When selecting a model, first ask a specific question: under operating conditions of -40°C to 200°C and a design pressure of 3.0 MPa, can a plate-type structure simultaneously meet the requirements for compact layout and corrosion resistance? For design and selection personnel, this often determines the direction of the heat exchange loop scheme. The BXS-160 brazed stainless steel heat exchanger can serve as one of the benchmarks for comparative evaluation.
Removable plate heat exchangers are easy to disassemble and clean, but rely on gasket sealing, and gaskets have limited compatibility with temperature and media. This model uses a brazing process to connect the plates into an integral unit, eliminating gaskets, and within the range of -40°C to 200°C can reduce maintenance requirements caused by seal aging, with a more compact structure. Its single-unit heat exchange area is 4.5 m², overall dimensions are approximately 620×280×420 mm, and weight is approximately 48 kg, making it suitable for unit layouts with limited space.
Shell-and-tube heat exchangers have wider pressure-bearing capacity and application range, but their heat exchange area per unit volume is usually lower than that of plate-type units. This model has a design pressure of 3.0 MPa, DN50 connections, and plate material options of 304/316L stainless steel, making it suitable for refrigeration, heating, and general industrial heat exchange loops. If the medium is clean and the temperature difference and flow rate match, choosing a compact brazed scheme can reduce footprint and charge volume; if the medium contains particles or is prone to scaling, cleaning conditions still need to be evaluated.
Design and selection personnel should verify item by item based on medium characteristics, pressure, and temperature parameters: confirm the compatibility between the chloride ion content in the medium and the stainless steel grade, check the matching of DN50 connections with the piping, and verify the heat exchange capacity and pressure drop margin according to the 4.5 m² heat exchange area. Arranging the cleaning method and maintenance space during the selection stage helps ensure long-term stable operation of the equipment.
