There are two main types of dry cooling systems: a direct air cooling system, typically known as an air-cooled condenser (ACC), and an indirect air cooling system, also called a Heller system. An ACC takes steam exhaust from the turbine and pumps it through the top of a long A-frame structure.
Mayroong dalawang pangunahing uri ng mga dry paglamig system: isang direktang hangin paglamig system, karaniwang kilala bilang isang pinalamig ng hangin pampalapot (ACC), at isang di-tuwiran hangin paglamig system, na tinatawag ding Heller system. Isang ACC tumatagal steam maubos mula sa turbina at sapatos na pangbabae na ito sa pamamagitan ng tuktok ng isang mahabang istraktura A-frame.
