DESCRIPTION
The Series TEC1 Peltier Gas Sample Cooler is supplied complete with a Jet-Stream heat exchanger made
either of Duran glass, stainless steel, PVDF or Hastelloy.
The exchanger is housed for ease of replacement in a thermally insulated cooling block on the sides of the
cooler. The temperature is measured with a Type K thermocouple sensor and regulated electronically by
Peltier elements to a constant temperature of +4°C.
The system ensures optimum cooling of the sample gas and condensate separation.
The heat energy emitted by the cooling system is dissipated via a generously sized cooling fin block with
forced ventilation.
The electronic control system with display and the power supply unit are housed in a protective stainless steel
enclosure on the front of the heat sink.
An over and under temperature alarm as a status group alarm is available for external indication, via a dry
contact closure. The alarm thresholds default to 4°C above and below the control temperature and can be
adjusted in the menu via the keypad.
The gas inlet and outlet is located on the top of the cooler and is indicated by arrows on the Jet-Stream heat
exchangers. On standard models with Duran glass heat exchangers, the gas connections are provided with
GL18-6 mm PTFE sealing rings and on stainless steel, Hastelloy or PVDF exchangers with 1/4" NPT female
threads.
The condensate drain of the Jet-Stream heat exchangers are located beneath the cooler and have GL25-12
mm PTFE sealing rings as standard on the Duran glass heat exchangers. The stainless steel, Hastelloy or
PVDF exchangers are supplied with 3/8" NPT.
The type of condensate discharge used will depend on the type of operation:
•
Peristaltic Pump:
o
Integrated onto the chiller itself for automatic condensate discharge in vacuum and pressurized
operations.
o
External Type PP for automatic condensate discharge in vacuum and pressurized operations.
•
Automatic Float Condensate Discharge Type AD-
…
for pressurized operation only.
•
Condensate Collection Vessel Type TG.../TK... with manual drain for either pressurized or vacuum
operation.
O
ption: Liquid alarm sensor LA…
For protection against liquid breakthrough and to increase the dependability of the complete system we
recommend the use of a liquid or condensate alarm sensor Type
LA1S . The sensor should be mounted
externally into the sample line between the cooler and the analyzer.
