Leak Detection Systems

We offer three types of leak detection systems for the refrigeration industry:

Atmosphere – Tracer Gases
Atmosphere – Refrigerants
Vacuum Chamber

Atmosphere – Tracer Gases

Atmosphere – Refrigerants

Vacuum Chamber

ProbHe

ProbHe has been designed and built to be used in any kind of assembly lines of cooling units (refrigerators, deep freezers, air conditioners etc…) performing evacuation, pressurization with nitrogen for mechanical and gross leak test and pressurization by tracer gas (helium/hydrogen mix) for fine leaks. Furthermore ProbHe can perform volume, flow and humidity measurements as well as flushing tests with nitrogen. The working phases for each cycle are fully programmable. In order to guarantee maximum quality and performance the system can be interfaced with the Herec K helium recovery system.

ProbHe M (Multisniffer) features a manifold that connects up to 8 custom sniffing pliers (instead of using the leak detector sniffer probe). The manifold can be combined with the most common leak detectors in the market. Each plier has a specific led indicator that guarantees easier and faster readings. The main goal of the Multisniffer version is to reduce the human error in the leak detection, and it is particularly suited for high production rate lines.

Model	Max working pressure	Fluid inlet lines	Number of fillers
ProbHe/M	45 bar	2+2*	2
ProbHe HP/M	140 bar	4	2

*optional

Kairos

Engineered and built to be used in any kind of small/medium assembly lines (refrigerators, deep freezers, air conditioners, etc.), Kairos performs evacuation, pressurization with nitrogen for mechanical stress tests and gross leak tests and pressurization by tracer gas (helium/hydrogen mix) for fine leaks and final discharge. In order to guarantee the maximum quality and performance the system is interfaced with the Herec K helium recovery system.

Model	Max working pressure	Fluid inlet lines	Number of fillers
Kairos	Up to 30 bar (40 bar*)	2	1+1*

*optional

Kairos Rec

Kairos Rec has been designed and built to be used in any kind of high production assembly line (refrigerators, deep freezers, air conditioners, etc.) performing the recovery of tracer gas used in previous stations up to 30 bar (ProbHe).

It is possible to connect the leak detector and do the “sniffing” of the piece under test already charged with a tracer gas (Helium). Kairos Rec can record the leak value read by the leak detector.

In order to guarantee the maximum quality and performance the system can be interfaced with the Herec K helium recovery system and can be provided with or without vacuum pump.

Kairos DT

Engineered and built to be used in any kind assembly lines of cooling unit (refrigerators, deep freezers, air conditioners, etc.) and hydronic unit.

Kairos DT performs pressurization with nitrogen for mechanical stress tests and pressure decay test up to 30 bar.

The pressure decay test can guarantee leak detection between 10^-2 mbarl/s and 10^-4 mbarl depending on the unit and on the cycle configuration.

It is particurarly indicated for testing of hydronic units and on cooling circuits as pre filtering station for detecting gross leaks or as substitute of water bubble test.

All the above listed Leak Detection Machines are completely integrated with GEDA system for data acquisition and statistics, remote programming as well as external supervision of the line.

Multiref

Multiref has been built for any type of cooling unit assembly lines (refrigerators, deep freezers, air conditioners, etc.) and it performs leak detection on refrigerant precharged units. The automatic leak detection is carried out by using the patented Galielo tp Multisniffer technology that guarantees objective readings of the leaks as well as traceability.

The systems features a manifold that connects up to 8 custom sniffing pliers (instead of using the sniffer probe of the leak detector). The manifold can be interfaced with the most common leak detectors in the market. Each plier has a specific led indicator that guarantees easier and faster usage.

The main goal of the machine is to reduce the human error in the leak detection process, and it is particularly suited for high production rate lines.

Multiref is completely integrated with the GEDA system for data acquisition and statistics, remote programming as well as external supervision of the line.

Helisystem

Helisystem is a measuring equipment of Galileo TP Process Equipment developed for highly sensitive leak detection with helium in vacuum chambers.

The equipment performs an integral helium leak test at various pressures. It verifies the perfect tightness of the device under test by using the technique of the global test under vacuum chamber. Helisystem is industrial equipment engineered according to customer needs, however, thanks to a dedicated industrialization and standardization process, it provides reliability, accuracy, efficiency and easy maintenance. In order to guarantee maximum quality and performance the system is interfaced with the Herec K helium recovery system.

Thanks to our long time experience and advanced know-how we tailor the best solutions for the customer’s needs.
