Ion Exchange Resin Purifying Equipment
For Circulating Water Systems
When installed as a bypass circuit within the chilled water circulation circuit, it can prevent rises in electrical condeuctly in the circulating water.

hose nipple, hose band
tee coupling, nipple, hose

Processing capacity figure based on water source standard purity level of 150μS/cm. Capasity may vary according to water quality.
Processing capacity is not based on circulating water flow system. Ion exchange resin lifespan and water quality may fluctuate depending on the properties of the wetted parts and suefaces, as well as the particular working environment.
It is recommended that the initially supplied water be either water that has been purified by having passed ehrough an ion exchange resin, or be commercially purchased deionized water. If tap water (or a similar grade of water) is used, the effective life of the ion exchange resin will be greatly reduced. In this case, please replace the ion exchange resin with the apare soon. (Ion exchange resin assemblies A, B, C, and F only.)
Ion exchange resin assemblies D and E are wall mounted. Please confirm that there is a suitable installation place before installing the filter. A stand mount is available as an accessory (sold separately). (The mounting hole positions of Ion Exchange Resin D and E assemblies are the same as the mounting hole positions on Water Filter A and B assemblies respectively. Please refer to the Water Filter Equipment page for details regarding dimensions.)
on Ion Exchange Resin D and E assemblies, if there is a chance that the water pressure within the purification vessel will exceed 0.2MPa, a pressure reducing valve should be installed.
Avoid installing the ion exchange resin where it will be in direct sunlight or in places where there is a risk of it being damaged.
For Water Supply and Purification
Can suppress sharp rises in electrical conductivity of circulating water that occurs when supplying water to the water tank.

If there is a chance that the water pressure within the vessel will exceed 0.34MPa, a pressure reducing valve should be installed.
Avoid installation of the deionizer where it will be in direct sunlight or in place where there is a risk of it being damaged.
Remote Control (Wired)
Remote Control Sets include cables. Tha set model number differs depending on the cable length. (Max cable length: 20m, 50m, 100m.)
At time when the liquid temperature is rising, the heater should be used if high-precision control is required even when the load is low (and there is not the minimum amount of heat required for inverter control).
Discharge Pump for High Head Applications
High flow rate pump built-in. A built-in pump supporting a higher head specification is available.
Cleanroom (Leakage Alarm Spec.)
Leakage Alarm Spec. models are available for use in cleanrooms.
Leakage Detection Spec.
If for some reason a water leak occurs, an alarm will be activated.
Please see the "Equipment (Standard / Optional) List" below for details.
