Pre-Engineered Thermal Fluid Systems vs. Custom Thermal Fluid Systems – How to Decide What You Need
# Pre-Engineered vs. Custom Thermal Fluid Systems: How to Choose the Right One for Your Application
Published by jforman on November 22, 2021, 8:35 PM | Leave a Comment
When it comes to selecting a thermal fluid system, both pre-engineered and custom-engineered solutions can meet your needs depending on the specific requirements of your application. This blog post will explore the differences between these two types of systems to help you decide which is the best fit for your project. While both options come with distinct advantages, understanding their differences is crucial for making the right choice.
## Pros and Cons of Each Type of Heating System
Before finalizing your decision, it's essential to:
1. Clearly define the unique performance requirements of your application.
2. Thoroughly evaluate the installation requirements and any specific facility needs.
3. Compare different thermal system suppliers to understand their product offerings and approaches.
4. Determine the proper installation and operational procedures for your facility.
It's important to note that errors made in these areas can significantly impact your project. For instance, failing to assess different heater designs or not taking the time to compare suppliers can lead to costly mistakes that are hard to fix once installation begins. Fortunately, Sigma Thermal is here to guide you through the process and ensure you make informed decisions regarding your thermal fluid system.
One of the key decisions you'll face during system selection is whether to go with a pre-engineered system, a custom-engineered system, or a combination of both. Below are some of the pros and cons of each type of system to help you make this critical choice.
### Pre-Engineered Thermal Fluid Systems
Pre-engineered thermal fluid systems offer several significant advantages:
- **Lower Capital Costs**: Due to a standardized bill of materials, these systems tend to have lower upfront costs.
- **Faster Delivery Times**: Since no additional engineering is required, these systems are delivered more quickly.
- **Clearly Defined Specifications**: All dimensions, drawings, and performance parameters are predetermined before purchase.
- **Streamlined Projects**: Reduced site or plant engineering expenses as there's no need for extensive drawing reviews, revisions, or approvals.
### Custom Engineered Thermal Fluid Systems
On the other hand, custom thermal fluid systems are often preferable for more complex applications or processes. You might opt for a custom system if you wish to specify certain factors, such as:
#### Process Considerations
When designing a custom thermal fluid system, consider the following process-related aspects:
- **System Flow Rates**: The rate at which the fluid moves through the system.
- **Fuel Types**: Including biogas, waste gas, liquid fuels, off-spec fuels, variable fuel compositions, or dirty fuels.
- **Emission Requirements**: Strict standards for emissions that must be met.
- **Heat Transfer Fluids**: Specific fluids like silicone-based fluids, molten salt, or ultra-high-temperature synthetic oils.
#### Review and Approval of Drawings
In some cases, you may wish to directly influence:
- **Connection Locations and Orientation**
- **Mechanical Specifications**: Configuration, materials, and paint choices.
- **System Components**: Specifying required instruments, valves, pumps, or other buy-out equipment.
- **Factory Interconnection and Skid Mounting**: Arranging components like expansion tanks, pump skids, heaters, and drain tanks on a single skid frame.
- **Custom Secondary Loop Skids**: For auxiliary systems such as indirect steam generators, temperature control units, control valves, and process coolers.
### A Hybrid Approach: Combining Pre-Engineered and Custom Components
At Sigma Thermal, we offer a modular approach to pre-engineered thermal fluid systems, allowing for the integration of both pre-engineered and custom-engineered components. This hybrid approach enables you to use pre-engineered components where customization isn't necessary while tailoring specific areas to meet your unique needs. For instance, you could use a pre-engineered heater and pump skid design but opt for a larger custom expansion and/or drain tank. This approach helps save time and costs while simplifying the system design to better meet project-specific requirements.
### Process Heating Systems from Sigma Thermal
