Stainless steel AISI 316L tank

Thanks to the removable U-tube heaters, solar DHW boilers represent an upgradeable and easy to maintain solution suitable for use with all types of energy.
They have been specifically designed to meet solar domestic hot water production and storage needs (collection and backup) in the service and manufacturing sectors

The lower exchanger (solar U-tube heater) heats the device from a renewable energy source (solar,heat pump, etc.). If necessary, a second exchanger positioned in the top section (primary U-tube heater) can provide additional energy via a heat generator.

Designed in accordance with CODAP and incorporating more than 60 years of experience in the field of storage tank production, these cylinders meet the demands of EN13445 and CE standards.

Advantages

• Multi-purpose:
– Heating possible from any energy source.
– Simultaneous feeding of multiple consumer circuits.
• Easy to maintain: removable heaters.
• Upgradeable equipment: thermal equipment mounted on manholes can be easily replaced (power or energy changes).
• Significant water storage capacity, to meet peaks in demands.
• Water can be stored at a constant temperature of up to 95°C (depending on the model).
• Particularly suited for use with solar energy recovery systems, heat pumps and solid or gaseous fuel boilers.
• Non-standard versions are available on request.
• Reduced greenhouse gas emissions.
• Multiple nozzles (hydraulic loops, attaching control equipment, regulation and safety accessories).
• Delivered to site with pre-assembled insulation and thermal backup system (can be easily removed if required).
