Modulating Indirect Fired Heater

Overview

The Modulating 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.

Design

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.
