Good Morning,
Holonyak lab used a cleaning service until 2021. It was never a good solution. We continually had item lost, damaged, mixed in with our returns and lost/damaged shipments. On top of that the manpower it took to manage the shipping deliveries and inventory moving around does not pay off. We ended up buying a quality top loader washer with a SS drum. We also ended up installing a small but effective RO on the water supply line, a bag sealer, properly sized bags, and a set of nice SS racks. We hang the cleanroom suites up to dry on the racking in the same space as our washer. Our washing machine is in a storage room which is within our clean room. As the garments a not porous there is little to no water, they dry quickly. We also bag them for storage till they are required for swap out. Our losses have gone to near zero and we feel there is a better product provided to our cleanroom users. As we already owned our garments it was a no brainier. Our lab assistants process the laundry in the evening. We were spending thousands just for laundry services a year. On top of that the loses, damages and shipping were all recouped in a matter of months. Granted you will need a little assistance from the staff but it is worth it.
Hope this helps.

Good afternoon all,
Here at the University of Michigan/LNF we've been using launderable garments for many years (Cintas is the provider). We've had mostly good success, and our vendor has helped us to incorporate a simple suit modification to allow for better identification of individuals when they are in full garb. As part of our due diligence for keeping costs under control, we'd be interested in comparing notes with other Universities that are also using an outside company to provide your laundry service. Currently our laundry costs run us about $52K/year and we're laundering roughly 500 pieces of clothing every week.
Thank you,
Dennis Schweiger

Subject: [labnetwork] TemEbeam beam coil issue
Message-ID: <40961868.681113.1695232754487.JavaMail.zimbra@magnet.fsu.edu>
Hello All,
We have an issue with the coil current for the e-beam evaporator and wondering if somebody had a similar problem in the past. We suspect that it is related to the controller.
We have noticed an issue with the lateral beam sweep coil current in the Temescal TemEbeam controller (EBC). When the controller is turned on, the lateral beam sweep starts out at a high current of ~3-4 amps and is unable to be lowered using the lateral/latitude sweep position controls. This high current appears in the negative (left) region of the sweep pattern display area. We have checked the leads from the sweep coils up to the end of the connector attached to the ?Sweeper Coils? terminal at the back of the controller, and no issues were found. We have also tried a full factory reset of the controller as well as unplugging/plugging in the power cable at the back, but the high current issue still remains.
Any advise would be greatly appreciated.
Sincerely,
Alexey

At UW-Madison we have done something similar. We have a SS industrial washing machine hooked up to RO water and an industrial dryer with HEPA filter. We pay student hourlies to do the laundry, fold it, and put in gown room racks. With laundry detergent and student hourlies we are probably under $1K a year on garment logistics.
