DiversiTech® DT-981 Super Change Fast & Easy R22 System Retrofit

Overview

The DiversiTech® DT-981 Super Change™ provides professional HVAC/R contractors with a streamlined solution for converting older R22 systems to modern HFC refrigerants. This 2 oz. vacuum-packed additive acts as a chemical bridge between non-POE based oils (mineral or alkylbenzene) and newer POE-based oils required for refrigerants like R407C and R410A. By creating a stable chemical link between the old and new lubricants, it eliminates the labor-intensive requirement for a full system flush, except in the case of compressor burnouts.

This innovative formula is designed to maximize oil return and heat transfer, ensuring that the new refrigerant performs optimally within the existing hardware. It is specifically formulated to handle the complexities of system changeouts, making it an essential tool for technicians working on dry-charged units or retrofitting older residential and commercial systems.

Why It Matters

Traditional retrofits often require multiple oil flushes and line set cleaning, which consume hours of billable time and expensive materials. Super Change™ dramatically reduces the time spent on-site by allowing the new oil and refrigerant to coexist safely with the original lubricant. This not only saves the contractor significant time but also offers a more cost-effective upgrade path for the end-user while extending the lifespan of the compressor.

What's Included

• 1 x Injectable Hose Assembly

Features & Benefits

• ✓ High Capacity: One can services systems up to 6 tons (20 KW).
• ✓ Efficiency Boost: Enhances heat transfer and oil return, even in systems with long line set runs or significant rises.
• ✓ No Specialized Tools: Can be injected without the need for manifold gauges or complex hardware.
• ✓ Reclaim Safe: Contains no propellants, ensuring that refrigerant remains reclaimable in the future.
• ✓ Moisture Removal: Helps eliminate moisture and oxygen, reducing internal corrosion and restoring lubricant condition.
• ✓ Versatile Application: Replaces the need for line set flush during R22 to HFC conversions.

Applications

• Residential and commercial R22 to R407C or R410A retrofits.
• Dry charged unit installations.
• Systems utilizing drop-in refrigerants that require POE oil.
• High-rise or long-run refrigeration lines where oil logging is a concern.

Technical Specifications

Tradie Pro Tip: If you are working on large commercial systems exceeding 20KW (6 tons), calculate your oil charge first. You will need to add one additional can of Super Change for every liter of oil in the system to ensure a proper chemical link.
