Control, Monitor and Protect Your Irrigation System Like the Good Old Days - But Better!
Remember when engine panels had gauges with needles, and wiring you could trace?
When a sensor failing didn't mean calling tech support or updating software?
Bolec Electronics brings that reliability back — designed for irrigation suppliers who install systems in real, muddy, Australian conditions.
About us
Bolec Electronics is an Australian, family-owned designer and manufacturer of rugged 12V/24V control systems, with over 40 years’ experience supplying OEMs and Tier 1 manufacturers. In recent years, we’ve worked closely with irrigation and pump operators across Australia, applying that same engineering approach to real-world farming conditions. Bolec remembers when equipment had to work every day without fuss—no menus, no complexity, just simple, dependable systems that keep water moving when it matters most.
The mechanical timer is an industry favourite - rugged and simple to use. The digital one follows the same design philosophy
TIMERS THAT JUST WORK
Old School Reliability.
New School Precision.
Our BMT-55 and Bolec digital timers are easy to install, intuitive, and engineered for harsh environments where reliability matters more than fancy features.
They replace discontinued timers and work straight out of the box.
ENGINE PROTECTION PANELS
Protect Your Pumps Further…
With DEM302 and DEM502 engine panels, fully customisable with Murphy-style gauges for oil, water, or coolant. Our engine watchdog panels provide robust protection for pumps and engines in remote or unattended environments. Designed in the style of classic Murphy panels, they feature large, easy-to-read gauges, simple wiring, and no reliance on complex digital interfaces. They monitor critical parameters such as temperature, oil pressure, and coolant level, and can shut down equipment before damage occurs. Importantly, they are fully serviceable and repairable, with direct access to the engineer who designed them here in Australia.
WHY??
Because these panels remember faults, are repairable in the field, and give you the confidence to troubleshoot without laptops or menus.
To complement these systems, Bolec offers muddy water sensors and a range of practical accessories designed for harsh irrigation environments. Our sensors are engineered to perform reliably in dirty, sediment-heavy water where standard probes often fail. Combined with float switches, relays, and other control components, they provide a complete, field-ready solution that integrates seamlessly with pumps, engines, and control panels.
Add WL701 water sensors to stop pumps running dry in muddy or mineral-heavy water — a reliable alternative to failing optical sensors.
Gauges with Needles.
Clearly Labelled Terminals.
Visible Wiring.
This is the detail that an experienced installer will notice and trust immediately. No hidden logic boards. No firmware updates in the field.
DESIGNED FOR THE FIELD
Designed to Save Time
and Prevent Downtime.
Bolec products are designed to save time, prevent downtime, and make field troubleshooting easy. You can call Melbourne engineers directly, trace wiring, bypass faults if necessary, and know that your system is rugged enough to last for years.
Australian Made Since 1978
Start with a Timer.
Build a System Your
Customers Will Rely On.
Start with a timer, expand to panels and sensors, and finally install a system your customers will rely on — saving time, money, and frustration with every install. Our timers are built with that philosophy in mind. From fully mechanical models that require no external power, to straightforward electronic timers, they are designed to be reliable, easy to set, and easy to replace. Many customers use them as direct replacements for discontinued units such as the ISGUS KS55, avoiding costly redesigns while restoring dependable operation. They are a proven favourite for farmers who want something that just works, season after season.
