Warning
1. This catalog shows the specifications of the
Thermo-con.
1. Check the detailed specifications in the separate “Product
Specifications”, and evaluate the compatibility of the Thermo-con
with user’s system.
2. Although the protection circuit as a single unit is installed, the user is
requested to carry out the safety design for the whole system.
1. Thoroughly read the Operation Manual.
Read the Operation Manual completely before operation, and keep
this manual available whenever necessary.
2. If the set temperature is repeatedly changed by 50°F
(10°C) or more, the Thermo-con may fail in short
periods of time.
1. Keep within the specified ambient temperature and
humidity range.
Also, if the set temperature is too low, condensation may form on
the inside of the Thermo-con or the surface of piping even within the
specified ambient temperature range. Dew condensation can cause
failure, and so must be avoided by considering operating conditions.
2. The Thermo-con is not designed for clean room
usage.
The pump and fan generate dust.
3. Low molecular siloxane can damage the contact of
the relay.
Use the Thermo-con in a place free from low molecular siloxane.
1. Avoid strong vibration and/or impact.
The product is precision equipment. Do not apply vibration or impact
during transportation.
2. Caution when moving a heavy object.
This product is heavy. Use adequate caution to avoid injury when
picking up and setting down the product, and dropping accidents
should be avoided.
3. Installation
When installing the product into a rack, it should be designed that
the product weight is held with the bottom surface of the product.
Use the handles on the front side of the product when
installing/removing the product to/from the rack.
1. The inlet for radiation air must not be exposed to
particles and dust as far as possible.
2. Do not let the inlet and outlet for radiation air get
closed.
3. If more than one Thermo-con is used, consider their
arrangement so that the downstream sides of the
Thermo-cons suck radiation air from the upstream
sides.
Otherwise, the performance at the downstream sides may
deteriorate. Also, the set temperature may not be achieved
depending on the value of the set temperature and the load. In such
a case, take countermeasures such as changing the direction of the
Thermo-cons to prevent the deterioration of performance.
4. Filters are not built-in. Mount them as necessary.
5. Flow rate of the heat dissipation air is approximately 2
m
3
/min. The heat generation is approximately 600 W at
maximum.
1. Use a fluid that is listed in the specifications.
2. Deionized water (with an electrical conductivity of
approximately 1 µS/cm) can be used, but may lose its
electrical conductivity.
Also, if a facility supplying deionized water is used, the Thermo-con
may be damaged by static electricity.
3. If deionized water is used, bacteria and algae may
grow in a short period.
If the Thermo-con is operated with bacteria and algae, its cooling
capacity or the capacity of the pump may deteriorate.
Exchange all deionized water regularly depending on the conditions
(once a month as a guide).
4. If using a fluid other than those listed in the
specifications, please contact SMC beforehand.
5. The maximum operating pressure of circulating fluid
circuit is 15 psi (0.1 MPa).
If this pressure is exceeded, leakage from the tank in the
Thermo-con can result.
6. Select a pipe with a length and diameter which allow a
flow rate of 0.13 gal/min (0.5 L/min) or more for the
circulating fluid.
If the flow rate is less than 0.13 gal/mon (0.5 L/min), the Thermo-con
cannot provide precise control, but also can fail because of the
repeated cooling and heating operation.
7. A magnet driven pump is used as a circulating pump.
A fluid which contains metal powders such as iron powder cannot be
used.
