How the HDC-2400 Silo Dust Collector Works

The HDC-2400 Silo Dust Collector captures airborne dust and vents displaced air during pneumatic filling of cement and other bulk material storage silos. Its automatic pulse-jet cleaning system helps maintain airflow through the filter cartridges, supporting efficient dust collection and helping prevent excessive pressure buildup during filling.

Automatic Pulse-Jet Filter Cleaning

As bulk material enters the silo, displaced air passes through the dust collector’s filter cartridges. The cartridges capture airborne dust while allowing filtered air to escape.

As dust accumulates on the filter surfaces, resistance to airflow increases. A differential pressure switch monitors pressure inside the dust collector relative to atmospheric pressure. When pressure reaches the designated setpoint, the automatic cleaning system initiates alternating pulses of compressed air through the cartridge purge lines. These pulses dislodge accumulated dust, allowing it to fall back into the silo and helping maintain filter performance.

Integrated Compressed Air Receiver

The HDC-2400 features a built-in compressed air receiver that supplies the automatic pulse-jet cleaning system. This integrated design eliminates the need for a separate external receiver tank, simplifying the installation.

Weather-Resistant Filter Housing

An overhanging lid helps protect the filter housing from rain and other environmental debris while allowing filtered air to discharge to the atmosphere.

Convenient Filter Service Access

The top-opening service hatch provides convenient access to the filter cartridges for inspection and replacement. A spring-assisted mechanism helps support the lid during opening and closing, while a locking mechanism holds the lid securely in the open position during maintenance. A breakover latch with retaining pin secures the hatch when closed.

An internal spring-loaded assembly also helps retain the filter cartridges in their proper position.

Replaceable Filter Cartridges

Replacement filter cartridges are available directly from Hess Services, providing customers with a convenient source for replacement components and ongoing maintenance support.

Designed for New or Existing Silos

The HDC-2400 can be supplied for installation on new silo projects or retrofitted to compatible existing silos. Hess Services also offers a proprietary weld-in mounting flange separately for customers looking to install the HDC-2400 on silos manufactured by other fabricators.

Installation Requirements

The HDC-2400 requires customer-supplied electrical power and a compressed air supply. Field wiring and external piping are by others. The collector includes a 1/2-inch compressed air supply connection and a 1/2-inch drain connection.

Replacement Filters for the HDC-2400

Replacement filter cartridges are available for the Hess Services HDC-2400 dust collector.
