A large heat exchanger with a surface area exceeding 4 square meters, precise plate surface of 4.2 m². The exchanger features large connections and low hydraulic resistances. It can handle large, even large-scale buildings, in cooperation with large boilers, boiler cascades, or district heating systems.

The Ba-60-70 heat exchanger is also commonly used for separating heat pumps from central heating and domestic hot water systems. These can be monoblock heat pumps on glycol (thus separated from the heating system), but also split pumps separated, for example, from open-loop systems.

Heat exchanger for heat pumps and more | Ba-60-70

Applications of this heat exchanger can be different - generally Ba-60-70 is rather a bigger unit for more demanding or large systems:

  • The exchanger supports installations with both monoblock and split-type heat pumps - it can operate with glycol. In such installations, the exchanger acts as a connector between the part of the system connected to the heat pump filled with glycol (-> less commonly with water) and the other part of the system, such as the heating circuit. Depending on the supply temperatures provided by the heat pump, this exchanger can handle units from 15 kW (-for low-temperature systems around 30°C) up to 30-32 kW in standard systems with temperatures around 50°C (for systems with glycol). Connecting the heat pump circuit and the heating circuit is the most common (at least as noted by us) application of this plate heat exchanger - Ba-60-70 by NORDIC TEC ;
  • Connecting closed-loop (-> sealed system) and open-loop systems of large boiler rooms in heating installations (or domestic hot water) in large buildings, larger in terms of area - hotels, guesthouses, production halls, warehouses, shopping centers ;
  • Heat exchanger for receiving heat from district heating networks (DHN) in large-scale buildings ;
  • Heat exchanger for air heaters - used in heating halls and warehouses. With glycol-filled heating systems, it is able to heat air heaters supplied by a boiler (supply temperature around 50-60°C) even up to 150-160 kW, and if filled with water, up to 180 kW ;
  • Industrial refrigeration - the heat exchanger serves as an industrial cooler for cooling oil or other media

Plate heat exchanger 70 with thermal insulation - Ba-60-70

  • The Ba-60-70 heat exchanger can be optionally purchased with PHE thermal insulation
  • The thermal insulation of the exchanger is made of black EPP foam, a material with excellent insulation properties.
  • Thermal insulation for plate heat exchangers is used in heating installations; in refrigeration applications, it is mostly unnecessary.
  • Without insulation the heat exchanger releases a portion of thermal energy to the surroundings in the boiler room, resulting in heat losses. Due to the relatively large external surface area of this model, insulation is more critical than with smaller heat exchangers. It is estimated that a plate heat exchanger without insulation can lose even several to several tens of percent of thermal energy (of course, a higher heat loss rate is possible only during certain stages of heating the installation).

The heat exchanger for a monoblock heat pump with a capacity of 30 kW or a split heat pump with a capacity of 32 kW

The Ba-60-70 heat exchanger is designed for use with monoblock heat pumps ranging from 15 to 30 kW in most configurations. In some setups it may efficiently operate even with monoblocks up to 32 kW, especially those operating with water (--> it's worth noting that the presence of glycol in the system slightly reduces heat transfer, meaning the unit's capacity that can be handled decreases). Similarly - when separating split heat pumps (operating with water), the capacity can be up to 32 kW.

However, it's essential to remember that this range (15 kW - 25 kW - 30 kW) doesn't imply arbitrary selection within its bounds. It is strictly dependent on the operating temperature of the heating system. In systems where the heat pump is only required to provide the lowest possible temperature, i.e., around 30-35°C, the heat source itself will operate at maximum efficiency, but a larger heat exchanger will be required for this purpose. The upper limit applies to systems with traditional supply temperatures of around 50°C.

In general the Ba-60-70 plate heat exchanger is considered a large exchanger capable of working with large heat pump units and servicing large buildings.

Why is a heat pump separated from the central heating system by a heat exchanger?

There can be many reasons for separating heat pumps - typically in the case of monoblock pumps, it is for safety reasons, as the investor chooses to fill the device circuit with glycol (antifreeze). Of course we refer here to the areas where the climat creates such a danger. In such cases we want to separate the glycol from the household system, which operates on water ( -> as it is not recommended to fill the household heating system with glycol).

However there may be another reason - which also applies to split heat pumps, which operate on water. There may be a need to separate them from an older system in the household, which may be an open-loop system - while the pumps require operation in a closed-loop, pressurized, sealed system. Such a need often arises in older houses or buildings, especially when the investor has another heat source operating in an open-loop system, such as a fireplace with a water jacket or a wood boiler.


Please note that the Ba-60-70 heat exchanger is intended for heat pumps but designed to work with liquid media.
