Humidity Control - Woodworking

How to keep milled wood storage moist, your wood straight and crack free.

Small portions of large woodworking facilities can be humidified effectively without humidifying the whole plant.

Let's say you have a small area in a large plant where wood is to be stored for a short period of time before it goes to production. These may be freshly milled pieces with very precise dimensions.

In the dead of winter humidity control can be important. Humidity levels get very low. 12 to 15% relative humidity is not uncommon when outside temperatures approach zero fahrenheit (-18 celsius).

12% RH is dry enough to scrap a milled peice of wood in as little as 4 hours.

Just a small amount of higher humidity air around that wood can keep it within tolerance. Keep production on schedule and waste to a minimum.

Let's look at an application and put a system together.

Remember, this is not rocket science. This can be done by individuals with some machanical and electrial experiance.

I am here to step you through the process.

When considering humidity control for a woodworking area you may be misting 24/7 for as many as 5 months. What this means is you need a reialble long lasting pump system. A continuous duty rated pump.

These pump systems are of hgh pressue design using postive displacement pistons. That is the only way to get the pressure up to dersired values, over 400 psi.

The only way to get a pump systems to last for years is to slow the pump rpm down. This means oversizing the pump. I typically shoot for 20 to 30% of rated rpm.

Good reasons -

1. Pump mechanical ware is reduced considerably.

2. Pump oil change time frames can be extended.

3. If more capacity is needed, you have it.

4. Noise levels are reduced.

Say you have a storage area that is 100 feet x 200 feet with milled stock peices.

The stock peices are in carts on wheels and stand about 4 feet high. The carts are in rows for manoverablility. The ceiling height is 15 feet to the bottom of the deck.
