◆Triple distribution box------------------------------- ------------------ --------------- ----- --------- ----------- -------- Fig.1
◆Multi-function meter-------------------------------------------------- ------------------ --- ------ - -------- ------------- Fig.2
◆Control valvle-------------------------------------------------- ----------------------------------------- ---- -- ---------- - Fig.3
It can avoid refrigerant overflow when moving the refrigerant, it can make the liquid tube and liquid filling
port opening are closing in an instant.
◆Filling safty equipment (Gas Liquid Seperator) ---------------------------------------------------- ------ ---------- --Fig.4
In general, the refrigentrant must be converted to liquid, because refrigerant R410A is a mixed system,
if the combined ratio changes there will be a certain risk. In order to avoid the refrigerant return to
compressor in liquid, you can use this device to make refrigerant safely entering the compressor.
◆Eletronic balance---------------------------------------------------------- ---------------------------------- -------------- Fig.5
The recommended equipment for filling R410A
◆Refrigerant storage tank----------------------------------------------- ------------------------------- ---------------- ---- Fig.6
It must confirm the type of refrigerant before filling, liquid refrigerant is filled usually.
◆Thermistor vacuum gauge-------------------------------------------- ---------------------------------- -------------- --- Fig.7
In ordet to completely remove Refrigerant vapor, take appropriate vacuum is necessary. You can use
this device to determine whether the system is a vacuum environment.
◆Vacuum pump----------------------------------------------------------------- ------------------------------- -------------- Fig.8
◆Welding tools---------------------------------------------------------------- --- ------------------------------- ------------Fig.9
◆Tube bender-------------------------------------------------------------------- ---- ----------------------------- --------- Fig.10
◆Tube expander-------------------------------------------------------------------- --- ------------------- ----- --- --------Fig.11
In order to adapt to high pressure characteristics of R410A, the shape of the tube expander is different from
the conventional expander
