RAMCO is a third generation privately owned and operated company over 75 years in business offering a complete line of cleaning and degreasing systems. Systems are manual or fully automated and can accommodate water based or alternative solvent based processing routines.
RAMCO has been in the business of building immersion washing systems since the 1940s with thousands of machines in the field. An experienced and dedicated staff has remained with the company over the years. Learning from a long span of experience and service, successes and failures, we have honed the most dependable long-lasting engineering designs and manufacturing formats. It is common to find RAMCO washers 20 or 30 years old still running. They are indeed built to last.
RAMCO systems are used for a multitude of applications including critical in-line cleaning and high production processes where downtime is unacceptable such as aerospace, automotive and medical. Each system is built for dependable repeatability of function. They are up and running, there when you need them. And a RAMCO network of local support is there for you, backing up the product, a constant presence.
A key expertise at RAMCO is the ability to incorporate a number of distinctive washing features into a single system. By doing so we achieve results on difficult to clean parts where other systems fail. At the heart of the RAMCO system is the adroit use of an elevator within each processing chamber. The elevator is used to transport components into and out of each chamber. However, its most important function is to position and move the components producing changing flow patterns within the working zone(s). We call this Dynamic Flow Combination. It is this aspect of function that allows RAMCO systems to achieve better coverage of component surfaces, superior results and accelerated washing, rinsing and drying cycles.
At RAMCO, we believe that our specialized know-how, spanning over 75 years in this industry, is a valuable asset to any customer. To that end, we’ve invested considerable time, effort and commitment into establishing, training, and maintaining an outstanding distributor network. These men and women are cleaning specialists experienced in process development, equipment selection, chemical selection, wash and rinse water treatment, installation, training, and support.

Our business is manufacturing the best immersion parts washing systems in the industry designed to meet a wide variety of applications from simple to demanding cleanliness, cell washing to final in-line precision cleaning. Our philosophy is that personal health, safety and the environment come first and there can be no compromise or question when it comes to safeguarding these concerns. Therefore, our focus is on engineering our systems to use modern aqueous cleaning agents or preferred alternative solvents and to replace toxic solvent degreasing.
The automation includes a zero pressure power feed conveyor to stage feed and position four carriers at a time. Lateral transfer through the cleaning stages is accomplished using RAMCO's patented RamTough articulating walking beam (see RAM TOUGH Automation). Each stage includes a transport elevator that gently takes carriers into and out of the processing zone and slowly agitates the workload during the process (see Dynamic Flow Combinations). An automatic unloading conveyor is placed at the end of the line with the capacity to hold four clean and dry carriers. Controls include an operators control panel with Allen-Bradley SLC500 for running the automation.
Each stage includes easy to use digital cycle timers and digital temperature controllers. The system includes high powered sweep frequency ultrasonics with Ramco's MultipleRollover system (see Dynamic Flow Combinations), large capacity filtration, dual cascading DI rinses and a doudle capacity hot air knife blow off dryer for rapid drying without excessive heat (see RAM TOUGH Dryers). Automatic covers are included to reduce emissions and save on energy.
This system was designed and built for Areva for cleaning parts that go into nuclear fuel rod assemblies. The components are precision washed and rinsed to a high cleanliness level under strict guidelines. The system is fully automated using RamNet. Critical operating functions such as temperature and water purity are tightly monitored within high/low limits. A fault alarm and system interrupt mode is automatically activated if functional parameters are not maintained.
The cleaning system provides powerful turbo/agitation washing with high intensity ultrasonic cleaning using RAMCO MulipleRollover to repeat the dual mode process for a number of preset “rollovers”. Multiple recipes for agitation washing and ultrasonic cleaning phases are provided.
RamNet is a state-of-the-art network of microprocessors. Each stage has its own microprocessor installed and internally wired to all local devices to power-up and run that stage. The microprocessor controls the timing, sequencing and all solenoids relating to covers, elevators, pumps, ultrasonic generators, heat on/off, and temperature. Each microprocessor is connected with twisted pair to the adjacent electrical box on the adjacent stage. The entire system is connected to a central Ethernet hub. In this way all microprocessors are connected with one another. The main CPU is located in the Operators Control Station (above right and below). This system uses Allen-Bradley MicroLogix 1100 PLCs in Ethernet configuration with operator interface through a PanelView Plus 1000 touchscreen (below). A cable modem is provided for Internet hook-up.
