Compact 110 - 150

A.S.T. presents the Compact Solar Panel System with its unique Quality and Performance features.
Compact is the result of years of research by A.S.T.'s research staff, working closely with international centers, in order to incorporate the following latest technologies:

• Air Vacuum
• LASER welding and
• Compact Natural Circulation Solar Systems, which means that the Solar Panels and the Boiler form a single unit.
  
  Advantages
  
  
• Stainless Steel Boiler (INOX316L.)
• Selective High-Performance Panels.
• Copper Absorber & Tubing.
• Unit operation in an Air Vacuum.
• LASER Welding of the Absorber's Copper Tubing.
• Heat transfer with Ethyl Alcohol, which evaporates quickly due to its low boiling point.
• Unbreakable Crystal (SECURIT).
• Very fast performance, even in low sunlight, due to the system's low control inertia.
• Heat exchanger built into the Boiler, which immediately returns the steam energy from the Ethyl Alcohol.
• Maximum productivity in warm water in the same amount of time.
• Minimal heat loss due to the system's compact design.
• Pioneering Construction and Stylish Design.
• Space & piping efficiency.
• Excellent Energy Characteristics and Uninterrupted Performance throughout the years.
• Extreme frost resistance (up to -6o°C).
• Doesn't require additional antifreeze or replacement.
• Installation can be expanded, depending on the requirements.
• Easy installation.
• Guaranteed Return of Investment.
• High Thermal Capacity
• Prevents Nighttime Flow Reversal.
  
  Mode of operation
  
  The COMPACT Thermal System's copper tubing is welded using LASER technology, which increases the thermal capacity of the entire system. Next, Ethyl Alcohol is injected into the Copper Tubing, which is sealed in an Ah* Vacuum. Solar energy heats the Ethyl Alcohol, which in turn evaporates easily due to its low boiling point. The steam which is produced (through the Air Vacuum Piping), is channeled directly into the Exchanger in the Boiler, transferring the heat that it conveys. This way, the steam is vaporized and then returns to the Panels due to its gravity.
  
  Stainless steel boiler
  
  
• Stainless Steel Boiler (INOX316L).
• Selective High-Performance Panels.
• The Boiler's insulation is a combination of 30mm thick Polyurethane (environment-friendly) with a density of 4oKg/m3 and 30mm thick fiberglass.
• Reinforced Propylene Boiler Casing.
• 4KW Special Alloy INCOLOY 825 Electric Resistance (resistant to water with a high chlorine concentration).
• Sacrificial Protection.
  
  Economy - Environment
  
  
• Savings of 1,200 - 1,800 KWh annually.
• The perfect solution for a family's hot water needs.
• Emissions reduction of at least 2 tons CO2 annually
  
  Results
  
  
• High Water Temperatures (Stagnation temperature 180°C) even in difficult weather conditions.
• World-wide Leading Performance Curve (according to measurements ).
