Imperial Kwik Charge 535C Liquid Low-Side Charger — R-410A Compatible, Fast Vacuum & Metered Flow

Designed for professional service techs, the 535C accepts liquid refrigerant from the cylinder and meters it into the low side of the system at rates up to eight times faster than traditional vapor charging. Its internal metering element and built-in ball check valve control flow, prevent compressor damage, and enable fast vacuum evacuation. The unit works with all fluorinated hydrocarbon refrigerant systems and is especially useful when liquid charging is required for modern blends.

How does the Kwik Charge speed up charging compared with vapor methods?

The 535C feeds refrigerant in liquid form directly to the low side, which moves mass into the system far quicker than introducing refrigerant as a gas. This improves service efficiency and reduces time on the job without needing to heat the cylinder.

• Charging rate up to eight times faster than vapor charging
• Direct liquid feed reduces overall refill time
• No cylinder heating required for fast delivery

Is the device safe for compressors and blended refrigerants?

Yes — the Kwik Charge includes an internal metering element that limits liquid flow to a safe level below the compressor’s capacity, minimizing the risk of liquid slugging. It is suitable for blended refrigerants such as R-410A and all common fluorinated hydrocarbon systems when liquid charging is required.

• Internal metering protects compressors by reducing liquid flow
• Compatible with R-410A and other blended refrigerants
• Allows quick, controlled charging without overpressurizing the system

How does the built-in check valve improve vacuuming and handling?

The Kwik Charge’s ball check valve opens automatically during vacuum pulls to permit rapid, unrestricted evacuation of the cylinder and hose. This feature saves setup time and reduces the chance of trapped moisture or air before charging.

• Automatic check valve opens for fast evacuation
• Prevents backflow and simplifies vacuum procedures
• Ensures a cleaner charge by helping remove non-condensables

What systems and capacities is the 535C appropriate for?

The unit is designed to serve most commercial and residential systems one-half ton and larger, making it versatile for many service calls. Its robust design and straightforward connections let technicians add liquid refrigerant from standard cylinders to manifold low-side ports with confidence.

• Suitable for units 1/2 ton or larger
• Connects to standard charging manifolds and hoses
• Works across a broad range of fluorinated refrigerant types

Who this is for: HVAC and refrigeration technicians who regularly service systems that require liquid charging — including modern blended refrigerants — and professionals who need a faster, more reliable way to fill systems without heating cylinders or risking compressor damage. The Imperial 535C is a practical, trade-grade tool for service vans, shop benches, and on-site repairs where time, safety, and compatibility matter.
