Heat exchangers / condensers
Glass / SiC heat exchanger – visual process control – excellent heat transfer
Heat exchangers are mainly used in vacuum distillation systems for cooling and condensation in the absorption and rectification processes in chemical plants. Glass heat exchangers enable visual process control during scale-up and production and processing of multiple (acidic) chemical substances. We offer glass spiral type heat exchangers and shell & tube type heat exchangers. These are often operated in combination with a secondary condenser for additional vapor condensation.
The glass spiral heat exchangers can be operated in parallel to form large heat exchange areas for higher condensation performances and larger reactors systems in pilot plants. They feature easy cleaning and operation of cooling media at up to 3 bar pressure.
Shell and tube type heat exchangers are used in combination with packed rectification columns as reflux condenser on larger systems. Buchi offers full glass and glass / silicon carbide (SiC) type heat exchangers with a 0.6 to 23m2 heat exchange area. SiC heat exchangers feature excellent thermal transfer, thus reducing the requested heat exchange area compared to full glass types which can reduce the requested space for the complete system. The optional safety chamber enables easy leakage examination and increases the operation pressures of the cooling media to 6 bar.
