    DYNACO Freezer High Speed Door (Interior)

    Engineered specifically for freezer applications, the DYNACO M2 Freezer door provides the industry’s fastest return on investment and lowest life cycle cost.

    This energy saving door system minimizes convection, conduction and infiltration energy loss. Faster cycle speeds (up and down), an insulated curtain (optional) and tighter seals around the perimeter reduce loss of cold air. All of this is accomplished without compromising speed or safety.

    Fast Speed

    Significantly reduces energy costs due to lost temperature control; dramatically improves productivity and safety.

    Insulation

    An insulated door curtain consisting of two layers of PVC filled with insulating material can be specified to reduce convection.

    Tight Seal

    On all four sides of the opening minimizes infiltration, inhibits water, dust, pests and other contaminants.
