Our low pressure collector is designed for large volume heating. The internal manifold and external body is constructed from 316 stainless steel. The water flows from the manifold and directly into the glass tube, where the tube heats the water directly. Sunrise Solar have various collector sizing in this model and start at 48 tubes and go up to 60 tubes per manifold.
