Package Water-Cooled Process Chiller – Standard / Tankless

Legacy’s  PZW Water-Cooled Scroll Process Chiller Product Line is ideal for industrial cooling and refrigeration applications. Available in 1.0 to 60.0 HP. Cooling tower or other water source is required to cool the chiller condenser coil. STANDARD ON ALL LEGACY MODELS: Pentra Microsmart, Programmable Logic Controller (PLC) with HMI Touch Screen Display.

Keep in mind that ALL water-cooled condenser process chillers require a way to reject their heat normally to another water source such as a cooling tower.

Package Water-Cooled Process Chiller Tankless

The Legacy Chiller Systems PZW tankless process chiller line is ideal for the following applications:

– Cooling customer fluid storage tanks
– Lab applications
– Induced hypothermia systems
– Lasers – military sector
