Saving 6,210 Litres of fuel by reducing steam consumption for a Beverage Bottle Washer in Thailand

During our survey of a leading beverage plant in Nakhon Ratchasima, Thailand, we observed that the process temperature for Bottle Washer 2 was exceeding the set value of 65°C (149°F) by 3 – 5°C (37.4 – 41°F). This resulted in excess steam consumption. Our recommendation was implemented, reducing the energy consumption of Bottle Washer 2.

PROBLEM

Bottle Washer 2 was experiencing a temperature overshoot of 3 – 5°C (37.4 – 41°F) against the set value of 65°C (149°F). This resulted in excess steam consumption. Additionally, the process temperature was not being monitored.

SOLUTION

Forbes Marshall conducted a detailed survey of the plant and recommendations were implemented. For Bottle Washer 2 we found the temperature control valve was unable to regulate the temperature precisely (to the set value of 65°C / 149°F). We recommended and installed a PID temperature control valve (eVALV). This ensured precise temperature control and reduced Bottle Washer 2 steam consumption.
