• DO NOT OPERATE THIS SYSTEM ABOVE MAXIMUM WORKING PRESSURE (MWP) AND/OR MAXIMUM OPERATING TEMPERATURE (OF) SHOWN ON THE VESSEL ASME DATAPLATE. THIS ASME CODE VESSEL MUST BE PROTECTED BY A PRESSURE RELIEF VALVE. Refer to OSHA 1910.169 Par. b, Sub. Par (3) and ASME Boiler and Pressure Vessel Code, Section VIII, Division 1, UG-125 through UG-136. Also comply with all applicable provincial, state and local codes.

• DO NOT ATTEMPT TO REMOVE OR REPAIR ANY PART OF THE SYSTEM UNTIL IT IS COMPLETELY DEPRESSURIZED. SERIOUS PERSONAL INJURY OR DEATH MAY RESULT IF THIS RULE IS NOT FOLLOWED.

• DO NOT WELD OR GRIND ON VESSEL, THIS WILL MAKE IT UNSAFE TO USE. (Note: Any alteration to the vessel will void the ASME Code Certification and the warranty.)

• INSPECT THE VESSEL, INSIDE AND OUT, REGULARLY FOR CORROSION, DENTS, GOUGES OR LEAKS. IF DAMAGED, REMOVE FROM SERVICE IMMEDIATELY.

• DO NOT TRY TO TIGHTEN A LEAKING COVER. IMMEDIATELY SHUT OFF THE AIR SUPPLY AND DEPRESSURIZE THE SYSTEM.

• DO NOT ATTEMPT TO REMOVE THE FILL COVER UNTIL THE SYSTEM IS COMPLETELY DEPRESSURIZED. WHEN THE VESSEL PRESSURE IS REDUCED TO ZERO, THE FILL COVER CAN BE REMOVED BY HAND. INSTALL A NEW GASKET AT LEAST ONCE PER YEAR. INSPECT THE FILL COVER AND SEALING SURFACE FOR DAMAGE SUCH AS CORROSION, CRACKS, OR DISTORTION. IF THERE IS ANY DAMAGE, REPLACE THE FILL COVER. REPLACE THE FILL COVER EVERY FOUR YEARS REGARDLESS OF CONDITION.

• USE MOD-U-BLAST AUTHORIZED PARTS ONLY.

• DO NOT USE POWER TOOLS TO TIGHTEN THE NUT ON THE FILL COVER. TOO MUCH FORCE CAN DISTORT THE FILL COVER AND/OR THE GASKET. IF DAM-AGED BY OVER-TIGHTENING, THE FILL COVER CAN BLOW OUT AND CAUSE SERIOUS INJURY OR DEATH. (Note: Tighten the nut until it is snug. When the vessel is pressurized, the pres-sure on the fill cover will complete the seal.)

• THE USE OF PRODUCTS OTHER THAN MOD-U-BLAST® DESICCANT WILL VOID THE WARRANTY.

Important Warnings



DRY-PRO by MOD-U-BLAST® Single Tower, Deliquescent, Air Dryers are a skid mounted system which includes an aftercooler, a coalescing filter and a single tower dryer filled with desiccant tablets. Warm air enters the aftercooler where it is cooled close to the surrounding temperature, water is then condensed out during this cooling process. The saturated air and the liquid water pass through a coalescing filter where any oil contaminants from the com-pressor are removed and then proceeds to the inlet of the dryer tank. The water and any solid particles present are separated by gravity and fall to the bottom of the dryer tank. The air moves up through the desiccant tablets which absorb the moisture from the air before it flows through the dryer outlet. The tablets dissolve gradually as they absorb the moisture. The dissolved desiccant and water, falls into the bottom of the vessel. The dryer must be drained periodically to remove the accumulated solution. A manual ball valve is installed for this purpose.

How it Functions



DRY-PRO by MOD-U-BLAST® Vertical Dryers are rated as follows:250 CFM (DSV-250) - 450 CFM (DSV-450) - 750 CFM (DSV-750)- 900 CFM (DSV-1000) - 1200 CFM (DSV1200) - 1600 CFM (DSV-1600) at 100 PSI. Approach temperatures will vary with changes to the inlet conditions (flow, pressure, temperature) and the ambient temperature. The dew point out of the dryer tower is directly related to the inlet temperature entering the dryer vessel. The lower the inlet temperature, the lower the dew point of the outlet air.

