Page 4: General Information
- Spare parts are warranted only if the storage instructions have been followed (see the section on storage). - CIAT must be promptly notified of any defects, in writing. If CIAT’s liability for the defect is proven, CIAT pledges to react quickly and to remedy it within the terms of the warranty. -
Page 5: Receiving The Unit
If any damage is found or the delivery is incomplete, make a detailed note of the non-conformity on the delivery note and inform the carrier by registered letter within three days of delivery and forward a copy to CIAT. -
Page 6: Intended Use
1.7 - Intended use - CIAT gasketed plate heat exchangers are designed to heat or cool fluids by means of heat transfer through indirect contact with another fluid. - Your heat exchanger’s specific operating conditions are set out in the order documents. -
Page 7: Data Plate
1.9 - Data plate - Stuck to the rear and front plates - MANUFACTURING YEAR:Y ear of manufacture. - MODEL: for example, PWB 4 11 027H00. 4 = Model. 1 = Number of passes for the hot fluid. 1 = Number of passes for the cold fluid. 027 = Number of plates, H = Type of plates (H high efficiency, L low efficiency, M mixed). -
Page 8: Installation
3.2 - Installation recommendations - CIAT plate heat exchangers have a limited operating pressure and temperature range. Install all the necessary safety devices to prevent overrunning the limits specified on the order documents. Approval to use the plate heat exchangers in different conditions from those detailed must be obtained from CIAT. -
Page 9: Insulation And Protection Accessories
- All maintenance operations must be carried out by qualified, trained personnel. - The heat exchanger may not be altered in any way without CIAT’s consent. - As the maintenance intervals depend on several parameters (fluids, temperature, etc.), the frequency of preventive maintenance is left to the operator’s judgment. -
Page 10: Disassembly
5) Retighten the plates to the dimension shown on the data plate. 5.2 - Disassembly - Breaking the special quality strap around the heat exchanger will void the warranty. You must obtain CIAT’s written permission in order to remove the strap. -
Page 11: Detergents
- Corrosion, galvanic coupling and erosion can create holes in the plates. As such damage is not always visible to the naked eye, we recommend performing liquid penetrant tests to check for holes or microcracks. CIAT’s technical support team can advise you on the appropriate products. -
Page 12: Gasket Replacement
5.7 - Gasket replacement - Before starting, check the manufacturing date of the gaskets, printed on the relevant date stamp (Fig.5). Please note that the gaskets must not be stored for more than 6-12 months (see chapter 2 - STORAGE). - Remove the old gasket without using cutting tools, which could irreparably damage the plate. -
Page 13: Reassembly
- Overtightening may irreversibly distort the plates. If you feel it is necessary to tighten beyond the recommended dimension, contact CIAT’s After-Sales Department to obtain advice. 3)It is recommended to perform a pressure test after all maintenance on the plates and gaskets in order to check the heat exchanger’s internal and external tightness. -
Page 14: Arrangement Examples
- If the length is insufficient, provide new carrying bars and threaded rods. - Replace the data plate and the plate arrangement drawing with the new ones provided by CIAT. - Leaks often occur when plates with new gaskets and plates with old gaskets are used together (due to difference in toughness). -
Page 15: Troubleshooting
POSSIBLE SOLUTIONS o If welded union couplings are used, check the condition of the welding. o If cracks are found, contact your CIAT consultant before attempting any repairs. o If other union couplings are used, contact your CIAT consultant.
