WÜRTH - Spray congelante
19,25 €*
Uso universal para trabajos de reparación, montaje y diagnóstico.
Para la refrigeración dirigida de transistores, resistencias y componentes mecánicos y eléctricos. Ideal para la detección de fallos en circuitos electrónicos mediante la generación de estrés térmico controlado. Apto para su uso en el sector de la automoción, por ejemplo en carburadores y sistemas de inyección, para comprobar el funcionamiento de los dispositivos de arranque en frío. Previene daños por calor en el entorno de trabajos de soldadura mediante una refrigeración local precisa. En el rango de baja tensión conforme a VDE 0100 (rango de tensión: < 50 V AC, < 120 V DC), el spray también puede utilizarse bajo tensión.
El spray genera un potente efecto de enfriamiento de hasta –50 °C, lo que permite insertar fácilmente rodamientos de bolas, casquillos, ejes y componentes similares en ajustes muy estrechos. Además, el producto es adecuado para la prueba funcional de termostatos bimetálicos o de tubo capilar, utilizados con frecuencia como termostatos de protección contra heladas en intercambiadores de calor en sistemas de ventilación y climatización.

F-Gas Phase-Out, Reuse/Recycling & Replacement Summary
Brief technical summary of key EU F-Gas milestones, reuse/recycling considerations under maintenance contracts, and natural/low-GWP refrigerant replacements (R-290, R-32, CO₂).
Key phase-out milestones (EU — indicative)
| Date / From | Measure (summary) |
|---|---|
| 11 Mar 2024 | New F-Gas Regulation enters into force (framework for subsequent bans & quotas). |
| 2025 → | Restrictions on use of virgin (new) very high-GWP gases (GWP ≥ ~2,500). Recycled/reclaimed gases allowed in limited cases. |
| 2026 → | Extended service/maintenance bans for specific equipment categories unless reclaimed/recycled gas is used. |
| 2030–2035 | Stricter GWP ceilings by equipment type (stationary refrigeration, split A/C, heat pumps); progressive replacement required. |
| By 2050 |
Targeted near-complete phase-out of HFC consumption in the EU (long-term objective). |
Reuse & recycling — operational implications
- Recovery mandatory: refrigerants removed during service, repair or decommissioning must be properly recovered and documented.
- Reclaimed vs virgin: where regulation prohibits virgin high-GWP gases, only reclaimed/recycled gas meeting purity standards may be used (and only for defined categories & time windows).
- Traceability: maintain certificates of recovery/reclamation and purity reports in the maintenance file — contractual requirement for reuse.
- End-of-service: systems that cannot be economically converted to low-GWP refrigerants should be planned for phased replacement with approved alternatives.
Natural / low-GWP replacements (concise)
| Refrigerant | GWP & key property | Typical replacement use |
|---|---|---|
| R-290 (Propane) | GWP ≈ 3 — very low; flammable (A3). | Small refrigeration, plug-in units, some chillers where safety zones & charge limits permit; replacement for R404A/R507A in many small systems. |
| R-32 (Difluoromethane) | GWP ≈ 675 — lower than R410A; mildly flammable (A2L). | Split A/C and heat pumps — common retrofit / new-build replacement for R410A systems (with design & safety adaptation). |
| CO₂ (R-744) | GWP = 1 — non-flammable; very high operating pressures. | Supermarkets, industrial refrigeration, cascade systems, transcritical applications — replaces R404A/R134a in centralised solutions. |
Recommended maintenance contract clauses (core items)
- Mandatory recovery & documentation: all refrigerant removed must be recovered, labelled and accompanied by recovery/reclamation certificates stored for X years.
- Leak detection & repair SLA: defined maximum response time & leak repair performance targets (e.g., repair within 48–72 hours of detection).
- Approved reuse policy: specify when reclaimed gas may be reused (purity thresholds, lab certificate requirement) and when replacement with low-GWP alternatives is mandatory.
- Retrofit & replacement plan: technical and commercial plan for phased retrofit to approved low-GWP refrigerants; cost sharing and timeline milestones.
- Compliance audit: periodic audit right for the client to verify recovery, documentation, and regulatory compliance.
- Safety & training: contractor guarantees technicians are certified for handling flammable (A2L/A3) refrigerants and high-pressure CO₂ systems.
Note: The dates above summarise regulatory direction and are indicative. Local implementation, exact GWP thresholds and national enforcement may vary — include a clause requiring the contractor to remain compliant with the latest regional/national F-Gas rules.
