2. Dec 04 Thermosiphon France 2 Introduction Collectors Thermo siphon systemsMultiple Thermo siphon systems All Solahart collectors are Harf type collectors 4 connections on each corner Maximum of 8 collectors parallel Each collector has the same temperature rise over the collector. Discription of Solahart Collector

3. Dec 04 Thermosiphon France 3 Two different absorbers possible : Kf Collector : Multiflow absorber With 35 chanels. Steel absorber with nickel corosion protection and black chrome selective surface. Speccialy for Thermosiphon systems. Bt Collector : absorber with 13 copper tubes and a copper absorber plate with Bleu sputter selective surface. Specially for pumped systems Introduction Collectors Thermo siphon systemsMultiple Thermo siphon systems
