Collector systems

SEIDO 1 Our most economical collector, with standard straight absorber in the glass tube, which converts sunlight to free heat energy. Appropriate for the majority of installations.

SEIDO 2 This collector features higher efficiency with direct flow of liquid through each vacuum tube. Can be mounted in any orientation for greater design flexibility.

SEIDO 5 These collectors feature a bent (convex) absorber in the glass tube, which allows the collector to remain active even at low sun in the early morning or late afternoon. Appropriate for select installations.

SEIDO 10 This collector is similar to our Seido 1 style but features smaller diameter and shorter tubes.

BP Series This batch type collector combines Seido 1 evacuated tubes with water storage in one low cost, convenient assembly. Ideal for cabins, workshops and smaller homes.
