Ferroli ECOUNIT HP 500-1C DHW Storage Tank

The Ferroli ECOUNIT HP 500-1C DHW cylinder, reference GRM841AA, is designed to provide high performance in the production of domestic hot water (DHW) for industrial and residential applications with high demand. With a capacity of 442 litres and robust construction from high-quality vitrified steel, this cylinder is ideal for indoor installations, offering an efficient and durable solution for generating hot water via heating systems.

High-quality materials and durable vitrification:

The body of the ECOUNIT HP 500-1C is made from vitrified steel according to the DIN 4753 standard, a process that ensures corrosion resistance and a long service life for the cylinder. The vitrification treatment is carried out at 860°C, guaranteeing durable and effective protection against corrosion, even under demanding daily use conditions. This internal coating protects the steel and ensures that the domestic hot water remains in hygienic and safe conditions.

High-efficiency coil:

The cylinder features an internal coil with a large heat exchange surface, with an area of 5.5 m² and a length of 55.2 metres, designed to maximise heat transfer and ensure rapid recovery of hot water. This makes it an efficient choice for applications requiring a continuous supply of DHW, such as in large homes, commercial buildings, or industrial facilities.

With heating water at 80°C, the exchanged power reaches 61 kW, allowing a flow rate of 1,500 litres per hour, while with water at 60°C, the exchanged power is 27.5 kW and the DHW flow rate reaches 676 litres per hour. These high levels of exchange ensure the system can meet large hot water demands in a short time. The hot water preparation time at 80°C is only 14 minutes, and at 60°C, 31 minutes, ensuring rapid availability of DHW.

Integrated electric resistance and temperature control:

The ECOUNIT HP 500-1C includes a 2,000 W electric resistance as standard, adding flexibility to the system by allowing water heating when insufficient heat is available from the main heating system. This feature is especially useful in applications where heat supply may be intermittent or when additional backup for DHW generation is desired.

The cylinder also comes equipped with a thermometer to accurately monitor the water temperature, facilitating system control and ensuring efficient energy use.

Magnesium anode and anti-corrosion protection:

For enhanced cylinder protection, the magnesium anode is included as standard. This essential component acts as a protective barrier, sacrificing itself to prevent corrosion of the cylinder's internal walls, ensuring greater equipment durability. Thanks to this protection system, the ECOUNIT HP 500-1C requires less maintenance and guarantees a long service life.

Installation and versatility:

The Ferroli ECOUNIT HP 500-1C is designed for vertical installation indoors, optimising the use of available space in machine rooms. Additionally, it features a DHW recirculation inlet, allowing the hot water to remain in constant circulation to prevent temperature loss in the pipes, ensuring an immediate supply of DHW without waiting.

This model is prepared to work with a maximum pressure of 8 bar and a maximum water temperature of 95°C, ensuring safe and efficient operation in high-demand systems. Its robust design and capacity to handle large flow rates make it ideal for large residential buildings, hotels, hospitals, or any installation with high hot water consumption.
