Introduction
Collectors
Thermo siphon systems
Multi Flow - 35 risers by pressing process
• Large relation between internal flow surface and
outer surface
• Low pressure drop (perfect for thermosyphon)
• Minimum energy loss
• Low pressure resistance (0,8 bar)
Nickel plated Steel-Base material
• Protects base material against corrosion
• Nickel can withstand high temperatures
Black-Chrome selective top layer (Kf)
• High solar absorption  = 0.93
• Low Emission  = 0.12
• Resistant against high temperatures
• Long experience in the field

Introducing Streamline
Solahart Streamline
Solahart Streamline
How the Streamline Works
The solar control unit receives constant
temperature information from a hot sensor
located in the hot return line of the collector and
a cold sensor located at the storage tank.
When a temperature differential of greater than
8°C is encountered the circulating pump is
activated and cold water is pumped from the
bottom of the storage tank to the base of the
collectors.
As the water is heated it passes to the top of the
collectors where it is returned to storage heater
This process continues until the temperature
differential falls to less than 4°C.
Cold water is pumped
to base of collectors.
