AIRTECT is an Irish company specialising in the development and manufacture of molten plastic leak detection systems for injection moulding machines and hot runner moulds.
With over 15 years of experience in this field, AIRTECT focuses on preventing damage, unplanned downtime and high repair costs caused by leaks at the injection moulding machine nozzle or within the hot runner system.
AIRTECT products are designed and manufactured in Ireland and are used by companies worldwide, including those in the automotive, medical and packaging industries.

How Does AIRTECT Work?
The systems use small amounts of low-pressure air flowing through sensor tubes made of stainless steel and silicone rubber.
In the event of a plastic leak, the airflow is restricted or interrupted. The system detects this change and generates a signal that can be used to trigger an alarm or automatically stop the machine before serious damage occurs.
AIRTECT offers solutions for both machine nozzle protection and multi-zone monitoring of hot runner systems and injection moulds.
Key Benefits
- Early leak detection;
- Protection of the mould, hot runner system and machine;
- Automatic setup – auto-tuning;

- Reduced unplanned downtime;
- Lower repair costs and production losses.
The KRASCO-CO team will assist our customers in selecting the most suitable AIRTECT system based on the specific injection moulding machine, mould, number of monitoring zones and production process.
Our goal is to provide the right solution for the early detection of plastic leaks, reducing the risk of damage and minimising unplanned production downtime.
