Low Temperature & Ammonia
Overview
Teqtive ammonia chillers use R-717, a natural refrigerant with zero ozone depletion and zero global warming potential, for large industrial refrigeration plants from 20 TR up to 1000 TR.
Plants are built with open screw or reciprocating compressors and a choice of shell-and-tube, semi-welded plate, ice bank tank (IBT) or falling-film pillow-plate evaporators, covering 0 °C to −40 °C.
