Sustainable Development Drives Overall Energy Efficiency Improvements in Coating Equipment

Detailed Interpretation: Under the “Dual Carbon” goals, coating—being a major energy consumer (including pretreatment, drying, and air conditioning systems)—has made energy efficiency a core evaluation metric in equipment procurement.

Comprehensive Thermal Management:

Waste Heat Recovery from Exhaust Gas:

High‑temperature exhaust from drying ovens and RTOs is passed through heat exchangers to preheat fresh air or process water, achieving significant energy savings.

Widespread Adoption of Heat Pump Technology:

High‑temperature heat pumps are used to supply thermal energy for pretreatment hot water tanks and low‑temperature drying chambers, offering higher energy efficiency than traditional gas‑fired boilers. 

Intelligent Energy Conservation for Air, Water, and Electricity:

Full Coverage of Variable‑Frequency Technology:

High‑power equipment such as supply and exhaust fans and water pumps widely adopt variable‑frequency drives (VFDs), automatically adjusting speed based on actual production load to avoid the inefficiency of “over‑sized equipment running at low load.”

Intelligent Airflow Regulation in Spray Booths:

Based on production line speed and workpiece shape, the system automatically calculates and adjusts the optimal supply and exhaust airflow, minimizing air conditioning energy consumption while ensuring coating quality.
