At Chillventa 2026, General Gas will present the GK-Lab range, a family of professional chemical additives designed to help installers and service technicians address key maintenance issues in refrigeration and air conditioning systems.
The range focuses on three specific solutions: KryonLeakGuard for refrigerant micro-leak repair, KryonAcid Stop for acid neutralisation and KryonDry Nova for residual moisture removal from refrigeration circuits.
Developed through research at General Gas laboratories, the GK-Lab range brings specialist chemical solutions to HVAC/R maintenance, with formulations designed to address specific issues while helping preserve system reliability, performance and component integrity.
Three maintenance challenges, three targeted solutions
General Gas will highlight three additives from its GK-Lab range at Chillventa, each formulated to address a specific issue within the refrigeration circuit.
KryonLeakGuard
A non-polymeric leak-sealing solution designed to repair small refrigerant leaks in refrigeration, air conditioning and automotive A/C systems.
KryonAcid Stop
An acid-neutralising additive developed to counteract acidic compounds in the circuit, helping protect metal components and the compressor.
KryonDry Nova
A moisture-removing additive designed to address residual water contamination and help prevent ice formation in expansion devices.
REFRIGERANT MICRO-LEAK REPAIR
GK-Lab KryonLeakGuard
KryonLeakGuard is a non-polymeric GK-Lab leak sealant developed to repair refrigerant micro-leaks in automotive air conditioning, refrigeration and HVAC systems.
The formulation circulates through the system with the refrigerant and compressor lubricant. At the point of leakage, it forms a stable, flexible seal to help restore circuit tightness.
Compatible with PAG, POE and mineral oils, the product features a polymer-free formulation designed to minimise the risk of clogging capillary tubes, expansion valves and refrigerant charging equipment.
ACID NEUTRALISATION
GK-Lab KryonAcid Stop
KryonAcid Stop is a high-performance acid-neutralising additive developed to counteract acidity within refrigeration and air conditioning circuits.
Its formulation acts on acidic compounds that may form as a result of lubricant degradation or moisture ingress, helping prevent corrosion of metal components and potential compressor damage.
Compatible with PAG, POE and mineral oils, it can also be used following compressor replacement and as part of preventive maintenance procedures.
MOISTURE CONTROL
GK-Lab KryonDry Nova
KryonDry Nova is a GK-Lab moisture-removing additive formulated to address residual moisture in refrigeration and air conditioning circuits.
The formulation binds to water molecules, converting residual moisture into a stable solution that circulates with the lubricant without altering its viscosity characteristics.
Controlling residual moisture helps prevent ice formation in expansion valves and capillary tubes. The product is suitable for use with PAG, POE and mineral oils.
Comparing the three GK-Lab additives
| Feature | KryonLeakGuard | KryonAcid Stop | KryonDry Nova |
|---|---|---|---|
| Main function | Repairs refrigerant micro-leaks | Neutralises acidity | Removes residual moisture |
| How it works | Forms a flexible seal at the leak point | Acts on acidic compounds within the circuit | Binds water molecules into a stable solution |
| Typical use | Small refrigerant leaks | Acid contamination or maintenance following compressor replacement | Residual moisture contamination in the circuit |
| Compatible lubricants | PAG, POE and mineral oils | PAG, POE and mineral oils | PAG, POE and mineral oils |
Precise, professional additive injection with GK-Gun
General Gas has developed dedicated injection equipment to introduce GK-Lab additives into refrigeration and air conditioning circuits in a controlled and accurate manner.
The professional GK-Gun SMART injection gun is designed for 8 ml cartridges, while the GK-Gun PRO accommodates 48 ml cartridges. Both can be used with dedicated fittings for HVAC/R and automotive A/C systems.
Complete HVACR SMART, HVACR PRO and AUTO SMART kits are also available, providing technicians with ready-to-use solutions for different maintenance applications.
Product formats for different maintenance requirements
GK-Lab additives are available in different packaging and dispensing formats to suit technicians' working requirements and the specific characteristics of each system.
