Note 1) For water-cooled refrigeration Note 2) It should have no condensation. Note 3) If clear water is used, use water that conforms to Water Quality Standards of the Japan Refrigeration and Air Conditioning Industrial Association (JRA GL-02-1994 cooling water system - circulating type - make-up water). Note 4) q Ambient temperature: 25°C, w Circulating fluid temperature: 20°C, e Rated circulating fluid flow rate, r Circulating fluid: Clear water, t Facility water temperature: 25°C Refer to the cooling capacity graph on page 1292 for details. Note 5) Use a 15% ethylene glycol aqueous solution if operating in a place where the circulating fluid temperature is 10°C or less. Note 6) 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. Note 7) The capacity at the Thermo-chiller outlet when the circulating fluid temperature is 20°C. Note 8) Required min. flow rate for cooling capacity or maintaining the temperature stability. The specification of the cooling capacity and the temperature stability may not be satisfied if the flow rate is lower than the rated flow. (In such a case, use a by-pass piping set (sold separately).) Note 9) Purchase an earth leakage breaker with current sensitivity of 30 mA separately. (A product with an optional earth leakage breaker (option B) is also available.) Note 10) Front: 1 m, height: 1 m, stable with no load, Other conditions → Note 4) Note 11) Weight in the dry state without circulating fluids Note 12) Required flow rate when a load for the cooling capacity is applied at a circulating fluid temperature of 20°C, and rated circulating fluid flow rate and facility water temperature of 25°C. Note 13) It is not provided for HRS050. How to Order Specifications . There are different values from standard specifications. Refer to page 1299 for details.
