1. Operation with contaminated or highly viscous fluids. If we consider spiral heat exchangers, this advantage immediately catches the eye. It can be easily explained by the fact that there are no dead areas in the device channels, they are wide enough, even for large particles of solid inclusions. Therefore, the heat transfer surface is virtually not contaminated. In addition, due to the rather high speeds in channels, they will self-clean.
2. Easy and quick access to spiral. The simplicity and convenience of the design means easy access to both sides for overhaul, flushing and inspection. If you compare plate and spiral heat exchangers, at this point you can see their similarity. This is very actual in cases where mechanical cleaning is necessary.
3. Compactness. Spiral heat exchanger in itself has rather modest dimensions. Accordingly, it requires minimum space for its installation and operation. It is also quite convenient to connect it to the supply pipelines and dismantle it for subsequent service.
4. Efficiency. Despite the lack of corrugation and a fairly wide gap between the spirals, the heat transfer coefficient in the spiral heat exchanger remains at a very decent level and may compete with shell and tube ones. This affects the overall dimensions and heat transfer surface area. Indeed, in today’s market, it is one of the key indicators.
5. Material modification. In order to take into account the specifics of the customer’s manufacturing facilities, ensure the correct life, and based on the technical specifications of the spiral heat exchangers, we will choose the most optimal materials. There is a possibility of manufacturing spirals from stainless steels, nickel alloys, titanium.
