Special structure spiral heat exchanger

Overhead condenser of spiral heat exchanger is very economical.

It comes to overheads such as the distillation column directly-connected,

and support frame and vapor pipe are not required, and construction cost is reduced.

Falling film reboiler of spiral heat exchanger (SHE) forms ideal falling film with multi-spray nozzle.

Falling film reboiler of SHE is optimum for high vacuum operation, because of no boiling point elevation by liquid depth.

Additionally, falling film reboiler of SHE can be installed under column directly without support frame and vapor pipe. This SHE is very compact.

Calandria evaporator of spiral heat exchanger is high-efficient evaporator.

It has down-flow passage to get thermo- siphon circulation.

For steam generator in building humidity, many Calandria evaporators of SHE are operated for space saving.
