Ducted Exhaust System

[Golestan]

Hi,
Does any one have information or experience for heat removal by ducting the exhaust (hot air only) of a few machines. Each machine has a cooling fan and the heat comes out of a grill on the side of the machine where I can collect the out flowing hot air. Is there a collecting system we can just buy. The hot air will be sent to out side the building. This air is clean and no filteration is needed.

Regards,

Sounds like an ideal application for a small HRV (heat recovery ventilator) if you are in a cool/cold climate. You'd have to install sheet metal ductwork to connect the exhaust points up into a main exhaust trunk duct, then the HRV can provide pre-heated outdoor air as make-up air if you are in a cold climate.

If you are not in a cold climate then you'll have to buy an exhaust fan, design some exhaust ductwork, and get the thing installed. You still need a source of make-up air to replace the exhausted air.

If you take air out, you will have to put air back in.

Heat recovery is a good idea.

Look at the "Industrial Ventilation" handbook to obtain some basic guidelines

Go to a local HVAC contractor. There won't be an 'off the shelf' system you can just buy but there should be nothing difficult about getting it designed and installed installed.

Depending on the airflow, temp of discharged air, etc, a Nederman exhaust extraction arm is an ideal "off the shelf" system, that allows the exhaust system to be swung out of the way when working on the machine. Web-search on Nederman.
