Cooling Capacity
Pump Capacity
[50 Hz]
[60 Hz]
*
The pump capacity is the capacity of CH1 when 2 L/min are applied
to CH2.
*
The cooling capacity is the sum of the capacities of CH1 and CH2.
*
The ambient temperature of 32
°
C is at 60% fan output (default setting).
*
The ambient temperatures of 40
°
C and 45
°
C are at 100% fan output. (The noise level rises by approx. 3 dB(A) from the rated condition.)
Mechanical Seal Pump
The pump used for the thermo-chiller HRLE090 series uses a
mechanical seal with the fixed ring and rotary ring used for the
shaft seal part. If foreign matter enter the gap between the
seals, this may cause a trouble such as leakage from the seal
part or pump lock. Therefore, it is strongly recommended to
install the particle filter in the return piping of the chiller.
