EXTERNAL BY-PASS valve helps draining pressure peaks generated by sudden increase of oil viscosity and/or flow rate.
THERMOSTATIC VALVE ensures a fast oil temperature warming up in particular harsh climate, with very cold oils.
OMT provides the possibility to integrate by-pass and, if required, the thermostatic valve in one compact and economic solution.
During the start-up process, cold oil goes around the heat exchanger by-passing the core and preventing it from any possible damage.
As the oil reaches 40°C temperature, thermostatic valve begins to close proportionally until it reaches its complete shutdown at 55°C, avoiding thermal shocks.
In the event that, due to sudden flow increases or physical decreases of the sections of the pipes, pressure overtakes the preset value of the by-pass valve, thermostatic valve opens protecting the core.
BY-PASS VALVE eliminates the pressure drops problem when the oil viscosity is higher and ensures better temperature control, making the cooler more performing.
