PRODUCTS – Advantages of Plate Type - Higher heat transfer efficiency
Inerratic welding spot The fluid direction & speed continuously change, intensifying heat exchange
Uniform water film
Large flow cross profile Long distance from core layer to edge stratified gas flow
Plate

PRODUCTS – Advantages of Plate Type - Simple maintenance and longer service life
Plate Easily find out the leak point Easy to replace the damaged
plate No influence in total heat
exchange area
Coil Harder to find the leak point Blocked the damaged tube The total heat exchange area
will decrease

PRODUCTS – Frequency Converter
Principles:
Control running of fans according to outlet pressure(for evaporative condenser) or outlet temperature(for cooling tower)
feedback signals.
When the ambient temperature is continuously changing, the control cabinet is capable to collect operating parameters
automatically and take the necessary adjustments to make sure that the system is always running at relatively economical
conditions, and bring significant energy saving effects, especially lower-temperature seasons.
Advantages:
Energy efficient
Intelligent control
User-friendly
Low operation costs
