B25TNx40/1P-SC-M 2x22U(20) + 2x1"&22U Brazed Plate Heat Exchanger Swep
The compact brazed Swep heat exchanger basically consists of a package of corrugated plates with closing sets of plates at the front and back. The set of closing plates consists of sealing plates, sealing rings and lid plates. Various types of connections are used to connect Swep to the client's system. In the process of vacuum soldering, a solder joint is formed at each point of contact of the base material with the solder. The design of the plates is such that it creates two separate channels or circuits in the Swep heat exchanger.
The standard location of the connection holes is on the front side of the Swep heat exchanger. The connection type can be customized according to the specific requirements of the local market and the specific application.
The closing plates are designed to hermetically separate the space between the lid plate and the outermost of the corrugated plates forming channels. The closing plates are also called the starting and ending plates. In some Swep models, the closing plates are integrated with the cover plates. The number of cover plates depends on the Swep heat exchanger model, pressure range, etc.
Some Swep heat exchangers have sealing rings to separate the space between the channel plate and the cover plate, others have a design in which the sealing rings are integrated with the cover plate and the first/last channel plate. The figure above shows the standard configuration of the plate package, but other options are possible. Note also that the directions of the so-called "Christmas trees" change when moving from each plate to the next.
- Plate materials: AISI 316, Mo-steel
- Temperature: from 195 to + 350 °C
- Power: up to 250 kW
- Types of solder: copper (99.9%), nickel alloys
Plate design:
- symmetrical elevation angles at obtuse and acute angles
- double plates for processes where mixing of working media is unacceptable
Most of the Swep heat exchangers are type B heat exchangers. The main structural material for type B is AISI 316 stainless steel, and pure copper is used as solder. Typically, the pressure range (i.e. maximum operating pressure) for Swep heat exchangers of this type is up to 31 bar (450 psi) at temperatures up to 185°C. This is a standard type of Swep heat exchangers
B10 — An efficient heat exchanger used at a wide power range that can be quickly and easily adapted to multiple applications. Its compact size, versatility and excellent thermal conductivity make it an ideal heat exchanger for both single-phase and refrigerant devices.
The B12 heat exchanger with a large port is a compact heat transfer device for use in high flow conditions. It is available with different plate configurations for different heating capacities with a wide range of viscosity and density of the liquid. The B12 is an excellent choice for steam and air dryers that have high equipment requirements. It can be used as a steam cooler in air conditioning systems and as a heat exchanger for cooling the intake CO2 gas in cooling systems.
B25 — An efficient heat exchanger used with a wide power range that can be quickly and easily adapted to numerous systems. Due to its versatility and excellent heat transfer, the product is ideally suited for use in refrigeration installations where high equipment requirements are imposed, as well as as a capacitor in two-phase devices.
B35 It is ideal for applications in the fields of district heating, heat recovery, combined power and heat generation and engine and transmission oil cooling. It is ideal for efficient heat transfer with low pressure drop in systems with 2-inch pipes and a water flow of 27 m3/h.
