Modulating Dual Fuel Indirect Fired Heater

The Modulating Dual Fuel Indirect Fired Heater is a high-capacity, modulating indirect-fired heater engineered for industrial and commercial applications. This heater provides reliable, efficient, and safe temporary heating while meeting stringent certifications such as cETLus and CSA 2.14/ANSI Z83.7. 

As a Mechanical Design E.I.T. I played a pivotal role in bringing this product to life by contributing to its mechanical design, structural design, control panel design, and programming.

Mechanical and Structural Design

I developed the mechanical and structural design for the IAQH-1000, ensuring durability, portability, and compatibility with industrial environments.

• Designed the frame and skid base to support high operational loads and facilitate easy transportation.

• Used advanced engineering tools like Finite Element Analysis (FEA) to verify structural integrity and ensure optimal material usage.

• Collaborated with manufacturing teams to streamline assembly processes for faster production.

Control Panel Design

I designed the control panel in compliance with UL 508A standards, integrating key components to enhance usability and safety.

• Selected and configured the Watlow FAT controller for precise temperature modulation and safety monitoring.

• Incorporated user-friendly interfaces and safety features, ensuring reliable operation in field environments.

• Supported assembly and testing of the control panel, meeting certification requirements and operational benchmarks.

PID Programming

I developed the programming for the heater’s PID (Proportional-Integral-Derivative) control system, enabling advanced burner modulation.

• Optimized temperature regulation to maintain consistent heat output under varying conditions.

• Improved fuel efficiency by fine-tuning the control parameters, reducing operating costs for end-users.

• Enhanced reliability by integrating fail-safe mechanisms and diagnostic capabilities into the controller logic.

Dual-Fuel Design

I designed a dual-fuel system to allow seamless switching between natural gas (NG) and propane (LP), offering versatility across various deployment scenarios.

• Designed the fuel system and air-fuel mixing mechanisms to accommodate both fuel types.

• Programmed safety features to detect fuel type and automatically adjust operating parameters.

• Worked with vendors to select and test burners compatible with dual-fuel operation.

Alternative Fuel Design

I designed an alternative fuel system to allow easy switching between from the Dual-Fuel Design to a Diesel-Fuel Design.

• Designed the system to except a Diesel Burner.
