Design
Warning
1. This catalog shows the specifications of a single
unit.
1. Check the specifications of the single unit (contents of this
catalog) and thoroughly consider the adaptability between
the customer system and this unit.
2. Although a protection circuit as a single unit is installed,
prepare a drain pan, water leakage sensor, discharge air
facility, and emergency stop equipment, depending on the
customer’s operating conditions. Also, the customer is
requested to carry out a safety design for the whole system.
2. When attempting to cool areas that are open to the
atmosphere (tanks, pipes), plan your piping system
accordingly.
When cooling open-air external tanks, arrange the piping so
that there are coil pipes for cooling inside the tanks and to
carry back the entire flow volume of circulating fluid that is
released.
3. Use non-corrosive materials for circulating fluid
contact parts.
The recommended circulating fluid is tap water or deionized
(pure) water. Using corrosive materials such as aluminum or
iron for fluid contact parts such as piping may cause clogging
or leakage in the circulating fluid circuit. Therefore, take suffi-
cient care when selecting fluid contact part materials such as
piping.
4. Design the piping so that no foreign matter enters
the chiller.
If foreign matter, such as scales in the piping, enters the circu-
lating fluid, this may cause the pump to malfunction. Therefore,
it is strongly recommended to install the particle filter.
5. The facility water outlet temperature (water-cooled
type) may increase up to around 60
°
C.
When selecting the facility water pipings, consider the suitability
for temperature.
Selection
Warning
Model selection
When selecting a thermo-chiller model, the amount of heat
generation from the customer equipment must be known. Obtain
this value, referring to the “Cooling Capacity Calculation” on pages
24 and 25 before selecting a model.
Handling
Warning
Thoroughly read the Operation Manual.
Read the Operation Manual completely before operation, and
keep the manual where it can be referred to as necessary.
Operating Environment / Storage Environment
Warning
1. Do not use in the following environment as it will
lead to a breakdown.
1. In locations where liquid that exceeds the conditions
required for the degrees of protection IPX4 may splash on
the product
2. In locations where dust, water vapor, salt water, and oil may
splash on the product
3. In locations where there are dust and particles
4. In locations where corrosive gases, organic solvents,
chemical fluids, or flammable gases are present (This
product is not explosion proof.)
5. In locations where the ambient temperature/humidity exceeds
the limits as mentioned below or where condensation occurs
During transportation/storage: 0
°
C to 50
°
C, 15% to 85%
(But as long as water or circulating
fluid are not left inside the pipings)
During operation: 2
°
C to 45
°
C, 30% to 70%
6. In locations where condensation may occur
7. In locations which receive direct sunlight or radiated heat
8. In locations where there is a heat source nearby and the
ventilation is poor
9. In locations where temperature substantially changes
10. In locations where strong magnetic noise occurs
(In locations where strong electric fields, strong magnetic
fields and surge voltage occur)
11. In locations where static electricity occurs, or conditions
which make the product discharge static electricity
12. In locations where high frequency occurs
13. In locations where damage is likely to occur due to lightning
14. In locations at an altitude of 3000 m or higher (Except
during storage and transportation)
*
For altitudes of 1000 m or higher
Because of lower air density, the heat radiation
efficiencies of the devices in the product will be lower in
the location at an altitude of 1000 m or higher. Therefore,
the max. ambient temperature to use and the cooling
capacity will lower according to the descriptions in the
table below.
Select the thermo-chiller considering the descriptions.
q
Upper limit of ambient temperature: Use the product in ambient
temperature of the described value or lower at each altitude.
w
Cooling capacity coefficient: The product's cooling
capacity will lower to one that multiplied by the
described value at each altitude.
15. In locations where strong impacts or vibrations occur
16. In locations where a massive force strong enough to
deform the product is applied or a weight from a heavy
object is applied
17. In locations where there is not sufficient space for
maintenance
18. Bevelled place
19. Insects or plants may enter the unit.
2. The product is not designed for clean room usage. It
generates particles internally.
