Elmadry Heater for watch parts? Too Hot??


Recommended Posts

Hi. I have an old Bulova Watchmaster ultrasonic cleaning machine that I have used for years. One thing that has always bothered me is the drying unit. While drying, the rinsing fluids drip into the guts of the machine. Very messy and I am always wary of potential ignition. 


Was looking for a dedicated dryer and came across the Elmadry series. A unit like the Elmadry TD30. Cousins has there here: https://www.cousinsuk.com/product/hot-cold-air-dryer-elma 

When the heat is on, these units dry at 70°C (158°F). That feels pretty hot to me. Looking for opinions or experience with this as a solution.

Regards,

Stu

Hi The essential thing is to get the parts dry safely and without loss. A dedicated drier (as Shown) is just an expensive piece of kit with a few bells/whistles and flashing lights.  The common hair dryer can do the same job with no fuss. Either keep the parts in the basket or decant them to a mesh container and gently blow dry with the dryer and save £350 for somthing you really do need.

Doesn't your machine spin-dry in the jar before going to the heater, like Elmas do?

No - not the watchmaster. The tanks are standalone - you manually move from US Wash to pre-rinse to US-Rinse. After the US Rinse I manually shake the basket to release some fluid and then it goes to the dryer, which does spin and heat (but the drips go into the machine).

I guess my question is really around the heating temp (is 70°C reasonable) - I agree the Elmadry is expensive but I can likely find something much cheaper. Also in terms of productivity and consistency I'm trying to avoid the manual blowdrying method (although I agree it would work). I have a workflow that I try to stick to - and I have tasks that I like to do while the dryer is running...

70 degrees does seem a bit hot though I use an old Pearl machine and the metal basket is too hot to handle after a cycle of a few minutes so it's probably doing a similar temperature. I will say I've run those plastic levers from Rego movements through the dryer without incident if that means anything. I expect if you go with the ElmaDry machine and you're concerned about the temperature you're going to have to plan to add some time for the added attention, and if you are then perhaps just go with something cheaper- the hair dryer, the warm oven. A food dehydrator runs in the 35 degree range...
