Funny enough, I have been to see one of our Clients this morning who is looking to add more screens to their equipment. Whilst on site, I took a photo showing how the kit benefits from the installation. This has recently been hit by a forklift and lived to tell the tale, great product.

Trevor C - Clever Engineering

Great company to deal with, we use RAB on a regular basis as they know and understand the industry very well.Highly recommend their services.

Simon Dennis - Blue Sky Cooling

our customers are very impressed with the quality of this product. The amount of dirt that the mesh filters collect is clearly visable, thus saving the coils from constant cleaning. The mesh is easy to clean and remove.
