FAQ

Q1: Where are your main markets?

A: Our products have been exported to many markets around the world. We have rich project experience in Europe (where fire protection standards are strictly required), North America, the Middle East and Southeast Asia. We are particularly good at providing suitable solutions for different climatic conditions and regulatory environments. 

Q2: How do you ensure product quality?

A: Quality is our cornerstone. We have ISO 9001 quality management system certification, and our core products have passed international certifications such as CE and SGS. From raw material procurement to production completion, strict inspection is carried out throughout the entire process. Meanwhile, we welcome customers to designate a third party for factory inspection or pre-shipment inspection (PSI).

Q3:What temperature can the cold room reach?  

A: Standard walk-in cooler: 0~8℃, freezer room: -18~-25℃, dual-temperature cold room available. Container cold room and walk-in cooler cabinet are default at 0~8℃ for fresh keeping.

Q4: Is the container cold room movable?

A: Yes. It is reconstructed from standard 20ft/40ft shipping container and can be lifted and transported as a whole. Equipped with insulated panel enclosure, cold room entrance door and refrigeration outdoor unit, it is suitable for temporary site, farm pre-cooling and export projects.

Q5: How can the refrigeration board ensure long-term insulation effect and prevent condensation?  

A: It comes down to the core material and connections. We use high-density, low-thermal-conductivity PIR/PU cores with a special tongue-and-groove system, ensuring seamless, tight joints that minimize cold-bridge effect and guarantee airtightness to prevent condensation.

Q6: Can it be customized according to our size and color? 

A: Sure! Customized services are one of our core advantages. We support Size customization: Length, width and thickness can be produced according to the drawings. Color customization: We offer matching with standard color cards such as RAL and Pantone, or color matching based on samples. Performance customization: Adjust the plate type and base plate strength according to requirements such as wind pressure and load. Please provide your detailed technical requirements or drawings, and we will issue a customized solution.
