Circulating Fluid Temperature Controller Refrigerated Thermo-cooler Series HRG 1.1kW / 2.3 kW / 4.8 kW, 9.5 kW / 14.5 kW 1.1kW / 2.3 kW / 4.8 kW, 11.0 kW / 16.5 kW Temperature stability: +1 / +0.5°C – °C – Temperature range setting: 5 to 35°C (Air-cooled refrigeration) Makes cooling water easily available, anytime, anywhere. (Proportional valve PID control) Temperature control of LCD panels Example: Cooling an LCD panel Temperature control of welding torches Related Products Application Examples Can be used in many applications other than those shown below. Refer to “Application Examples” section of this catalog. As a replacement for a cooling tower Example: Laser welding Cooling plate With casters (Option) Can be used for cooling during transfer to processing, before and after resist coating and firing of the glass substrate. Can be used to supply cooling water to welding torches or commercially available laser welding devices, and to prevent overheating of the torch or the oscillation tube. Technical Data (Refrigerator ON/OFF control) (Water-cooled refrigeration) Installing extra cooling towers can be troublesome. The HRG series (air-cooled refrigeration) can be moved easily to wherever you need it, when you need it. Cooling water is supplied from the attached hose.

Energy Saving Power consumption: Max. When the circulating fluid reaches a certain preset temperature, the refrigerator stops temporarily (idling stop) and the temperature is adjusted (refrigerator ON/OFF control). Stopping the refrigerator for longer periods of time and operating at low load (idling mode) reduces power consumption dramatically. Even in processes where there is heat loading, performance is at least as good as that of inverter control. Idling mode Note): 1.45 kW Process mode: 1.45 kW Inverter control Refrigerator ON/OFF control (HRG002-A) Note) Operating conditions: Process mode:...

Space Saving External volume: Max. 23% reduction Footprint: Max.12% reduction (SMC comparison) Conventional model Improvements in the HRG’s high-performance heat exchanger have enabled the size of the unit to be reduced, with corresponding reductions in mass and space needed for installation. Install directly against the wall for further reduction in installation space Thermo-cooler (Air-cooled refrigeration) Ventilation Ventilation Space saving Cooling capacity: • Aqueous solution of 15% ethylene glycol • Clear water, Deionized water Note) A maximum cooling capacity of 16.5 kW has been achieved...

Model Selection Guide to Model Selection 1. Which is best for you: a water-cooled refrigeration or an air-cooled refrigeration? You should base your choice on the configuration of your equipment. Thermo-cooler series refrigeration methods Water-cooled refrigeration Requires facility water equipment (cooling tower etc.) as well as electrical power supply. This type provides stable cooling performance year round, regardless of ambient temperature changes. Air-cooled refrigeration Only electrical power supply is needed. Facility water equipment is not necessary, so the system is easy to install...

Model Selection Cooling method : Air-cooled refrigeration Circulating fluid temperature: 20°C Fluid : Clear water Power supply frequency : 60 Hz Required cooling capacity : 4.2 kW Example: Customer requirements 1 to 5 Based on the results of 1 to 5, refer to the graph of cooling capacity of an air-cooled refrigeration Thermo-cooler at 60 Hz (page 16). On the same graph, plot the intersections between the customer’s required temperature (20°C) and cooling capacity (4.2 kW). Refer to the same graph that can be used for ethylene glycol aqueous solution (15% or less.) [Cooling Capacity Graph] Cooling...

Model Selection Calculation of Required Cooling Capacity Example 1: When the heat generation amount in the customer's equipment is known. The heat generation amount can be determined based on the power consumption or output of the heat generating area — i.e. the area requiring cooling — within your facility.∗ (1) Derive the amount of heat generated from the power consumption. Power consumption P: 3.5 [kW] Q = P = 3.5 [kW] Cooling capacity = Considering a safety factor of 20%, 3.5 [kW] x 1.2 = 4.2 [kW] I: Current V: Power supply voltage P (2) Derive the amount of heat generated from the power...
