Overview

EN 45510-6-5:1999 (CLC) is a procurement guide for dry cooling systems used in electricity generating stations. It provides guidance for preparing technical specifications for natural-draught and mechanical-draught dry cooling towers, air-cooled condensers and associated internals. The Guide is intended for conventional power stations and explicitly excludes equipment used within the nuclear reactor plant area. Other non-power-station applications are not covered.

Key topics and requirements

This standard focuses on structuring technical procurement documents and addresses key technical topics that specifiers should include:

  • Scope and applicability - types of dry cooling equipment covered (natural and mechanical draught towers, air‑cooled condensers) and limitations (not for nuclear reactor plant areas).
  • System components - required content for describing water distribution systems, heat exchangers, and internal components.
  • Mechanical structures - guidance on specifying supporting frames, footbridges and structural interfaces with the power station.
  • Performance and interfaces - expectations for operational and installation interfaces with turbine auxiliaries (without prescribing numerical performance values).
  • Documentation and deliverables - recommended specification of drawings, testing, inspection and handover documentation.
  • Quality and safety considerations - inclusion of material, fabrication and inspection clauses to ensure reliable, maintainable installations.

(Items above reflect the Guide’s remit to help prepare complete technical specifications rather than detailed design prescriptions.)

Applications and users

EN 45510-6-5 is practical for organizations involved in the procurement, design and installation of dry cooling equipment for thermal power plants:

  • Procurement specialists and contract writers preparing tender specifications.
  • Plant engineers and designers defining system interfaces with turbine auxiliaries.
  • EPC contractors and project managers overseeing equipment supply and installation.
  • Manufacturers and suppliers responding to tenders who need to understand buyers’ expected specification content.
  • Operations and maintenance teams who benefit from clearer specification of internals and access provisions (e.g., footbridges).

Using this Guide helps ensure consistent, clear procurement documents, reduces ambiguity in tenders, and improves vendor comparability for dry cooling systems and air-cooled condensers.

Related standards

  • Other parts of the EN 45510 series covering procurement of power station equipment and turbine auxiliaries.
  • National or industry standards addressing structural design, materials, and site installation where detailed technical rules are required.
