CORDIVARI VOLANO TERMICO PDC PENSILE 50 buffer tank for heat pumps and cooling systems
CORDIVARI VOLANO TERMICO PDC PENSILE 50 is a wall-mounted thermal buffer tank designed for heat-pump heating and cooling systems. CORDIVARI describes this range as hot/cold inertia tanks with two main functions: hydraulic separation and thermal buffering. Hydraulic separation makes the heat-pump flow independent from the terminal-system flow, while the buffer function helps reduce heat-pump cycling.
Although the model designation is “50”, the actual capacity specified by CORDIVARI is 51 litres. The tank is designed for wall installation, making it particularly suitable where floor space is limited.
The tank is manufactured from carbon steel. It is insulated with high-performance rigid polyurethane foam and finished with a grey PVC outer covering. Energy-efficiency class is B, while heat loss is 38.92 W.
The operating temperature range is -10 to +95 °C, allowing use in both heating and cooling applications. Maximum operating pressure is 4 bar.
The main system connections are 1 1/4", while safety-valve and drain connections are 1". Overall diameter is 343 mm, height 1008 mm, and weight 16 kg.
