INDUSTRIAL DIP TANK WASHERS

Industrial dip tank washers are used for immersion cleaning of parts. Parts are submerged in a cleaning solution to obtain complete coverage of the part. The parts can be moved, typically vertically up and down, to cause agitation of the solution for better cleaning. The solution in the tanks can also be agitated through circulation, by pumping the solution from the tank and returning it to the tank through eductors. Dip tank washers are well suited for parts with complex geometry such as blind holes or pockets that would be difficult to reach with a spray type washer. Another example would be metal tubes that must be cleaned on the inside and the outside of the tubes.


Immersion cleaning is an option for parts that cannot be hung from a conveyor, or that could be damaged by other material handling methods employed in other types of washers. They are also suited for parts that require a longer solution dwell time than what would be practical with a continuous spray type washer. Typical applications of immersion cleaning by a dip tank washer would be removing cutting or forming oils, or general soils, prior to assembly or another operation such as a plating or coating process. Dip tank washers are used for immersion cleaning across many industries. Generally, the stages are wash and rinse, however the washer can be multi-stage to accommodate the processes required. Stages are heated as required using natural gas or propane submerged tube burners, or electric heating elements.

EFFICIENCY AND INNOVATION FOR DIP TANKS

Horizon Performance Technologies has the experience and engineering expertise to design industrial dip tank washers around the specific requirements of the immersion process. Each system is engineered to achieve the required part cleanliness and process results while supporting efficient operation. During the design phase, Horizon considers factors such as part geometry, material and weight, process chemistry, method of immersion, material handling, tank entry and exit angles, required dwell time, and whether the application requires batch or continuous processing. Evaluating these variables helps ensure the washer is properly configured for the application and production requirements.

HORIZON'S TANK-WITHIN-A-TANK DESIGN

For many applications, Horizon Performance Technologies can incorporate an innovative tank-within-a-tank design that helps maintain cleaner process solution around the parts being washed. The parts are immersed in an inner process tank that is filled from the bottom, allowing solution to continuously move upward through the work area. As the solution rises, it overflows from the inner tank into the surrounding outer tank, carrying floating oils and surface contaminants away from the parts. Because these contaminants are directed into the outer tank, parts are removed from the cleaner solution contained within the inner tank. This design can improve solution management, help reduce the potential for parts to be re-exposed to surface oils during removal, and support more consistent cleaning results throughout the process.

Horizon Performance Technologies maintains a strong focus on engineering detail and equipment quality throughout every phase of the project, from system design and fabrication through installation, start-up, and post-installation support. This comprehensive approach helps ensure the finished equipment performs reliably and delivers the process results required for the application.

Dip Tank Accessories

Filtering – SS bag filter housings equipped with isolation valves. Pressure feedback and filter cleanliness occurs when the optional pressure monitoring is included. This can notify the operator to maintain the filter and/or shut down the system if the filter is not changed and the system falls out of spec.

Oil Coalescer – used to process oil in two ways. The solution will be filtered and then will pass through oil separation before returning to the tank. The basic tank configuration has a solution capacity of approximately 45 gallons and is made of 14-gauge 304 stainless steel, welded water tight. The support structure also includes storage for the filter bags and placement of a 5-gallon pail for oil collection.

Water Treatment System - Complete Water Treatment Systems are available including:

• Carbon filter, FRP tank, brass control valve, for chlorine removal from city water supply.
• Duplex water softener, FRP tanks, water meter, salt tank with salt grid and safety shutoff float, for removal of mineral hardness from the water supply.
• Reverse Osmosis machine to reduce the incoming water total dissolved solids by 97-98%. Includes: low energy membranes, permeate and concentrate flow meters, concentrate and recycle flow control valves, high pressure pump, 316 SS membrane housings, automatic inlet shutoff valve, low inlet pressure switch, inlet and outlet sample valves, pre filter – post filter – primary and final pressure gauges, 1.0 micron pre filter, powder coated steel frame, and NEMA 1 control box.
• Transfer pump to continuously circulate the stored RO water and pressurize the water going out to distribution.
• Poly RO water storage tank. Includes flow controller with internal piping to continuously circulate and mix the RO water.
• Conductivity meter and sensor for remote monitoring of the stored water quality.
• UV light in 316 SS housing installed in the RO storage tank recirculation line piping, for bacteria kill.
