    Frequently Asked Questions

    How does the air cooler reduce fan and vibration noise?
    The panel and side plates are well-constructed using a step structure, which effectively reduces the noise caused by the fan and fan vibration. Additionally, the water pan and side plate are designed to be easy to dismantle.
    What treatment is applied to ensure the shell's durability?
    The shell undergoes phosphating and surface spray treatments. This makes the surface smooth, highly corrosion-resistant, and ensures a longer product life span.
    What air tightness standards do these air coolers meet?
    Every unit undergoes a strict 2.6mpa air tightness test to satisfy the product's air tightness and safety requirements.
    How is the defrosting system designed for energy efficiency?
    The electric defrosting system uses high-insulation stainless steel heating tubes. Their reasonable distribution achieves a short defrosting time with high efficiency and low energy consumption. Users can also add a module to the controller to implement automatic defrosting control.
    What are the capacity differences between the SDJ, SDD, and SDL series?
    The series are rated under different temperature conditions: SDJ is based on an air inlet dry-bulb of -25℃ and evaporation of -31℃; SDD is based on an air inlet of -18℃ and evaporation of -25℃; and SDL is based on an air inlet of 0℃ and evaporation of -8℃.
    What kind of applications are these air coolers suitable for?
    These units are widely used in various cold storage environments, including fruit and vegetable preservation, special medical storage, flower preservation, red wine storage, aquatic product processing and storage, special testing, and food processing cold storage.
