Six Solutions for Industrial Heat Tracing & Process Heating
Industrial plants don’t buy products. They buy outcomes — pipes that don’t freeze, processes that hold temperature, systems that pass an audit, projects that finish on time. Our six Solutions package design, supply, installation, commissioning, and ongoing service into named programs. Pick the Solution that matches what you’re trying to solve.
Smart Heat Trace Monitoring
IoT-enabled monitoring. Remote dashboards, alarm notifications, predictive analytics, and periodic health reports on existing or new heat trace systems.
Heat Trace System Audits & Lifecycle
Formal heat trace audits including visual inspection, circuit and ground fault testing, controls review, minor troubleshooting, and a written report for compliance, corrective action, and budgeting.
Freeze Protection & Winterization
Annual freeze protection programs for Gulf Coast plants. Pre-season audits in August through October, certified install, priority response when a hard freeze hits.
Industrial Heater Repair & Replacement
Inspection, testing, troubleshooting, repair, design, specification, and replacement of process heaters—including circulation, immersion, in-line, and packaged skid heaters—for all major brands.
Process Heating & Temperature Maintenance
Electric heat tracing for viscosity control of chemicals, polymers, and waxes, including sulfur, heavy crude, and caustic lines. Tank heating and steam-to-electric conversion for improved energy efficiency.
Turnkey Heat Tracing Design-Build
Single-source design-build. Site survey, heat loss calculations, “As Built” isometric drawings, material supply, custom control panels, installation, commissioning.

Behind Every Solution: The Inventory That Keeps Gulf Coast Plants Running
Most heat tracing companies sell what they manufacture. We carry what plants actually need — across 20+ brands, in stock, on our shelves in Houston. That matters for two reasons. First, when a controller fails or a pressure switch needs replacing, parts ship same-day from Antoine Drive instead of three weeks from a factory back order. Second, we can specify the right product for your application instead of the only product we sell.

Why Plants and EPC Firms Choose WilsherCo
Industrial plants don’t buy products. They buy outcomes — pipes that don’t freeze, processes that hold temperature, systems that pass an audit, projects that finish on time. Our six Solutions package design, supply, installation, commissioning, and ongoing service into named programs. Pick the Solution that matches what you’re trying to solve.
Single-Source Responsibility
Most heat tracing work is split between a product vendor and an installation contractor. When something goes wrong, each side points to the other. We design it, supply it, install it, commission it, and service it. One contract. One accountable partner.
47+ Years on the Gulf Coast
We’ve been in Houston since 1978. We’ve seen every freeze event from the December 1989 cold snap through Winter Storm Uri. We know which plants need, where freeze protection fails, and we know how the petrochemical corridor actually operates.
Government Client Experience
Federal, state, and local government clients have trusted us with heat tracing on facilities where a freeze failure isn’t just expensive — it’s a safety incident. We know the procurement language, the documentation requirements, and the security expectations.

The Multi-Brand Advantage
Most competitors push their own product. We carry 20 brands and recommend the right one for your application, your system, your existing infrastructure. That’s not a slogan — it’s a structural difference in how we operate.
Industries We Serve
Heat tracing requirements vary by industry. Compliance, hazardous-area classifications, process temperatures, and audit cadence all shift depending on what you’re producing. We work across:
Chemical & Petrochemical
Oil & Gas
Power Generation
Government
Pharmaceutical
Data Centers
Food Processing
Commercial
Whether You’re Specifying, Procuring, Building, or Managing
Plant Engineers
We help you specify the right system, calculate heat loss, and get a design package you can submit for approval.
Procurement
One PO, 19 brands, stocked inventory. We make multi-brand sourcing simple.
EPC Firms
Turnkey design-build for new construction and major retrofits. As-builts, training, and commissioning included.
Government PMs
Track record with federal, state, and local agencies, plus the documentation discipline these projects require. Unique Entity ID (SAM) – L3LLKAM65W56; CAGE CODE – 8U416
Plant Managers
A well documented, operating system that can be monitored and is predictive.
Plant Maintenance
Regular maintenance prevents process fluid solidification and pipe freezing.
Operations Managers
One PO, 19 brands, stocked inventory. We make multi-brand sourcing simple.
Project Managers
A heat tracing system requires aligning technical parameters (freeze protection vs. process maintenance), procurement, and electrical infrastructure.
Real Projects, Real Results
We’ve documented two recent projects that show how the design-build process works in the field — including the constraints, the surprises, and the outcomes.
West Texas Compressor Station
Limited site power, sub-zero overnight temperatures, and a tight commissioning window. How we re-engineered the heat loss calc on-site to keep the project on schedule.
Ohio Compressor Station
Real-time pressure testing during a winter cold snap. How we kept the process lines warm while the customer ran final acceptance tests.
