Categories
Electric Start Assembly
Hilliard Electric Start Assemblies are designed for aero-derivative industrial turbine and reciprocating engine applications where reliable startup capability is required.
Extreme Duty Centrifugal Clutches
Hilliard Extreme Duty Centrifugal Clutches provide automatic engagement based on input shaft speed, allowing controlled torque transfer between engine and driven load without external actuation.
Friction Torque Limiter
Hilliard Friction Torque Limiters provide adjustable overload protection by transmitting torque under normal operating conditions while slipping at a predetermined torque setting when overload occurs.
Front Drive System (Differential)
Hilliard Front Drive Systems provide controlled torque distribution to the front axle while allowing independent wheel speed variation for steering and terrain adaptation.
Fuel Gas Filter/Coalescers
HILCO utilized computational fluid dynamics (CFD) software to optimize performance and provide customers with accurate predictions of equipment pressure loss before units are put into service.
Fuel Gas Strainers
HILCO’s duplex strainers incorporate a zero-leak transfer valve constructed from wrought materials rather than castings, allowing for superior integrity, as well as the flexibility to weld and modify
Gas Coalescer / Separator Cartridges
At the core of every HILCO Gas Coalescer / Separator Filter Cartridge is a precision-engineered gas coalescer cartridge designed to remove entrained liquids from gas and vapor streams.
