Passive Solar Collectors PHS Series

At North American Solar Solutions, our high pressure stand alone module is a new type of solar water heater "Specially made for the Mild and Northern Climates" which adopts advanced all glass vacuum tube technology. A thermo siphon system relies on warm water rising, a phenomenon known as natural convection, to circulate water through the solar absorber and to the tank. In this type of installation, the tank must be located above the absorber tubes/panel. As water in the absorber heats, it becomes lighter and naturally rises into the tank above. Meanwhile, cooler water in the tank flows downwards into the absorber, thus causing circulation throughout the system.

The available size of the tank ranges from 90L to 350L. These solar collectors can also be used for commercial, industrial and household applications. The collectors are manufactured from food-grade stainless steel and the inner 15 meter copper coil is used as the heat exchanger. The frame is completely manufactured from extruded aluminum, durable & strong.
