A clamping device includes two end plates, disc springs, a grid of pistons, and tension rods. Each of the two end plates defines a plate area located within a perimeter thereof. The clamping device has piles of disc springs arranged as a grid of springs threaded on respective ones of the grid of pistons. The piles of disc springs is distributed and supported over the plate area on one of the two end plates. The grid of springs is positioned inwardly from the tension rods. The grid of springs is positioned to distribute clamping forces on one or more flow module plates, on one or more reactor plates, on one or more heat exchanger plates or on combinations of one or more flow module plates, one or more reactor plates, or on one or more heat exchanger plates, which plates are placed between the two end plates.

1. A clamping device comprising: two end plates, disc springs, a grid of pistons, and tension rods, each of the two end plates defining a plate area located within a perimeter thereof;piles of disc springs are arranged as a grid of springs threaded on respective ones of the grid of pistons, the piles of disc springs being distributed and supported over the plate area on one of the two end plates, the grid of springs being positioned inwardly from the tension rods, the grid of springs being positioned to distribute clamping forces on one or more flow module plates, on one or more reactor plates, on one or more heat exchanger plates or on combinations of one or more flow module plates, one or more reactor plates, or on one or more heat exchanger plates, which plates are placed between the two end plates. 2. The clamping device according to claim 1, wherein the wherein each piston of the grid of pistons is moveable independent of each other. 3. The clamping device according to claim 1, wherein the tension rods are arranged along the periphery of the end plates, the tension rods having at least one of fixed length, modular length to set several predefined fixed lengths, the fixed length is at least defining a thickness of one plate, and the fixed length defining total thickness of several plates. 4. The clamping device according to claim 1, wherein the tension rods are at least one of motor driven mechanic jacks, or motor driven roller screws, tension rods tensioned by hydraulic actuators. 5. The clamping device according to claim 1, wherein each piston is locked on an opposite side of the end plate with a washer and a retaining ring. 6. The clamping device according to claim 1, wherein screws are screwing together the tension rods with the two end plates having the grid of springs and the flow module plates, or the reactor plates, or the heat exchanger plates, or combinations thereof arranged between the two end plates. 7. The clamping device according to claim 1, wherein the tensions rods are configured in a first row of tension rods having at least two of the tension rods therein and a second row of tension rods having at least two of the tension rods therein; and the grid of springs being positioned between the first row of tension rods and the second row of tension rods. 8. The clamping device according to claim 1, wherein the tensions rods are configured in a first row of tension rods having at least two of the tension rods therein and a second row of tension rods having at least two of the tension rods therein; and the grid of pistons being positioned between the first row of tension rods and the second row of tension rods. 9. The clamping device according to claim 1, wherein each of the tension rods extends through a respective hole in at least one of the two end plates. 10. The clamping device according to claim 1, wherein each of the pistons extends through a respective hole one of the two end plates. 11. The clamping device according to claim 1, wherein the each of the pistons extends through a respective hole in one of the two the end plates and is locked on an outwardly facing side of the end plate with a washer and a retaining ring; the washer and the retaining ring are positioned on a portion of the piston that extends through the hole to the outwardly facing side of the end plate; andthe washer and the retaining ring are located outwardly from the outwardly facing side of the end plate.
