FAQs
Why is the price shown not my final price?
All our air cooling units are engineered and built to order based on custom technical parameters. The final price varies depending on your required cooling capacity, evaporation area, fin spacing, fan motor brand, voltage configurations, and anti-corrosion options. Contact our engineering team with your room temperature and dimensions for a precise, tailored quote and CAD design.
What are your accepted payment terms for international orders?
We typically accept T/T (30% deposit, 70% balance paid before shipment) or Irrevocable L/C at sight. For long-term contracting partners or large-scale infrastructure projects, customized payment milestones can be negotiated after technical compliance verification.
Why choose a ceiling side-blow/dual-discharge design over standard coolers?
The low-profile ceiling side-blow configuration is specifically engineered to maximize warehouse vertical storage space. By delivering a horizontal, dual-direction air supply rather than a harsh direct blast, it creates a gentle and uniform airflow environment. This significantly reduces moisture loss and severe dehydration of perishable food products, making it the premier choice for food processing workshops, meat deboning rooms, and fruit packing zones.
Are the control valves and pressure gauges pre-installed before shipment?
Yes. To save your team on-site installation time and minimize labor costs, our ceiling units come factory-equipped with pre-assembled industrial control valves and factory-calibrated low-temperature pressure gauges. Every integrated core system undergoes a rigorous 100% pressure leakage test up to 3.0 MPa prior to assembly to ensure immediate, safe, and leak-free operation upon arrival.
Are you a factory or a trading company?
We are a verified source manufacturer. Our facility utilizes top-tier industrial CNC laser cutting systems and automated robotic bending centers to manage the entire fabrication process in-house. This heavy-duty automation eliminates manual assembly errors and guarantees perfect structural alignment, allowing us to provide factory-direct pricing with strict quality control.
What is your Minimum Order Quantity (MOQ) and delivery time?
Our Minimum Ordering Quantity is 1 unit. The standard production and delivery lead time is 30 days from project specification confirmation and deposit receipt, depending on the scale of custom engineering required.
What type of defrosting system is recommended for these ceiling units?
We offer two high-efficiency defrosting modes tailored to your specific cold storage temperatures: Electric Defrosting: Utilizes premium, highly insulated U-shaped electric heating tubes tightly integrated within the coil block for fast, uniform ice removal.
Water Defrosting: Equipped with an optional sieve plate water distribution system that drastically shortens defrost cycles and reduces overall energy consumption in larger processing areas. Our engineering team will recommend the optimal setup based on your frost accumulation patterns to maintain stable warehouse temperature control.
How do you verify technical compatibility before starting production?
Since our equipment is 100% custom-built, we follow a strict engineering verification protocol. Once your project parameters (room size, temperature drops, fluid type, and required capacity) are shared, our technical team calculates the exact coil surface area and generates a comprehensive BIM/CAD design. Production only begins after your engineering team reviews and signs off on the official technical drawings, ensuring zero alignment errors on-site.
