Nexus 12L solar pre-cooling vessel model STP-12

Nexus 12L solar pre-cooling vessel model STP-12 to protect the solar expansion vessel against high temperatures during collector stagnation.

Nexus solar pre-cooling vessel

This solar pre-cooling vessel protects the membrane of the solar expansion vessel from extreme temperatures that can occur during collector stagnation. The cooler fluid in the vessel helps reduce the temperature of overheated solar fluid before it reaches the expansion vessel.

Key benefits

• Protects the membrane of the solar expansion vessel
• Supports safe operation during stagnation and high temperatures
• For solar thermal and domestic hot water solar systems
