Engineered for Industrial Strength

FeatureDescription
Sealed Gearmotor BodyDesigned for wet, abrasive, and corrosive environments
Washdown-ReadySupports frequent cleaning cycles common in car washes and food facilities
Control PanelNEMA 4 standard, NEMA 1/12 optional

Sealed Control Module

GDI sealed control module with integrated display and sealed connectors
Sealed controller with integrated interface and sealed connector architecture.

Engineered for harsh, wet, and high-duty environments, the sealed control module protects critical electronics from moisture, dust, and spray while maintaining stable performance and fast diagnostics. A gasketed housing and sealed cable interface help keep water out during washdowns and weather events, while the integrated LCD streamlines setup, status checks, and fault review at the door. Service-friendly connectors support quick swap-outs and upgrades without disturbing the enclosure seal, helping minimize downtime and keep cycles moving.
