FAQ

Home / FAQ
  • In which industries are your drying ovens/incubators/muffle furnaces primarily used?

    Our equipment has a wide range of applications. Drying ovens are commonly used for drying in the electronics and pharmaceutical industries; incubators are mainly used for microbial culture in pharmaceuticals and disease control; muffle furnaces and tube furnaces are widely used in material sintering and heat treatment in university research and aerospace fields. Our technical engineers can provide you with tailored advice for your specific application scenarios.

  • What are the core technological advantages of our equipment?

    Our core technological advantages are reflected in three points:
    1. Precise Temperature Control: Utilizing microcomputer PID intelligent temperature control, resulting in minimal temperature fluctuations and high uniformity.

    2. Reliability and Durability: Based on 23 patented technologies and using high-quality materials, the equipment ensures long-term stable operation.

    3. Intelligent Safety: Equipped with multiple safety functions such as over-temperature protection and power-off memory, ensuring user and experimental safety.

  • What is the difference between a "vacuum chamber" and a "drying oven"?

    The main difference lies in the working environment:

    Drying oven: Drys under normal pressure through heating and air circulation, suitable for most high-temperature resistant samples.

    Vacuum chamber: Operates under negative pressure, lowering the boiling point of liquids and achieving rapid low-temperature drying, particularly suitable for heat-sensitive and easily oxidized materials.

  • Does the equipment support customization?

    Yes. As a high-tech enterprise integrating design and production, we have strong non-standard customization capabilities. You can provide specific requirements such as temperature range, size, and material (e.g., stainless steel), and our R&D team will provide you with customized solutions.

  • How to choose the right model?

    You can start with the following key parameters:

    Temperature range: The highest operating temperature required for your experiments.

    Inner chamber size: Determined by the sample volume and container size you process each time.

    Special functions: Whether you need programmed temperature control, remote monitoring, nitrogen atmosphere, etc.

    Our sales engineers are always ready to assist you in the selection process.

  • How long after payment will it be shipped?

    For standard models, we usually arrange shipment within 5-7 business days after receiving payment. For customized products, the delivery date will be negotiated based on specific process requirements and written into the contract to ensure on-time delivery.

  • What after-sales services do you provide?

    We offer comprehensive after-sales support:

    Free technical support: Lifetime telephone and online remote technical support.

    Warranty period: One-year warranty for the entire machine, with an even longer warranty for core heating elements.

    Repair service: Free repair for non-human-caused problems within the warranty period; paid repair services are available after the warranty period, charging only for the cost of materials.

    Training: We provide detailed equipment operation manuals and online operation training.

  • How do I report a malfunction if my device fails?

    You can contact us in either of the following ways:

    Service Hotline: Call our nationwide service hotline (please fill in the specific number on the "Contact Us" page of our website).
