Overheating and air pockets in solar systems can lead to malfunctions that must be eliminated by qualified personnel. To counteract these problems, STI uses drain back systems with a simple operating principle. Modern and powerful solar systems reach very high temperatures. The following problems can occur in conventional systems:
- overheated glycol
- high pressures
- steam Strokes
- dirty non-return valves and pumps
- air inclusions
- corrosion by acidic heat transfer medium
The drain bach systems from STI solve these problems and provide lasting protection for the solar systems. They also reduce maintenance costs and ensure safe and gentle operation of the system.
