I've heard different stories about a coating that apparently has some kind of suface finish that punctures the bacteria cell wall when the bacteria comes into contact with the wall finish.
Any produt names or manufacturers you can think of?
Is this finish "PLASTISOL"? :confused:
Am now installing insulated panels with Plastisol finish that is EU approved finish for FRESH meat/fish storage rooms & processing rooms.
My customer commented that this is the ONLY (?) finish for EU certified processing plant.
Re: Positive air pressure system
Hi : Try an RSI pressure controller linked to an $85 variable speed motor control and a positive inline ventilating fan. Cheap(under $8000), effective, and as used for hospital SARS/TB negative pressure room controls with automatic pressure control and alarms. Remember to size the fan for any pressure drop that you will find across Hepa filters you install.

So Sorry, but that should have been a TSI controller, by the people who manufacture Alnor Balometers and also a full range of positive and negative pressure controllers.

I need to take this one step at a time and the above is important as the first point to conquer.
If the above cannot be tested then the rest will fail completely.
The area to be pressurised contains food make up area to inlude in this area are 1 x blast freezer, 1 x blast chiller, 1 x changing room, cook off area all with plaster board ceilings and dual discharge evaps for temp control of area.

If anyone is still interested in this topic, here is what we used:
TSI Pressura 8630 controller with 4-20 MA output(has visible display of pressure differential from the transducer) an inexpensive variable voltage fan motor controller similar to one available now as "Smartfan"from Control Resources, and a Soler Palau PV-200 Hi static pressure inline vent fan providing 485cfm at .25" static pressure.
