Using cryogenic cooling and freezing power to enhance safety, productivity, and environmental performance across a wide range of applications.
Many industrial production processes require rapid cooling and freezing capabilities. Liquid nitrogen (LIN) is an extremely effective cooling agent due to the low boiling point of (-196°C).
In addition, LIN is an environmentally sound alternative to conventional cooling processes, which often involve potentially harmful refrigerants, large quantities of water or dust and fumes. Because it is inert, LIN also eliminates the risk of fire or explosion.
LIN is commonly used to increase productivity and enhance quality in concrete mixing, asphalt paving, rubber hose production, glass production, plastic film blowing, grinding, welding and machining. Cryogenic condensation with LIN is also an effective way of purifying waste air and recovering valuable volatile organic compounds (VOC).
In the manufacture of Aluminium, dross cooling with Argon eliminates fumes and dust, while increasing recovery rates. The benefits of LIN in extrusion plants include higher production rates, improved surface finish and increased die lifetime.
Cryogenic solutions are also extremely popular in the food industry. LIN is a gentle and effective way of quickly lowering the temperature of food products to facilitate processing or preserve quality.
Linde also offers innovative cryogenic cooling solutions for reactor cooling and freeze drying in the pharma industry.
