Nexus PAWT-800L LE1 Stainless Steel Solar Thermal Water Heater 800L
The Nexus PAWT-L LE1 is a stainless steel solar thermal water heater for domestic hot water production in professional solar thermal installations. The vessel is designed for installers who need a durable storage cylinder with one integrated corrugated solar heat exchanger.
The AISI 316L stainless steel solar coil transfers heat from the solar thermal circuit to the stored water. This makes the PAWT-L LE1 suitable for solar collectors, technical rooms and projects where reliable sanitary hot water storage is required.
With sensor pockets, an electric heating element connection and a frosted-metal outer casing, the PAWT-L LE1 is practical to install, control and maintain in professional HVAC and sanitary hot water systems.
