Most equipment is designed for an average day. In Northern Ontario, the average day isn’t the one that breaks things. It’s the January morning when a machine has sat outside overnight and the thermometer reads -40.
What extreme cold does to fluid systems
Anyone who runs equipment up here already knows the symptoms. Hydraulic fluid thickens and flows poorly, so pumps work harder just to move it. Standard rubber seals and hoses become brittle and more likely to leak or crack. And the first few minutes after a cold start are when a lot of the damage happens.
Every one of those problems is also a monitoring problem. Thick fluid behaves differently, materials shrink and stiffen, and a reading that is accurate in a warm shop may not hold up outside.
Designing for the worst day
That shapes how we approach every design decision at Hodgins Holdings:
- Fewer moving parts. Anything that has to move in the cold is something that can stick.
- Nothing in the fluid. Measuring from above means no seals or probes sitting in thickened oil.
- Temperature is part of the measurement. Readings have to stay consistent from a warm cellar to a frozen job site, not just at room temperature.

Why build it here
There's an advantage to developing hardware where the conditions are hardest. We haven't put our system through a -40 winter yet. Cold-weather testing is a core part of our validation plan, and we'd rather find the weak points here than in a customer's yard.
