GX-K1 Refrigerant Leak Detector

GX-K1 Refrigerant Gas Alarm: Plug-in Early Warning System for Heat Pumps and Air Conditioners

A small leak – and harmful, flammable, or climate-damaging refrigerant escapes. The GX-K1 from Elektrotechnik Schabus GmbH & Co. KG stops this danger before it starts: simply plug it in, wait 3 minutes, and you’re protected. 

The high-performance internal sensor detects fluorinated refrigerants (HFC/HFO) such as R-22, R-32, R-404A, R-410A, R-407C, R-1234yf, R-1234ze, R-454B, and R-290 even at minimal concentrations – long before health or environmental thresholds are exceeded. 

When a leak is detected, the red LED flashes and a piercing piezo buzzer sounds – ensuring immediate action. No installation, no electrician, just plug-and-play safety for private and commercial systems. Made in Germany and supplied with instructions, the GX-K1 is your invisible guardian in technical rooms, apartments, and offices – because leaks don’t wait.

The GX-K1 technology is based on a sensitive semiconductor sensor with a high cross-sensitivity range. The resistance ratio Rs/Ro (reference: 5,000 ppm R-32) ensures precise and consistent measurements. The sensor responds not only to traditional HFCs but also to modern HFO blends and related gases such as methane, butane, ethanol, and hydrogen. 

After a 3-minute warm-up, the system is fully operational – alarm within seconds. Function test? Simply use a small amount of lighter gas – easy and safe. Powered via a 230 V socket – no batteries, no downtime. The GX-K1 is approved for use only in dry, non-explosive indoor environments. It supports EU F-Gas regulations through early leak detection – reducing refills, environmental impact, and maintenance costs. The GX-K1: prevention that works – before a leak becomes a disaster.

The GX-K1 is more than a detector – it’s active health and environmental protection. Whether for domestic heat pumps, office air conditioners, or commercial refrigeration units: a faulty valve, cracked line, or leaking compressor – the GX-K1 detects it early. Homeowners save on repair costs, facility managers meet compliance obligations, and technicians avoid downtime.

Its robust design, user-friendly operation, and German engineering make the GX-K1 a reliable long-term companion in refrigeration safety. It proves that protection can be as simple as plugging in a device. With the GX-K1, you invest in the future – a future of efficient systems, clear air, and reduced CO₂ footprint.

• Fast response: Alarm within seconds, operational after just 3 minutes warm-up time.
• Plug & Play: 230 V socket – no installation, instant protection.
• Loud alarm: Piezo buzzer + flashing red LED – impossible to miss.
• Easy testing: Verify function using lighter gas – simple and safe.
• Health & environmental protection: Early warning against toxic, flammable, and climate-harmful gases.
• Made in Germany: Top-quality craftsmanship, long service life (up to 5 years), and Schabus support.

Applications: Where the GX-K1 Is Essential

The GX-K1 ensures leak safety in numerous private and technical applications:

• Heat pumps (air-to-water, brine-to-water): Detects R-32, R-410A, R-454B – protects against performance loss.
• Split & multisplit air conditioners: Alerts for R-32 or R-1234yf leaks in homes, offices, or hotels.
• Refrigerated cabinets & freezers: Monitors R-404A, R-407C in supermarkets and restaurants.
• Technical & server rooms: Secures precision air conditioning – for 24/7 operation.
• Private homes: Retrofit protection for wall units or VRF systems.
• Commercial & industrial sites: Complements maintenance plans in production and logistics.
• Renovation & retrofits: Ideal for conversion to modern refrigerants – complies with F-Gas requirements.

With the GX-K1, protection starts at the power socket. It’s the simplest, fastest solution for anyone operating cooling or heating systems – without compromise on safety or sustainability. Its wide detection range, loud alarm, and German quality make it a must-have for all modern HVAC systems. 

Refrigerants leak silently. The GX-K1 warns loudly. Just plug it in. Stay safe. Take action now – before a leak becomes costly. Your early warning system begins here.

Scope of delivery

• Refrigerant gas alarm GX-K1 with internal sensor
• User manual

General Safety Instructions

• Before installation or operation, read the user manual carefully.
• Installation must be carried out by qualified personnel.
• Packaging materials are not toys. Keep them away from children.
• Do not open the device; it contains no user-serviceable parts.

Intended use

• The FKW ALARM GX-K1 / GX-K2 is a warning device for refrigerants in the FKW group, providing an alert long before concentrations reach hazardous levels. This monitoring system is therefore set to a very sensitive range for early detection. 
• The alarm is both acoustic and visual. The device is suitable for normal domestic use and must not be used in potentially explosive areas. 
• The detector warns against toxic fumes that may escape from leaking cooling systems or heat pumps, protecting people from inhaling them.
• Any use other than that described above is not permitted.
