Over the years, Panblast has developed many customized solutions for customers when its extensive range of standard products does not fully meet specific application requirements. Recently, the company decided to publish an Engineered Products Catalog to more effectively illustrate the wide variety of customized solutions possible. While the catalog itself contains many more categories and products, some of the more popular product categories include:

• DHS Summer Dehumidifier Series

• VTS Portable Skid-Mounted Dust Collectors

• RCE Retractable Concertina Containment Enclosures

• Bulk Blast Pot Abrasive Recycling & Loading Systems

• Waffle Floor Pneumatic Abrasive Recovery Systems

The DHS Summer Dehumidifier Series is designed and engineered for humid ambient temperatures ranging from plus 22 to plus 38 degrees Celsius, delivering dehumidified air at 25 degrees Celsius and a relative humidity below 45% to the designated enclosure. The use of durable and corrosion-resistant materials during construction ensures years of trouble-free usage in harsh marine environments, such as shipyard applications.

The DHS Summer Dehumidifier uses a compressor-style dehumidification process to remove moisture from warmer climates or for use during the summer season. Moisture-laden air is drawn from the atmosphere into the unit across the evaporator refrigerant condensing coils to condense and remove moisture from the air, with the extracted water dripping to a drain (stainless steel drain pan optional). The moisture-free air is then reheated and fed back into the designated enclosure as dry, cool air, thereby reducing the relative humidity within the enclosure.

Dehumidification, or removing moisture from the air to control the environment during blasting and painting, helps prevent flash rusting and promotes the curing of coatings. The surface of the blasted substrate must be 3 degrees Celsius or higher than the dew point to prevent moisture from condensing on the substrate. Moisture condensing on an abrasive-blasted surface can cause problems with paint primer adhesion and also affect coating cure. Dehumidification can also be used to speed up drying of concrete and hydroblasted surfaces prior to painting.

The VTS Portable Dust Collector Series comprises rugged, self-contained dust collection units specifically designed for on-site applications in the abrasive blasting industry. All models in the VTS series are compactly designed for full mobility around the blasting site and are available in various capacities and flow rates ranging from 5,000 m³/hour to 20,000 m³/hour.

The system is supplied as standard with a 15-meter-long electrical cable and plug. Upon receipt, a few simple steps are required for site setup as follows:

1. Unpacking of the system

2. Positioning of the portable dust collector and fitting of the 4 x telescopic extension legs and fines/dust waste drum

3. Supplying compressed air for the reverse pulse jet cleaning system

4. Fitting of the optional flexible exhaust ducting from the VTS unit to the enclosure requiring dust ventilation

All VTS portable dust collectors are reverse air jet pulse-type units featuring pleated jumbo filter cartridges. A reverse air jet pulse purging system is used to clean the cartridges periodically by pulsing a charge of compressed air inside the filter cartridges, dislodging excessive dust buildup.

Retractable Concertina Containment Enclosures are ideal for blasting and/or painting operations and are designed to collapse and extend to facilitate loading and unloading of workpieces. This also allows the floor space to be used for other tasks when the enclosure is not in use. To extend and retract the enclosure, an optional drive system can be provided with wireless remote control. When retracted, the room length will be approximately one-third of its original length.

The enclosure consists of steel frames mounted on heavy-duty casters, with fire-retardant fabric attached to the structure. To protect the fabric, replaceable 3 mm thick rubber sheets are hung in strips to protect the entire internal surface of the containment enclosure.

Illumination is provided by evenly spaced LED lighting modules mounted to the walls. A suitably sized ventilation dust collector system is supplied with each enclosure. These dust collectors feature cartridge filters with automatic reverse air pulse jet cleaning.

An emergency escape panel is provided on one side of the enclosure. The enclosure is suitable for outdoor installation and is designed for moderate wind speeds up to 32 km/h (20 mph). Suitable tie-down points are provided to attach the enclosure to the floor foundation using guy lines.

Bulk Blast Pot Recycling & Loading Systems are designed for loading and recycling recyclable abrasive media such as garnet, aluminum oxide, glass beads, and steel abrasives into the abrasive storage hopper, which then feeds the abrasives into optionally supplied two, three, or four BP600 Pressure Blast Pots, or a single BB120 Bulk Blast Pot. The storage hoppers are sized based on storage capacity requirements.

The unit is typically mounted in a pit (pit-less installation options are available) with a sweep-in type feed hopper at floor level. A flow control shedder plate in the feed hopper regulates the flow of abrasive media to the boot of the bucket elevator. The media is then lifted via buckets fastened to the elevator belt and fed into the abrasive recycling system.

A horizontal screw conveyor transports the media to a rotary sieve, where oversized particles are separated into a drum via a flexible collection pipe. Reusable abrasive media falls through the sieve to an air wash separator, where dust and fines are removed and directed to waste drums. An adjustable damper allows the system to accommodate different abrasive types and controls particle size distribution of the working mix. Airflow for the system is generated by a filter cartridge dust collector with automatic reverse pulse jet cleaning.

The cleaned abrasive mix flows down into the storage hopper located below the recycling unit and above the blast pots. Optional level sensors (standard for bulk systems) monitor media levels and alert the control panel when full. If the blast pots are also equipped with level sensors, these can be interlocked with the hopper sensors for automatic refilling control.

Waffle Floor Recovery Systems operate successfully with all common abrasive media types, including metallic grits and shot, garnet, glass beads, aluminum oxide, plastic media, and organic materials such as nutshell and corn cob.

The waffle floor module is fabricated from mild steel plate with pre-cut abrasive feed slots. High-velocity air is drawn through the center duct along the length of the module. As abrasive media falls into individual hoppers and through the slots, it is pneumatically conveyed to the adjustable cyclonic reclaimer assembly. A steel floor grid is installed above all modules for walkability and to prevent debris from entering the recovery hoppers.

The media is conveyed to the reclaimer by either fabricated ducting or heavy-duty suction hose. The reclaimer separates dust and fines from usable media while a debris screen captures oversized particles.

Waffle floor modules are available in three standard widths: 600 mm, 1000 mm, and 1500 mm. Common layouts include single, twin, or triple modules, often placed along side walls for optimal collection. Systems requiring trolleys and tracks typically use three modules, with one placed between the tracks.

For fully automated recovery, the entire floor can be covered with waffle modules so that abrasive media is recovered immediately after blasting. Any necessary equipment, such as tracks, can be placed between or above the modules, which are capable of supporting heavy loads.

Panblast is uniquely positioned in the global blast cleaning industry and continues to advance with innovative product designs and engineered solutions tailored to customer requirements.
