Xchanger, Inc. products

The AA Series heat exchangers are designed to efficiently cool low pressure gas streams using ambient air, offering an ideal solution for environments with restricted cooling water access. These air-cooled units are equipped with a TEFC 230/460 VAC, 3-phase motor, a robust cooling fan, and an OSHA-compliant fan guard, with options for alternate motors when necessary. Constructed with a galvanized steel exhaust hood and venturi frame, the heat exchangers utilize an aluminum plate-fin core, which is furnace brazed for enhanced durability. The process gas moves horizontally while ambient air flows vertically, ensuring efficient heat dissipation. Applications include aftercooling for Roots type and multistage centrifugal blowers in various systems, such as pneumatic conveying and wastewater aeration. Installation is recommended outdoors or in well-ventilated indoor spaces. Xchanger provides multiple models and uses computer modeling and fan performance databases to optimize heat exchanger performance.

The BG Series Heat Exchangers are designed for the cooling and dehumidification of biogas streams, particularly those originating from landfills and digesters. This series features a modular design that allows easy modification to fit custom specifications, making it versatile for various applications. Typical uses include aftercooling and heating gas delivered by rotary-lobe and multistage centrifugal blowers in biogas and landfill gas systems for power generation and cogeneration. It has a robust pressure housing design that allows for removable cores from the rear without disassembling the gas line. The heat exchanger housings can accommodate multiple cores and mist eliminators, reducing downstream moisture carryover. With easily adjustable gas connection sizes, the device adapts to different system needs. Featuring a fin-tube core with expanded tubes, the design ensures optimal performance and structural integrity through gap-free connections. Installation considerations address fluid circuit drainage and vibration isolation to prevent work-hardening and failures.

The C Series Heat Exchangers by Performance Xchanger are designed to efficiently heat and cool low pressure gas streams, featuring a modular design that allows for customization to suit specific requirements. These exchangers are particularly applicable in systems involving aftercooling, dehumidifying, and heating air delivered from rotary-lobe and multistage centrifugal blowers, commonly used in pneumatic conveying and air separation. The modularity extends to housing that permits easy removal of heat exchanger cores from both sides without disassembly of the gas line. Key design elements include the fin-tube core, where metal fins are attached to tubes through a die-extrusion process, ensuring maximum structural integrity and heat transfer efficiency. To maintain fluid dynamics, the circuits are oriented for effective drainage, preventing trapping, and optional intermediate headers are available to enhance drainage and frost protection. Additional features include adapting gas connection size and incorporating mist eliminators. A variety of models are available, designed to meet various operational needs.

The D Series Heat Exchangers are engineered for specific applications in dairy processes, including heating, cooling, dehumidifying, and filtering low-pressure air streams. Designed with optional HEPA filters and fully clad insulation, these modular systems provide flexibility for customization. Notable for their suitability in blower precooling, dehumidifying, and aftercooling, they offer efficient handling of pneumatic conveying processes within dairy operations. The heat exchanger cores are easily accessible, enabling removal through the housing cover without needing gas line disassembly. They accommodate design pressures from a full vacuum to 15 PSIG and can integrate mist eliminators to reduce moisture. The fin-tube core structure features die-extruded tube collars, enhancing heat performance and structural robustness. Installation is crucial for optimum efficiency, with considerations for fluid circuit configurations and vibration isolation mechanisms. The product is analyzed using advanced engineering practices to ensure performance reliability, with models available in D-500, D-1000, and D-2000.

The HP Series Heat Exchangers are designed to efficiently heat and cool pressurized gas streams at pressures up to 100 PSIG. These heat exchangers are commonly used in applications such as aftercooling, dehumidifying, and heating air delivered from compressors in pneumatic conveying, air separation, and charge-air systems. The design features a removable heat exchanger core, enabling easy maintenance without disassembly of the gas line. Built according to ASME Section VIII, Div. 1 pressure vessel codes, the housing ensures reliability and compliance, with a code stamp available optionally. The fin-tube core design incorporates rectangular plate fins with die-extruded tube collars, maximizing heat exchange performance through a gap-free tube expansion into the collars. The fluid circuit comprises parallel tube systems joined at inlet and outlet headers, designed to prevent fluid trapping. Performance engineers utilize sophisticated computer modeling for optimal design, ensuring robust analysis and adherence to standards.
