Designed to perform KVR’S Radiator are designed to perform under working conditions -50degree up to 90degreeand a variation of pressure from 0.5 up to 2.0 bar KVR’S intercoolers are designed to perform under working conditions -50degreeup to 180degreeand variation of pressures from 0.5 to 2.0 bar(g), Our truck intercoolers are made entirely of aluminum. The specially –cut side panels resist the stress caused by high temperatures. Moreover. KVR’S Radiator plastic tanks are reinforced and made of plastic containing at least 30-35% fiber glass. The materials type is always indicated on the tank surface. No recycled plastics are used in our tanks All KVR ‘S Truck intercoolers are welded,using a special technique which ensures that the welding seam is very strong and more durable than traditionally welded intercoolers.
