In case of applications in geothermics, the water quality of the thermal water must be assured. In the same way, special demands can be expected as a result of the occurring pressure characteristics. In geothermics, work is carried out at a higher pressure level, dependent on the depth of the bore and the quantities to be conveyed.
Typical tasks for SIGMA plate heat exchanger are:
- Cooling and heating of RME
- Cooling and heating of glycerine
- Pre-warming of crude oil
- Heat recovery with RME
- Cooling of water circulation systems
Application : Biodiesel
In applications with biodiesel, the plate heat exchangers are equipped with high-quality seals made from Viton, in order to resist high chemical stressing. The employment of sealed plate heat exchangers is necessary, due to the dirt-accumulation characteristics of heat exchangers, they must be opened for cleaning.
Application : Geothermics
In geothermics, strongly corrosive water from deep rock formations is pumped. This requires the employment of high-quality materials, such as titanium. In the same way, large volume flows are pumped so that equipment types of large sizes are employed (e.g. SIGMA 156; SIGMA 229). In applications in geothermics, it is necessary that the heat exchanger can be opened for cleaning.
