Series HRS Convenient Functions Unit conversion function The unit can be changed between C and F and MPa and PSI. Orange indicator lights up. Independent operation of the pump The pump can be operated indepnedently while chiller is powered off. It is possible to check piping leak and remove the air. Timer operation function Timer for ON and OFF can be set in units of.5 h up to 99.5 h. Ex.) Can set to stop on Saturday and Sunday and restart on Monday morning. Ex. SE.2 ON timer Timer The time remaining can be checked. Low tank level detecting function The reduction of the fluid level in the tank is notified by alarm code. Red indicator lights up. Power failure auto-restart function Automatic restart from stoppage due to power failure, etc. is possible without pressing the key and remote operation. Key-lock function Can be set in advance to protect the set values from being changed by pressing keys by mistake. Function to output a signal for completion of preparation Notifies by communication when the temperature reaches the pre-set temperature range. Anti-freezing operation function If the temperature approaches freezing point, e.g. in winter at night, the pump operates automatically and the heat generated by the pump warms the circulating fluid, preventing freezing. Self Diagnosis and Check Display for Easy Maintenance Display of 35 types of alarm codes Operation is monitored all the time by the integrated sensor. Should any error occur, the self diagnosis result is displayed by the applicable alarm code from 35 types. This makes it easier to identify the cause of the alarm. Can be used before requesting service. Ex. AL1 Low level in tank Changeable alarm set values Setting item Set value Circulating fluid discharge temperature rise Circulating fluid discharge temperature drop Circulating fluid discharge pressure rise Circulating fluid discharge pressure drop 5 to 48 C 1 to 39 C.5 to.75 MPa.5 to.18 MPa Flashing Lights up PV Alarm code Alarm codes notify of checking times.

Temperature Control Equipment Features 2
Chillers are products that control the temperature of heat sources in customers devices and equipment using temperature-controlled circulating fluid. Maintaining a fixed temperature can improve the quality, reliability and service life of devices or equipment. Semiconductors Machine tools Physical and chemical/ analytical equipment Food products Medical/ Pharmaceutical Measuring devices etc. When There is no cooling tower. Tap water is being used. Even without a cooling tower, an air-cooled refrigerated chiller can be used to easily supply cooling water. Less tap water used! Dripping stops When There is a cooling tower, but high temperatures in summer or low (freezing) temperatures in winter make cooling water temperatures unstable. Cooling water at a consistent temperature can be supplied regardless of the season. Cooling tower Application Examples Laser machining Cooling of laser irradiated part UV curing device (printing, painting, bonding and sealing) Cooling of UV lamp X-ray (digital) instrument Temperature control of X-ray tube and X-ray light sensing part Electronic microscope Temperature control of electron-beam irradiated part X-ray tube Light sensing part Laser marker Cooling of laser irradiated part Ultra sonic wave inspection machine Temperature control of ultra sonic wave laser part Features 3

After the circulating fluid will cool the customer s machine side, it will heat up and return to the Thermo-chiller. High-temperature, high-pressure refrigerant gas compressed by the compressor is made to release heat by the condenser, and turns to liquid. As the liquefied high-pressure refrigerant passes through the expansion valve A, it expands and cools down; as it passes through the evaporator, heat is extracted from the circulating fluid and it evaporates. The evaporated refrigerant is once again sucked in and compressed by the compressor, and the above cycle is repeated. The expansion valve B is open to heat the circulating fluid. For water-cooled refrigeration HRS-W- The water control valve opens and closes to keep the refrigerant gas pressure consistent. The facility water flow rate is controlled by the water control valve. Communication Function The serial communication (RS232C/RS485) and contact I/Os (2 inputs and 3 outputs) are equipped as standard. Communication with the customer s machine and system construction are possible, depending on the application. A 24 VDC output can be also provided, and is available for a flow switch (SMC s PF2W, etc.). Remote signal I/O through serial communication The remote operation is enabled (to start and stop) through serial communication. HRS Circulating fluid temperature setting PC Start and stop Alarm and operation status (start, stop, etc.) signal output The alarm and status generated in the product are assigned to 3 output signals based on their contents, and can be output.

Regarding the circulating fluid pipings, consider carefully the suitability for shutoff pressure, temperature and circulating fluid. If the operating performance is not sufficient, the pipings may burst during operation. 2. Select the piping port size which can exceed the rated flow. For the rated flow, refer to the pump capacity table. 3. When tightening at the circulating fluid inlets and outlets, drain port or overflow outlet of this product, use a pipe wrench to clamp the connection ports. 7 Caution Warning Caution Piping 4. For the circulating fluid piping connection, install a drain pan and wastewater collection pit just in case the circulating fluid may leak. 5. This product series consists of circulating fluid temperature controllers with built-in tanks. Do not install equipment on your system side such as pumps that forcibly return the circulating fluid to the unit. Also, if you attach an external tank that is open to the air, it may become impossible to circulate the circulating fluid. Proceed with caution. Electrical Wiring 1. Grounding should never be connected to a water line, gas line or lightning rod. 1. Communication cables should be prepared by the customer. 2. Ensure a stable power supply with no voltage surges and distortion. In particular, operating failure can result when the voltage ramp rate (dv/dt) exceeds 4 V/2 µ sec at the zero cross-over point. Voltage dv dt dv dt = Voltage ramp rate Time

Equipped with a unit conversion function. Displays the unit of display pressure (default setting: MPa). Enables remote operation (start and stop) by communication. Lights up during remote operation. Lights up when the product is started, and goes off when it is stopped. Flashes during stand-by for stop or anti-freezing function, or independent operation of the pump. Flashes with buzzer when alarm occurs. Lights up when the surface of the fluid level lamp falls below the L level. Equipped with a timer for start and stop. Lights up when this function is operated. Equipped with a power failure auto-restart function, which restarts the product automatically after stopped due to a power failure, is provided. Lights up when this function is operated. Makes the product start or stop. Shifts the main menu (display screen of circulating fluid discharge temperature and pressure) and other menus (for monitoring and entry of set values). Changes the item in menu and enters the set value. Decreases the set value. Increases the set value. Press the [MENU] and [RUN/STOP] keys simultaneously. The pump starts running independently to make the product ready for start-up (release the air). Press the [] and [] keys simultaneously. The alarm buzzer is stopped and the [ALARM] lamp is reset. This unit has 35 types of alarms as standard, and displays each of them by its alarm code on the PV screen with the [ALARM] lamp ([LOW LEVEL] lamp) lit up on the operation display panel.
