0. Introduction & Promising Effects''Humidity control'' is the essential requirement for static or moisture issues and stable operation in textile industries.Because moderate humidity provides ideal environment so that static electricity hardly generate and moisuture without wetting.Ikeuchi's AirAKI Dry Fog Humidification System will provide uniform stable humidity.Ikeuchi would like to offer the following proposal for your benefits of productivity, quality.

1. Conditions

Approx. Volume [m3] 49,896

Measurement [m] 84 x 108 x 5.5

Target Temp. & Humidity 70%RH at 22 deg C

Worst Temp & Humidity -

Supply Air [m3/hr] N/AWorst Outside Air Conditions 8 deg C, 50% RH

Absolude humidity [kg/kg (DA)] 0.0033

Outside Air Induction [m3/hr] * 49,896

Ventilation rate [times/hr] * 1.0

* We assumed these numbers.

2. Humidity CalculationOur humidity calculation resulted 178 nozzles at least would be required to get the target humidityconsidering the above air conditions.

Target Humidity

70% RH at 22deg C Desired Humidity [LPH] 497

Absolude humidity [kg/kg (DA)] Desired Humidity [GPH] 131

Quantity of Nozzles(Calculation Result)

if only 6,003LPM at 0.3MPa air can besupplied. 207

0.0116

Quantity of Nozzles(Calculation Result)

if 5,934LPM at 0.5MPa air can besupplied. 138

3. Humidification System Layout and UtilityWe would like to propose our humidification system using 140 nozzles considering layout balance. Please check the utility below and the attached system layout.

Refer to the attached layout and ''Break-down of Dry Fog Humidification System Proposal''.

Option: Quote No.901204This is the quote of humidifiers only without controller when you prepare humidity controllers, solenoid valve units, humidity sensors by yourself.

3) Supply by customer or third-party contractorQuantity Remarks

Plumbing and InstallationStainless steel pipes, valves and fittingsPlumbing, Components installation 1pkg.Power distribution works, Pipe flushing before system start-up

General Installation manualto be provided by IKEUCHI.

You may need some stop plugs to adjust spray nozzlenumbers or when you maintain nozzles.

Pressure: 0.3 - 0.35 MPa (44-51PSI) at a point of useTemperature: 5 deg C (41 deg F) - Normal temperatureQuality: Air without moisture, oil mist and dust; Dew point 10 deg C (= 50 degF)Purifying Devices: Air Dryer, Air Filter, Oil Filter

* Air Filter - Remove foreign particles of over 5 micro meter.Oil Filter - Remove foreign particles of over 0.03 micro meter.

Air Heater: Place an air heater when the humidifier is operated in low ambient temperature orwhen the compressed air temperature becomes lower than 12 degC (=54 degF)* Apply thermal insulator to air pipe after the point of an air heater.

Pressure: 0.1 - 0.15 MPa (15 - 22PSI) at a point of useTemperature: Normal temperatureQuality: No particles

Electric Conductivity = 0.07 - 10 microsiemens/cm(Resistance 14 - 0.1 M ohm/cm )Silica ( SiO2) = 5ppm or less

Total Hardness + Bicarbonate = 60 ppm or lessPurifying Devices: Y Strainer(0.1mm), Water Filiter (5 micrometer), Water softner

Reverse Osmosis Water Purifier, Ion Exchange Water Purifier* Water Softener and Reverse Osmosis Water Purifier produce continuousdischarged water during their operation. Provide drainage basin.

Remarks4 nozzles mounted.Inelt connections of air and water are 1/4'' NPT femalethread. Refernce drawing and image of intallation areattached.

5. Typical System Flow

We will supply No. 1 - 4.Please check No. 5 - 9 (10) & No. 11 - 17 are already installed.

6. Maintenance

Daily check- Spray pattern of Humidifiers- Air pressure and water pressure- Drain water volume of air filter- ON/OFF control by the solenoid valve and the cotroller is working correctlyPeriodicalMaintain air compressor, reverese osmosis system and deionizer regulary

Off-seasonDrain water in pipe, water tank when you don't use the system over a few days in summer time, 1 week in winter time.
