Separate Pressurized Active Closed Loop Solar Hot

A 50/50 propylene glycol and water mixture from the collectors through a coil of pipe in the solar tank, and then is pumped back through the collectors. The potable water is warmed by heat transfer through contact with the pipe. These systems are pretty much the only choice in very cold climates. When there is not enough energy for sun, an electrical or gas back up element will be automatically switched on by controller. Feature: 1.Simple Installation, No Maintenance, Effective operation. 2.Easy Retrofitting To Existing systems. 3.Suitable for single and multiple solar heating Application systems. 4.Preferred option for extremely cold areas and questionable water quality. 5.Incoming potable water is routed to the solar storage tank. 6.SUS304 Stainless Steel Storage Tank With Electrical or gas Back Up. 7.Double-walled Copper Coil heat exchangers in storage tank prevent contamination of household water. Systems Specifications: Model Tank Capacity Heat pipe or U Pipe Collector Work Station Φ58X1800 No. SHCLS150S 150L Φ58X1800 15(1 collector for 15 tubes) A circulating unit system that gather controller and pump station SHCLS200S 200L Φ58X1800 20(1 collector for 20 tubes) SHCLS300S 300L Φ58X1800 15X2 (2 collector for 15 tubes) SHCLS400S 400L Φ58X1800 20X2 (2 collector for 20 tubes) SHCLS500S 500L Φ58X1800 15X2+20X1 (2 collector for 15 tubes, and 1 collector for 20 tubes) For the separate system, there are three types for you to choose: 1. Open loop systems without copper coil inside the tank 2. Closed loop system with single copper coil inside the tank 3. Colosed loop sysytem with double copper coil inside the tank If you are interested in any one,please contact me freely.
