Medical device cleaning presents a unique set of challenges. Extremely rigorous cleaning standards are maintained for instruments used in surgery, medical and dental procedures, as well as devices used as medical implants. While these devices often have difficult to clean features like blind-holes and designed-in porosity, they also have the most stringent requirements for disinfection and sterilization.

The conventional approach to sterilization of medical devices has been the use of high-pressure steam or vaporized hydrogen peroxide (VHP). When medical devices are inadequately cleaned however, residual soil can effectively seal in contamination, actually preventing proper disinfection and sterilization. Thus, a capable and robust precision cleaning process is the pre-requisite for sterile device manufacturing.

The unique characteristics of ultrasonic cleaning make this automated cleaning method ideal for medical device cleaning. The ultrasonic cleaning process has been demonstrated to be more effective than other types of cleaning, and is also safer, more repeatable, and more efficient than manual cleaning. Ultrasonic cleaning systems easily and thoroughly remove a wide range of debris from medical devices without damaging the part substrate.

UnitechCleaning Technologies Group, LLC (CTG) is excited to announce that it has partnered with Unitech Washing Systems Limited out of the UK to distribute specialty washers to the United States for the food and beverage industry.

When looking for an alternative to environmentally harmful parts cleaning solvents, manufacturers have turned to aqueous parts cleaning methods, including ultrasonic parts cleaning. In this post we’ll provide an overview of both aqueous parts cleaning and ultrasonic parts cleaning, and what to consider when choosing a parts cleaning method.

What is Aqueous Parts Cleaning?

Aqueous parts washers offer the cleansing power of solvent-based parts washing but uses water as its primary cleaning agent. Solvents can be used with the water in aqueous cleaning, depending on the parts cleaning requirements. These may include things such as emulsifiers, Inhibitors, anti-foaming agents, PH buffers, and more.

The determination of the most effective aqueous parts cleaning approach for a given application begins with the following questions:

  • What parts are being cleaned?
  • How detailed are the parts?
  • What materials are involved?
  • What is the production time allowance?
  • What are the customer requirements?

From there, the best equipment technology can be selected. Methods of aqueous cleaning can involve immersion or soaking, standard and high pressure spraying, or ultrasonics.

The process of recovering used diesel engine components and machining them to a condition that meets or surpasses OEM quality is called diesel engine remanufacturing, or as it is commonly known in the industry, diesel reman. Diesel engine remanufacturing does not repair or rebuild parts from a point of failure but rebuilds them from the core part to include engineering updates that meet new and improved standards.

Growing Demand for Remanufactured Parts

The automotive and diesel parts remanufacturing market is expected to see steady growth to the year 2026 according to market research firm Persistence Market Research. This anticipated growth in demand is due to the increasing need for cost-competitive remanufactured diesel engines, as well as expanding automotive fleets and increasing per capita spending power. According to the study, the global auto parts remanufacturing market is estimated to grow at a CAGR of 7.1% during the forecast period.

Remanufactured diesel and automotive parts are manufactured to precision standards and tested to assure that they meet or exceed the required specifications. The entire process follows an established protocol and is fully documented.


Manufacturing processes have become more technologically driven as today’s systems and equipment have evolved to higher levels of sophistication. These advancements have meant less downtime and greater productivity with higher levels of precision and quality. The parts cleaning industry is keeping pace with this trend by offering cleaning equipment that provides enhanced features and sophisticated control technology.

This advancement in parts cleaning equipment can be seen in the newest generation of cleaning systems from Ransohoff and Blackstone-NEY Ultrasonics divisions of Cleaning Technologies Group. CTG is a global supplier of the most innovative industrial and precision cleaning technologies available today. CTG is a leading manufacturer of aqueous based parts cleaning systems including: spray, immersion, and ultrasonics, in both standard and custom designs, as well as a complete line of recyclable aqueous chemistries and waste minimization technologies.

Ransohoff and Blackstone-NEY Ultrasonics offer a wide range of technology-driven parts cleaning equipment. Examples include:

Ransohoff, a division of Cleaning Technologies Group, LLC, is proud to introduce an innovation in a spray and ultrasonic combination aqueous parts cleaning system. The new Rotosonic (Patent Pending) will clean heavily soiled parts in a single machine, rather than having to purchase a spray cabinet and an ultrasonic machine separately. This new machine gives the ultimate in flexibility, allowing utilization of a single process or both processes, depending on your needs. The machine has a compact design and eliminates the manpower needs as well as the safety risks of moving parts from washer to washer.

The new Rotosonic is the ideal parts cleaning machine for re-manufacturing of automotive, truck, aerospace parts and more. The machine has a payload of 300LBS and a load height of 39”. The ultrasonic tank offers 40KHZ frequency to help clean the hard to reach locations and blind holes. The Rotosonic has a small footprint of 55” deep x 50” wide x 86” high.
