 Description

The T701 adds Modbus TCP/IP connectivity to the proven reliability and performance of our zero air systems.  This allows remote monitoring of key instrument functions including dewpoint status, scrubber temperature, box temperature, and output pressure.  Additionally, this digital access provides the ability to remotely disable the internal pump, allowing longer service intervals and less power consumption.  The user can also remotely start instrument warm-up prior to arrival at the site.

The T701 is a fully self-contained source of clean, dry air for dilution calibrators. It can also be used to create purge air for permeation tube ovens or burner air for FID analyzers.  The T701 includes a dewpoint sensor, an oil and diaphragm-free pump, and scrubbers to remove SO2, NO, NO2, O3, H2S, and NH3.  Optional high performance scrubbers are available to remove CO and Hydrocarbons.

The regenerative, heatless dryer removes water and produces output with a dewpoint of less than -20°C (up to 15 SLPM flow rate).  The system's pressure, temperature, and dew point values are all continuously monitored, which allows a microcontroller to adjust the pump cycling frequency, valve timing, and heater power for optimal performance. ​
