ENERGY GUARD Dock Sealing System Ask An Expert Request a Quote Request Service Or give us a call: 1-888-606-9415 The ENERGY GUARD dock sealing system is designed to provide the ultimate degree of perimeter sealing for your dock leveler. It is the best solution to seal your internal environment from outside air. Air-conditioned or freezer facilities find that this product will often pay for itself in less than a year due to the resulting energy savings. Gaps between the dock leveler and the building envelope create opportunity for air, dirt, debris and pest infiltration. Most dock levelers on the market today are not able to achieve effective perimeter sealing. In response to this problem, the ENERGY GUARD dock sealing system was developed. The ENERGY GUARD system consists of a series of perimeter seals that create an effective barrier between the leveler and pit, preventing energy losses and physically isolating the interior and exterior environments. The ENERGY GUARD system is available as a factory installed option on most Kelley dock levelers or can be easily retrofitted on existing dock levelers. The seals are compatible with pit dock leveler systems from most major manufacturers.
