Deutsche Hydrapro in New Zealand

Electric over hydraulic brake actuators for trailers

Fast, strong and consistent disc braking for boat trailers, car carriers, plant trailers and caravans. Your electric brake controller signals the actuator, and it delivers hydraulic pressure to the disc brakes in a fraction of a second.

How it works

Electric control, hydraulic stopping power

Electric drum brakes are fine on lighter trailers. Heavier loads, and trailers that get dunked in salt water, are better off with hydraulic disc brakes. An EOH actuator lets you run disc brakes off the electric brake controller you already have.

You brake

Your in-cab electric brake controller sends its normal signal down the trailer plug.

The actuator responds

A DC motor and pump in the actuator build hydraulic pressure in proportion to that signal.

The discs clamp

Brake fluid pressure applies the trailer's disc brakes, smoothly and consistently.

Why Deutsche Hydrapro

Built for harsh conditions

Built-in compatibility adapter

Works with standard electric brake controllers without an external adapter, for plug-and-play simplicity.

Consistent, proportional braking

A wide proportional braking range and consistent force at maximum pressure, with high braking force for the power drawn.

Sealed against salt and grime

Anodised T6 extruded alloy housing, an independently sealed fluid tank and a conformal-coated circuit board. IP67 rated.

The Deutsche Hydrapro story

Why an Australian company has a German name

Founder Dr Dale Hynd grew up around the Australian trailer industry. While studying in the UK he found the brake actuators on offer unreliable, so he started designing his own pump. When a respected European hydraulics manufacturer wouldn't take his calls, he and a group of fellow engineers flew to its headquarters and waited in the lobby until they got a meeting.

The manufacturer agreed to build the pump, and Deutsche Hydrapro was born, named as a nod to that partnership and its 90-plus years of hydraulic engineering. The company is based in Victoria, and its actuators are sold across Australia, New Zealand and North America. In New Zealand, Deutsche Hydrapro is distributed and supported by TowPro Group.

Common questions

Good to know

Does it work with my brake controller?

The actuator has a built-in compatibility adapter and works with standard electric brake controllers. Some factory-fitted in-cab controllers, mainly on certain Ford, RAM and GM models, need an extra adapter to detect an EOH system. Check the compatibility list above, or ask us before you buy.

Can I use it with drum brakes?

The Alpha G1600 is optimised for hydraulic disc brakes. If your trailer has electric drum brakes now, talk to us about converting to discs.

What brake fluid does it use?

DOT 3 or DOT 4 only. Don't use Super DOT 4 or DOT 4+.

What power supply does it need?

12V DC on a circuit of at least 30 amps. It draws 18 to 24 amps at full pressure, so heavy-gauge wiring is needed for the power and ground. See the wiring diagram and the voltage drop calculator above.

What warranty does it have?

A 2-year warranty from Deutsche Hydrapro. Claims in New Zealand are handled through TowPro.
