Freon heat exchanger

The Ba-68-50 freon-water heat exchanger is part of the Ba-68-F (freon) series and is one of the larger plate heat exchangers used for gases or refrigerants planned. With a surface area of ​​approximately 3.40 square meters, it works great with heat pumps or systems that use R410A, R32, R290, R404 and other refrigerants.

The default configuration of the 50 plate Ba-68-50-F heat exchanger is a unit without accessories. However, if you want to improve its performance, you can also order heat exchanger insulation. This is a very good solution to provide additional protection for the plate heat exchanger and to increase the capacity.

Main features:

• Number of discs: 50 discs
• Connections
  • Gas side: 7/8" tube (φ22)
  • Liquid side (heat absorption side): 1"
• Heat exchange surface: 3.40 m²

• Estimated heat pump / unit / air conditioning power: 22-35 kW
• Operating pressure on the gas side: up to 45 bar
• Heat exchanger insulation is an optional accessory; can be purchased with or without insulation.

The resistance of refrigerant heat exchangers up to a pressure of 4.5 MPa is a fundamental feature that distinguishes them from traditional liquid-liquid heat exchangers.

Heat exchanger R134a-water and R32-water - what other heat pump refrigerants can the Nordic Tec Ba-68-50-F handle?

Currently, the Ba-68-50-F heat exchanger is mainly used as an R134a condenser - that is, an R134a-water heat exchanger. However, most refrigerants and F-gas behave similarly in a heat pump system - of course they differ in their environmental impact and components - some generate slightly higher pressure (such as R32), others are more extensive. Nevertheless, their function is similar - this means that if you are looking for a condenser for a heat pump, but use a refrigerant other than R134a, there will be no problem, you can safely use our heat exchanger.

What refrigerants can be used with Nordic Tec gas-water heat exchangers?

The gas-water heat exchangers in our offer are certified up to 45 bar. This means that practically all available refrigerants can be used within the heat pump's operating range of 65°C. Some examples:

• R134a - an older refrigerant, gradually phased out, but still present in many heat pumps.
• R410a - for a long time it was considered one of the main "freons".
• R407c - a very common refrigerant in air conditioning systems.
• R290 - simply propane, which is also popular in many European countries.
• R32 - arguably the latest trend, a refrigerant that is the most effective, efficient and environmentally friendly.

More refrigerants are of course available, especially considering the trend of converting air conditioners to heat pumps. The fact that a specific refrigerant is not mentioned does not mean that Nordic Tec gas-water heat exchangers cannot handle it. They will not differ significantly from the types mentioned above.
