What is a Brazed Plate Heat Exchanger?
MIT Brazed Plate Heat Exchangers (BPE) are used in both cooling and heating applications. BPE’s can be used as evaporators or condensers in certain applications like refrigerant cycles.
Capacity and connections can be adjusted as desired for specific applications. MIT Brazed Plate Heat Exchangers have a compact design for confined space requirements.
The Flow Arrangement of a Brazed Plate Heat Exchanger
MIT Brazed Plate Heat Exchangers can be designed with plates having different heat transfer characteristics.
Brazed Plate heat exchangers are high performance components and provide a high level of efficiency combined with compact dimensions and low weight.
- Water glycol (coolants)
- HFC operating fluids
- The quantity of particles in suspension should be less than 10 mg/l.
- Particle size < 0.6 mm. (spherical).
- Thread-like particles cause a rapid rise in pressure drops.
50°F to 437°F (10° to 225°C)(freezing point and boiling point must be taken into consideration!)
- max. 49 psi (3 bar) (static) up to 257°F (125°C)
- max. 435 psi (30 bar) (static) up to 437°F (225°C)
- test pressure: 650 psi
The following limits refer to a pH value of 7
