Motor operated louvers mounted before the deltas protect the finned surfaces and allow the airflow to be controlled. Fig. 16 Dry-Cooling Towers at the Razdan Power Plant, Armenia. Other more recent Heller systems include the 8 x 250 MWe Shahid Rajai power plant in Iran described by Ludvig, the 2 x 200 MWe Datong power plant in China, and the 2 x 200 MWe Teshrin plant that commenced operation in 1993 according to Spilko. In some indirect cooling systems, a conventional surface condenser is employed instead of the spray condenser.

The plant is located in an arid, coal-rich area 1240 m above sea level where extreme climactic conditions are experienced (-40 °C to 43 °C). 9 became operational in 1978. Details of its dimensions, operation, and performance are reported by Schulenberg and Kosten et al.