Maximum Capacities for Dryer - CFM (Cubic Feet Per Minute)

The aftercooler maximum inlet temperature is 250° F. When using MOD-U-BLAST® desiccant, the inlet temperature to the dryer tow-

er should not exceed 100° F.

START UP PROCEDURES:Connect your compressor (fittings not included) to the DRY-PRO Vertical Dryer inlet, start compressor, then SLOWLY open the ball valve to pressurize the dryer. Make sure that the DRY-PRO Vertical Air Dryer is not subjected to sudden air surges. Always open the valves slowly to permit gradual air pressure between the Dryer and the compressor.

*Check that the regulator pressure is set as shown on cover page of this manual to maintain the fan speed rpm ensuring proper aftercooler performance.*

The DRY-PRO Vertical Air Dryer requires certain procedures to ensure best performance:

1. DAILY DRAININGThe desiccant and water solution in the bottom of the dryer should be drained often. The manual drain valve is installed on the dryer, must be opened at least once every 4 to 8 hours to drain the dryer. The dryer will require draining more often on humid days.

*If the dryer is not drained regularly, it may become flooded and the accumulated liquid WILL enter the air system.*

2. REFILLING THE DRYER WITH DESICCANTDuring the drying process, the desiccant tablets dissolve slowly. The desiccant consumption rate is dependent on several factors, such as inlet temperature, flow and pressure. To check the level of the desiccant, look into the sight window, if you can’t see the desiccant tablets then the tank has to be refilled to ensure peak dryer performance.



DESICCANT:See below for desiccant refilling.

LUBRICATOR OIL:Check oil level in lubricator regularly and add oil as required. (Automatic Transmission Fluid)

Operation

IMPORTANT !Our DRY-PRO by MOD-U-BLAST® Vertical Air Dry-ers are shipped WITHOUT the lubricator oil installed.

Lubricator oil (ATF) MUST BE INSTALLED before using the system.

FAILURE TO MAINTAIN OIL LEVEL WILL CAUSE THE FAN MOTOR TO SEIZE

IMPORTANT ! Our DRY-PRO by MOD-U-BLAST® Vertical Air Dryers are shipped with the desiccant installed. The desic-cant will NOT be installed if the unit is being shipped overseas at which point the proper amount of des-iccant will be shipped with the dryer and must be

installed before using the system.

Maintenance Procedures


CheCk DessiCant LeveLLook into the sight window, if the desiccant is not visible then top it off. Check the operation of all equip-ment installed before and after the DRY-PRO dryer.

Every 8 Hours of Use

CheCk OiL LeveL in LubriCatOrVerify that there is sufficient amount of oil in the lubricator and add oil as needed. ATF only (Automatic Transmission Fluid)


CLean afterCOOLer COreThe core should be cleaned regularly. Accumulation of dirt or oils will greatly reduce the efficiency of the aftercooler. Dirt can be removed by blowing the core off with compressed air. If the core becomes coated with oil particles, it can be steam cleaned.


aDDing DesiCCantShut down the air compressor and open the drain valve to allow the dryer to depressurize completely. Loosen the nut on the fill cover. Push on the fill cover. Once the seal is broken, remove the fill cover from the dryer. Add the amount of desiccant needed to restore to the maximum level.

COaLesCing fiLterCheck the condition of the oil removal filter element every 6 months and change annually. Some filters have a differential pressure indicator and when the RED button pops up in the indicator it is time to replace the element. When replacing the element make sure to clean and inspect the drain port.

Every 6 Months

fiLL COver inspeCtiOnInspect the fill cover and sealing surface. Should there be damage, replace the cover. Replace the fill cover every 4 years regardless of condition. The gasket should be replaced at least once a year.Check the sealing surface of the opening. If it has dirt or rust on it, then it must be cleaned before installing the fill cover.Install the fill cover and gasket. Tighten the nut on the fill cover until it is snug. Over tightening will cause damage gasket. The fill cover will seal when the vessel is pressurized.

Every 4 years

Procedure to be Performed Maintenance Interval

Maintenance Schedule

Danger: Never perform any maintenance or attempt to open the Vertical Dryer in any way while it is pressurized. The violent release of compressed air and propelled objects will cause serious injury or death.

Warning: Maintenance procedures are to be performed by experienced qualified personnel only, Failure to perform maintenance procedures correctly at the intervals specified below can lead to performance problems and equipment failure, and will void the equipment warranty.

Warning: Make sure the desiccant level is below the outlet pipe. Do NOT overfill the vessel. Space must be left to allow for the fill cover to be installed.
