The Simplex Trident 2500 Trailer load bank is ideal for field testing in the performance of start-up and commissioning activities, service contracts and engine generator maintenance. Rentals are available in 2500kw capacities. Operator interface is via touchscreen. Multiple Tridents may be networked together to yield total capacities of tens or hundreds of megawatts. Simplex trailers are built to DOT specification, NTM DOT certification label.
