Mr. Anderson
May 9, 2025

To place the Sahara Pak HC-1260 dryer in standby mode, the optional Dew Point Demand System (DPDS) must be installed. When DPDS is present, the STATUS screen will display "STANDBY" as part of the cycle. There are no specific steps provided for manually placing the dryer in standby mode.

An overhead clearance of not less than three feet above each tower is required for loading of the desiccant.

  • Page 8: Preventative Maintenance Prior To Start-Up

    INSTRUCTION MANUAL Model HC 1.0.1 Dryer Location and Mounting Specifications (continued) 1.0.1.12 For electrical connections, refer to the electrical drawing in Section 8. Be sure to look for any auxiliary connections, such as remote alarm contacts, compressor interlock relay (if needed), or analog (4-20mA) signals.

    INSTRUCTION MANUAL Model HC 1.0.3 Afterfilter 1.0.3.1 Use of a prefilter is not necessary, or recommended, with a heat-of-compression Model HC dryer. It is extremely important, however, that a afterfilter be provided in the dryer installation. The afterfilter eliminates the possibility of desiccant dust carryover into the instrument air system.

  • Page 11: Air Supply

    INSTRUCTION MANUAL Model HC 1.0.4 Air Supply 1.0.4.1 The air supply should be between 250F - 400F, and 100 PSIG - 125 PSIG compressed air. 1.0.4.2 In piping the air to the dryer, use a pipe size equal to or larger than the dryer line size, keep the length of piping as short as possible, and insulate the piping.

    "back flushing" to maintain performance. 1.0.7.2 The standard Sahara-Pak HC dryer is designed to use approximately 3.77 GPM per 100 SCFM of 85F cooling water. The air exiting the intercooler should be 95F or less as indicated by the temperature screen on the panel view.

  • Page 13: Start-Up

    INSTRUCTION MANUAL Model HC Start-up Prior to start-up: It is recommended that the operational program of the dryer and the wiring schematic be studied before operating the dryer. Desiccant level must be checked. Wear protective goggles and mask when working with desiccant. Reference Section 2 for desiccant instructions and Section 7 for the MSDS.

    INSTRUCTION MANUAL Model HC SECTION 2: OPERATION & MAINTENANCE Operation Never make any changes to the dryer that are not specifically authorized by Henderson Engineering Co., Inc. Only use original spare and accessory parts. Carry out maintenance work only when the dryer is switched off, depressurized (even though gauges may read 0, there may still be air in the dryer), and disconnected from the electric power supply.

  • Page 18: Description

    2.0.2 Description The Sahara-Pak HC dryer is a complete system consisting of the following major components: 2.0.2.1 Drying Vessels (insulation optional)
  • Page 19 2.0.2.4 Water-Cooled Intercooler, Separator, Dual Drain Trap The standard cooler used in the Sahara-Pak HC dryer is constructed of a carbon steel shell, tube sheets, baffles, and copper tubes. Reference the Specifications in Section 5 for the cooling water requirement.
  • Page 20 2.0.2.4 Water-Cooled Intercooler, Separator, Dual Drain Trap (continued) The Sahara-Pak HC dryer has a truly unique dual automatic drain system to remove the water from the separator. As the liquid level from the separator rises, the primary free float drain opens, discharging the accumulated water.
  • Page 21 2.0.2 Description (continued) 2.0.2.6 Control Group The complete operation of the Sahara-Pak HC dryer is fully automatic and pre-programmed to shift drying vessels continuously before the design water load can be reached (breakthrough). With the dew point demand system, the dryer will not switch towers until the drying tower is fully saturated.

  • Page 22: Theory Of Operation

    Heating Hot air directly from the compressor enters the inlet of the Sahara-Pak HC and is directed by the inlet 2-way valves into the regenerating tower. This hot, thirsty air regenerates the bulk of the water from the desiccant. The air is then directed...
  • Page 23 During stripping, a small adjustable flow of dry air is used to remove the last little bit of moisture from the regenerating tower. This allows the Sahara-Pak HC dryer to provide exceptionally low dew points. If lower dew points are required, then an optional booster heater may be required.
  • Page 24 INSTRUCTION MANUAL Model HC 2.0.3 Theory of Operation (continued) 2.0.3.3 Cooling At the end of stripping, the regenerating tower is repressurized. The cooling cycle valve opens (V13) and cooling begins. During cooling, a portion of the dry outlet air is directed into the regenerating tower to reduce the temperature of the bed prior to tower shift.

The SMT will measure either pressure or atmospheric dew points. For many applications, measuring pressure dew point may be more meaningful. 2. To measure pressure dew points, connect the supply line to the inlet of the sample cell.
  • Page 84 INSTRUCTION MANUAL Sahara Moisture Transmitter VII. Helpful Information (continued) 4. The probe is very rapid, is insensitive to temperature and flow rate and measures the vapor pressure of water only. If the above effects are noted, then they are almost always the result of the system itself and not the sensor.

    INSTALLATION INSTRUCTIONS CAUTION: COMPRESSED AIR CAN BE DANGEROUS The Robo Drain is designed for trouble-free and cannot be higher than the bottom of the vessel that maintenance-free draining of unwanted accumula- is being drained. It is best to run the drain in a tions of condensation and other foreign matter from downward pitch from the bottom of the vessel be- any collection point in a compressed air system...
  • Page 98 INSTALLATION DIAGRAMS IN GENERAL In order for the condensate to properly enter the Robo Drain reservoir, the condensate line to the Robo Drain must al- ways be installed below the bottom of the vessel to be drained. It is equally important to provide a means for the air that is contained in the reservoir to escape (vent) as the condensate enters the reservoir.
