1 General Information 1.1 Foreword This manual is designed to serve as the installation, operation, and maintenance guide for your dryer system. The contents of this manual should be carefully read BEFORE attempting any phase of installation, operation or maintenance. Failure to follow the operating and maintenance procedures of the instruction manual could result in personal injury or property damage.
1.2.3 Automatic Drain Valves As previously stated, the accumulated water and oil mixture collected by a prefilter must be periodically drained from the prefilter housing sump. A Deltech Automatic Drain Valve is a recommended and reliable means of removing collected moisture, oil and sludge from coalescing prefilter housings and other components requiring periodic draining. 1.2.4 Afterfilter Assembly The Deltech D-Series Particulate Afterfilter Assembly is another feature offered.
2 Installation 2.1 Receiving and Inspection Immediately upon receipt of the dryer, thoroughly inspect for damage that may have occurred during shipment. Since the dryer is shipped F.O.B. Ocala, Florida, the carrier is legally responsible for damage incurred during shipping. Shipping damage is not covered by the dryer warranty. If goods are received short or damaged, notify the carrier and insist on a notation of the loss on the face of the bill of lading.
2.4 NOTE 1: NOTE 2: NOTE 3: NOTE 4: NOTE 5: NOTE 6: 1. 2. 2-2 Table 2.1 CONNECTIONS General Piping Information Use the proper pressure rated piping, fittings and valves as approved by ASME, ANSI, ASA, etc. Separate or special requirements by local and/or municipal codes may also apply. Model The manufacturer is not liable for code violations, downtime, component failure or consequential damages to customer supplied components and/or equipment.
2.7 PREFILTER AIR INLET BLOCK VALVE Electrical Connection NOTE 1: Use proper, load-rated components as approved by NEC, NEMA, CSA, UL, etc., as required. Local and municipal codes may also apply. All installations and connections must be in accordance with recognized electrical codes in effect. NOTE 2: It is mandatory that each dryer be individually GROUNDED. Do not use your plant’s frame as a ground. Use an adequate ground with the conductor sized to NEC.
CAUTION STATIC SENSITIVE DEVICES STATIC SENSITIVE DEVICES CAN BE DAMAGED BY ELECTROSTATIC DISCHARGE. YOU CAN MINIMIZE THE CHANCES OF DESTROYING SUCH DEVICES BY: 1. KNOWING THAT THERE IS A POTENTIAL STATIC SENSITIVE PROBLEM. 2. ADHERING TO THE GUIDELINES LISTED BELOW FOR HANDLING THEM. 3. USING RECOMMENDED PACKAGING AND BENCH TECHNIQUES. FOLLOW THESE PRACTICES TO MINIMIZE DAMAGE TO STATIC SENSITIVE DEVICES. 1. DO NOT WELD ON THIS EQUIPMENT AND/OR ASSOCIATED PIPING.
CAUTION: Surges, spikes and input voltage of less than eighty-five (85) VAC or greater than one hundred and thirty-two (132) VAC, may cause the Dryer Control System to operate erratically, or malfunction. This malfunction may or may not be accompanied by an alarm. Adequate surge, spike, brownout, and blackout protection must be provided to protect your equipment and allow safe shutdown time (an uninterrupted power supply is recommended).
b) Close the dryer control system enclosure cover and tighten all cover latches. CAUTION: Do not remove the factory programmed microcomputer chip or any I.C. chip from the logic control circuit board. Improper removal will cause irreparable damage to these highly static-sensitive components. Damage to these components will render the dryer control system inoperative until replacement is accomplished by a Deltech Field Service Engineer.
When the Energy Management System LED indicator is OFF, the dryer either does not have the Compu-Save Energy Management System option, or that the sensor has determined that the relative humidity in the on-line chamber has reached the predetermined set point. At next switchover, that chamber will regenerate using purge air. When the Energy Management System LED indicator is flashing, a high humidity condition may exist or there is an Energy Management System failure.
3 Operation 3.1 How It Works Incoming air or gas is first passed through the system prefilter to remove liquid water and oil contaminants. The dryer then removes vaporous contaminants. The dryer's cycle control system alternately cycles the compressed gas flow through the unit's twin desiccant chambers. As the vapor-laden gas supply enters and flows downward through a desiccant chamber, the contaminant vapors are attracted to and adsorbed on the surface of the activated desiccant.
Do not start the dryer with compressed air flow through the dryer. Close customer supplied dryer shut-off valves before beginning start-up procedure. 1. Refer to the General Arrangement drawing as necessary for component identification and location while conducting start-up and operational procedures. Note: If your dryer cannot be started, or fails to start due to special installation or other problems, contact your local Deltech Sales Representative for assistance. 2. 3.
Afterfilter cartridges are NOT interchangeable and must be installed in their respective assemblies ONLY. The proper filter cartridge part number is listed on each Prefilter and Afterfilter Assembly. 15. Refer to Appendix A (Appendix C for -100°F pdp) of this manual and calculate your dryer model's purge pressure setting as instructed. 16. Locate the Purge Adjusting Valve. Slowly rotate dryer’s Purge Adjusting Valve until the Purge Pressure Indicator indicates the calculated purge pressure setting.
IMPORTANT: Water molecules can diffuse through a pinhole-size leak even though pressure inside the piping is several hundred PSIG. It is not uncommon to have a minute pinhole leak in a gas line cause an increase in dew point from -40°F to -10°F at a distance of forty or more feet downstream of the leak. 12. SLOWLY open the customer-supplied System Outlet Isolation Valve, while monitoring the Outlet Pressure Gauge (if dryer so-equipped).
right chamber. Both Purge Exhaust Switching Valves will close. The desiccant chambers will immediately begin pressurizing to system pressure as indicated by chamber pressure gauges. For dryers with the Hydrobloc Energy Management System: During operation in the Energy Management Mode, the off-stream chamber may remain pressurized (in ENERGY MANAGEMENT ACTIVE). If this condition is noted, proceed as follows to adjust purge pressure. 10.
5. Close any manual vent or drain valves installed in prefilter and afterfilter assemblies. 6. If the prefilter assembly utilized was factoryequipped with an automatic drain valve or drain trap, inspect for, and remove pipe plug or cap which may have been installed in drain port for shipping purposes. 7. Ensure that all associated pipe and tubing connections, flanges, unions, plugs, mounting bolts, pipe hangers, etc., have been checked tight and/or properly secured.

HYDROBLOC LSC PURGE CURVES Calculation of Purge Pressure Setting 1. Determine air pressure (psig) at the dryer inlet. 2. Refer to Table C-1. Determine the inlet airflow for your model and inlet air pressure. 3. To calculate purge flow consumption on the critical orifice curve: Inlet Flow (SCFM) × 14.7 PSIG Inlet Pressure (PSIG) + 14.7 PSIG 6. Note: The purge pressure can only be read and adjusted when an off-line desiccant chamber has depressurized for regeneration.
