In the case of air-cooled refrigeration, the high temperature and high pressure refrigerant gas is cooled down by an air-cooled condenser with the ventilation of the fan, and becomes a liquid. In the case of water-cooled refrigeration, the refrigerant gas is cooled by a water-cooled condenser with the facility water in the facility water circuit, and becomes a liquid. The liquefied high pressure refrigerant gas expands and its temperature lowers when it passes through expansion valve A and vaporizes by taking heat from the circulating fluid in the evaporator. The vaporized refrigerant gas is sucked into the compressor and compressed again. When heating the circulating fluid, the high pressure and high temperature refrigerant gas is bypassed into the evaporator by expansion valve B, to heat the circulating fluid. Point The combination of precise control of expansion valve A for cooling, and expansion valve B for heating realized high temperature stability. Circulating fluid circuit The circulating fluid discharged from the pump, is heated or cooled by the user s equipment and returns to the thermo-chiller. The circulating fluid is controlled to a set temperature by the refrigeration circuit, to be discharged to the user s equipment side again by the thermo-chiller. Point Since the refrigeration circuit is controlled by the signal from 2 temperature sensors (for return and discharge), precise temperature control of the circulating fluid can be performed. Therefore, there is no necessity of absorbing the temperature difference in the circulating fluid with a large tank capacity, and realizes high temperature stability even with a small-size tank. Also, contributes to space-saving. Facility water circuit 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. Installation close to a wall is possible on both sides. (HRS12/18/24 Except option G) Reduced-height double condenser structure (HRS3/6) 1 Ventilation Ventilation Conventional Multiple air-cooled condensers are provided on the top and bottom. HRS3 Achieved a maximum reduction in the height of the product while expanding the cooling capacity, by providing overlapped air-cooled condensers. 1.8in (45mm) HRS HRS3 HRS5 HRS6

4 Series HRS Reduces the maintenance hours for the pump. Adoption of the magnet pump No external leakage of the circulating fluid because the sealless pump is used, and a periodic check of the pump leakage and replacement of the mechanical seal are not necessary. When the option, high-pressure pump, is selected and for HRS5/6, the mechanical seal pump is chosen. Shaped for easy supply of circulating fluid The angled supply port facilitates the supply of circulating fluid. Supply is possible even when 2 products are stacked. Easy check of the circulating fluid level Tool-less inspection and cleaning of air-cooled condenser Dustproof filter Integrated with the grill of the front panel. Mounting and removal can be done easily. Easy to mount/ remove due to magnet type! Easy to clean dust and cutting chips etc. stuck to the dustproof net by brush or air blow. Optional Accessories With casters (Removable) M8 thread Filter Particle filter set Removes foreign objects in the circulating fluid. Replacement type dustproof filter set Suitable for use in excessively dusty atmospheres. The disposable type filter saves time and effort of cleaning. Front panel 3 Convenient Functions (Refer to the Operation Manual for details.) 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. Unit conversion function Temperature and pressure units can be changed. Orange indicator lights up. Temperature unit Pressure unit Power failure auto-restart function Automatic restart from stoppage due to power failure etc. is possible without pressing the key and remote operation. 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. 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. Independent operation of the pump The pump can be operated independently while chiller is powered off. You can check piping leak and remove the air.

Note 1) It should have no condensation. Note 2) If tap water is used, use water that conforms to Water Quality Standards of the Japan Refrigeration and Air Conditioning Industry Association (JRA GL cooling water system - circulating type - make-up water). Note 3) q temperature: 77 F (25 C), w Circulating fluid temperature: 68 F (2 C), e Circulating fluid rated flow, rcirculating fluid: Tap water, t Facility water temperature: Refer to the cooling capacity graph on pages 13 and 14 for details. Note 4) Use a 15% ethylene glycol aqueous solution if operating in a place where the circulating fluid temperature is 5 F (1 C) or less. Note 5) Outlet temperature when the circulating fluid flow is rated flow, and the circulating fluid outlet and return port are directly connected. Installation environment and the power supply are within specification range and stable.
