Zomangira zomangira zitsulo ndi mtundu wa chomangira chomwe chimagwiritsidwa ntchito kulumikiza zitsulo ndi zinthu zina. Amapangidwa ndi nsonga yakuthwa yomwe imawalola kuti azitha kubowola zitsulo pamene akuphwanyidwa, kuthetsa kufunika koboola kale.

Zomangira izi zimagwiritsidwa ntchito nthawi zambiri pantchito yomanga, makamaka pakupangira denga ndi mphepete. Amagwiritsidwanso ntchito m'makampani amagalimoto komanso pakuyika kwa HVAC.

Zomangira zachitsulo zodzibowolera zokha nthawi zambiri zimapangidwa ndi chitsulo cholimba kapena chitsulo chosapanga dzimbiri, chomwe chimapereka mphamvu komanso kukana dzimbiri. Zimabwera m'miyeso yosiyanasiyana komanso zomaliza kuti zigwirizane ndi ntchito zosiyanasiyana.

Chimodzi mwazabwino kwambiri zomangira zomangira zitsulo ndikuthamanga kwawo komanso kumasuka kwa unsembe, chifukwa zimachotsa kufunikira kobowola ndi kumangirira. Kuonjezera apo, amapereka mgwirizano wamphamvu, wotetezeka pakati pa pepala lachitsulo ndi zipangizo zina.
