The Ventless process eliminates the installation cost of a hood, annual operational cost of the hood/fan, and hood ventilation system cost. Water entering the booster heater has been pre-heated, reducing the energy cost to bring booster temperature to required 120f degrees, potentially saving THOUSANDS of $ in operation costs. The EST-Ventless is provided with “Door Safety Interlock”, to prevent operator from interrupting the ventless process that removes vapor from the machine. The EST-VL features a 20-1/2” dish clearance.
