Sub-zero and Cryogenic Temperatures for Heat-treated Parts

This cabinet freezer is designed for processes where temperatures close to that of cryogenic nitrogen may be necessary. CRYOFLEX^® C is ideally suited to batch production with front loading. An electric cryogenic valve controls the injection of LIN into the cabinet. Depending on the size of the freezer, it comes with up to three fans inside the chamber to create extremely uniform temperature distribution, allowing for optimum performance and efficiency. Combining cooling and heating in one unit, it supports temperatures as low as -180°C (-292°F) and as high as +300°C (+572°F).

CRYOFLEX C highlights

• PLC-controlled cooling and heating with recipes
• Gaseous nitrogen purge to prevent icing during reheating
• Additional thermocouple for batch monitoring
• Guillotine door to enable automatic loading and unloading if the freezer is part of a furnace line
• Upgradability to the requirements of AMS 2750 / CQI-9

We developed this continuous contact freezer to cool down moving blade strips more effectively. Up to eight strips can be cooled in parallel and the total length of CRYOFLEX^® CC can be adapted to the feed rate of the overall line. The standard temperature range extends from room temperature to -160°C (-256°F) on the cooling plate.

CRYOFLEX CC highlights

• Productivity and capacity gains
• Less maintenance
• Reduced energy costs
• Consistent product properties
• Easy integration into existing production system
• Climate-friendly as compressor is not required

This continuous conveyor belt in a sub-zero tunnel was developed specifically for operators keen to avoid unnecessary handling and transportation of parts requiring sub-zero treatment. The CRYOFLEX^® T freezer can be easily integrated into continuous hardening lines. It is well suited to mass production of small or thin parts such as injectors, springs, nuts and bolts. The standard temperature range extends from room temperature to -110°C (-166°F)

CRYOFLEX T highlights

• Customized models available on request
• Ease of integration
• Easy control over cooling and process time by adjusting the conveyor speed and gas volume injected
• Heavy-duty version available for increased mesh belt load

This box freezer is designed for processes where temperatures close to that of LIN may be necessary. The CRYOFLEX^® B is ideal for small production batches and is loaded from the top. In the freezer, the injection of LIN is controlled via an electrically operated cryogenic valve. The standard temperature range extends from room temperature to -180°C (-292°F).

CRYOFLEX B highlights

• Customized models available on request
• Flexibility for small batches
• Gaseous nitrogen purge to prevent icing during reheating
• Additional thermocouple for precise and controlled cooling
