I. Preparation Before Installation


1. Site Selection

    • Choose a well-ventilated, dry, flat area with sufficient load capacity to install the liquid nitrogen freezer. Avoid damp, high-temperature, or corrosive environments.

    • Ensure there is enough space around the site for operating, maintaining the equipment, and storing and transporting liquid nitrogen.


2. Equipment Inspection


    • Before installation, carefully check all parts of the liquid nitrogen quick freezing machine to ensure they are undamaged and complete, with no transport-related damage.

    • Verify that the equipment's model, specifications, and technical parameters match the purchase contract.


3. Tools and Materials Preparation


    • Prepare the necessary installation tools, such as wrenches, screwdrivers, and pliers.

    • Gather required installation materials, including sealants, washers, and cables.


4. Safety Gear Preparation


    • Installers should wear appropriate safety gear, such as hard hats, protective gloves, and safety goggles.



II. Installation Steps


1. Positioning the Equipment

    • Carefully place the liquid nitrogen quick freezing equipment at the selected site using lifting equipment or a forklift, ensuring it is level and stable.


2. Connecting the Liquid Nitrogen Supply Line


    • Connect the liquid nitrogen supply line to the equipment's nitrogen inlet, using suitable seals to ensure a tight, leak-free connection.

    • Before connecting the line, make sure the inside is clean and free of debris.


3. Electrical Connections


    • Follow the electrical schematic to connect the power cable to the equipment's power interface.

    • Ensure the electrical connections are secure, properly grounded, and meet safety standards.


4. Installing the Ventilation System


    • If the equipment requires a ventilation system, install it according to the provided instructions to ensure proper airflow and the timely removal of nitrogen gas produced during operation.


5. System Testing


    •  After completing the installation steps, conduct system testing.

    • Check that all connections are secure and that there are no loose parts.

    • Test the electrical system to ensure it functions correctly.

    • Test the liquid nitrogen supply and freezing system to check the freezing performance and nitrogen usage.

III. Post-Installation Inspection and Acceptance


  • Visual Inspection: Check the equipment for any damage, deformation, or paint peeling.

  • Leak Check: Use a leak detector or soapy water to check the nitrogen supply line and other connections for leaks, ensuring there are none.

  • Operational Testing: Run the equipment for a while to observe its operation, including temperature control, pressure readings, and operational sounds.

  • Performance Acceptance: Based on the technical parameters and performance indicators, verify the freezing speed and effectiveness to ensure the equipment meets usage requirements.

IV. Precautions


  • Follow the installation manual and relevant standards strictly during the installation process; do not change steps or methods without approval.

  • Installers should have the necessary professional knowledge and skills, familiar with the installation process and safety precautions for liquid nitrogen freezers.

  • If any issues or abnormalities arise during installation or testing, stop work immediately, investigate the cause, and resolve the issue before continuing.

  • After installation, provide users with a detailed operating and maintenance manual and offer necessary training.
