3. SECUSOL The Solar Thermal Appliances + SECUSOL + the 4.5 KW heating element replaces any conventional water heater! = Solar Appliances

4. SECUSOL The Solar Thermal Applicances Sunarc-Antireflex Glass (AR) No de-arreator required Anodized Aluminium frame „ Matched flow“ solar control Full surface copper absorber with highly selective vacuum coating Heat resistant ultra sonic welding 2.5‘‘insulation Dual phase heat exchanger Combined filling and circulation pump

6. SECUSOL Tank Options 66 gal tank - One solar Heat Exchanger (HX) - One back-up HX - SUNGO US plus - With 3‘‘ insulation 92 gal tank - One solar HX - One back-up HX - SUNGO US plus - With 3‘‘ insulation

7. SECUSOL Simplicity of Installation and Setup Reduced mounting and component costs by 50%

8. SECUSOL The Solar Appliances The SECUSOL system is pre-engineered and pre-wired. That makes it is easy to install and reduces potential mistakes. The Wagner SECUSOL system can completely replace your conventional direct water heater.

10. SECUSOL Mounting Options Flush mount Free standing

14. SECUSOL - The Easy Way to Avoid Stagnation Problems Protect solar liquid from overheating

16. T1: 80 °F SECUSOL System Sunction Early Morning Situation T2: 55 °F When the system is not running, no solar liquid is in the collector. The liquid stays in the HX. In case of a power blackout there will be no overheat issue.

17. SECUSOL System Function Morning Situation T1: 85 °F T2: 55 °F System kicks on when delta T between collector and lower tank is at 30°F. Filling mode: Pump speed at 100% for the first 2 minutes. Heat transfer liquid is pumped up to the collector. The air is forced into the upper part of the HX.

18. SECUSOL System Function Morning Situation T1: 67 °F T2: 57 °F After the filling time the pump goes into the speed controlled mode. That saves electric energy and increases the efficiency. In the oversized heat exchanger is enough space for both, a perfect heat transfer and expansion.

19. SECUSOL System Function Situation around Noon T1: 203 °F T2: 159 °F When collector temperature rises, pump speed increases to maintain the standard delta T of 40 °F. The system will stop when either the max. tank temperature (160F) or the max. collector temperature (240F) is reached. Or when the delta T drops below 10°F.

20. SECUSOL System Function Afternoon Situation T1: 203 °F T2: 160 °F When the pump stops, the solar liquid will drain back into the heat exchanger. The collector remains empty.

21. SECUSOL System Function Afternoon Situation T1: 203 °F T2: 160 °F The air will rise up into the collector while the solar liquid drains down into the heat exchanger. Overheating will never occur with SECUSOL! Max. tank temperature is reached. System stops!

22. SECUSOL System Function Afternoon Situation T1: 406°F T2: 160 °F Note: Our collector can easily handle temperatures way over 400 °F.

24. SECUSOL System Function Winter Situation – with Overcast Sky T1: 34°F T2: 55°F When there is no solar yield, the 4.5 kW heating element will provide all the heat needed for shower, dishwasher etc. Just like any other water heater. T3: 155°F

25. SECUSOL System Function Winter Situation – with Overcast Sky T1: 34°F T2: 55°F You could also use the upper HX and hook up your oil or gas boiler as a back-up for the winter. T3: 155°F

27. SECUSOL Preheat Appliance Situation with no Solar Yield T1: 23 °F T2: 55F T: 155F When there is no solar yield, the water coming from the street will just pass the SECUSOL tank. It will be heated up as usual by the conven-tional water heater.

28. SECUSOL Preheat Appliance Situation with Solar Yield (Winter or Summer) T1: 190 °F T2: 150F T3: 160F T: 155F In normal operation, the street water will be pre-heated in the SECUSOL tank. Most of the year the conven-tional water heater does not have to fire. The heat will then be provided just by the sun!
