The VTA Evaporator Support Bar (VKL 75) is a stainless steel structural support bar that stabilizes the glass evaporator body on the VKL 75 wiped-film distillation system frame. It prevents lateral movement of the evaporator during operation and vibration from the wiper drive, protecting the glass assembly from stress fractures. An OEM VTA replacement structural component for VKL 75 series distillation systems; replace if bent, corroded, or damaged.
