Water-Cooled Thermochillers

The TGR Series is a water-cooled combination chiller with an optional heater. Available in multiple configurations including single and dual temperature zone. With integrated free-cooling and customizable P4 or P6 pumps, it is a great option for a variety of processes. The 3-way mixing valve allows the unit to intercept and mix heat transfer fluids from the heating and cooling system to either mix or divert the flow and best control temperatures. Each unit uses environmentally friendly R513A refrigerant and are engineered with integrated free-cooling to achieve the maximum energy savings.

→ RS485 MODBUS RTU protocol communication
→ Remote Start / Stop – Remote General alarm

REFRIGERANT CIRCUIT

The activity of the TGR thermo-chiller is based on a vapor compression cycle implemented in the chiller circuit and made up of these components:

    • Evaporator
    • Compressor
    • Condenser
    • Electronic Expansion Valve
    • Electronic Hot Gas Bypass Valve

The TGR Series can also work in free cooling mode when the return water temperature from the central cooling system (condensation side) is cold enough to satisfy the user water setpoint and it consequently allows to switch off the refrigerating compressor for energy savings.
