NIBE EKS 750 Accumulator Tank

Description

NIBE EKS 750 is a high-performance accumulator tank developed for facilities with extensive needs for domestic hot water. With a generous water volume of 740 liters, the tank functions optimally as a pure accumulator in combination with a charge exchanger or heat pump system, while there is the possibility of backup operation via an immersion heater. The design makes it possible to keep the installed power at a balanced level, which effectively limits the property's total power output at times when the need is greatest.

NOTE! Velltra assures that all NIBE products marketed and sold by us are manufactured in Sweden and contain components of the highest quality, specially adapted for the Nordic market and its challenging climate.

Reliable hot water capacity during large peak drains

For properties and commercial environments with recurring peak loads, the NIBE EKS 750 offers a stable operating solution. The tank's volume ensures that large amounts of hot water are available immediately during momentary peaks without overloading the system. The solution provides a smooth and reliable access to hot water in combination with modern heating technology.

Proven corrosion protection and high operational reliability

The accumulator tank is internally equipped with a durable copper corrosion protection, which provides a long service life and high water quality over time. The design is dimensioned for a maximum working pressure of 10 bar and handles temperatures up to 90 °C, making it well suited for varying and demanding operating conditions.

Energy-efficient insulation and easy handling during installation

To minimize heat loss, NIBE EKS 750 is equipped with high-quality, environmentally friendly insulation that keeps energy loss at a very low level. The insulation is completely removable, which facilitates transport through narrow passages, doorways and simplifies placement in technical or substations.

Flexible connections and adaptation for additional electricity

The tank is equipped with ample connection options for smooth integration into both new installations and existing heating systems. It is prepared for the connection of immersion heaters (G50), which provides flexibility to add extra peak heat or safe backup when needed. In addition, there are adapted sockets for thermometers, pressure gauges and thermostats for precise control and monitoring.

Warranty and Swedish quality

Please note that the manufacturer’s full warranty is not applicable for units bought in Sweden and installed outside Sweden.
