Star delivered an energy efficient system that ensures plant reliability and future proofs the business
(PRWEB) September 16, 2016
The global leader in the design, development and manufacture of acrylic-based products, Lucite International replaced their old R22 plant at Cassel Works, their largest European site, with a more eco-friendly option.
The new refrigeration plant, design, manufactured and installed by industrial refrigeration contractor Star Refrigeration, was expected to future proof the business for the next quarter-century and bring it in line with phase out of R22 systems.
Working closely with Lucite, Star’s engineers developed a bespoke industrial refrigeration system compliant with new R22 phase out regulations. Additional requests from Lucite included increased plant reliability, equipment longevity and a plan that allowed the new cooling system to be designed, constructed and commissioned while the existing plant was still operational to avoid any loss of productivity.
Graham Wallace, Lucite’s Project Manager, said, “Lucite wanted to replace the R22 chiller and increase capacity. Star delivered an energy efficient system that ensures plant reliability and future proofs the business to meet our environmental and legislative needs over the next 25 years.”
“Other challenges including space restrictions on site were met by laying out the packages and carrying out all inter-piping at their factory in order to replicate the site footprint. This gave us the confidence that the site installation would prove successful.”
“Finally, all match-marked parts were shipped separately and final connections were made once the packages were positioned on site.”
The major upgrade consisted of the installation of a 3.9MW – 10oC Glycol chilling system, running on environmentally friendly future-proof refrigerant ammonia (NH3). The entire system comprised of 3 off packages and 2 off screw compressor packages, each Leeds teams with 600KV 3.3 drive motors. Star also installed an innovative outdoor heat exchanger package equipped with water-cooled ST condenser, economizer and PSHE evaporator/separator.
Alan Walkinshaw, Star’s Sales Manager – Process Industries, said, “Installing the new system without jeopardizing the functionality of the old one did have its difficulties. However, the team is always up for a challenge and as usual, innovation and perseverance finally paid off and we came up with an effective solution.”
“Post project completion, the company stands to profit from three major benefits including greater productivity of present and future process needs, reduction of carbon footprint with the use of zero GWP and zero ozone depleting potential ammonia –boosting the company’s eco-credentials and enhanced plant reliability as well as increased operational efficiency through the use of variable loads.”
Lucite International now has complete control over the refrigeration plant using Star Refrigeration’s “next generation” control system “TELSTAR”, as well as a condition system for vibration monitoring.
