*1: The capacity is derived under the conditions that the facility water temp. is 25°C and that the circulating fluid flow
rate is obtained at a specified flow rate of pump capacity. Applied to 50 / 60Hz.
*2: This is a system output temperature, with flow rate defined in pump capacity secured, when stabilized with no
disturbance. Its upper limit may be violated if an insufficient amount of the circulating fluid is present or a
disturbance to flow rate is observed.
*3: Water quality of The Japan Refrigeration and Air Conditioning Industry Association (JRA
GL-02-1994/Recirculating fluid of Cooling water system) shall be satisfied (See “7.1 Water Quality
Management’)
Additives such as preservative is NOT available. It not only deteriorates the performance, but also lead
to cause failure.
*4: The capacity is derived at the Outlet of this system when the circulating fluid temp. is at 20°C.
*5: This is a minimum amount of the fluid for operation of the Thermo Chiller outfitted with internal piping and heat
exchanger in this system. Circulating fluid temp.: 20°C
*6: This is an auxiliary space with a main tank capacity excluded. Available for circulating fluid recovery from external
piping and backup supply.
*7: This is the dimensions of panels, which is derived without protrusions such as a breaker handle.
*8: This is the mass of the system when it contains no circulating fluid.
*9: Facility water temp. is 25°C. There is required flow when adding load described on cooling capacity.
