Q: I need a part for my dryer that is down! Can you help me?
A: Yes! If you get us a purchase order by 5PM CST we can normally get you a replacement part overnight directly from the factory. Exceptions are HEPA/ULPA filters, pre-filters, and custom built stainless steel components.
Q: My dryers are taking up to twice as long to complete a load as they should be.
A: Often, longer than normal dry times are the result of over-loading a clean room dryer. While our tumblers are nominally sized by pounds per load, for cleanroom use the dryers must be under loaded. Airflow is the key to a successful clearoom dryer load, and overloading coupled with the reduced airflow that comes with HEPA or ULPA filtration can severely increase load times. For a 170lb tumbler, we suggest loading no more than 100-115lbs of garments into the dryer. While we understand you are “losing” 55-70lbs per load, you are better off with a 33% decrease in loads but keeping the standard dry time than a 100% time to dry increase. If reducing the load size does not
Q: My tumbler is gas and utilizes the Honeywell™ temperature control and 2-stage gas valves and the dryer is either not getting hot enough or it is getting too hot and shutting off the flame; either way, we are experiencing longer than normal dry times as a result.
A: Alter the set points higher (in cases of not enough heat) or or lower (in cases of heat getting too high) by 2-3 degrees at a time until properly calibrated. Call us for further support.
Q: My tumbler is failing particle count tests! Help!
A: This can be the result of failed filters, too long between cleanings of the lint compartment or turbo box, or, in rare cases, a failure in the seal of the heating assembly (filter housing to transition, etc). The magnahelic gauge will tell you if pressure has dropped in the transition and the filters have failed, but a monthly visual inspection is the best way to ensure the filters are maintained. You should be changing the pre-filters monthly, which offers a great opportunity to inspect the top of the HEPA or ULPA filters. It is also a good idea to clean the lint compartment at the same time you clean the cleanroom (weekly/monthly per company SOP), and the turbo box whenever possible. Do NOT caulk, glue, or screw the lint panel onto the tumbler!Permanently shutting the lint compartment will allow it to build up more particulate than you can imagine. These particles will find a way into your product, and particle counters. As clean as the incoming air is, 80% of microscopic particles in garments are removed in the drying process. Just like particles build up inside the cleanroom by the end of a production week, so will they build up in the lint compartment and turbo box of the tumbler; a thorough cleaning is needed at least once a month, preferably once a week.
Q: My filters are failing, can I repair them or patch them up?
Q: Can I use silicon hi-temp caulk to patch up the seal?
A: In short: No. If you are running a Class 10,000/ISO 7 cleanroom laundry it may be permissible to use silicon caulk depending on the product. If you are a painter, or contracting laundry services with any painting services, even one particle of silicon will ruin and automotive paint job- costing your customer, and potentially you, a huge amount of money. For class 1000/ISO 6 and up, To save this hassle, we can provide you with silicon free Viton rubber caulk. Contact us for more information.
Q: My problem is not here or I’ve tried all these and I’m still having trouble!
