HMC (Hybrid Modular Cooler) is a modular cooler, developed from the legacy Hybrid Coolers based on 30+ years of operational experience. Each HMC module is of deluged type with 1 pc horizontal cooling delta. The airflow through the module is induced by fans located on top of the delta. The deluge system provides additional cooling capacity. Each HMC module is a fully independent unit, including steel structure, two pieces heat exchangers arranged horizontally into a cooling delta, fan units, deluge water system, and control cabinet.
