New apparatus at O’Hare

Gordon J. Nord, Jr. captured a series of striking images at O’Hare International Airport, showcasing four new ARFF (Aircraft Rescue and Firefighting) units from Oshkosh. In addition to the vehicles, he was given an exclusive look at 9-2-4, the newly introduced mobile ventilation unit, which is set to enhance emergency response capabilities at the airport. The first photo features Engine 6-5-3 in action, with its bumper turret flowing water. This image highlights the power and precision of the new ARFF units as they prepare for potential emergencies. Another shot shows 6-5-3 rolling out of Rescue 1, demonstrating how these units are strategically positioned across the airport to ensure rapid response times. Engine 6-5-7 is also stationed at Rescue 1, reinforcing the strong presence of the Chicago Fire Department at key locations. Meanwhile, 6-5-4 can be seen at Rescue 3, while 6-5-5 is located mid-field, both part of the ongoing effort to maintain comprehensive coverage throughout the airfield. Another unit, 6-5-9, is based at Rescue 4, which is situated in the old north fire station near Touhy Avenue. These placements reflect the department’s commitment to ensuring that every area of the airport is well protected. In addition to the ARFF units, the mobile ventilation unit 9-2-4 stands out as a modern addition to the fire department’s fleet. Designed to assist in smoke removal and improve visibility during aircraft incidents, this unit represents a significant advancement in firefighting technology. These photos not only provide a visual tour of the latest equipment but also offer a glimpse into the daily operations of one of the busiest airports in the country. Gordon J. Nord, Jr.’s work captures the dedication and professionalism of the Chicago Fire Department as they continue to protect travelers and staff alike.

Box Heat Exchange Station

A Box Heat Exchange Station, also known as a Prefabricated Heat Exchange Station or Modular Heat Exchange Station, is a compact, pre-assembled unit used for heating, cooling, or heat recovery in district energy systems, HVAC systems, or industrial processes. These stations are designed for easy installation, energy efficiency, and space-saving. Below is a classification of Box Heat Exchange Stations based on their design, function, and application:

1. Based on Function

  • Heating Station:

    • Designed to supply heat to a building or district heating network.

    • Typically includes a heat exchanger, pumps, and control systems.

  • Cooling Station:

    • Used for cooling applications, such as district cooling or industrial processes.

    • Includes chillers, cooling towers, or heat exchangers.

  • Combined Heating and Cooling Station:

    • Provides both heating and cooling capabilities.

    • Often used in systems with seasonal demand changes.

  • Heat Recovery Station:

    • Recovers waste heat from industrial processes or exhaust air.

    • Reuses the recovered heat for other purposes, improving energy efficiency.

      2. Based on Design

      • Compact Modular Station:

        • Prefabricated and pre-assembled in a factory.

        • Easy to transport and install on-site.

        • Ideal for small to medium-sized applications.

      • Skid-Mounted Station:

        • Mounted on a skid or frame for easy mobility.

        • Commonly used in temporary or portable applications.

      • Containerized Station:

        • Housed in a shipping container for protection and portability.

        • Suitable for harsh environments or remote locations.

          3. Based on Heat Source

          • District Heating Station:

            • Connects to a district heating network to supply heat to buildings.

            • Includes heat exchangers, pumps, and control valves.

          • Geothermal Heat Exchange Station:

            • Utilizes geothermal energy as the heat source.

            • Includes ground-source heat pumps and heat exchangers.

          • Solar Thermal Station:

            • Uses solar collectors to capture and transfer heat.

            • Often includes thermal storage systems.

          • Waste Heat Recovery Station:

            • Captures and reuses waste heat from industrial processes or power plants.

              4. Based on Application

              • Residential Heat Exchange Station:

                • Designed for small-scale residential heating or cooling.

                • Compact and energy-efficient.

              • Commercial Heat Exchange Station:

                • Used in office buildings, shopping malls, or hotels.

                • Handles larger heating or cooling loads.

              • Industrial Heat Exchange Station:

                • Designed for industrial processes, such as chemical plants or manufacturing facilities.

                • Often includes robust components for high-temperature or high-pressure applications.

              • District Energy Station:

                • Supplies heating or cooling to an entire district or community.

                  • Water-to-Water Heat Exchange Station:

                    • Transfers heat between two water circuits.

                    • Common in district heating and cooling systems.

                      Includes large-capacity heat exchangers and pumps.
