No screws or rivets are used in the frame for a clean finish. Permanently sealed and high stability through all-around folded aluminum frame and endless glass seal. Universal application on flat, sloped roofs or freestanding, vertical (model SV) or horizontal (model SH) orientation. Model SH is suitable for installations on walls. Connect up to 12 collectors in one array for commercial or residential systems. Fast installation with flexible connection pipes and quick-connect fittings. Prefabricated collector mounting hardware ensures easy connection to roofs. Maximum system performance and reliability with a full range of solar system components designed to integrate seamlessly. Quality tested to Solar Keymark testing requirements. Certified to the Solar Rating and Certification Corporation (SRCC) OG-100 Standard.

Construction and function The main component of the Vitosol 100-FM is the ThermProtect switching absorber. It ensures high absorption of solar radiation and low emission of thermal radiation. When the collector temperature becomes elevated >167F (>75C) the absorber will switch or transition to a higher rate of thermal emission. The net result is that the collector will operate at a reduced temperature as the absorber will be rejecting excess thermal radiation. The ThermProtect switching absorber limits the maximum or stagnation temperature of the collector 293F (145C). A meander-shaped copper pipe, through which the heat transfer medium flows, is permanently embedded into the absorber. The heat transfer medium channels the absorber heat through the copper pipe. The absorber is encased in a highly insulated collector housing, which minimizes collector heat losses. The high quality thermal insulation provides temperature stability and is free from gas emissions. The cover consists of a solar glass panel with a very low iron content, thereby reducing reflection losses. The tempered solar glass is 3.2 mm thick, making it very resistant to weather influences. The glass is set into the collector frame with a continuous profiled seal, preventing water from penetrating into the collector. This ensures a long and reliable service life for all internal components. The collector housing consists of a one-piece non-coated aluminum frame into which the solar glass is permanently sealed. Up to twelve collectors can be joined quickly and easily to form a single collector array. For this, the standard equipment includes flexible connection pipes, sealed with O-rings (see flexible interconnection pipes picture). A connection kit with clamping ring fittings enables the collector array to be quickly connected to the pipes of the solar circuit. The collector temperature sensor is installed in the solar circuit flow using a sensor well set.

Product Information Flow Rate in the Collector Array

All Vitosol collectors have a minimum required flow rate (low flow) and maximum flow rate (high flow). The collectors must operate within this range and the system designer must choose a flow rate based on the specific parameters of the system. At the same collector output, a higher flow rate means a lower T or temperature spread across the collector array. Inversely a lower flow rate will have a higher T or temperature spread across the collector array. When the T or temperature spread across the collector array becomes too large, the efficiency of the collectors will also decrease.

Operating modes: Low flow operation Operation with flow rates up to approx. 0.014 USG/min/ft2

0.010 - 0.0143 USG/min/ft2 (25 - 35 L/h/m2)

High flow operation Operation with flow rates greater than 0.014 USG/min/ft2

0.0143 - 0.0245 USG/min/ft2 (35 - 60 L/h/m2)

For larger solar installations, high flow is usually not recommended as this results in bigger pumps and larger pipe sizes. Typically low flow would be used as the decreased flow requirements result in smaller pumps which would use less energy, and small pipe sizes, reducing the overall installation and operating cost for the system.

Flow Velocity

To minimize the pressure drop through the solar thermal system pipework, the flow velocity in the pipe should not exceed 3.3 ft/s (1 m/s). We recommend flow velocities of between 1.3 and 2.3 ft/s (0.4 and 0.7 m/s). At these flow velocities, a pressure drop of between 0.12 and 0.3 w.c. (1 and 2.5 mbar) /m pipe length will result. For the installation of collectors, we recommend sizing the pipes as for a normal heating system according to flow rate and velocity.

Note: A higher flow velocity results in a higher pressure drop and potentially could erode the walls of the pipework. If the flow velocity is too low, the system will not capture or move the air trapped in the system.

Any residual air that has collected at the collector must be routed downwards through the solar return line to the air vent in the solar divicon. This will have to be manually vented.
