The theater experience in the huge Imagination 4D Theatre at LEGOLAND Malaysia includes a number of special effects including water spray. The theatre has carpeting and fabric covered seating.

​With the climate in Malaysia being hot and humid, and the interior being dark, the inside of the theatre has begun smelling musty and of mildew.
 
We installed 2 model UV SG-HVAC2350A Adjustable Output Ozone Generators in the air-conditioning ducts on each side of the theatre. They are timed to go on and off daily with the air-conditioning system.

The adjustable output feature allows us to very precisely regulate the amount of ozone introduced into the theatre, inserting just enough ozone to destroy the odours during the shows, while leaving no residual ozone behind. 

After the first 4 hours of operation, the interior of the theatre smelled fresh and clean again. These units have run for 2+ years without maintenance.

Last month, after 2+ years of operation, LEGOLAND replaced the UV Tubes with new tubes.
