Heat Exchanger & Pressure Vessel Cleaning
Engineered Chemical Cleaning for Critical Industrial Systems
Industrial chemical cleaning should not feel like a maintenance task.
It is a performance intervention.
At Valkyrie Industrial Cleaning, we design and execute engineered chemical cleaning programs that restore thermal efficiency, stabilize process systems, and protect asset integrity across oil & gas, LNG, refining, petrochemical, and heavy industrial facilities throughout North America.
When performance matters, cleaning must be engineered - not improvised.
Heat Exchanger Cleaning
Restoring Thermal Efficiency at the Source
Heat exchangers quietly lose performance as scale, corrosion byproducts, hydrocarbons, paraffins, silica, and solids accumulate along internal surfaces. The impact is gradual but costly — declining heat transfer, rising differential pressure, increased fuel demand, and shortened run length.
Left unresolved, fouling drives instability across the entire system.
Valkyrie approaches heat exchanger cleaning as an engineering discipline. Every scope is developed around deposit characterization, metallurgy compatibility, hydraulic flow modeling, controlled chemical selection, and temperature optimization. The objective is not simply deposit removal — it is full restoration of heat transfer performance while protecting the asset.
Our advanced mobile chemical circulation systems deliver high-volume, controlled cleaning in hazardous industrial environments. Integrated heating, engineered flow control, and solids management allow us to remove complex fouling safely and efficiently while minimizing downtime.
The result is measurable performance recovery — improved approach temperatures, reduced pressure drop, stabilized pump loads, and extended operational run length.
Pressure Vessel Cleaning
Reducing Risk. Improving Reliability.
Pressure vessels in oil sands, SAGD, refining, and processing facilities accumulate sand, sludge, iron sulfide, corrosion debris, and hydrocarbon residues over time. Traditional mechanical cleaning methods increase confined space exposure and extend outage duration.
Valkyrie prioritizes engineered chemical circulation and non-entry strategies wherever feasible. By suspending and removing solids through controlled circulation systems, we reduce safety exposure while maintaining cleaning effectiveness.
Our methodology focuses on:
- Controlled solids removal
- Metallurgy protection
- Reduced confined space entry
- Minimized operational disruption
The outcome is safer execution and improved restart reliability.
Clean-in-Place (CIP) Programs
Proactive Asset Performance Management
Mechanical cleaning is reactive.
Clean-in-Place is strategic.

Our CIP programs allow controlled chemical circulation through closed systems — often without full disassembly — restoring hydraulic balance and thermal efficiency while significantly reducing downtime and safety exposure.
For facilities seeking to extend run length between turnarounds, reduce fuel consumption, and stabilize process conditions, CIP is not simply an option — it is a performance strategy.
Engineered Emissions Control Solutions
Our approach goes beyond administrative procedures—we deploy engineered systems that proactively manage emissions and integrate seamlessly with tank cleaning, vessel cleaning, and turnaround operations.
Closed-Loop Cleaning Systems
During robotic tank and vessel cleaning, our closed-loop methodology prevents vapors from being released to the atmosphere. All emissions are contained and processed within the system, ensuring maximum safety and environmental protection.
Mobile Vapor Recovery Units (VRUs)
Our mobile VRUs capture vapors directly from tanks or vessels, scrub contaminants, and recover hydrocarbons that can be returned to the client’s process. The result: reduced environmental impact and improved economic value.
Engineered for North America’s Industrial Environment
Our mobile chemical cleaning systems are purpose-built for hazardous area compliance, including Class 1 Division 2 environments. Designed to meet stringent North American regulatory standards such as ASME B31.3 process piping requirements. Our equipment performs reliably across extreme climates and high-risk operating environments.
From Western Canada’s oil sands to U.S. Gulf Coast refineries, Valkyrie delivers consistent, technically disciplined execution where production cannot afford compromise.
The Standard We Operate By
We do not approach cleaning as a service call. We approach it as a performance obligation.
Every project is engineered to:
