HCT-12 or JEHA MK IV is an universal AIRCRAFT COMPONENTS TEST BENCHES which compromises of Main Hydraulic Console (MHC) and Pump and Motor Test Console (P&MTC). The MHC provides the Unit under Test (UUT) with the necessary input test parameters to perform functional and operational tests on hydraulic components/modules from new and old generation of both rotary and fixed wing aircraft through use of electrical, hydraulic and pneumatic circuits.

Since MHC is equipped with two independent high pressure dynamic circuits (each 20 GPM @ 6,000 PSI or 25 GPM @ 3,000 PSI), one independent low pressure dynamic circuit (max 10 GPM @ 250 PSI), one independent hydrostatic circuit (up to 10,000 psi) and two power supplies, one adjustable AC and one adjustable DC power supply, which they can be operated simultaneously, MHC can technically handle all required flow and pressure for testing various components as well servo controls and actuators.

P&MTC provides capabilities of testing hydraulic pump, motor and power transfer unit, and can be added to MHC at any time. MHC is the source of supplying hydraulic flow and pressure for testing of hydraulic rotating components, when connected to the Pump and Motor Test Console.

JEHA MKIV is the new generation, state-of-the-art Hydraulic Test Bench. Commercial (JEHA MKIV) and military versions HCT-12 (A/F27T-12) are available for selection. JEHA MKIV is built to meet fully with stringent environment testing like EMI, EMC, shock, vibration, noise etc. HII is building 80 sets and spares support will be guaranteed for the next 25 years.

Dual Independent Hydraulic System, each System is capable to deliver at least 25 GPM (or more if required) @ 3,000 PSI. Besides Hydraulic and provisions of AC & DC Power Sources, JEHA IV is equally capable to provide Hydrostatic, Pneumatic, Low Pressure Testing.

The Human Machine Interface (HMI) allows for human monitoring, input, and display of hydraulic fluid temperature and pressure, pneumatic pressures, fluid flow rates, and warning and status indicators. All input from temperature and pressure sensors and HMI inputs are processed by a Programmable Logic Controller (PLC). The PLC receives signal from flowmeters, temperature sensors, pressure transducers and also from HMI inputs and displays the measured valves on the HMI. JEHA MIV is designed with a combination of manual and automated controls. Critical Systems are still using mechanical controls.

No Gauges fitted on JEHA MKIV to be sent for calibration. Its Transducers or flowmeters also do not have to be removed for calibration. Instrument Verification Set (IVS) can be connected to JEHA MKIV to determine if Transducers or Flowmeters are within acceptable accuracy. JEHA MKIV is built with provision for ease of connecting to our Pump and Motor Test Console (P&MTC) if future expansion is required.
