Mzuri Sweets Ltd. is a major player in the confectionery industry in Kenya. The company manufactures high quality gumballs, bubblegum, candy and lollipops, all under the signature brand, Mr. Berry’s. The company’s commitment towards quality has enabled it to thrive in a market, previously dominated by both foreign and local confectionery multinationals.
In light of the pandemic-induced lockdown, Thermax helped Mzuri Sweets prepare for a proper shutdown and safe restart. Thermax’s technical intervention ensured continuous operation and productivity at the plant amidst the crisis.
Thermax’s chillers cooling the plant floors
Mzuri Sweets is known for deploying advanced technologies in its manufacturing plant to achieve the best quality production. In line with its commitment towards quality, the company had sought Thermax’s cooling solutions for comfort cooling its premises. Hence, Thermax had commissioned a double effect steam fired vapour absorption chiller at the manufacturing facility in early 2016. The chiller’s performance has been good ever since the commissioning and the company was immensely satisfied with its operation.
Temporary lockdown in response to government guidelines
As the COVID-19 pandemic swept across the globe, the Kenyan government announced a 20-day lockdown across the country. The sudden announcement presented Mzuri Sweets with a significant operational challenge. The company was looking for ways to properly shut down the manufacturing plant – all the while preparing for a quick rebound after the 20 days of inactivity. The immediate crisis pushed the plant operators to quickly find ways of sustaining their operations while mitigating operational risks.
Service via ROSS: Re-imaging chiller monitoring and control
In order to ensure a smooth startup and avoid any mishaps in the future, the plant operator contacted Thermax for proper shutdown of the chiller. The conventional way of shutting down the chiller would have been to visit the site, monitor the chiller parameters, and implement the shutdown procedures.
With travel restrictions and social distancing measures in place, visiting the plant was out of the question. This is when Thermax’s cloud-based chiller monitoring system – ROSS (Remote Online Service Support) proved useful in controlling the chiller while being far away from the site. The capability to remotely monitor the parameters, status, and usage of the chiller ultimately ensured a smooth shutdown and startup at Mzuri Sweets.
Implementing chiller shutdown procedures
After analysing the operational conditions of the chiller, Thermax’s technical service expert communicated standardised shutdown procedures to the plant operator at Mzuri Sweets.
- Complete dilution of the chiller to bring LiBr to room temperature
- Isolation of steam inlet and outlet valves to ensure maximum productivity once the plant operations are restarted
- Breaking chiller vacuum
- Shutdown of diaphragm valves
ROSS’s assistance in reviving plant operations
After the short-term inactivity, when the plant operations at Mzuri Sweets resumed, our service expert intervened again for a smooth rebound. As the operations began to normalise, Thermax’s assistance towards achieving pre-shutdown productivity at Mzuri Sweets included the following recommendations:
- Maintenance of inlet cooling water temperature to prevent high scaling and generation of non-condensable gases
- Regular scheduling cooling tower service
- Periodical cleaning of water strainers
Shutdown and revival service support benefits
By clearly analysing, communicating, and enforcing the best shutdown and revival practices, Thermax’s service enabled Mzuri Sweets to enjoy the following benefits:
- Access to the same expertise as on-site services
- Decreased amount of downtime
- No loss of production
- Achieve pre-lockdown productivity when the operations resumed
- Operational enhancement by means of dilution and maintenance
- Increased chiller reliability
Combining chiller monitoring technology and service excellence, Thermax has ensured operational continuity at Mzuri Sweets. The thorough analysis and great co-ordination between the teams from Thermax and Mzuri kept the plant up and running, despite the unavailability of a chiller expert on premises. By leveraging ROSS, Thermax assures excellent service support for continued productivity in industries even in situations of utmost uncertainty.
