According
to the difference of fin materials , there are two series:
●STEEL FIN SERIES-NH3
●ALUMINUM FIN SERIES-NH3
STEEL FIN SERIES

- Technical features
The industrial air coolers are suitable for installing the rooms
designed for the preserving, freezing and general cold storage.Because
of the impacted design, they can save more store space.
The items are categorized according to their applications:
●The uniform fin spacing configuration
·7mm fin spacing for high and medium room temperatures(5~-10℃)
·10mm fin spacing for medium room temperatures(-10~-18℃)
·12mm ,14mm fin spacing for low room temperatures(-18~-35℃)
●The variable fin spacing configuration
·7/12mm fin spacing for high and medium room temperatures(5~-10℃)
·10/14mm ,12/14mm fin spacing for medium and low
room temperatures(-10~-35℃)
- Manufacturing features
●Cooler coil
·Hot-dip galvanized
Using rippled steel fins and super thin - walled steel tubes,
it helps to achieve its highest efficiency when utilizing the current
refrigerant type NH3, R22 and the cooling medium water containing
glycol .
● Casing
Three kinds of material for choice:
·galvanized steel sheet (suitable for preserving ,freezing and general
cold storage )
·spray plastic sheet (recommended for comfortable
air - conditioning rooms)
·stainless steel sheet ( recommended for food processing
rooms)
●Defrosting
·Water defrosting( by water spray)
·Electric defrosting (stainless steel electric heaters in coil and
drip tray)
·Hot gas defrosting (hot gas in coil and tray)
●Fans
·External rotor motors
·The motor and impeller are constructed as an integral unit, which
leads to energy exchange and low noise with high-efficiency
·The motors are equipped with thermal contacts.
·Die cast aluminum impeller
·With the special lubricating oil , the lowest operation temperature
can reached -40℃.
·The streamline fan guard expands the scattering
range of the air ,and ensures the smooth of the air distribution.
-Application
Refrigerant: NH3,, R22
Cooling medium: Water containing glycol
- Method of selection:
For the selection of coolers, the quick selection tables
have been devised. The cooling capacities refer to the temperature
difference △t between the room temperature and the evaporating temperature
of refrigerant.
Once △t, evaporating temperature t0
and cooling capacity Q0 are determined, the selection can be easily
done.
Notes:
·For other types of refrigerants or cooling medium and the specical
requirements, please consult Technical Department of our company.
·Consumers may select appropriate types according as
the method provided by
our company. If the detailed technical parameters being provided
,we would
like to select appropriate types for you.
