Strict Control of cold plunge Production Lines
We have divided quality control into multiple stages to ensure comprehensive management from raw materials to finished products.

Raw Material Inspection
Raw materials form the basis of product quality. To meet specific requirements, our company implements strict screening and inspection standards during the manufacturing process, ensuring that key materials such as stainless steel and cold-rolled steel meet the necessary conditions.
We also maintain close partnerships with our suppliers, enabling effective traceability of raw materials—an essential factor in ensuring product quality and performance consistency.

Production Process Quality Control
We implement comprehensive quality control to ensure every unit meets the highest standards of safety and performance. The intelligent and automated production line continuously monitors key processes such as temperature control, sealing integrity, water circulation, and electrical connections. By analyzing parameters like temperature deviation, water flow rate, and energy efficiency in real time, the system quickly detects and corrects any abnormalities to maintain optimal conditions. Rigorous in-process inspections and final functional testing further enhance product consistency, reduce human error, and guarantee that each cold plunge unit is fully verified and compliant with international safety standards before leaving the factory.

100% Comprehensive Inspection Before Delivery
Before shipment, every cold plunge unit undergoes a comprehensive quality inspection to ensure optimal performance and reliability. Each product is thoroughly tested for temperature stability, cooling efficiency, water circulation, and electrical safety under simulated working conditions. The surface finish, sealing performance, and structural integrity are also carefully examined to prevent any potential leakage or malfunction during use. Only after passing multiple rounds of functional and safety tests is the unit approved for packaging. This strict pre-shipment inspection process guarantees that every cold plunge delivered to customers meets our highest standards of quality, safety, and durability.
