Sight Glass

HVAC &

Refrigerant Tools

                  Sight glasses are mostly installed in the liquid line between the filter drier and the expansion valve to monitor the condition of the refrigerant. The SGR is mainly used to indicate the condition of the refrigerant as well as the liquid level in the receiver or the oil level in the compressor and has no moisture indicator. The SGI and SGRI are equipped with sensitive indicators that reflects a colour, depending on the moisture content in the refrigerant.

​

Applications

  • Traditional refrigeration

  • Heat pump systems

  • Air conditioning units

  • Liquid coolers

  • Transport refrigeration

​

Facts

  • Designed for CFC and HCFC refrigerants.

  • Flare-/solder connection or socket type.

  • Wide range with sizes from 6 to 22 mm.

  • Max. working pressure: 35 bar.

  • Working temperature: –50 to 80°C.

  • Approvals: PED, UL, GOST.

Advantages

  • Best visual indication of moisture (minimal dependence on temperature).

  • The flare ext. × int. version can be screwed together with filter drier (reduction of assembly costs).

  • Flare connections are 4-sided for quick installation.

  • Extended solder connections.

  • Glass diameter permits high working pressures.

1) Code numbers in bold are normally on stock and a shorter delivery time can, therefore, be expected.
2) Can be mounted directly into the filter drier.
3) ISO 228/1.
