Sweet success for the chocolate industry

18 September 2014

Temperature control expert improves energy efficiency for leading British confectioner.

By 2020 it is estimated that the global chocolate industry will have increased by around 30%, equating to approximately 4.5 million tonnes of chocolate being consumed every year. With such strong market growth, the industry is making lasting foundations to meet the increasing demands. At the heart of the operation is temperature control; ensuring the finished product is cooled and stored at optimum temperatures to maintain product quality until it reaches the consumer. 

Temperature control specialist, ICS Cool Energy, has developed a solution for a Midlands-based confectioner who was looking to move away from their aging water-cooled chillers and existing system relying upon R22. 

Richard Metcalfe, UK Sales Director at ICS Cool Energy explains: “The existing water-cooled chillers and cooling towers were showing significant signs of failure, consequently resulting in lower production volumes and an inconsistent texture of products. 

“As the company wanted to move away from water-cooled chillers in favour of air-cooled solutions, our engineers recommended two Imperium i-Chillers featuring two highly efficient screw compressors: one of which is fixed speed, and the other is variable speed. This configuration improves performance efficiency when the chillers are running even at part load conditions.”

The Imperium i-Chiller has a variable flow rate to ensure it operation is economical. The new system doesn’t rely on R22 thus eliminating the need to replace any redundant equipment next year when it fails. 

Metcalfe continues, “During the installation, our engineers supplied a rental chiller to support site operations and ensure production levels could be maintained while the new equipment was installed and commissioned”. 

The units are fully controlled with compatible management software and both chillers run at a variable flow rate of 30%, ensuring maximum cost savings and offering system payback of less than two years.
