Description
Overview
SEASON Refrigerant Gas R-141b is a versatile HCFC-based solvent widely used for flushing and cleaning air-conditioning and refrigeration systems. Known for its strong solvency power and stable chemical behavior, R-141b effectively removes dust, carbon deposits, moisture, acid, and residual oil from refrigeration pipelines, ensuring smooth system performance and improved efficiency.
Apart from HVAC cleaning applications, SEASON R-141b is also used as a highly efficient blowing agent in insulation foam manufacturing due to its excellent expansion properties and thermal insulation performance.
Key Features
- Powerful Flushing Solvent: Removes oil, sludge, dirt, and moisture from A/C & refrigeration lines.
- High Solvency Power: Dissolves contaminants that other solvents cannot remove.
- Stable Chemical Composition: Ensures consistent and reliable performance.
- Dual Use: Also used as a blowing agent in PU foam and insulation manufacturing.
- High Purity: ≥ 99.5% ensuring effective cleaning results.
- Cost-Effective: Affordable maintenance solution for HVAC professionals.
