Leak Saver Foam Blaster Evaporator Cleaner
HVAC PROFESSIONAL FORMULA: This Foam Blaster blends high-pressure spray with a delayed foaming action to liquify grime and deodorize dirty coils and drain pans. Field tested and used by HVAC professionals, it is designed for professional use and targets evaporators and condensers.
POWERFUL EXPANDING FOAM ACTION: The spray penetrates deep into the coil and expands into a dirt-liquifying foam, helping restore coil efficiency. It leaves a mild citrus scent as a result of its formulation.
FOR EVAPORATORS AND CONDENSERS: Suitable for evaporators (no rinse) and condensers (light rinse). On evaporators, condensate water from the running unit helps rinse away loosened debris.
Leak Saver AC Coil Cleaner 4:1-10:1 Concentrate
TRIPLE ACTION COIL CLEANER: A powerful detergent, degreaser, and deodorizer formulated for air-cooled evaporators, condensers, and permanent filters. Its Surfactant Technology helps quickly restore peak efficiency.
POWERFUL CONCENTRATED FORMULA: Dilute 4:1 to 10:1 to fit the job. For no-rinse cleaning, dilute 10:1 and rely on condensate moisture for self-rinsing the coil. Compatible with various HVACR systems and materials.
Leak Saver Foam Blaster Evaporator No-Rinse
HVAC PROFESSIONAL FORMULA: A robust coil cleaner designed for evaporators with no rinse required. The high-pressure spray and delayed foaming action work to liquify grime and deodorize coils and drain pans, aiding in restoring cooling efficiency.
POWERFUL ACTIVE EXPANDING FOAM ACTION: The product penetrates deep and expands into a dirt-liquifying foam, effectively cleaning dirty coils and improving performance. Leaves a citrus scent to indicate cleaning action.
FOR EVAPORATORS (NO-RINSE) AND CONDENSERS: Works on evaporators without rinsing; condensers may require light rinsing with water.
ComStar Coil Safe Evaporator Coil Cleaner
POWERFUL GREASE REMOVAL: This cleaner breaks down tough grease, carbon, and grime, liquefying buildup for easier cleanup and maintenance.
INDUSTRIAL STRENGTH & WATER-SOLUBLE: High-performance degreasing power combined with water solubility for easy rinsing on tools, machinery, engines, and more.
SAFE & ECO-FRIENDLY: Phosphate-free, non-corrosive, and safe on hard surfaces—suitable for industrial, commercial, and household use, including residential AC and refrigeration coils.
CANIPHA Coil Cleaning Brush Set
3-Piece Cleaning Tool Set: Ergonomic brushes designed to reach tight spaces around condenser fins and evaporator coils. Made of stainless steel and durable plastics to minimize coil damage while cleaning.
Premium Materials: Built for reliability, with stiff cleaning pins and a soft plastic side to remove debris without harming delicate fins. Encourages thorough cleaning of coils, condensers, and related components.
Easy To Use: Each brush style targets different parts of the coil system, allowing efficient cleaning of inline condensers and fin areas, while protecting coil integrity.
True Evaporator Coil (24″ Height)
Product Overview: Evaporator coil assembly for refrigerators with dimensions 12″ x 12″ x 26″. This unit-type coil is a reference point for coil sizing and fit within standard refrigerator assemblies.
XCEL Dual-Sided Coil Cleaning Brush
ADVANCED CLEANING TOOL: Dual-sided coil cleaning brush with a robust design for evaporator and condenser coils. The metal pins and soft plastic edge allow efficient debris removal without coil damage.
IMPROVED EFFICIENCY: Aids in removing stubborn buildup, contributing to improved airflow and potentially lower operating costs by maintaining better heat exchange.
Buying Guide: Key Considerations For Evaporator Coil Cleaners
- Coil material compatibility: Check if the cleaner is safe for aluminum or copper coils and any coatings used on modern coils. Non-corrosive formulas are preferred for longevity.
- Application method: No-rinse foams are convenient for evaporators in operation, while concentrates may require dilution and rinsing. Consider whether self-rinsing via condensate moisture is feasible for your setup.
- Targeted cleaning action: Foaming cleaners can penetrate tight spaces and loosen grime, while brush tools are ideal for mechanical agitation on fins and coils.
- Environmental and safety factors: Look for phosphate-free, non-toxic formulas that are safe for both professionals and households, with minimal odors or citrus scents if desired.
- Dilution flexibility: Concentrates with adjustable ratios offer cost savings and adaptability across different contamination levels and coil types.
- Versatility: A combination of coil cleaning spray, brush tools, and degreasers can cover evaporators, condensers, and related components like drain pans and filters.
- Ease of use: Consider whether products are field-tested by professionals, include clear usage instructions, and offer no-rinse options to minimize downtime.
Note: The selections above focus on products that are commonly used for evaporator coils in both residential and commercial settings, including specific no-rinse formulas, concentrated cleaners, and accessory brushes designed to protect coil integrity while improving efficiency.
