Abstract: An air cooled condenser fan deck subassembly system and method including eight subassembly parts which are pre-assembled prior to arrival at the final assembly location. The eight subassembly parts include four inner subassembly parts and four outer subassembly parts, each of which are sized to fit in a standard sea container. Once the eight fan deck subassembly parts are delivered to the site, they are unloaded and bolded together, resulting in significant time and cost savings to the purchaser and erector.

Abstract: A dry heat exchanger coil having a plurality of straight inner tubes connected by a plurality of return bends. The return bends are located outside of the air flow passing over the coil. The inner tubes are situated within a corresponding outer or “safety” tube. The outer tubes do not contain and are not connected to return bends, but the ends of the outer tubes are located outside of the air flow path. Leaks in the inner tubes are captured by the outer tubes and the leaking fluid will flow in the space between the inner and outer tubes, flow out the end of the outer tube, to be captured in a drip pan at the bottom of the coil housing. Leaks occurring in the return bends will also be captured in drip pan.
