Why use ATEX tools with R290?

R290 (propane) has become one of the most widely used natural refrigerants in the HVAC-R industry. Efficient, environmentally friendly, and compliant with F-Gas regulations, it also presents a major risk: its flammability. To ensure technician safety and comply with current standards, the use of ATEX-certified tools is essential. In this article, we explain why and how to work safely with R290, and which specific equipment is available from LINSTRUMENT.

R290: a high-performance but flammable refrigerant

R290 belongs to the family of hydrocarbons (A3 class). It is valued for its very low environmental impact (GWP = 3) and excellent thermodynamic performance. However, its high flammability requires strict safety measures:

• Explosion risk in case of leakage and accumulation in poorly ventilated areas
• Obligation to comply with ATEX safety standards (explosive atmospheres)
• Necessity of using tools specifically designed to prevent sparks or ignition sources

Which ATEX tools are needed for working with R290?

When servicing systems charged with R290, it is essential to be equipped with a complete set of ATEX-certified tools covering every stage of the intervention. Below are the main categories of equipment, with references available from LINSTRUMENT.

•  Ventilation and Air Renewal
  An ATEX fan ensures safe evacuation of propane vapors, preventing gas accumulation.
  ➡ BLW-250-EX – 25 m³/min airflow, robust steel frame, certified Ex db IIB T4 Gb.

• Gas Detection and Monitoring
  An ATEX explosimeter continuously monitors gas concentration and alerts the technician when critical thresholds are reached.
  ➡ YT-1200H-S-R290 – clear %LEL display, configurable alarms.

• Flammable Refrigerant Recovery
  Recovering R290 requires a reliable, spark-proof ATEX recovery station.
  ➡ TREK-POWER-EX – brushless 1.3 HP station, certified ATEX Ex II 3G.

• Brazing and Nitrogen Inerting
  An ATEX pressure regulator ensures safe brazing and inerting during work on systems charged with A3 refrigerants.
  ➡ PRG-125 – manual regulator/flowmeter (0–30 L/min), stainless steel build, compact, supplied in carrying case, European-made with French quality control.

• Pressure Measurement and Control
  A manifold compatible with R290 must be both robust and precise.
  ➡ MG-470-PAC – 4-way analog manifold with oil-filled gauges, supplied with adapted hoses.

• Secure Hoses and Accessories
  Zero-emission hoses reduce refrigerant releases and protect technicians during interventions.
  ➡ VZE Hoses – pivoting design, zero-emission valve, dual nitrile O-rings.

Conclusion

R290 offers many advantages in terms of performance and environmental impact, but its flammability requires absolute vigilance. Following strict safety procedures and relying exclusively on ATEX-certified tools is not optional—it is a necessity. The ATEX range offered by LINSTRUMENT—fans, explosimeters, recovery stations, nitrogen regulators, manifolds, and hoses—provides a complete and reliable solution for working safely with A3 refrigerants such as R290. By choosing ATEX-certified equipment, you protect your teams, ensure regulatory compliance, and guarantee safe and professional interventions.
