Special Features:

1.)Heat pipe ports provide simple plug in installation while still ensuring tight contact with the heat pipes for optimal heat transfer. Thermal heat conduction grease is applied to the heat pipes condenser prior to insertion to further enhance heat transfer. Given the high temperature that the manifold is exposed to, the expansion of the heat pipe condenser and "setting" of the heat conduction paste results in the heat pipe being firmly held in place. This ensures excellent heat transfer for the life of the solar collector. As the heat pipe is extremely reliable and durable, there is no need to ever remove or replace the heat pipe, even if change a solar tube.

2.)The twin header pipes are molded to match the shape of the heat pipe ports in order to maximize contact area. In addition, the heat pipe ports are brazed to the twin header pipes providing a direct metallic connection.

3.)The "contoured" header pipe design produces turbulent water flow enhancing heat transfer.

4.)Available in rear port or end port inlet/outlet configuration.

5.)8mm ID copper temperature sensor ports at both the inlet and outlet that are brazed directly to the header pipe for accurate temperature measurements