The advantages of RamNet are quickly realized:
RAMCO has extensive expertise in the design, engineering and fabrication of paint stripping systems. This Case History is based on replacing a toxic solvent paint stripper with an environmentally safer aqueous based stripping process. The modern process requires greater capabilities on the part of the overall stripping system. Specifically, the equipment has to provide greater mechanical agitation and filtration to get the desired level of cleanliness.
The system consists of a large paint stripper that can handle a 70" long x 36" wide x 24" high basket with a gross weight of 2000 pounds. An automatic opening and closing cover and a lip vent exhaust system are included. The cover and exhaust system are integrated with the transport elevator. The system is designed to energize the exhaust when the cover opens and shut the exhaust off when the cover closes
The paint stripping process uses platform oscillation and TurboFilter to provide sufficient mechanical agitation and filtration. The system incorporates large capacity duplex filter canisters and a vertical immersion pump. The photo above shows the surface activity of the turbulation system. The solution movement of the turbo is designed to flush away paint residues and to continuously apply fresh chemical to newly exposed layers of paint, thereby speeding the entire action. The flow is variable and can be adjusted so as not to disturb a surface seal (if required).
The main controls are mounted in a Nema 12 panel (see below) with lockout-tagout disconnect, digital indicating temperature controller and digital cycle timer with start/stop push buttons and process control selector switches. The system is electrically heated.
This Tube Washing System is designed for washing, double rinsing and drying complex automotive tubing in large quantities. The tubes are batched in racked lots of 50 per load. Up to four racks are loaded onto a power conveyor that advances and selectively feeds each load into the system. The operator simply presses a start button on the remote control panel and the system takes over from there. The transfer system employed uses multiple arms to allow for simultaneous indexing of baskets.
The photo below is shows the front of the machine with racked tubes, power feed conveyor, and remote operators control pedestal.
The machine is built using modular RAMTOUGH construction with Nema 12 panels provided at each stage for ease of diagnostics and maintenance. Nothing is placed underneath processing tanks or tucked behind “access” panels. All valves, pumps, filters, cylinders and heaters are located where they are accessible, clearly visible for inspection and easily serviced. RAMCO systems are designed for continuous production in industrial applications.
The heart of each system is the adroit use of the elevator within each processing chamber. The elevator is used to transport components into and out of each chamber. However, its most important function is to position and move the components within the working zone. It is this aspect of its function that allows RAMCO systems to achieve superior results in washing, rinsing and drying. We call this Dynamic Flow Combination. The effect of Dynamic Flow Combination is better coverage of component surfaces, more consistent results and accelerated processing times.
The RAMCO Caustic Leaching System has been used by many companies over the last 20 years for the removal of shell residues after investment casting. The system uses a highly concentrated bath of KOH or KOH/NaOH (approximately 35 to 50 percent) at temperatures close to the boiling point for the solution (approximately 230 to 250 degrees F) to slowly break down fused silica shell residues from investment castings. Although the process is slower than a molten caustic salt bath (normally operating at 1000 degrees F and 100% caustic) it is much safer and gentler to the castings and environment.
The unit above is designed for a 2000 pound load and a volumetric footprint of 45"L x 30"W x 15"H. It has a 255 gallon capacity and includes a lip vent exhaust system. The tank is built of heavy gauge stainless steel with exterior stainless steel insulation panels. A Nema 12 rated electrical enclosure includes selector switches, pilot lights, digital indicating temperature controller, digital cycle timer and lockout-tagout disconnect switch. An automatic opening and closing cover is included to reduce emissions and save on energy. The elevator is made from heavy wall stainless steel structural tubing. The tank is double V pitched for ease of cleanout and electric heaters side mounted to keep away from the slurry that forms at the bottom of the tank.
A larger RAMCO Caustic Leaching System is shown below. It has a load capacity of 1000 pounds and a working volume of 56"L x 31"W x 27"H with a 475 gallon solution capacity. This system also includes a V pitched bottom and a side mounted settlement chamber. A automatic pneumatic cover is sequenced with the automatic cycle timer and process cycle.
RAMCO Caustic Leaching Systems can be arranged for multi-stage processing as shown in the six stage line below. The system includes three caustic leach tanks two rinse tanks and a hot air knife blow-off dryer. Designed for high throughput this line includes a roll-around cart for front load/unloading of baskets. Each stage has a load capacity of 1000 pounds and a working volume of 36"L x 32"W x 12"H. All tanks have pitched bottoms to facilitate cleanouts. The covers are sequenced with the automatic timers controlling the process cycle.
Special features include front mounted controls, flanged mounted heaters, and a combined cascading rinsing and water make-up system (not shown) that conserves water while automatically keeping all leach tanks at the correct operating levels.
