Restaurants, food service industries and other businesses with cold storage feel a chill when energy bills arrive each month; the necessity of constant movement between refrigerated areas and work locations leads to a constant drain on power. Curtron Products, Pittsburgh, Pa., developed a swinging solution to the problem—the new Polar-Pro™ Gravity Hinge flexible swinging door, with PVC panels that allow visibility while keeping the cold in cold storage and icy drafts from work spaces.

Personnel and light mechanical traffic move easily through the doors, which then automatically close to separate temperature zones. The Polar-Pro GH fits door openings up to 60 inches wide and comes in both standard and low-temperature PVC capable of withstanding 0 to –20 degrees F. Hardware of high-performance stainless steel features a lifetime guarantee against rust and corrosion.
