Thermo-chiller Series HRS
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-02-1994
cooling water system - circulating type - make-up water).
Note 3) qAmbient temperature: 25°C, wCirculating fluid temperature: 20°C, eCirculating
fluid rated flow, rCirculating fluid: Tap water, tFacility water temperature: 25°C
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 circu-
lating fluid temperature is 10°C or less.
Note 5) Outlet temperature when the circulating fluid flow is rated flow, and the circulating flu-
id outlet and return port are directly connected. Installation environment and the pow-
er supply are within specification range and stable.
Note 6)
The capacity at the thermo-chiller outlet when the circulating fluid temperature is 20°C.
Note 7) 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 8) 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 9) Front: 1 m, height: 1 m, stable with no load, Other conditions →Note 3)
Note 10) Weight in the dry state without circulating fluids
Note 11)
Required flow rate when a load for the cooling capacity is applied at a circulating fluid tem-
perature of 20°C, and circulating fluid rated flow and facility water temperature of 25°C.
Note 12) It is not provided for HRS050/060.
Note 13)
If the product is used at altitude of 1000 m or higher, refer to “Operating Environment/
Storage Environment” (page 41) Item 14 “*For altitude of 1000 m or higher”.
