Why Choose a Screw Water Chiller for Industrial Cooling

You want reliable cooling for your facility. A screw water chiller delivers powerful performance where you need it most. Industrial operations face challenges like high water usage, complex setups, and costly maintenance. The table below shows how this solution tackles these issues and keeps your business running efficiently.

What Is a Screw Water Chiller?

You want a cooling system that delivers consistent results and keeps your operations running smoothly. A screw water chiller stands out as a powerful solution for industrial cooling. This system uses a screw compressor to move refrigerant through a closed loop, ensuring your facility stays at the right temperature for peak performance.

How Screw Compressors Work

A screw compressor uses two interlocking rotors to compress refrigerant vapor. This process starts when the compressor vaporizes the coolant at low gravity and temperature. The coolant then becomes a high-pressure gas. As this gas moves into the cooling chamber, it transfers heat to the chilled water. The thermostatic widening valve controls the flow of vacuum fluid into the evaporator, where the water cools to your desired temperature. The cooled liquid circulates back through the system, keeping your process stable and efficient.

Typical Industrial Uses

You can rely on a screw water chiller in many industries that demand reliable cooling. These systems excel in small- to medium-scale applications. Common uses include:

• Plastics extrusion cooling

• Injection mold cooling

• Plating and anodizing cooling

• Food process cooling

• Pharmaceutical and chemical production

• Commercial printing

• Metal finishing

• Composite manufacturing

• Laser cutting

• Machine tooling and die-cutting

• Semiconductor manufacturing

If your business needs precise temperature control and dependable operation, a screw water chiller gives you the flexibility and reliability you expect.

Benefits of Screw Water Chillers

Energy Efficiency

You want to cut costs and boost your bottom line. A screw water chiller helps you achieve this by delivering outstanding energy efficiency, especially under varying load conditions. The system uses advanced sequencing, load, and parameter optimization strategies to maximize savings. For example, frequency conversion control of the water pump plays a significant role in reducing energy consumption.

Over one summer, you can save up to 650,463 kWh, with sequencing contributing 5.64% to total savings. You also benefit from a novel efficiency model that helps you identify performance losses due to aging or improper operation. By monitoring these factors, you maintain high energy efficiency and keep your cooling performance at its best.

Quiet and Reliable Operation

You need a cooling solution that works smoothly and quietly. Screw water chillers offer a broad cooling capacity range from 80 to 2,000 RT, making them ideal for large operations. You get excellent load adaptability, from 10% to 100%, so your system responds to changing demands without missing a beat.

• Screw chillers operate with fewer moving parts, which means less noise and fewer breakdowns.

• Maintenance costs are 15–20% lower compared to centrifugal models.

• You enjoy reliable operation with less downtime, keeping your facility productive.

The OMC-75WSH model stands out with its semi-hermetic screw compressor, which ensures quiet and stable operation. You can trust this unit to deliver consistent cooling performance in demanding environments.

Low Maintenance

You want to spend less time and money on upkeep. Screw water chillers make this possible with their simple design and robust components. The compressor has fewer moving parts, which means fewer things can go wrong. High-efficiency heat exchangers and advanced control systems further reduce wear and tear.

You benefit from longer intervals between maintenance checks and lower annual costs. The OMC-75WSH features a Siemens PLC control system with self-diagnosis, making it easy to monitor and address issues before they become costly problems.

Safety and Flexibility

You need a cooling system that keeps your facility safe and adapts to your needs. Modern screw water chillers come equipped with multiple safety mechanisms to prevent operational hazards.

The OMC-75WSH model includes protection against high and low pressure, compressor overheating, and flow issues. You get peace of mind knowing your equipment and staff are protected.

Flexibility is another key advantage. You can configure your screw water chiller to use different refrigerants, such as R134a, R407c, or R404a, depending on your operational and environmental needs. The system integrates easily with other cooling and air conditioning setups, making it versatile for a wide range of industrial applications. Customization options let you tailor the unit to your specific requirements, whether you work in plastics, pharmaceuticals, food processing, or metal finishing.

Screw Water Chiller vs. Other Chillers

Centrifugal Chillers Comparison

You want a cooling system that matches your facility’s demands. Centrifugal chillers use dynamic compression to convert kinetic energy into static energy. These machines deliver high efficiency at full load and operate with minimal maintenance. You get a long operational life and reliable performance in environments with constant, high-speed airflow. Centrifugal chillers work best in large commercial buildings and industrial plants where cooling loads remain steady.

If your cooling needs fluctuate, a screw water chiller gives you better energy savings and adaptability. Centrifugal chillers excel when you need maximum output all the time.

Reciprocating Chillers Comparison

You may consider reciprocating chillers for their lower installation costs. These units use pistons to compress refrigerant, but they rely on older technology. You face more frequent maintenance and higher operational costs over time. Screw water chillers feature a rugged design, so you spend less on upkeep and enjoy lower operational costs.

Choose a screw water chiller if you want a system that keeps maintenance simple and costs low.

When to Choose a Screw Water Chiller

You need flexibility and reliability in your cooling solution. Screw water chillers perform best when your facility experiences variable loads or part-load conditions. You benefit from energy efficiency, quiet operation, and easy integration with other systems. If your business requires adaptable cooling for plastics, pharmaceuticals, food processing, or metal finishing, this technology supports your growth.

Choosing a Screw Water Chiller

Key Features to Consider

You want a screw water chiller that delivers reliable cooling and maximizes your investment. Focus on features that drive performance and savings on energy costs. Look for high energy efficiency, proper capacity, and easy maintenance. The right unit helps you reduce energy consumption costs and keeps your operations running smoothly.

Advanced control systems boost operational efficiency and safety. You benefit from monitoring devices that track water flow, parameter verification to prevent abnormal operations, and post-startup inspections that protect your compressor. High and low pressure protection and electrical self-control systems add extra layers of safety.

Manufacturer Reputation

Choose a manufacturer with a strong reputation for quality and innovation. You want a solution that adapts to future needs and meets all regulatory standards. Look for smart controls and eco-friendly refrigerants that help you reduce energy consumption. Consider long-term ROI, including projected savings on energy costs and maintenance.

Check for certifications like UL, CE, CSA, ETL, RoHS, REACH, ISO 9001, and ISO 14001. These show the manufacturer’s commitment to safety and quality.

Sizing and Customization

Get the right size by calculating your total cooling load and peak demand. Use the formula: BTU/hr = Gallons per hr x 8.33 x ΔT°F. Divide BTU/hr by 12,000 to find the cooling capacity in tons, then multiply by 1.2 for safety. Always round up to ensure your chiller meets your needs.

Customization matters. You can adjust the temperature range, control system, and component materials. Choose noise reduction features and tailor the design to your environment. The OMC-75WSH stands out with a temperature range of 5ºC to 35ºC, a semi-hermetic screw compressor, and multiple safety features like high and low pressure protection and compressor overheating protection. You get a unit that fits your requirements and supports your business growth.
