Ferroli ECOUNIT HP 500-1C ACS Accumulator

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

High-quality materials and durable vitrification:

The body of the ECOUNIT HP 500-1C is made of vitrified steel according to the DIN 4753 standard, a process that ensures resistance to corrosion and a long service life of the accumulator. The vitrification treatment is carried out at 860°C, which guarantees long-lasting 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 hygienic and safe.

High-efficiency coil:

The accumulator features a large surface internal coil, with an area of 5.5 m² and a length of 55.2 meters, designed to maximize heat transfer and ensure rapid recovery of hot water. This makes it an efficient option for applications that require a continuous supply of DHW, such as 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 liters per hour, while with water at 60°C, the exchanged power is 27.5 kW and the DHW flow reaches 676 liters per hour. These high exchange levels ensure that the system can meet large hot water demands in a short time. The preparation time for hot water at 80°C is only 14 minutes, and at 60°C, it is 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, allowing the water to be heated when there is insufficient heat from the main heating system. This feature is especially useful in applications where the heat supply may be intermittent or when additional backup for DHW generation is desired.

The accumulator also comes equipped with a thermometer that allows precise monitoring of the water temperature, facilitating system control and ensuring efficient energy use.

Magnesium anode and corrosion protection:

For greater protection of the accumulator, the magnesium anode is included as standard. This essential component acts as a protective barrier, sacrificing itself to prevent corrosion on the internal walls of the accumulator, ensuring greater durability of the equipment. 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, optimizing the use of available space in machine rooms. Additionally, it features a DHW recirculation connection, which allows maintaining hot water in constant circulation to prevent temperature losses in the pipes, ensuring immediate DHW supply 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 ability to handle large flow rates make it ideal for large residential buildings, hotels, hospitals, or any installation with high hot water consumption.
