Application areas:
Glycol air coolers are suitable for constant temperature refrigeration or controlled atmosphere refrigeration of fruits and vegetables. They are widely used in air conditioning systems in food production workshops and are suitable for air conditioning refrigeration systems in other industries.
Product features:
Good cooling effect, low noise, long range, ensuring stable operation
Adopting floating coil technology, the structure is reliable and the service life is long
Adopting a front row arrangement of fins to ensure a small temperature difference between the surface temperature of the fins and the inlet air temperature, slowing down the frosting rate
Copper tubes can be used as heat exchange tubes, and aluminum sheets with hydrophilic films can be used as fins. Italian tube expansion equipment and technology are adopted to ensure high heat transfer efficiency of the evaporator coil
Adopting automatic welding technology and equipment to ensure product quality
The shell can be made of galvanized sheet with surface electrostatic spraying treatment, or stainless steel sheet
● Using stainless steel connectors and fasteners
Adopting high-quality and low-noise German brand axial flow fans to ensure working time
● Adopt electric heating defrosting or air defrosting methods, etc
● Diverse product varieties with a wide range of applications
