Fluid flow and pressure
KT chillers fitted with a 2 or 3 litre per minute pump are capable of producing up to 150
psi, because of the high pressure volumetric pump. These units are normally supplied
factory set to run at an operating pressure of 35 psi, which is suitable for most applications.
The pressure setting is controlled by an internal bypass valve, which will open above the
preset level to protect your application from higher pressures.
It is possible for customers to change the operating pressure of all K series chillers, except
KT chillers fitted with a 6 litre/minute pump
