Magonhi emafiriji ekuratidzira makabati anowanzo gadzirwa neaviri magirazi akaiswa pafuremu yemuviri wegonhi, uye desiccants inowedzerwa pakati pekaviri-layer girazi kuita chisimbiso chakapetwa kuita girazi rinodzivirira, uye rinogona zvakare kuzadzwa nenitrogen. ine zvishoma zvishoma kupisa conductivity.kana helium.Gonhi nekabati zvakabatanidzwa nemahinji.

Zvishandiso zvinodiwa kugadzirisa firiji-magirazi maviri magonhi:

Otomatiki gasi pamhepo yekuzadza Insulating girazi yekugadzira mutsara, butyl yekuisa muchina, sealant yekuisa muchina, aluminium bending muchina, desiccant kuzadza muchina, aluminium spacer framer kutamisa muchina.
