INDUSTRIAL DEHUMIDIFIERS
Expansion valve
Evaporator
Humid air
- The dehumidifier uses a refrigeration cycle.
- Humid air is cooled by the evaporator and liquid is condensed;
the liquid waste water is then removed so that the air is dehumidified.
- The cooled air is heated by the reheater, reducing the humidity of the air
which is blown out of the dehumidifier.
- Room temperatures can be prevented from rising by selecting reheating
and cooling types with outdoor units.

FEATURES
REDUCED ENERGY CONSUMPTION
(inverter-equipped) < Reheating only type >
Inverter control allows the unit to be used under a wide range of dehumidification load conditions as well as reducing
energy consumption.
It also makes it possible to reach the set humidity level within a shorter time and to respond to a greater fluctuation of
dehumidification load.
Depending on the fluctuation of the dehumidification load, the compressor speed is controlled by the inverter to
adjust the dehumidification capacity. Compared to the constant speed type, power consumption is reduced as the
unit runs more efficiently for the set humidity level.

Note:
1. The performance indicates the values for the operation under the conditions: Indoor air inlet
temperature 25°C, indoor air inlet humidity 80%, strong wind, and nominal operation.
The maximum indicates the maximum value with the inverter.
2. For wiring installation work, allow about 1.2 times of the electric properties.
3. In reheat mode, the air outlet temperature is higher than the air inlet temperature.
The temperature rises approximately 10 to 25°C, depending on the operating conditions.
If the temperature rise is a problem, consider installing separate air conditioning or ventilation.
4. Operational noise is measured in an echo-free anechoic room at a position 1.0m away from the
front air outlet and a height of 1.0m and converted into A-scale values. In the actual operation
after installation, noise normally becomes larger due to ambient noises and echoes.
The operational noise indicates 1/3 octave band noise at low air volume setting.
This unit is equipped with an inverter.Compared to the constant speed model, it generates a high
frequency sound unique to inverters, which is normal.The tone is different from the constant
speed model. Be careful when selecting the installation environment and location.
5. The unit is controlled based on the temperature and humidity detected by the front temperature
and humidity sensors. The data may differ from the ambient humidity or the temperature/
humidity of the heat exchanger air inlet.

Note:
1. Reheat dehumidification capacity and electrical characteristics indicate the data when the
unit runs under the conditions : Air inlet temperature 25°C and Air inlet humidity : 80%.
The maximum indicates the maximum value with the inverter.
2. Operational noise is measured in an echo-free place at a position 1.0m away from the unit
front and a height of 1.0m and converted into A-scale values.In the actual operation after
installation, noise normally becomes larger due to ambient noises and echoes.
3. In reheat mode, the air outlet t emperature is higher than the air inlet temperature.
The temperature rises approximately 10 to 25°C, depending on the operating conditions.
If the temperature rise is a problem, consider installing separate air conditioning or
ventilation.

Note:
1. The reheat dehumidification capacity and electrical characteristics indicate the values for
the operation under the conditions: Air inlet temperature 25°C and indoor air inlet
humidity 80%.
2. The cooling dehumidification capacity and electrical characteristics indicate the values for
the operation under the conditions: Air inlet temperature 25°C, indoor air inlet humidity
80%, and outdoor air inlet temperature 30°C.
3. The maximum indicates the maximum value with the inverter.
4. Operational noise is measured in an echo-free place at a position 1.0m away from the unit
front and a height of 1.0m and converted into A-scale values.In the actual operation after
installation, noise normally becomes larger due to ambient noises and echoes.
5. In reheat mode, the air outlet temperature is higher than the air inlet temperature. The
temperature rises approximately 10 to 25℃, depending on the operating conditions. If the
temperature rise is a problem, consider installing separate air conditioning or ventilation.
6. The standard length of the piping between the indoor unit and the outdoor unit is 5.0m
(one way). The performance (dehumidification capacity, etc.) shown in the table is for
installation with the 5.0m one-way piping laid horizontally.
7. If the unit is operated in a room with a low load such as a small greenhouse, reheat mode
and cooling mode will alternate frequently, resulting in malfunction. In this case, consider
adding ventilation or extra load to keep the alternating frequency at twice per hour or less.
8. As the blower is directly connected to the motor, air volume changes depending on the
static pressure outside the unit.
9. For wiring installation work, allow about 1.2 times of the electric properties.

