Package Water-Cooled Process Chillers with Integrated Stainless Tank

Legacy’s model PZWT water-cooled chiller system is ideal for smaller lab environment cooling applications. Available in 1.0 to 20.0 HP. 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.

The Legacy Chillers PZAT process chiller line is ideal for the following applications:

– Brewery
– Winery
– Distillery
– MRI – Medical Imaging
– CT – Medical Imaging
– PET – Medical Imaging
– Linac – Cancer treatment
– Surgical Center climate control
– Lab applications
– Semiconductor testing
– Induced hypothermia systems
– Lasers – military sector
– Laser – private sector
– Custom batch cooling
– Welding machines
– Lasers – military sector
