BITZER shell and tube evaporators support high-, medium-, and low-temperature applications down to −40°C. Direct expansion evaporators with U-tube or single-pass design deliver low-approach temperature differences, while hybrid and flooded evaporators provide high efficiency. Different series are available with various materials, approvals, and capacities for HFC, HFO, NH₃, and hydrocarbon applications.

• Direct expansion evaporators: series SQD, DH, PureCooler, DM with capacity up to 2 000 kW
• Hybrid and flooded evaporators: series FEV, RFV with capacity up to 5 000 kW
