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 user’s system and this unit.
2) Although the 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
user’s operating condition. Also, the user is requested to
carry out the 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 material for fluid contact of circu-
lating fluid.
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. Provide protection against corrosion
when you use the product.
Selection
Warning
Model selection
For selecting a model of thermo-chiller, it is required to know the
heat generation amount of the user’s equipment. Obtain the heat
generation amount, referring to “Cooling Capacity Calculation” on
pages 11 and 12 before selecting a model.
Handling
Warning
Thoroughly read the Operation Manual.
Read the Operation Manual completely before operation, and
keep this manual available whenever 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 water vapor, salt water, and oil may
splash on the product.
2) In locations where there are dust and particles.
3) In locations where corrosive gases, organic solvents,
chemical fluids, or flammable gases are present. (This
product is not explosion proof.)
4) In locations where the ambient temperature exceeds the
limits as mentioned below.
During transportation/storage: –15
°
C to 50
°
C (But as long
as water or circulating fluid
are not left inside the pipings)
During operation: –5
°
C to 45
°
C
∗
When the ambient tempera-
ture or circulating fluid tem-
perature is 10
°
C or below,
use the circulating fluid spec-
ified in "Operation at low am-
bient temperature or low cir-
culating fluid temperature".
5) In locations where condensation may occur.
6) In locations which receive direct sunlight or radiated heat.
7) In locations where there is a heat source nearby and the
ventilation is poor.
8) In locations where temperature substantially changes.
9) In locations where strong magnetic noise occurs.
(In locations where strong electric fields, strong magnetic
fields and surge voltage occur.)
10) In locations where static electricity occurs, or conditions
which make the product discharge static electricity.
11) In locations where high frequency occurs.
12) In locations where damage is likely to occur due to lightning.
13) In locations at altitude of 3000 m or higher (Except during
storage and transportation)
∗
For altitude 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
altitude of 1000 m or higher. Therefore, the maximum
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.
14) In locations where strong impacts or vibrations occur.
15) In locations where a massive force strong enough to
deform the product is applied or a weight from a heavy
object is applied.
16) In locations where there is not sufficient space for maintenance.
17) In locations where liquid that exceeds the conditions required
for the degrees of protection IPX4 may splash on the product.
18) Insects or plants may enter the unit.
2. The product is not designed for clean room usage. It
generates particles internally.
