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
Mai Fathi Gabr
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

CAREL is characterized mainly operates in control and it is manufacturing a complete range of Isothermal and Adiabatic air humidification systems , It was established in 1973

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
Mai Fathi Gabr
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.
