Direct-fired EcoChill Nxt chillers and heaters are available from 75 to 1,150 USRT, achieving chilled water temperature down to 38.3°F (3.5°C). Series flow of weak solution through the heat exchangers of vapor absorption machine ensures that maximum absorbent concentration and maximum temperature do not occur simultaneously in the generators, reducing likelihood of corrosion. Features include choice of modulating-type or staged burner; a crystallization temperature at least 18°F below operating temperature; thermally efficient cycle; multi-fuel capability; gravity feed system; PLC-based control panel; and corrosion inhibitors.
