In a previous post HERE, we explored the differences in CFD firehouse designs constructed under the Alive 21 initiative. The stations built include Engines 18, 38, 63, 70, 84, 88, 102, 121, Air/Sea Rescue, and Engine 109, which is still under construction. Notable variations among the designs included two similar models that differed in the presence of a hose tower, roof design, and the amount of glass used along the top of the apparatus bays. A third unique design is now being used for Engine 109’s new station and also for Engine 16’s new facility. Interestingly, Engine 16’s building marks what the City of Chicago Public Building Commission (PBC) refers to as the first “Prototype B†engine company house — though this seems a bit confusing since Engine 109 uses the same design.
Each firehouse has a different square footage depending on the specific needs of the unit it serves. For example, Engine 102’s station covers around 14,000 square feet, while Engine 121’s is larger at 18,000 square feet. These differences account for office space, meeting rooms, and training areas. Engine 16’s new station will be even bigger, at 18,500 square feet, including space for the Haz-mat unit, storage, and the EMS Field Division South offices.
The site sign for Engine 109’s new firehouse gives a glimpse of what's coming next. It’s an important symbol of progress and modernization for the department.
When the Alive 21 program started, the rear entry to the three apparatus bays had only two wide doors. This design was used for Engines 38, 63, 84, and 88. However, later changes introduced three single-width doors at the back, matching the front design. Stations for Engines 18, 70, 102, and 121 were built with this updated configuration.
Some of the newer stations have notable features like solar panels, landscaping, and unique architectural elements. For instance, Engine 121’s house includes large solar panels on the roof and a more open, grassy area near the driveway, setting it apart from others.
Hank Sajovic also noted that Engine 84’s station had its orientation changed during construction. While the watch room is on the east side, the apparatus exits to the west, making the "front" of the building feel reversed when viewed from the street. All stations are designed with the front on the left side when facing the flag poles, maintaining a consistent look across the city.
For those interested in following the progress of these projects, the Chicago Public Building Commission website provides links to completed stations and ongoing work. You can view galleries of photos documenting the construction of each facility.
Plastic Granulation Line
Plastic granulation production line is a production and processing machinery that converts plastic waste or raw materials into high-quality plastic granules.
1. PP/PE film granulation production line
It is suitable for processing a variety of raw materials, including plastic film, PP woven bags, cement bags, agricultural and greenhouse films, industrial packaging films, heat shrink films, stretch films, garbage bags and bubble films. The output range is 100-500 kg/h.
The production line includes crushing and cleaning machines, plastic film washing tanks, plastic dehydrators, plastic granulators, cooling tanks, granulators and storage silos. It produces high-quality recycled plastic granules with uniform size and excellent physical properties.
It is widely used in the manufacture of packaging materials, pipes, sheets and household items. The recycled granules are of high quality and can be directly used to produce new plastic products.
Flexible configuration, high granule quality, and customizable equipment to meet different customer needs.
Including crushing, cleaning, melt granulation, granulation and other processes to produce high-quality PVC granules.
PVC granulation line can produce high-quality PVC granules to meet the production needs of various PVC products. The production process is flexible to adjust, the production process is highly automated, and the granule quality is stable.
It is used for the production of PVC pipes, insulation materials, cable sheaths, etc., and has the characteristics of weather resistance and chemical corrosion resistance.
The equipment has a compact structure, small footprint, convenient installation and maintenance, and cost savings.
3. PET granulation line
Designed for PET material granulation, including PET waste such as broken bottles, with high output and low energy consumption.
The screw is designed according to the material characteristics to ensure that the produced granules have high output and good gloss. The twin-screw extruder unit is reasonably designed to increase output and reduce maintenance costs.
It is mainly used to recycle PET waste such as PET bottles and convert them into valuable resources for further processing.
High-quality electrical and drive equipment make the use of machinery and equipment safer and more reliable.
4. ABS/PC granulation production line
It is suitable for granulation of ABS, PS, PET, and ABS+PC materials. The production line has high output and low energy consumption.
The screw can be designed according to the material characteristics to ensure that the produced granules have high output and good gloss. The twin-screw extruder unit is designed to increase production and reduce maintenance costs.
It is commonly used to produce a variety of plastic products, including automotive parts, electronic components and household items.
