Multilec Engineering has designed and developed custom solutions for testing, diagnostics and analysis of hydraulic controls.

Portable equipment is used to test control valves with the following operational parameters:

  • Pelican case for storage and transports
  • 240vac input or multil voltage dc inputs (drill battery, car battery, power supply)
  • Voltmeter to read voltage to the coil
  • Amp meter to read the current draw of the coil
  • Range of leads can be manufactured as per the clients requirements
  • Data logging to record all values of the test
  • Internal Amplifier card to drive all makes and types of proportional coils
  • Millivolt, volt, amps and milliamps input and output control
Electro Hydraulic Test Equipment

The design and development of the test equipment is an ongoing project with feedback from technicians and end users to effectively diagnose faults onsite.

Onsite systems have become more heavily electrical interlocked and the setup of electro hydraulic controls can be more problematic. Being able to load parameters into controllers and simulate the operation without the interlocks impediment is crucial for testing and setup for the onsite technicians.


Multilec Engineering has been involved in the line boring Industry and have manufactured HPU control panels for a number of hydraulic companies. From this experience we have developed in conjunction with Danfoss an offering to the market that is fit for purpose.
