Helium Charge Recovery 4.5MPa Nitrogen Gross Leak Detection Equipment 8 min / pc

Helium Charge and Recovery System with Nitrogen Gross Leak Detection System

The system is used for helium charge recovery and leak detection of air conditioning systems. Firstly, a large leak tightness test is performed on the workpiece to be inspected by using a nitrogen pressure of 4.5 MPa, then 2.0MPa helium is charged into workpiece, and then helium mass spectrometer with sniffer gun is applied to the workpiece for fine leak detection, after that helium inside of workpiece is recovered. The system can determine the qualified and unqualified workpiece, and the leak point of the unqualified product.

Basic Technical Indicators

Workpiece	Assembled refrigeration system
Maximum internal volume of workpiece	100L
Gas for gross leak detect	High pressure nitrogen
Gas pressure of gross leak detect	4.5MPa (downward adjustable)
Helium pressure of leakage	2.0 MPa (downward adjustable)
Connector	2 sets of 1/4" standard quick female connectors 中间的适配器,它可以适应to the 1/4" needle valve interface of the workpiece,1 ½ threaded interface and 1 ¼threaded interface.
Test cycle	8 min/pc
Other	The equipment can be connected with the filling and discharging device on the customer's site, the discharge pipeline is connected with the recovery pipeline of the equipment, and the charging pipeline is connected with the charging pipeline of the equipment; the filling process of the two equipment can be carried out at the same time, but recycling process can only processed for one workpiece at a time, the another workpiece will be recycled automatically then.
Helium recovery rate	≥98%
Equipment size	2.0*1.5*1.8m
Equipment noise	≤70 decibels (with silencer in the exhaust process)

Advantages:

The equipment adopts 55bar high-pressure helium gas storage to reduce the volume of the helium gas tank. The high-pressure tank is installed inside the equipment, which makes the equipment compact and has a small footprint.

In order to protect the customer's clean inspection workshop from helium pollution, all joints of the equipment are subjected to a leak detection process to ensure that the entire equipment will not leak.

Equipped with computer and scan code gun, the internal program is associated with production system of production line.

采用INFICON P3000检漏仪,le最高ak detection rate is 1.0E-8Pa.m3/sec.

The system is controlled by PLC, operated on touch screen.
