Introducing the Air Chiller System
Overview
Air Chiller
The ACS is a unique multi-stage Air Chiller System for sub-ambient temperature control and general cool-
ing of the DMA 850 with the standard furnace. The ACS units feature CFC-free durable compressors,
small footprint, and uninterrupted operation for specified temperature ranges–eliminating the recurring
cost and safety concerns associated with handling and use of liquid nitrogen. The Air Chiller Systems
require an air supply at pressure of 6.9 bar (100 psi), flow rate of 200 SLPM (Standard Liters Per Minute),
and pressure dew point of at least -40°C (-40°F) or better, and appropriate instrument-specific Chiller
Panel. Note that the dew point is to be measured at 6.9 bar.