Note:
1. The reheat dehumidification capacity and electrical characteristics indicate the values for
the operation under the conditions: Air inlet temperature 25°C and indoor air inlet
humidity 80%.
2. The cooling dehumidification capacity and electrical characteristics indicate the values for
the operation under the conditions: Air inlet temperature 25°C, indoor air inlet humidity
80%, and outdoor air inlet temperature 30°C.
3. The maximum indicates the maximum value with the inverter.
4. Operational noise is measured in an echo-free place at a position 1.0m away from the unit
front and a height of 1.0m and converted into A-scale values.In the actual operation after
installation, noise normally becomes larger due to ambient noises and echoes.
5. In reheat mode, the air outlet temperature is higher than the air inlet temperature.The
temperature rises approximately 10 to 25°C, depending on the operating conditions. If the
temperature rise is a problem, consider installing separate air conditioning or ventilation.
6. The standard length of the piping between the indoor unit and the outdoor unit is 5.0m
(one way).The performance (dehumidification capacity, etc.) shown in the table is for
installation with the 5.0m one-way piping laid horizontally.
7. If the unit is operated in a room with a low load such as a small greenhouse, reheat mode
and cooling mode will alternate frequently, resulting in malfunction.In this case, consider
adding ventilation or extra load to keep the alternating frequency at twice per hour or less.
8. As the blower is directly connected to the motor, air volume changes depending on the
static pressure outside the unit.
9. For wiring installation work, allow about 1.2 times of the electric properties.

Note:
1. The diagram shows the values when a dehumidifier inverter with the above
capacity runs at maximum frequency.The "●" in the diagram indicates the
maximum capacity for standard operating conditions: Air inlet temperature 25°C,
indoor air inlet humidity 80%, and outdoor air inlet temperature 30°C.
2. The diagram indicates the data without capacity drop due to frosting.
3. The dehumidification capacity in the diagram indicates the capacity when the
outdoor air inlet temperature is 30°C. The dehumidification capacity at a different
outdoor air inlet temperature can be obtained by multiplying the value by the
correction coefficient in the table below.

*1. The direct blow plenum chamber and duct chamber for round duct connection are shipped as assembled.
*2. When the direct blow plenum chamber and duct chamber for round duct connection (excluding the flexible
duct) are installed, the product height will be 250mm higher. Be careful about this.
*3. When installed, the air volume will decrease and the dehumidification capacity will decline. Be careful
when choosing a model.
*4. A high efficiency filter and deodorant air filter cannot be installed simultaneously.
*5. All filters require an optional filter box. Separate arrangement is required.
*6. The filter is not included. Separate arrangement is required.
*7. A closing plate to shield the front side is included.
*8. Long life filter (with antibacterial treatment), high efficiency filter and deodorant air filter cannot be
installed simultaneously. Any filter needs the filter box, which is optional. Separate arrangement is required.
*9. The filter box for the indoor unit and the front suction and the duct box for the rear suction are not airtight.
A small amount of air is sucked in through the gaps.
*10. As a guide, maintenance should be performed every 2,500 hours.(For libraries and museums. The length of
time varies depending on the use conditions.)
P.45
*11. Antibacterial treatment: ○ Testing organization: Boken Quality Evaluation Institute. ○ Test report: 029718
○ Test method: Based on JIS L 1902. ○ Antibacterial activity value: 5.3 for long life filter and 5.4 for high
efficiency filter. ○ Test result: Effective (JIS Z 2801)
*12. Deodorant air filter:
(1) Effective for acetic acid, acetaldehyde, and ammonia
(2) Dust collection efficiency by gravimetric method 50%
○ Test method: The test piece (100 x 100mm) is placed in a Tedlar® bag and deodorization performance is
tested for various odor components.(The filter is not capable of suppressing odor itself.The toxic substance
(carbon monoxide) contained in cigarettes cannot be removed.)
*13. The cover is used when the unit is remotely controlled after the control section has been removed from the
indoor unit.The cable should be prepared locally.Use the twisted-pair cable (KPEV, KPEV-S, or equivalent)
of 0.75mm2 or greater.
*14. The cover is used to cover the hole in the indoor unit when the control switch is moved to another location.
*15. The duct chamber for a round duct connection comes with a 200 flexible duct (length 600mm) and
installation band. (The flexible duct is not self-supporting. Note that it may sag under its own weight.)
*16. This is used to extract input/output signals from the PCB in the indoor unit.

Pressure Loss Characteristic Curve(Initial Pressure Loss)
Note:
1. Create a straight section for the suction duct using a canvas duct, for example.
2. Filters are not included.
3. When a filter is installed, air volume will decrease and the dehumidification capacity drops. Be careful when you choose a model.
4. Antibacterial long-life air filter (sold separately), deodorant air filter, and high efficiency filter cannot be installed simultaneously.
5. Filters can be removed or installed from either side of the duct set for rear suction.
Service space of 900mm or more is required on the right or left side of the indoor unit.

*2. Dust collection efficiency is based on general airborne dust
(dust concentration 0.15mg/m3). It does not indicate the odor absorption efficiency.
*3. To reuse the filter, dry it in the sun for nearly a day to release the absorbed odor
into the atmosphere.
*4. Rinse with water for cleaning. (Detergent reduces absorbing performance.)
*5. Test piece (100x100mm) is placed in a Tedlar® bag and deodorization performance
is tested for various odor components. The filter is not capable of suppressing odor
itself.The toxic substance (carbon monoxide) contained in cigarettes cannot be
removed.
