subject: Acid Cleaning Systems - Vertical Tube Wash, Horizontal Tube Wash [print this page] Two acid cleaning systems used for quartz tube are popular in the wet process industry today. These are the vertical tube wash and the horizontal tube wash. I have listed below some of their features as well as their benefits for their specific uses.
Vertical tube wash - this particular acid cleaning system has the following features and benefits:
Proprietary nozzle - for conformal etch
Separate HF and Nitric acid tanks - used for blending
Pre-mix reservoir, including DI water mix
Recirculated blend of acids - for extended life
Concentration monitoring available for spiking
Vertical tube wash - the cleaning process
This is an acid cleaning system for quartz tube. Acid is sprayed from an onboard reservoir. Two holding tanks are incorporated to the system - one for HF and one for nitric. Other alternative chemistries can also be used, depending upon the contaminants. The chemicals used can be metered in to a pre-mix reservoir incorporating a DI water mix. This blend is mixed and pumped to a spray manifold and recirculated through a filter for extended life.
Notable features:
Embedded software - the system features data logging and trending as well as multiple recipes and security levels.It also provides real-time tank levels, drain conditions, and pump status.
Concentration monitoring system - this is used to measure the chemistries and allows for spiking of the reservoir with one or both chemistries.
Programmable system - vertical tube wash can be programmed to allow a mixture of chemistries, incorporated to a 3-step process: light etch, rinse, and dry. Further, this cleaning system is designed to reduce chemical and water use as well as effluent costs.
Control panel - is designed to have an ergonomically located color touch screen and with a user-friendly graphical user interface (GUI).
Horizontal tube wash - this is designed to cater large tubes and rods and usually comes with a magnetically coupling drive design, which is aimed to eliminate potential hazards from acid splash or leaking seals. This comes in a size that meets your needs and can either be a manual or fully automated system.
Twin chambers, for rods or tube combinations
Automatic cycles
Heavy-duty rollers
Up to 250mm Outside Dimension (OD)

Finding a good manufacturer - tips
There are some considerations you need to take into account to increase the likelihood of finding the best manufacturer in town. First, research plays an important role - make use of local directories as these are a huge repository of information about local manufacturers. Reading reviews from previous and present clients is also recommended.
