Hi, 

We have this Jeros dishwasher in our bakery. 

From memory it is this one.

http://www.jeros.com...c-24/c-69/p-133

 

They generate a lot of steam and there is an extraction system attached to it. It kicks in when the program is finished. 

There seems to be SO much condensation from the steam!!! It drips down and there ends up being a lot of water on the floor. 

 

I had suggested that maybe the exhaust should run WHILE the program is running, but production say this would remove too much energy. Thoughts anyone? Dishwasher experts come forward!

Hi, AJL;

 

 remove too much energy.

 

I'm not sure what you mean by this?  The steam definitely needs to be vented and adequate makeup air provided to prevent condensate.

Remove too much energy? Could you clarify?

 

If you mean it COSTS too much energy to run a fan to exhaust that steam during the cycle, then they just need to deal with it. The costs associated with poorly managed moisture are much higher!

 

If they're concerned that removing steam from the cycle would reduce the efficacy of the cleaning, they may have a point. However, the manufacturer of the dishwasher should have the final say in that. I would reach out to the manufacturer to see if it's normal that your system generates that much excess steam during the cycle. To me that doesn't sound right, your washing machine may have a faulty seal or something!

 

If the machine is working as intended and the manufacturer doesn't recommend running the exhaust during a cycle either, your next option would likely be upgrading the exhaust on the room itself. Installing an exhaust fan near the dishwasher could help with the steam.

A part of our consulting covers equipment and various types of equipment including these machines.

 

I am assuming there is no where for the condensate to go except the floor and the floor does not have a water drain nearby?

 

There is the first key - I have rarely seen one of these not located near a fixed floor drain.

 

If no drain i would go to the installer/purchase point and request if they have additional equipment that that can installed to combat the situation.

 

Just curious, where is the washer located? Most are in rooms that are dedicated to cleaning and sanitizing such as next to a 3-bay sink, etc. 

 

Also, I am not really sure why you are running into such a issue with a dishwasher, I would also be checking the condition of the machines internal thermal jacket if it has one or it is run in an Cool room,etc.

 

I do not believe you can re-program the machine to exhaust  like the way you are mentioning about the energy loss as this would effect the internal temperature of the machine.

 

I would however do an internal tab temp check to ensure it is within recommended temp range as it is possible the machine is super-heating water  and that could an additional issue.

Hi,
Thanks everyone. We have calibrated the probe. It is reading accurately.
The exhaust system is programmed to start when the machine has finished a cycle. I am not sure if this is standard or not.
The water comes up to 80degrees and the cycles runs for 6 minutes.
A lot of steam is generated in this time.
Glen- yes in a room dedicated to cleaning next to a sink. But the water does not run direo to a drain because of the floor slope.
Plus I would say the amount of water is excessive.
