CSP Holding Group is one of the reliable factory and suppler for solar vacuum tube、heat pipe solar vacuum tube、heat pipe solar collector、solar water heater and parts for SWH over 12 years,we have the world class full range of automatic lines for solar thermal products from glass tube to solar water heater .

Our heat pipe solar collector is manufacturing based on top quality standard,it can be worked -50 degree,also,the stagnation can reach more than 200 degree.The collector range is from 10 – 30 tubes or by order.Right now,we are producing over 10000 units per month which can make sure the fast delivery .Due to we are producing solar vacuum tube,heat pipe by our-self ,so the quality is strictly control-ed by our company.

Right now,our heat pipe collector have exported to USA,Germany,Italy,India,Mexico,South Africa,Middle East and so on.Our target is to be the number one supplier in the world for the solar collector and we will do our best to leading the quality and service in the market.


The evacuated tube solar collector works by absorbing solar energy in the form of UV rays and converting it into thermal energy. An evacuated tube solar collector contains a number of evacuated tubes (we offer from 10 and 30).

A solar collector is not really a solar water heater. A solar water heater is a system which may include a tank, pump, controller and solar collector panel. A solar collector is that part of the system which absorbs the sun’s energy and converts it into heat.
