Evacuated Tube Collector
Evacuated Tube Collector
Evacuated Tube Collector We offer our clients an exclusive range of Evacuated Tube Collector that is provided with multiple evacuated glass tubes. These glass tubes heats up solar absorbers that in turn heats up the solar working fluid (water or an antifreeze mix - typically propylene glycol) that is used to heat domestic hot water or for hydraulic space heating. The vacuum within the evacuated tubes reduce convection and conduction heat losses, allowing them to reach higher temperatures as compared to the most flat-plate collectors. The evacuated tubes draw their energy from the available light rather than outside temperature. This makes our range of Evacuated Tube Collector to perform well in colder conditions. In warmer climates it requires special system design to avoid or mitigate overheating conditions though some have built in temperature limitation.
