Motor Operators For Service Doors And Grilles
Operators are compact integral units designed for durability and reliability. Electrical enclosures are NEMA rated. Motor horsepower and components are conservatively rated for each door size and type according to best engineering practice.
Motor operators pay for themselves in convenience and conditioned air conservation. Control stations can be located to save time and allow uninterrupted traffic flow, and energy svings provided by motor operation soon returns the original investment.
Operator mountings are available to suit all clearance conditions. Design permits mounting to the side, above or in front of the hood.
Electric or Pneumatic Doors Edges (optional with motor operated doors only) when hitting an obstruction will (stop) (stop and reverse to the open position). Also serves as bottom weatherstripping.
