※1 During operation at cold water temperature of 20 ° C and ambient temperature of 32 ° C. The cooling capacity is 95% or more of the display capacity.
※2 It varies with ambient temperature only during start-up operation.
※3 When the current load within ± 10% continues and ambient temperature · power supply etc is stable. However, except at startup and when the compressor turns on and off with less cooling load.
※4 The phase unbalance of power supply voltage should be within ± 3%.
※5 Maximum operating current within the operating range.
※6 It incorporates an overcurrent protection combined type earth leakage breaker as standard.
※7 The driving sound is 1 m front and 1 m high.
※8 Please use antifreezing liquid from 0 ° C to 3 ° C as the setting liquid temperature.
※9 Clean water and 30 to 40% industrial ethylene glycol aqueous solution are recommended for liquid (cold water) used in this machine. However, when using an industrial ethylene glycol aqueous solution of 30 to 40%, please note that the cooling capacity drops by about 10% . Also, in the case of pure water, please set the electric conductivity to 1 μS / cm or more.
※10 Apparatus exhaust heat quantity (kW) is about 1.3 times the cooling capacity
