Maintenance and Spares

• No maintenance

• Tubes are carbon steel & solution pumps are standard centrifugal pumps.

Maintenance & Spares

• Vaccum maintenance is critical for functions and system life

• Copper Nicket tubes and hermetic pumps are very costly

• Copper Nickel tubes need replacement periodically and hence repair cost is very high

Life

• Long life of 25 years or more

Life

• Entire equipment life is not more than 15 years

Corrosion is negligible

Corrosion is high

Due to Low corrosion repairs maintenance cost are very low

Due to corrosion tube repairs & replacement is frequent. All tubes are copper or copper nickle tubes. Therefore, tube replacement is very costly

Due to pressurised system; No special care is needed.

Due to vacuum system; special care is needed otherwise plant stops frequently. Also due to tubesheet joints, the vaccum loss is frequent with passage of time. Fault finding is very time consuming.
