focus the sunlight onto a receiver pipe The mirror strips are turned by drive and control with high precision according to the tracking of the sun during the day Water is heated up and evaporated in the receiver CSP-Panel: focused, swivel-mounted mirror strips with drive and control preassembled and tested on a panel ready for installation Photo rights: FRESNEX GmbH, Wiener Neudorf For process steam up to 250 ºC The high precise tracking controll of mirrow strips enables direct evaporahon of water in the receiver pipe. Case Study: KWIZDA Agro, Austria KWIZDA in Leobendorf nearby Vienna is one of the first solar steam projects in Austria with a collector size of 384m². During a summer day the starting time is around 20 minutes only. Means 20 minutes after sun rise the solar steam production is under operation. The starting time in the winter season is max. 1,5 hours and for bad weather condition with temperatures below zero an anti-freeze system is protecting the all CSP components. The collector field efficiency of 29% related to the annual direct normal irradiation generates MWh per year. Due to less consumption of the factory on Sundays, the consumed solar steam is between 105 and 110 MWh per years. 108 MWh annual savings

4 Layout of 312 m 2 CSP field. Case Study: Fish Cane Factory, Croatia The village Sali in south of the island Dugi Otok in Croatia is a perfect location to generate solar steam for energy savings. On the one hand this place enjoys excellent solar irradiation and on the other hand the energy costs are higher because of the island location. The peak steam production is more than 200 kg/h for a CSP-field of 312m². Finally the customer can safe more than ltr oil and relieves the environment by a CO 2 reduction of 44 ton per year. 15,000 liter oil saving Hybrid concept With the innovative modular CSP-Panels the proven technology of large CSP power plants is now also available for the industry using a market concept similar to the one for conventional flat plate collectors. Closing a market gap in the solar business with many applications. The system is used beside an existing steam boiler => fossil fuel cost reduction by substitution During sunny periods the solar system delivers steam, the existing boiler load can be reduced In cases of an existing lack of capacity, the solar steam system can help to increase production Photo rights: Shutterstock 2016

5 Solar steam generation Energy cost reduction Golden End - free energy source after payback period Completely pre-assembled modularpanels for fast installation designed for the industrial application Perfect suitable for rooftop installation Automated unattended operation Patented, revolutionary solar technology Guaranteed efficiency Low weight (35-30 kg/m 2 ) CO 2 reduction Pre-assembled unit designed for industrial applications Solar steam generation via concentrated sunlight has big advantages. Return of investment Solar Steam Systems (Laundries, Food-, Textile- & Chemical Industry, etc.) Peak Output:* kg steam ,500 Annual Solar Steam: ton ,110 2,069 Savings in MWh: MWh ,445 Collector Surface: m² ,200 2,200 Steam Tank: liter ,500 2,800 Project costs:** EUR 176, , , ,000 Savings per year: EUR 11,400 18,400 29,300 54,600 Return of Investment (ROI): Years * The peak output refers to the maximum performance during the noon time at a clear sky. ** EPC basis without custom duties and sales tax. basic data Location: Lahore Feed hot water temperature: 90ºC Oil price: 33 PKR per liter Efficiency of supported boiler: 80% Operation: 7 day a week Energy price increase: 3% p.a.

6 System integration The system can be easily integrated into a conventional process steam boiler system. ECOTHERM as solution provider offers all relevant working steps for full system integration and operational readiness. Fresnel collector (CSP) Power regulation & pressure control Feed-in to steam header Product USP our advantages Pre-assembled mirror module including drive and control Transport in compact units Easy to install Low area exposed to wind Low surface loading Perfect suitable for roof-top installation Mirrors easy to clean due to flat structure Same efficiency but lower system cost compared to competition Plants of individual size consist of several modules of 13m² mirror surface Most efficient option to use the power of the sun for industrial applications Guaranteed system efficiency Performance of the collector is certified according ISO 9806:2013 by AIT (Austrian Institute of Technology) Vienna. Based on the load profile provided by the customer, the system efficiency and annual solar gain will be calculated by ECOTHERM. If the guaranteed energy cannot be achieved, ECO- THERM will provide additional CSP-modules to compensate the balance energy for free. Upt to 50% energy saving The solar gain can cover 50% of the overage steam demand of a daytime operated factory. Up to 100% roof utilization Due to the moderate module size of 13 m 2, available roof areas can be utilized up to 100% compared to fresnel collectors of our competition. Automated unattended operation Efficient and safe operation by automatic power and pressure control unit. 100% overheat protection also in case of power stortage. Energy monitoring Hourly, daily, monthly and annual solar steam production will be monitored and shown on the display and can be recalled by the web. Easy installation Preassembled mirrow modules and the ready made pressure control unit makes this system the fastest fresnel-system of the world.
