Process Chillers
Overview
Teqtive air cooled screw chillers are built for large, continuous industrial loads. Economized semi-hermetic or open screw compressors give stable capacity control across the range, and the air cooled condenser removes the need for a cooling tower and its water treatment.
Units are available from 40 TR to 500 TR for chilled water and glycol from +25 °C to −10 °C, with PID, PLC or microprocessor control and DOL, star-delta, soft-starter or VFD starting.
