Compliant with safety standard for medical equipment IEC 661-1 (Air-cooled/2-A series) Power supply: Applicable to 1 V to 24 V (Air-cooled/-A series, Water-cooled/1-W, 3-W) Suitable to fluorinated fluids (Fluorinert TM FC-3283, GALDEN HT135) (Water-cooled/6-W, 12-W) Compatible with ethylene glycol 2% (Water-cooled/1-W, 3-W) Learning Control Function (Temp. control by external temperature sensor) This function adjusts the fluid temperature to the set value with an automatic offset setting. Set the external temperature sensor at the circulating fluid inlet located just in front of the heat source, which allows the Thermo-con to sample the fluid temperature. This function is effective when automatically adjusting for heat exhaust from piping, etc. If the external temperature sensor is installed directly on the heat source, the learning control function may not work property due to large heat volume or large temperature difference. Be sure to install the sensor at the circulating fluid inlet. Principle of Peltier Device (Thermo-module) A Peltier device (thermo-module) is a plate type element, inside which P-type semicon-ductors and N-type semiconductors are located alternately. If direct current is supplied to the Peltier device (thermo-module), heat is transferred inside the device, and one face generates heat and increases temperature while the other face absorbs heat and decreases temperature. Therefore, changing the direction of the current supplied to the Peltier device (thermo-module) can achieve heating and cooling operation. This method has a fast response and can shift quickly between heating and cooling, so temperature can be controlled very precisely.

It interposes a Peltier device (thermo-module) between the heat exchangers for the circulating fluid and facility water and controls the pulse width of supply direct current to achieve the target outlet temperature of circulating fluid precisely. The circulating fluid returns to the tank, and is transferred by the pump which is built in the Thermo-con, and goes through the heat exchangers and internal sensors and out from the circulating fluid outlet. Figure 2 shows an example of circulating fluid piping. The circulating fluid is transferred at a constant temperature by the pump. Technical Data Related Products 129

As a rule, SMC will not conduct on-site maintenance. Separately, the following parts have a limited life and need to be replaced before the life ends. Parts Life Expectation Description Expected life Pump 3 to 5 years Fan DC power supply 5 to 1 years 5 to 1 years Possible failure The bearing is worn so the pump fails to transfer the circulating fluid, which results in temperature control failure. The bearing uses up lubrication and makes the fan unable to supply enough air, which deteriorates the cooling and heating capacity. The capacity of the electrolytic condenser decreases, and causes abnormal voltage which results in DC power supply failure and stops the Thermo-con. Display panel 5, hours (approx. 5 years) The display turns off when the backlight of the LCD reaches the end of its life. 14

Series -A Specific Product Precautions 2 Be sure to read this before handling. Refer to back page 1 for Safety Instructions and back pages 2 to 5 for Temperature Control Equipment Precautions. Caution Caution Radiation Air 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.If dust adheres to the filter, remove dust with a vacuum cleaner or a dry cloth. 5. Do not operate without the filter. Otherwise, dust may accumulate on the heat sink and electrical components, causing abnormal heating. Circulating Fluid 1. Use tap water or fluid which will not damage the wetted material. (Stainless steel 33, Stainless steel 34, EPDM, Polypropylene, PE, PPE, Ceramics, Polyurethane) 2. Deionized water (with an electrical conductivity of approx. 1 µs/cm) can be used, but may lose its electrical conductivity. Also, if a facility supplying deionized water is used, the Thermocon may be damaged by static electricity. 3. If deionized water is used, bacteria and algae may grow in short periods of time. 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 water, please contact SMC beforehand. 5. The maximum operating pressure of circulating fluid circuit is 14.5 psi (.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.26 gpm (1 L/min) or more (2) or.79 gpm (3 L/min) or more (6) for the circulating fluid. If the flow rate is less than these values, 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 circulat-ing pump. A fluid which contains metal powders such as iron powder cannot be used. 8. The Thermo-con must not be operated with-out circulating fluid. The pump can break due to idling. Caution Circulating Fluid 9. If the tank lid is opened after the supply of circulating fluid, the circulating fluid may spill out depending on the condition of external piping. 1. If an external tank is used, the circulating fluid may spill out from the internal tank lid depending on where the external tank is installed. Check that the internal tank has no leakage if using an external tank. 11. If there is a point where fluid is released to atmosphere externally (tank or piping), minimize the piping resistance at the circulating fluid return side. If the piping resistance is too large, the piping may be crushed, or the built-in circulator tank may be deformed or cracked because the pressure in the piping for return will become negative. The built-in circulator tank is made of resin (PE). Therefore, the tank may be crushed if the pressure is negative. Special attention must be paid if the flow rate of the circulating fluid is high. To avoid getting negative pressure less than 2.9 psi (.2 MPa), the piping for return should be as thick and short as possible to minimize the piping resistance. It is also effective to restrict the flow rate of circulating fluid or remove the gasket of internal tank for the release to atmosphere. 12. Fluorinated fluid is outside of the specifications. If it is used in the Thermo-con, static electricity will be generated by the flow of fluid. This static electricity may be discharged to the board of the Thermo-con, causing damage or operation failure and loss of data of such as set temperature. Also, as the specific gravity of the fluorinated fluid is 1.5 to 1.8 times of water, the pump will be overloaded, which also causes fluorinated fluid to be outside the specifications. Therefore, if fluorinated fluid is used, please contact SMC and we will introduce a suitable special product (water-cooled type). 13. Avoid operation with cavitation or bubbles due to low fluid level in the tank. This may shorten the pump life. 14. If clear water is used, it should satisfy the quality standards shown below.

Caution Warning Series -A Specific Product Precautions 3 Be sure to read this before handling. Refer to back page 1 for Safety Instructions and back pages 2 to 5 for Temperature Control Equipment Precautions. Communication 1. The set value can be written to EEPROM, but only up to approx. 1 million times. In particular, pay attention to how many of times the writing is performed using the communication function. Maintenance 1. Prevention of electric shock and fire Do not operate the switch with wet hands. Also, do not operate the Thermo-con with water left on it. 2. Action in the case of error If any error such as abnormal sounds, smoke, or bad smell occurs, cut off the power at once, and stop supplying and conveying fluid. Please contact SMC or a sales distributor to repair the Thermo-con. 3. Regular inspection Check the following items at least once a month. The inspection must be done by an operator who has sufficient knowledge and experience. a) Check of displayed contents. b) Check of temperature, vibration and abnormal sounds in the body of the Thermo-con. c) Check of the voltage and current of the power supply system. d) Check for leakage and contamination of the circulating fluid and intrusion of foreign objects to it, and subsequent replacement of the fluid. e) Check for flow condition, temperature and filter of radiation air. 144
