The indicatoros series 32200 allow safe and immediate control of the degree of humidity and the liquid state of the refrigerant thanks to the color change of the sensitive paper placed in the center of the specific viewer. The indicated humidity values are to be considered acceptable according to the type of refrigerant fluid used, as indicated in the table below. The 32200 series differs from the 32000 series because it can be assembled in total safety, without incurring the risk of welding which could damage the internal seals.
  • LOW COST
  • SOLID 
  • SAFE
  • LOW COST FULL SEALING
  • CAPACITY
  • EASY AND SAFE The part with indicator disk can be interchangeable
  • Neoprene sealing O-ring (HNBR option)
  • Rolling of the sight glass without introducing stressing elements in the material that could generate cracks
  • Stress-relieving of the body after machining
  • Problems about indicator overheating are eliminated: the welding is made when the indicator is disassembled from the body.
  • 100% TESTED, each valve bears the date and serial number proving that it has passed the test and allowing traceability of the performance data measured during testing over tim
The liquid and humidity indicators are designed to be installed on refrigeration and air-conditioning systems for domestic and industrial use. It’s possible to use them with all the refrigerant fluids of group II (as defined in Article 13, chapter 1, Point b of Directive 2014/68/EU, with reference to EC Regulation No.1272/2008) and they are defined as “pressure equipments”, as described in Directive 2014/68/UE, Art.2, point 5, Art.4 point 1.C.
  • The main construction components of the indicators of the 32200 series are:
  • Moisture and saddle body made of brass ST-UNI EN12165-CW617N
  • TN-UNI EN12164-CW614N brass indicator
  • Inspection glass
  • PTFE sealing gasket of the glass
  • Test paper for humidity (for model with -0 final code) 
  • Double sealing O-ring made of Neoprene (HNBR option for flammable fluids)
At the start-up of circuit the color of test paper can be yellow, in consequence of atmosferic humidity or humidity contamination of plant where the indicator is installed. When the humidity level of refrigerant fluid is steady, by the action of dryer filter, the color of test paper becomes green, because the equilibrium conditions are reached. Normally, the time required to reach the stationary condition of circuit is 12 hour; if the yellow color of test paper remains, it means that is necessary a further action to eliminate the humidity presence inside the circuit. The braze welding of indicators equipped by copper tubes should made by special alloy, with low melting point. The flame should not be directed toward the glass or body of indicator, because it can damage the indicator in consequence of overheating.
