(International Standards for Phytosanitary Measures) 1.2 SUMMARY Section includes plate heat transfer panels as detailed in drawings listed in Section 1.1 Related s. The panels are single embossed plate heat transfer panels manufactured with stainless steel plates 14ga/22ga [1.9mm/0.7mm]. The initial thickness of the plates will increase to an overall thickness of 3/8 [4.8mm] after the inflation process. The panels will be supported using a number of holes evenly distributed on its surface. The heat transfer fluid inlet and outlet shall be ¾ tube elbow to be socket welded to ¾ stool type fittings to minimize the pressure drop and provide a robust connection. Between inlet and outlet the fluid is guided by a system of baffles configured by the manufacturer to optimize the heat transfer, minimize the pressure drop and achieve as much as possible a uniform temperature distribution in the outer surface of the panel. Baffles are usually interrupted before the edge of the plate coil in order to allow part of the flow going through the gap and avoid causing a dead pocket and the corresponding hot spot. Finally, to simplify erection on site and maintenance operations the panels are provided with riveted nuts on the four corners ready to thread eyebolts for lifting. Detailed manufacturing drawings of each plate coil type shall be provided by the manufacturer. The heat transfer fluid will be based on Dynalene HC SUBMITTALS Type Of submitted with Bid Proposal 3.0 General. 3.1 List of references X 3.2 Proposal: scope of supply (including exceptions to X the specification) Submittal Schedule (week after PO) Upon Completion

3 2. PRODUCTS 2.1 PERFORMANCE REQUIREMENTS A. Basic thermal and hydronic quantities are scheduled for each panel in DKIST-RFQ-205- DSH Plate Heat Transfer Panels Datasheet. B. Seismic Performance: Heat exchangers shall withstand the effects of earthquake motions determined according to ASCE/SEI 7. C. The term "withstand" means "the unit will remain in place without separation of any parts when subjected to the seismic forces specified. D. Component Importance Factor is 1.5. E. Panels shall be able to withstand typical loads for a cladding system, such as high wind loads. F. Panels shall be provided with an external non-pressurized welded strip ½ width in general and 1-1/2 in the panels forming the interface between different Enclosure planes (according to project drawings). The manufacturer shall ensure that this strip can be cut on site for erection without compromising the structural/hydraulic performance of the panel. 2.2 PLATE HEAT TRANSFER PANELS A. Construction: Fabricate and label heat exchangers to comply with ASME Boiler and Pressure Vessel Code, Section VIII, "Pressure Vessels," Division 1. B. Painting and Finishing: The exterior (non-expanded) side of the panels shall be painted with Energy Seal Acu-Shield white acrylic elastomeric coating manufactured by Advanced Coating Systems (or AURA approved equivalent), with a certified reflectivity greater than 84% on the outer surface after 3 years and initial near-normal emittance of 94% or greater. The paint shall be Energy Star certified. a. Before any priming or painting, all surfaces shall be free from grease, oil, weld spatter, sand, rust scale, and other contaminants that might interfere with the application of the finishing material. b. Performance tests shall be conducted in prototype pieces in order to ensure the correct application of the painting (avoid lack of adhesion, marks, etc.). c. The first or priming coat of paint shall be applied as promptly as possible after the surface has been prepared for painting. Otherwise, precautions will be taken to protect the surfaces from dust and corrosion until they are finished. Previous coats of paint shall be completely dry before subsequent coats are applied. d. Surfaces that do not require paint, shall be identified on the engineering drawings and masked or otherwise protected during painting. Unless otherwise stated, all threaded holes will be protected and free of paint. e. Panel Manufacturer shall follow all directions and recommendations from the coating manufacturer. 2.3 PLATE HEAT TRANSFER PANEL HANDLING JIG A. Manufacturer shall provide two sets of any and all tools and jigs required to handle the plate heat transfer panels during installation in the field. 2.4 TESTING REQUIREMENTS A. The plate heat transfer panels, fittings, and accessories shall be subjected to testing that is compliance with ASME codes. DKIST-FTS-205 Plate Heat Transfer Panels Page 3 of 5

4 B. The Manufacturer shall prepare a test plan to be approved by AURA prior to completing the tests. C. Testing procedures shall be performed by qualified personnel. D. All the equipment used for the test shall be in proper conditions and calibrated. E. The reports, personnel qualification, calibration data sheets, etc. shall form part of the QA records. F. The final state of the panels after testing shall be clean and in compliance with Dynalene HC Engineering Guide requirements for new systems using Dynalene HC. 2.5 NAMEPLATES Each panel shall have a durable nameplate affixed to the inner side for identification (noting that the panels are being assembly leaving the flat plate as the exterior side). The nameplate shall include, as a minimum, the following information: A. Panel Mark according to DKIST-RFQ-205-DSH Plate Heat Transfer Panels Datasheet; B. Nominal flow; C. Operating and maximum pressure; D. Empty weight; E. Full weight; F. Pressure drop at nominal flow; G. Thermal capacity for t=4ºc. DKIST-FTS-205 Plate Heat Transfer Panels Page 4 of 5

5 3. PACKAGING AND TRANSPORT 3.1 MARKING AND PACKAGING A. The packaging shall be crates made of ISPM 15 compliant high quality virgin woods, free of alien species sufficient for maritime international transport, with adequate blocking and other bracing to securely hold and protect the panels and accessories against water, condensation, and the marine environment even in rough seas. B. All Plate Heat Transfer Panel inlets, outlets, and other pathways to the interior of the panels shall be well protected from mechanical damage and equipped with factory-applied caps. C. The panels shall be documented and organized to facilitate storage and subsequent identification and removal for installation. D. Packaging and Transportation Plan, including the identification of all the transportation packages (dimensions, weights and handling indications), as well as the transportation planning, identifying the delivery date of all the transportation packages. 3.2 TRANSPORT A.
