Gamme plus heating storage tank without steel exchanger 500 litres

Main features

• Robust construction: steel body with 100 mm recycled polyester insulation (λ = 0.035 W/mK), white skai exterior.
• Versatile installation: main tappings arranged at 100°, facilitating corner installation.
• Efficient stratification: integrated deflectors for optimum thermal stratification, minimizing energy losses.
• Energy compatibility: steel heat exchanger (SE models) in the lower section, ideal for one or two energy sources.
• Safety and performance: maximum pressure of 3 bar (storage tank) and 12 bar (exchanger), maximum temperature of 99°C (storage tank) and 110°C (exchanger).

Optimized thermal stratification thanks to deflectors

Stratification is particularly effective thanks to the deflectors positioned on the inlets, which deflect the flow by making the inlet less direct and more diffuse, avoiding turbulence and mixing that disrupt thermal stratification
Sampling crosses allow water to be drawn from the highest, and therefore hottest, points.

In a nutshell:

Thermal stratification is essential in a storage tank, as it enables layers of water to be maintained at different temperatures without mixing. This optimizes the use of stored energy: the hottest water remains available at the top of the tank for immediate needs (such as heating or domestic hot water), while the coldest water remains at the bottom, ready to be reheated.

Here's why baffles play an important role:

• Reducing turbulence: Without a deflector, water entering the tank creates a direct jet that disrupts the established thermal layers. Turbulence leads to temperature mixing, which reduces system efficiency.
• Diffused water entry: Deflectors direct and slow the incoming flow, allowing the water to gradually integrate into the equivalent temperature layer. This preserves stratification.
• Greater energy efficiency: Good stratification means that heat is used where it's needed, reducing energy consumption to heat the entire body of water unnecessarily.

In short, deflectors increase overall storage tank performance by enabling intelligent thermal storage, with fewer losses and greater system responsiveness.
