55 Gallon Drum Line Equipped with Washlines, Ovens, Recuperative Thermal Oxidizer and Heat Recovery Methods
Executive Summary
Epcon engineered a fully integrated 55-gallon drum production line that includes washlines, curing ovens, a recuperative thermal oxidizer, and a high-efficiency heat-recovery system. The oxidizer not only destroys VOCs generated during washing and curing, but also recaptures waste heat to power the ovens, minimizing fuel consumption. This turnkey system enables continuous drum production with reduced operating costs, lower emissions, and a tightly optimized plant footprint.
Project Overview
A European-based drum manufacturer expanding into the U.S. sought to implement a complete production line for 55-gallon steel drums. They required integrated washing, curing, and emissions control equipment that could support continuous, high-volume output while remaining energy-efficient and environmentally compliant. Epcon delivered a full system including washlines, curing ovens, a recuperative thermal oxidizer, and a heat recovery systems engineered to reduce fuel cost and improve overall system efficiency.
The Challenge
The customer’s production objectives created several engineering and environmental challenges:
- High-volume drum production requiring a continuous flow process
- Need for integrated washing and curing prior to finishing
- VOC emissions generated from cleaning and coating processes requiring abatement
- Desire to minimize fuel consumption despite heat-intensive operations
- Limited facility space requiring a compact and efficient system layout
- Need for a fully integrated system designed to operate as a unified process
Engineering Requirements
The production line needed to accomplish the following:
- Provide washlines and curing ovens compatible with steel drum pre-treatment
- Include a recuperative thermal oxidizer (RTO) capable of treating oven and washline exhaust
- Recover waste heat from oxidizer exhaust to power portions of the curing and drying processes
- Support continuous production of 55-gallon drums
- Fit within a defined plant footprint with minimal external support systems
- Provide synchronized automated controls for washing, curing, emissions treatment, and heat recovery
- Maintain regulatory compliance while improving operating efficiency
The Solution
Epcon designed and manufactured a complete integrated 55-gallon drum finishing line, featuring:
- Washlines engineered for effective drum cleaning before curing
- Industrial curing ovens designed for drum drying, coating, or bake cycles
- A recuperative thermal oxidizer to treat solvent-laden exhaust streams and ensure VOC destruction
- Heat recovery methods that redirect oxidizer exhaust heat back into the ovens — reducing or eliminating the need for burner operation during certain cycles
- A continuous, synchronized production layout integrating washing, curing, emissions control, and heat recovery
- A compact design tailored to the facility’s footprint while maximizing production throughput
The oxidizer and heat-recovery system were engineered together to provide both emissions control and energy savings, allowing the customer to operate more efficiently than with conventional standalone systems.
Technical Specifications
Production Line Type: 55-Gallon Drum Washline + Curing Oven + Finishing System
Oxidizer Type: Recuperative Thermal Oxidizer (VOC abatement for washline and oven exhaust)
Heat Recovery: Waste heat routed from oxidizer exhaust to power ovens and drying cycles
Washlines: Integrated drum pre-treatment and cleaning system
Curing Ovens: Heated using recovered thermal energy where possible
System Integration: Continuous wash → dry → cure → oxidize → recover heat → reuse
The Results
The completed system delivered major operational and environmental benefits:
- Reduced fuel consumption through efficient oxidizer-to-oven heat recovery
- Effective VOC elimination via the recuperative thermal oxidizer
- Lower operating costs, especially in fuel-intensive curing operations
- Streamlined production flow, integrating washing, curing, emissions control, and heat recovery
- Compact system footprint, enabling the entire finishing line to fit within limited available space
- Higher overall system efficiency, supporting high-volume drum manufacturing with lower emissions and energy use
The customer achieved a fully compliant, energy-optimized, continuous drum production line engineered for long-term reliability.
