On-demand dilution packages built for facilities that regularly use sulfuric acid.Engineering? Done.
Your path to operation just got shorter. CG Thermal’s pre-engineered sulfuric acid dilution packages allow you to produce the concentration your process requires, right at your facility.
Each package integrates controlled acid mixing, heat removal, instrumentation, and controls, giving you a faster, more straightforward path to on-site dilution without engineering an entire system from the ground up.
A Complete Dilution Process—Engineered and Ready to Build.
Each package is designed and fabricated as an integrated sulfuric acid dilution system. The package includes:
- Plug-and-play modular construction with easy-to-access tie points to field piping and electrical
- Acid and water metering
- Controlled mixing and dilution
- Heat exchanger for removal of dilution heat
- Safety sensors and interlocks for safe, reliable operation
- Skid-mounted modular construction for simplified transportation and site integration
- Pre-programmed PLC and operator interface, with plant control-system integration available
- System design and fabrication
- Documentation, including P&IDs, equipment specifications, system drawings, and operating instructions
CG Thermal assembles and tests the system’s equipment, piping, instrumentation, wiring, and controls before shipment, helping reduce field work and provide a more straightforward path to installation and startup. Clearly defined connection points simplify integration with your facility’s acid supply, dilution water, cooling water, electrical power, and downstream process piping.

On-Demand Dilution. Lower Delivered-Acid Costs.
Facilities purchasing pre-diluted sulfuric acid may be paying a premium to transport both acid and water. By purchasing higher-concentration acid and diluting it on-site, you can produce the concentration your process requires while gaining greater control over your acid supply.
Benefits of Onsite Dilution
Produce only the concentration your process requires while improving the economics and flexibility of your acid supply.
- Lower acid purchasing and transportation costs
- Less diluted solution transported to your facility
- Greater control over acid concentration and availability
- On-demand production of process-ready sulfuric acid
Built for Facilities That Regularly Use Diluted Acid
Pre-engineered packages are designed for facilities with a recurring need for diluted sulfuric acid, including:
- Water and wastewater treatment facilities
- Pulp and paper mills
- Chemical processors, distributors, and blenders
- Facilities using sulfuric acid for industrial pH control
- Plants replacing purchased pre-diluted acid with onsite dilution
Expandable to Meet Your Needs
The core dilution package receives concentrated sulfuric acid and water, controls the dilution process, removes the generated heat, and delivers diluted acid at the required concentration. If your facility already has the necessary storage and transfer equipment, the package can be integrated with that existing infrastructure.
Need CG Thermal to handle more of the process? Optional tank and pump skids can be added upstream or downstream of the core package:
- Concentrated acid supply: Add a storage tank and feed pump to hold concentrated sulfuric acid and deliver it to the dilution package.
- Finished-product storage: Add a downstream tank to hold diluted acid until it is needed, along with a discharge pump to transfer it to the point of use.
- Additional product management: When required, a second receiving tank can provide separate storage for material that needs further adjustment before returning to the process.
Choose only the equipment your facility needs—or let CG Thermal provide a more complete acid storage, dilution, and transfer system.
Built for Sulfuric Acid. Built for Maintainability.
Umax SiC Advanced Ceramic Heat Exchanger
At the heart of each dilution package is a Umax SiC Advanced Ceramic heat exchanger. Its alpha-sintered silicon carbide tubes provide exceptional resistance to corrosion and erosion in demanding sulfuric acid service—and are backed by a lifetime guarantee against corrosion and erosion.
Umax is also designed for straightforward onsite maintenance. Individual tubes can be inspected, cleaned, or replaced with common tools without disturbing adjacent tubes or requiring specialized field welding—helping reduce downtime and simplify long-term maintenance.
Replace tubes as needed!
Frequently Asked Questions (FAQ)
What is a pre-engineered sulfuric acid dilution package?
A pre-engineered sulfuric acid dilution package is an integrated system that combines acid and water metering, controlled mixing, heat removal, instrumentation, and automated controls. It provides a defined starting point instead of requiring every dilution system to be engineered from the ground up.
Why dilute sulfuric acid onsite?
On-site dilution allows a facility to purchase higher-concentration sulfuric acid and produce the concentration its process requires. This can reduce the amount of diluted solution being transported, lower delivered-acid costs, and provide greater control over acid concentration and availability.
Can the package be configured for different acid concentrations and flow rates?
Each pre-engineered package is designed to operate within a defined range of acid concentrations, flow rates, and temperatures. CG Thermal will review your process requirements to determine whether they fall within the package’s operating parameters. If they do not, our team can design a custom sulfuric acid dilution system to meet your application requirements.
What information is needed to configure a package?
To get started, we’ll need your incoming acid concentration, required outlet concentration, production rate or daily usage, operating temperatures, available utilities, and information about any existing tanks or transfer equipment. If every detail has not yet been established, our team can help define the remaining requirements with you.
Can the package connect to my existing tanks and transfer equipment?
Yes. The core dilution package can be integrated with existing concentrated-acid storage, water supply, finished-product storage, and transfer equipment. CG Thermal will review the existing infrastructure and establish the appropriate package boundaries during application review.
Can tanks and pump skids be added to the package?
Yes. Optional tank and pump skids can be added before or after the core dilution package. Options may include concentrated-acid storage and feed equipment, finished-product storage and transfer equipment, and additional receiving capacity when separate product management is required.
Can CG Thermal provide a completely custom dilution system?
Yes. The pre-engineered package provides a faster, more standardized starting point, but CG Thermal can also adapt the materials, capacity, instrumentation, controls, tanks, and pumps—or engineer a fully custom sulfuric acid dilution system.
Why is a heat exchanger required for sulfuric acid dilution?
Mixing concentrated sulfuric acid with water generates significant heat. A properly selected heat exchanger removes that heat and helps the system continuously produce diluted acid at the required concentration and outlet temperature.
What type of heat exchanger is used in the package?
CG Thermal packages use a Umax Advanced Ceramic silicon carbide heat exchanger designed for demanding sulfuric acid service. Its alpha-sintered silicon carbide tubes provide exceptional resistance to corrosion and erosion while supporting efficient heat removal.
How is the dilution package delivered?
The package is assembled and tested at CG Thermal before shipment. Its integrated construction helps reduce field fabrication and provides a more straightforward path to site installation and startup.
What support is available after delivery?
CG Thermal offers ongoing engineering support, system inspections, preventive maintenance services, and assistance in identifying critical spare parts. Available services can be tailored to the needs of the installation.
Can the Umax heat exchanger be maintained onsite?
Yes. Individual Umax tubes can be inspected, cleaned, or replaced onsite using common tools without disturbing adjacent tubes or requiring specialized field welding. This field-repairable design helps simplify maintenance and reduce downtime.

Need Something Completely Custom?
We Engineer Those Too.
When an application falls outside the parameters of our pre-engineered packages, CG Thermal can develop a fully custom sulfuric acid dilution system. Materials of construction, capacity, target concentration, instrumentation, tanks, pumps, and controls can all be selected to suit the process.
