High-quality blast resistant doors in a highly efficient construction of steel and reinforced concrete. The mounting combines surface mounting and in-wall mounting. It is a side-hinged, swinging-type door (left hinged or right hinged). The door, also referred to as a blast proof door or an explosion proof door, can be manually operated from inside and outside for opening and closing.

Blast Valves are used for wall installation and are used for tunnelling protect, petrochemical industry, powerplants, VIP shelters, civilian shelters, military shelters and industrial shelters
High efficient shape of the gouge elements guaranties over 9000 m3/h flow inwards and 6000 m3/h flow outwards at pressure drop of 300Pa
Components are made from structural steel and hot deep galvanized steel
The valve is tested with long duration nominal peak reflected overpressure of 41 bar and short duration blast load reflected impulse density of 60 bar ms in the first 5 ms
The blast valves come in a size with a 350 mm diameter and lengths ranging from 650 mm to 2000 mm
The Blast Valves can also be customised according to customer’s requirements
Details
Wall Sleeve are designed for passing electrical cables of different sizes through a wall
It is commonly used in shelter construction characterized by blast resistance and gastight solution
The modularity is the most important advantage of the wall sleeves
The wall sleeve is tested with multiple nominal peak reflected overpressure of 41 bar at Fraunhofer Institute, Germany
It is used for tunnelling protect, petrochemical industry, powerplants, VIP shelters, civilian shelters, military shelters and industrial shelters
The sleeves provides a corrosion-resistant sealing for wide range of cable gland sizes
They are designed to be suitable for 200-3000 mm wall thickness
The cover plates are designed for various sets of cable glands can be customized
The diameter of cable can vary from 6 to 62 mm
Details
Wall Pipes are custom passages in walls created for water pipes that transport both clean water and wastewater
It is commonly used in shelter construction characterized by blast resistance and gastight solution
The modularity is the most important advantage of wall pipes
The wall pipe is tested with multiple nominal peak reflected overpressure of 41 bar at Fraunhofer Institute, Germany
It is used for tunnelling protect, petrochemical industry, powerplants, VIP shelters, civilian shelters, military shelters and industrial shelters
The wall pipes are available in various sizes, including diameters ranging from 25 NB to 100 NB, and lengths of 750 mm, 1000 mm, 1250 mm, and 2000 mm. These valves are designed to fit in a wall with a thickness range of 200 mm to 3000 mm
