The Midwest doesn’t ease into winter — it arrives. One week of mild temperatures can turn into a hard freeze overnight, and by the time ice forms in a process line or water sits frozen in a pipe, the damage is already done. For facilities that rely on heat trace to protect critical infrastructure, the real question isn’t whether winter is coming. It’s whether your system is actually ready for it.
At RELCON, we’ve spent four generations helping commercial, industrial, and utility facilities across the Midwest answer that question before the temperature drops — not after. Here’s how to know whether your heat trace system will hold up, and what to do if you’re not sure.
Why Heat Trace Readiness Matters
Heat trace cable is easy to forget about — it’s tucked under insulation, running along pipe racks, or buried inside equipment enclosures most of the year. But when a burst pipe, a frozen instrument line, or a failed fire sprinkler system shuts down operations, the cost is rarely just repairs. It’s downtime, safety exposure, and in some cases regulatory consequences. A system that worked fine last winter isn’t guaranteed to work this winter — cable degrades, connections loosen, and controllers drift out of calibration. Readiness has to be checked, not assumed.
Warning Signs Your System Isn't Ready
Before the first freeze, walk your facility — or have a professional walk it with you — and watch for these red flags:
- Cable age or visible damage: cracked, brittle, or discolored heat trace cable, especially anything installed more than 10–15 years ago.
- Nuisance breaker trips or GFEPD faults: a sign of insulation breakdown or moisture intrusion in the cable or connection kits.
- Controllers that won’t hold a setpoint: electronic controllers or thermostats that cycle erratically, or that no one on site has verified in over a year.
- Missing or damaged insulation: exposed, wet, or crushed insulation around traced piping and equipment lets heat escape faster than the cable can replace it.
- No documentation or recent audit: if you can’t point to a report on your system’s condition, energy performance, and compliance status, you don’t actually know where you stand.
- Unaddressed findings from last year: any issue flagged in a prior inspection that was never resolved will still be there when the cold hits.
The RELCON Readiness Checklist
A quick self-check before you call in a professional:
- Has the heat trace cable been visually inspected for damage this year?
- Do all circuits show proper continuity and current draw at the panel?
- Are controllers and sensors calibrated and cycling as expected?
- Is insulation intact, dry, and properly sealed along all traced lines?
- Do you have an up-to-date audit report covering energy efficiency, equipment performance, and safety compliance?
If you answered “no” or “not sure” to any of these, it’s time for a professional assessment — not a guess.
What a Professional Heat Trace Audit Covers
A RELCON Complete System Audit goes beyond a visual check. Our team evaluates your system across four areas and delivers a detailed report with findings, observations, and recommendations:
| Audit Area | What We Check |
| Energy Efficiency | Identifying excess energy use and opportunities to reduce operating cost. |
| Equipment Performance | Verifying cable, controllers, and components are functioning as designed. |
| Compliance & Safety | Confirming your system meets applicable codes and safety standards. |
| Maintenance Practices | Reviewing current upkeep against best practices to extend system life. |
Why Facilities Trust RELCON
RELCON specializes in engineered winterization for commercial, industrial, and utility facilities — not residential plumbing. That focus matters when the stakes are process integrity, fire sprinkler safety, and regulatory compliance rather than a single frozen faucet.
- Manufacturer-backed expertise: as a primary partner for Chemelex (Raychem) self-regulating heat trace cable, connection kits, and electronic controls, we design and troubleshoot systems built on proven, industry-standard components.
- Full-system perspective: from process winterization and floor warming to equipment enclosures and instrument tubing bundles, we look at how every piece of your thermal management system works together.
- Hands-on support: on-site training, start-up and commissioning assistance, and troubleshooting for panel and intelligent controller programming — so your team isn’t left guessing after we leave.
- Four generations of experience: engineered around real Midwest weather data, not generic assumptions.
Take Action Today
Our calendar is filling quickly as facilities across the Midwest prepare for the season ahead. Don’t wait for the first hard freeze to find out your system wasn’t ready. Contact RELCON today and let four generations of thermal expertise protect your facility this winter.
