Plate Heat Exchanger NORDIC Ba-60-30 1 1/4" 330kW

The above graph illustrates the heat exchange surface area of the  Ba-60-30 heat exchanger and compares it with other devices from the same series with a different number of plates. The graph allows understanding the relationship --> between the number of plates and the total heat exchange surface area. A single plate of the heat exchanger has an area of 0.060m2. Multiplying this by the number of plates gives us the final surface area - for the Ba-60-30 heat exchanger, it will be 1.80m2. If you need a larger surface area , you can find larger heat exchangers from the Ba-60 series on the graph, which are also available in our offer.
Below, you will read how the surface area of 1.80m2 translates into the practical application of the heat exchanger.

Heat exchanger for monoblock heat pump 12 kW - 14 kW with glycol or water

If you are looking for a heat exchanger for a monoblock heat pump between 10 kW and 14 kW - for a system operating on glycol, then the Ba-60-30 model is very suitable for this range. First of all it is a heat exchanger completely resistant to glycol, making it ideal for monoblock heat pump systems that operate with this medium - but naturally it can work with water too.

Monoblock heat pumps of 12 - 14 kW, when operating on glycol, require approximately 1.8m² of heat exchange surface - assuming it is a high-temperature system (typical for heat pumps) - i.e., operating within 50-55 degrees Celsius. This is a classic power supply model for single-family homes, where most of the heating relies on radiators (which require supply at this temperature - at least in the vast majority of cases). The Ba-60-30 heat exchanger has exactly 1.8m² of surface area. It can handle slightly larger heat pump capacities, in kW - in cases where the system operates on water rather than on antifreeze fluid ( which always somewhat hinders heat transfer).

The sizing of a plate heat exchanger for a heat pump for a low-temperature system is different - for example, for a house based on underfloor heating, where all the heat goes directly to the underfloor distribution manifold. The operating cost of such a system is usually lower, and the power consumption by the heat pump is lower - but at low supply temperatures around 30-35°C - a much larger plate area is needed to accommodate a given heat pump model (even twice the sizing factor may be required for the heat exchanger selection). In this case, a heat exchanger with a surface area of 1.8m² will only accommodate heat pumps in the range of 6 kW - 8 kW.

Heat exchanger 5/4" for a 60 kW boiler | Nordic Tec Ba-60-30

The Ba-60-30 heat exchanger with a 5/4" connection is practically universal and is often used for central heating boilers. The upper limit of the boiler power it can reliably handle is 60 kW, sometimes up to 70 kW in certain conditions. Boilers of this size (usually) should not be serviced by 1-inch models, so the Ba-60-30 heat exchanger is equipped with a DN32 5/4" connection - or, if preferred, 1 1/4".

In this case, the 30-plate heat exchanger essentially serves as a connector between a closed (pressurized - suitable for heating installations) and an open system, where an older type of central heating boiler operates - for example, a coal-fired boiler that requires operation in an open system.

However, it can also be the reverse situation - where the heat exchanger will serve a boiler operating in a closed, pressurized system - many newer types of boilers require this - such as gas boilers/condensing boilers. The heat exchanger will then transfer heat to the heating system, which operates in an open system - this is a fairly common situation, for example, when modernizing heating in an old building and adding a modern central heating boiler. In both cases, regardless of the fuel, this model will easily handle central heating boilers of around 60 kW.

It is worth noting that a 5/4" heat exchanger is very suitable for operation in open systems, as it generates much lower hydraulic resistance than models with a 1-inch connection.
