SGC-4000HG: Stirling Gas Cooler

SGC-4000HG: Stirling Gas Cooler

The Apex Instruments SGC-4000HG Stirling Gas Cooler is specially designed for removing moisture and acid gases from flue gas samples. This new gas cooler uses an industrial grade super efficient Free Piston Stirling Cooler (FPSC) for chilling the sample gas to remove moisture. The Stirling will provide a robust, closed, dual channel gas conditioning system to deliver dry, acid free gas to the meter console No peristaltic pumps to leak.

All applicable components are rated 120V/60Hz or 240V/50Hz.

SKU: SGC-4000HG Category:




  • FPSC Chiller Module uses Environmentally Safe Helium Gas as a Refrigerant, no CFC’s.
  • The Module is Hermetically Sealed in Stainless Steel Casing for Fast and Easy Installation or Replacement as Necessary.
  • The Cold end of the FPSC is Inserted Directly into a Machined Anodized Aluminum Chiller Block.
  • C276 Hastelloy Serves as the Reverse Flow Condensate Separators.
  • Six Times Efficiency of Thermoelectric (peltier) Coolers.
  • Uses Less than 40w of Electricity.
  • 12 V DC Power Supply.

Features of the FPSC Stirling technology:SGC-4000HG Page Visual

  • Stirling thermodynamic cooling uses inert helium instead of refrigerants making them safer than tradition cooling technology
  • Constant set temperature
  • Integrated heater
  • Free Piston Stirling Cooler (FPSC) technology has  only two moving parts reducing the risk of failure
