Solar pump station Nordic Tec Two-way 1"

Nordic Tec Solar Pump Station - Application

Nordic Tec Solar Pump Station is used in solar installations and systems, typically intended for domestic hot water heating and supporting building heating systems. Thanks to integrated elements such as shut-off valves, safety group with safety valve, or flow meter, it enables efficient and safe operation of the entire solar system.

The pumping station ensures optimal circulation of the heat transfer fluid between solar collectors and the hot water storage tank (simply the DHW tank), which translates into efficient use of solar energy and savings in conventional energy consumption. The solar station, gathering all these elements together, simply saves time and space in the boiler room.

Air Separator in the Solar Station

• ✅ Nordic Tec Solar Station features an air separator

The air separator in the solar pump station plays a crucial role in ensuring trouble-free and efficient operation of the entire installation. Its task is to remove air bubbles and gases dissolved in the heat transfer fluid, which could cause circulation disturbances, noise, and over time, reduce system efficiency. Thanks to the air separator, the circulation pump operates more stably and longer, wearing out more slowly (which translates to lower operating costs). In Nordic Tec solar pumping stations, the air separator is located on the left side, red circuit.

Solar Pumping Station with Rotameter Included

• ✅ Our brand's solar pumping stations include a rotameter with a scale up to 38.0 l/min

The rotameter in the solar station is designed to measure and control the flow of the heat transfer fluid in the circuit between the solar collectors and the hot water storage tank. Thanks to it, the installer or user can easily check whether the flow in the system is correct, uninterrupted, and possibly adjust its value to the requirements of the solar heating system. Maintaining proper flow is crucial for efficient solar energy harvesting, preventing collector overheating, and ensuring uniform operation of the installation. Rotameter thus enables not only monitoring but also regulation of the solar system's operating parameters, which translates into its longevity and maximum efficiency. The rotameter is factory-included in this solar station offer.

Rotameters are also found in other devices (typically in underfloor distribution manifolds), but it should be remembered that only specially adapted rotameters, including in shape, are mounted in solar stations.

Two-Way Solar Pump Station - Nordic Tec - Summary

The solar pump station from this offer is a two-way station (also called dual-circuit). This means a hydraulic set designed for solar installations, which has two circuits for the heat transfer fluid – one incoming from the solar collectors and one outgoing towards the hot water storage tank. In this case, there are no mixing points or mixing valves that could connect these two paths.

Dual-circuit solar station in practice:

• is a standard solution in most solar systems, as two separate circuits are the essence of this system
• typically consists of two shut-off valves, a place for the circulation pump, rotameter, safety valve, pressure gauge, and air separator

Unlike unidirectional (single-circuit) stations, which are used in atypical solutions or extensive installations, the two-way station is most commonly chosen for domestic solar systems, providing full control and safety of system operation.

Nordic Tec Solar Station with Safety Group

• ✅ The product also includes a safety group with a safety valve

The safety group in the solar station serves to protect the system against sudden excessive pressure and temperature increases, which may occur during the operation of solar collectors under certain conditions. It consists of key elements:

• safety valve – a basic element that automatically discharges excess heat transfer fluid when the pressure in the system exceeds the allowable value (in this case 3 bar),
• pressure gauge – (or manameter) allows constant monitoring of pressure in the installation; it is a purely control tool, sometimes (inaccurately) called a pressure meter
• air vent – removes air and gases generated in the circuit, preventing airlocks and disturbances in pump operation.

Thanks to the safety group, the solar system operates stably and is protected against damage caused by overheating or excessive pressure. It is an essential element that ensures the longevity of the installation and the safety of its users.
