KoldLok® is the industry leader in advanced sealing technology and these energy-efficient grommets are proven to increase the volume of conditioned air delivery through perforated tiles and floor grates. Increasing the existing cooling unit capacity in a facility reduces the need to purchase additional cooling units, which is both economical and smart.
