Is one of the first companies in the field of dynamic balancing valves in the world with Griswold States of American company , It Was established in 1945.

Dynamic Static Q = Kv √p

Deal with the change of pressure in the cycle with the change of area through the spring movement into Cartridge

Fixed amount of water in Δp

Does not deal with the change of pressure in the cycle With the stability of the area consequently be a variable flow rate Is not compatible with the idea of

balancing valve

Error rate Error rate We don’t need to test and balance and

commissionJust check

Need to test , balance and commission and need to adjust every valve 3 times to

have flow accuracy Just need at terminals units

no valve at (branches , riser , main line ) so it cost less valve ,installation time

Need at all terminals , units, branches , riser , pump

NO need to design install need to design install

Because Frese company specializing characterized in the dynamic balancing valve by its accuracy and its ongoing development

Pressure independent control valve (PICV) compined valve :

1- Thermostatic Modulating Control Valve Differential Pressure Control Valve Dynamic Balancing Valve2- Accurate Flow and Temperature Control3- Full Stroke Modulation 4- Control Valve authority

1- Isothermal steam humidifier: The cylinder is filled by means of an electro valve Galvanized steel electrodes immersed in water are powered Water acts as an electrical resistance depending on dissolved salts The electric current heats up the water Advantages : Antifoam sensor and display

2- Adiabatic Humifog multizone:a pistons pump to pressurize the water up to 70 bar; special

nozzles produce billions of very small droplets that spontaneously evaporate, humidifying and cooling the air.
