Refurbishing Power Transformers
-
A North American service provider specializing in power transformer refurbishment needed a precision-controlled blast cabinet to clean and prepare transformer components—such as radiators, end frames, and hardware—for re-coating and reassembly. The challenge was to deliver consistent, spec-grade surface finishes while handling a wide range of part sizes and surface conditions. The solution had to reduce manual variability, support high-volume workflows, and provide repeatable, traceable blast cycles aligned with utility standards.
-
Clemco worked closely with the customer’s maintenance and engineering teams to design a recipe-driven blasting system that could adapt to multiple transformer component profiles. The design process focused on:
Analyzing surface prep requirements for steel, copper, and alloy parts with varied corrosion levels
Selecting appropriate abrasive media and blast pressures to clean without damaging sensitive surfaces
Designing a multi-recipe HMI interface allowing operators to select pre-programmed blast settings for different components
Incorporating adjustable fixtures and part handling tools for safe and efficient changeovers
-
Clemco delivered a custom-engineered, recipe-driven blast cabinet, purpose-built for transformer refurbishment, featuring:
A user-friendly touchscreen HMI control panel with programmable blast cycles based on part type, material, and condition
Precision blasting nozzles and optional automation to maintain uniform surface coverage and finish quality
A media reclaim and dust collection system to maximize abrasive life and maintain a clean, safe work zone
Heavy-duty, adjustable part fixtures to accommodate transformer components of varying sizes and weights
Operator training and technical documentation to ensure consistent use and compliance with utility maintenance protocols
The result was a high-efficiency surface prep solution that enabled the customer to improve finish quality, reduce operator variability, and boost throughput—ensuring every refurbished transformer met performance and reliability standards before going back into the grid.

A contractor specializing in municipal infrastructure maintenance needed a rugged, high-capacity blasting solution to support the refurbishment of water towers across rural North America. These projects involved removing old coatings, rust, and scale from large steel structures—often in remote, elevated environments with limited access to utilities and tight project timelines. The customer required bulk abrasive capacity, extended blast cycles, and equipment that could perform reliably in tough field conditions without frequent refills or downtime.
-
Clemco collaborated with the customer’s field operations and project managers to develop a bulk blast system tailored for mobile, high-volume infrastructure work. The design process focused on:
Determining optimal pot size and abrasive flow control to sustain long, uninterrupted blasting cycles
Engineering for portability and ease of setup in remote, elevated, or confined job sites
Selecting wear-resistant components and corrosion-resistant fittings to ensure long service life in harsh environments
Incorporating safety systems, such as pressure-release valves, remote deadman controls, and OSHA-compliant hose configurations
Supporting multiple operator configurations to accelerate project timelines on large vertical surfaces
-
Clemco delivered a fleet of bulk blast machines built for high-efficiency, field-based water tower refurbishment, featuring:
6-cuft and 160-cuft bulk blast pots with extended runtime capacity for minimal downtime and maximum productivity
Multiple outlet systems for simultaneous blasting by two or more operators, increasing surface coverage rates
Heavy-duty skid or trailer-mounted units designed for rugged mobility and quick deployment
Integrated moisture separators, pressure regulators, and metering valves for precise abrasive flow control
Technical support, startup training, and maintenance guides to ensure safe operation and long-term reliability in the field
The result was a field-ready, high-output blasting solution that enabled the customer to refurbish water towers faster, safer, and more efficiently, extending asset life and improving infrastructure quality across underserved rural communities.
Water Tower Servicing
-
A civil infrastructure contractor tasked with refurbishing steel trestle bridges across remote, rural regions in North America needed a highly portable and reliable blasting solution. The project required the removal of rust, lead-based paint, and mill scale from structural steel under tight environmental controls and logistical constraints. Equipment needed to be lightweight enough for remote access, yet powerful and durable enough to deliver industrial-grade surface preparation in challenging, outdoor field conditions.
-
Clemco worked closely with the contractor’s field crews and project engineers to design a solution optimized for mobility, safety, and continuous operation in tough terrain. The design phase focused on:
Selecting a 6 cu ft blast pot size as the ideal balance between mobility and runtime
Outfitting the units with rugged pneumatic controls and remote deadman switches for safe single-operator use
Incorporating moisture separators and abrasive metering valves to maintain blast quality in humid or variable weather
Designing the units to be skid-mounted or wheel-mounted for easy transport across gravel roads, embankments, or rail lines
Ensuring compatibility with vacuum recovery or containment systems for lead paint compliance and environmental safety
-
Clemco delivered a fleet of 6 cu ft portable blast machines purpose-built for trestle bridge refurbishment, featuring:
Pressure-hold systems for extended blasting between refills, increasing field productivity
Durable construction with welded steel frames for impact resistance and stability in rough conditions
Precision abrasive metering to ensure efficient media usage and consistent surface profiles
Remote control and deadman systems to support single-operator safety and flexibility
Optional configurations for multi-operator setups or integration with on-site compressors and containment equipment
The result was a field-ready surface preparation system that enabled the contractor to work efficiently in remote bridge locations, meet surface prep specifications for repainting and structural integrity, and stay compliant with safety and environmental regulations.
