Solar receiver--- Parabolic trough receiver (PTR 40/95/4060MM)

PTR 40/95/4060MM, this model is our regular model, it is mainly used for large trough system. It is the most commonly used model in large-scale trough solar power projects.


Solar parabolic trough receiver, also called the evacuated solar receivers, is a key component of the solar process heating (SPH) system, can be used at large scale solar concentrated power station, solar steam generation system. Its thermal and optical performance as well as stability determines the efficiency and economy of the whole system.

Trough solar collector is an efficient linear focusing solar heat collection device, 

which is mainly composed of a transmitter mirror, a collector tube, a support system, 

a tracking system, a transmission system and a control system.  

It has the advantages of mature technology, stable structure and easy control. 

 The mirror rotates with the sunlight, can directly replace the solar energy with heat energy, 

and is widely used in solar solar thermal power generation, industrial steam, heating and cooling, 

seawater desalination, coal-fired boiler replacement, 

oil exploitation, facility agriculture, agricultural and sideline products drying and other fields.
