Moisture Liquid Indicators ensure failsafe inspection of the conditions of the refrigerant fluid in the system as regards to the regular flow and moisture.
Liquid indicators also ensure inspection of the regular flow of oil feed-back to the compressor sump.
Before start up the moisture indicators colour may show colour as per the wet colour. This may be due to exposure to air and humidity and moisture in the circuit.
When the moisture of the refrigerant fluid is brought back to acceptable levels with the dehydrator, the indicator colour will show the approprite colour correspondling to dry.
Castle liquid indicators are manufactured with imported glass which has been directly fused onto the metal nut. This construction allow the total elimination of sealing gaskets between the glass disc and the metal structure with the consequent elemination of possible refrigerants.
The materials used for the main parts are:
- Bs- 218 forged brass for the flare brass indicators.
- Refrigeration grade copper tube for copper end indicators.
- Neoprene rings for sealing.
