Nu-Calgon 4774-0 Coil Gun
The Nu-Calgon 4774-0 Coil Gun is a heavy-duty, hose-end sprayer engineered for high-efficiency application of HVAC coil cleaners. Designed to eliminate the need for manual pre-mixing, this tool utilizes a venturi-style mixing head that automatically blends concentrate with water at five precise dilution ratios: 3:1, 4:1, 6:1, 9:1, and 10:1. The 2-quart reservoir is optimized for high-capacity jobs, while the quick-disconnect feature allows a technician to transition instantly from chemical application to a high-pressure water rinse. This unit is specifically built for use with alkaline and non-acidic concentrates like Nu-Brite and CalClean, ensuring maximum dwell time and deeper penetration into air-cooled condensers and evaporator fins. By maintaining a water pressure between 40 to 60 PSI, the Nu-Calgon 4774-0 provides a consistent stream that carries up to 25 feet, making it a reliable choice for condenser coil cleaning in diverse field conditions.
Key Benefits for Technicians:- Internal Proportioning Head: Provides five mix ratio settings to match the chemical concentration to the level of coil fouling.
- High-Impact Foaming: Includes a dedicated foam wand to increase exposure time on vertical surfaces for superior soil emulsification.
- System Protection: Features a built-in anti-siphon device to prevent chemical backflow into the potable water supply.
- Versatile Spray Control: Equipped with a deflector tip to fan out the spray for broad coverage or a solid stream for reaching deep into multi-row coils.
- Interchangeable Components: Fully compatible with the 4774-1 Coil Gun Probe for 90-degree "inside-out" cleaning of outdoor units.
Can the Nu-Calgon 4774-0 be used with hydrofluoric acid cleaners?
No, this tool is designed for alkaline and non-acidic coil cleaners; acidic solutions will damage the internal components of the mixing head.
Is this sprayer compatible with microchannel coils?
It is generally recommended to verify the specific cleaner's compatibility with microchannel materials, as the gun's pressure and chemical delivery are optimized for standard copper/aluminum fin-and-tube designs.
What water pressure is required for accurate dilution?
The 4774-0 functions best between 40 and 60 PSI. Pressures exceeding 90 PSI may affect the siphon accuracy and should be regulated.
