Food and Beverage

To achieve optimal efficiency while meeting stringent health and safety standards, plants and manufacturers in the food and beverage industry have to maintain a complicated balancing act. John Crane makes it manageable by engineering reliable, specialized components that both improve productivity and eliminate contamination. From food processing plants to bottling, brewing and distilling plants, our products can withstand the challenges of any environment to consistently perform as expected and adhere to international HACCP standards.

In addition to reducing overall operation costs, John Crane products also aim to reduce the environmental impact of food and beverage processing by helping plants adhere to emissions regulations. Our process-specific components are engineered with the proprietary materials and clean-in-place designs needed to preserve nutritional standards and tolerate rigorous cleaning protocols.
