specification (Option)
∗1 It should have no condensation.
∗2 If tap water is used, use water that conforms to Water Quality Standards of the Japan Re-
frigeration and Air Conditioning Industry Association (JRA GL-02-1994 cooling water sys-
tem - circulating type - make-up water).
∗3 q Ambient temperature: 25°C, w Circulating fluid temperature: 20°C, e Circulating fluid
rated flow, r Circulating fluid: Tap water
Refer to the cooling capacity graph on page 10 for details.
∗4 Use a 15% ethylene glycol aqueous solution if operating in a place where the circulating
fluid temperature is 10°C or less.
∗5 Temperature at the thermo-chiller outlet 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.
∗6
The capacity at the thermo-chiller outlet when the circulating fluid temperature is 20°C.
∗7 Required minimum flow rate for maintaining the cooling capacity or temperature stability
The specification of the cooling capacity and the temperature stability may not be satis-
fied if the flow rate is lower than the rated flow. (In such a case, use a bypass piping set
(sold separately).)
∗8 Purchase an earth leakage breaker with current sensitivity of 30 mA separately.
∗9 Front: 1 m, height: 1 m, stable with no load, Other conditions → See ∗3.
