Cold Air Blower

Water-Based Cold Air Blowers for Industrial Applications

Superior energy efficiency, high flow rates, and reliable outlet pressure.

Sonic closed-circuit Cool-Air Blowers with in-line after cooler deliver consistently high-velocity air from air knives at air temperatures as low as 45° F (7.2° C), where rapid air cooling of thermal set polymers heat treated parts and assorted critical temperature products without liquid cooling methods. They utilize chilled water or water/glycol and require less total energy and space than traditional methods of cooling. Our industrial cold air blower models, available from 3 to 50 HP, combined with a Sonic air knife or Sonic nozzle configuration, reduce product temperatures quickly.

How Cold Air Blowers Maintain Product Quality and Efficiency

A cold air blower is an industrial device that delivers chilled air to various processes, improving temperature control in manufacturing and production environments. Using advanced refrigeration or chilled water systems, these blowers produce cold air from air knives that is directed onto machinery, products, or materials needing cooling. The system works by circulating air through a cooling medium, such as water or refrigerant, which absorbs heat and lowers the air temperature before it is delivered via air knives or nozzles.

‍

Cold air blowers are essential in many industries. Sonic has engineered its Cool Air Systems for a wide range of applications used in food processing, ink coding, plastic sheets, welded products, heat treating, medical devices, laser chambers, and others.

Enhanced Process Efficiency: They provide rapid and consistent cooling, which keeps industrial processes moving at optimal speeds. The ability to quickly regulate temperatures ensures smoother workflows and less time spent managing cooling needs.‍
Versatile Applications: Their adaptability makes them valuable tools for a wide range of industrial temperature control needs, including food processing, automotive, and pharmaceuticals.

How to Select the Right Industrial Diverter Valve

Determining the best valve for your system depends on balancing air volume, pressure, and material characteristics. When these factors align, you achieve smoother performance, higher efficiency, and long-term reliability. The ideal configuration not only maintains consistent airflow and minimizes pressure loss but also enhances energy efficiency across continuous production cycles.

Common Types of Diverter Valves

Flap Type Diverter: Simple, cost-effective valve ideal for low- to medium-pressure systems handling powders, pellets, or airflows requiring gentle redirection.
Plug (Rotor) Diverter: Designed for continuous-duty applications, offering smooth switching between lines with minimal leakage.

Slide or Slideflex Diverter: Provides fast, tight-sealing transitions for high-pressure or high-temperature processes where precision airflow management is essential.

Key Technical Considerations

When specifying an industrial air diverter valve, consider the following engineering factors to ensure long-term reliability:

Material Compatibility: Choose materials suited to your process—aluminum for lightweight efficiency, stainless steel for hygienic or corrosive environments, or coated alloys for chemical resistance.
Actuation & Automation: Sonic offers manual, pneumatic, or automated actuation to integrate with PLC or sensor-driven systems for instant airflow control.

Sealing & Maintenance: Valves are designed with precision-fit components and replaceable seals to maintain efficiency and reduce downtime during maintenance intervals.

Frequently Asked Questions

Can Sonic butterfly valves be used with a Variable Frequency Drive (VFD)?

Yes. Sonic butterfly valves can operate in conjunction with a VFD for blower speed control; however, they can also function as the sole airflow control device. As a low-cost alternative to a VFD, the butterfly valve allows operators to manually fine-tune air velocity and pressure, setting the optimum airflow level during the initial system setup without relying on expensive electronic controls.

What is the Sonic Y-Verter™, and how does it differ from a VFD?

The Sonic Y-Verter™ is a mechanical alternative to Variable Frequency Drive motor controllers traditionally used in blower and air knife systems. It allows rapid, reliable airflow redirection between system branches without changing motor speed, reducing complexity and maintenance requirements compared to VFD-based systems.

When should I use a Y-Verter™ instead of a VFD?

A Y-Verter™ is particularly effective when using standard 3,600 RPM, 60 Hz motors where air control needs can be met through mechanical redirection rather than motor speed modulation. While certain high-speed blower motors (up to 20,000 RPM) may require VFDs with output frequencies up to 330 Hz, many air knife applications can achieve equal or better airflow management with the simpler, more durable Y-Verter™ system.

Are Sonic air diverter valves compatible with other blower systems?

Yes. They can be integrated with most industrial blowers or pneumatic systems, and custom configurations are available for unique operating conditions.
