Simple operation
Heat source
Temperature sensor
This function adjusts the fl uid temperature 
to the set value with an automatic offset 
setting. Set the external temperature 
sensor at the circulating fl uid inlet located 
just in front of the heat source, which 
allows the thermo-con to sample the fl uid 
temperature. This function is effective 
when automatically adjusting for heat 
exhaust from piping etc.
Less vibration and noise 
with no moving parts such 
as a compressor. For HECR 
004/006/008/010, noise is 
reduced by suppressing the 
number of fan rotations 
when the cooling load is 
low.
If the external temperature sensor is installed directly on the heat source, the learning control 
function may not work property due to large heat volume or large temperature difference. Be sure 
to install the sensor at the circulating fl uid inlet.
Circulating fl uid volume can be checked.
q Turn the power ON.
w Press the 
SEL
 key, and adjust the temperature 
setting with the 
 keys.
e Press the 
RET
 key to complete.
Can precisely control the temperature of a heat source or process fluid.
Precisely control the temperature of the circulating fluid by using the Peltier device.
Refrigerant-free and environmentally friendly.
Learning control function (Temperature control by external temperature sensor)
Low vibration, Low noise
Drain pan
Drain pan is equipped to avoid any 
risk of fl uid leakage over equipment 
mounted in a lower rack.
Fluid fi ll port
Fluid can be supplied 
without removing the 
product from the rack.
Power switch
Rack mounting 
bracket
Floor type is also available. (Option)
The rack mounting brackets and the handles can be removed and 
rubber feet can be mounted instead. (Refer to page 19 for details.)
