Screw Type Compressor Air Cooled Chiller for Printing Shops and R410a Cooling

Product Overview

Chiller

Simply put, a chiller in a cleanroom engineering project is like the "refrigeration heart" of the cleanroom’s central air conditioning system. Its working principle is similar to that of an outdoor unit of a household air conditioner: it cools water through a refrigeration system, and then sends the chilled water to the air conditioning terminals and heat-generating equipment in the cleanroom. Supplying cooling to the air conditioner stabilizes the cleanroom’s temperature, humidity and pressure differential, preventing excessive dust and bacteria levels. Cooling the equipment prevents precision instruments from losing accuracy or shortening their service life due to overheating. With a chiller in place, the cleanroom can meet the stringent environmental requirements of production and experiments.

Features at a Glance

• High Precision Temperature Control to Meet Stringent Process Requirements:It can stably control the chilled water temperature within the range of ±0.5–2℃. Combined with a closed-loop pipeline system, it provides a continuous and stable cold source for cleanroom HVAC terminals and process equipment, preventing temperature and humidity fluctuations from affecting product yield (e.g., semiconductor chips, pharmaceutical preparations). It is suitable for ISO Class 5–8 cleanrooms and meets the environmental requirements of GMP standards.
• High Refrigeration Efficiency with Significant Energy Saving & Consumption Reduction:Mainstream screw and scroll chillers have a high COP (Coefficient of Performance). Under partial load conditions, the variable frequency compressor can dynamically adjust the cooling capacity to reduce unnecessary energy consumption.Water-cooled chillers have better heat exchange efficiency than air-cooled equipment, resulting in lower long-term electricity costs. High-end models can integrate waste heat recovery functions to further improve energy utilization efficiency.
• Stable and Reliable Operation with Low Maintenance Costs:The closed-loop cycle design prevents the secondary refrigerant from being easily contaminated and reduces evaporation loss, lowering the risks of pipeline scaling and equipment corrosion.Equipped with a comprehensive protection mechanism (high-low pressure protection, high-low temperature alarm, flow monitoring, fault self-diagnosis), it can avoid unplanned downtime and extend the service life of the equipment. Core components (compressors, heat exchangers) have strong universality, making maintenance convenient.
• Strong Adaptability to Meet Diversified Scenario Needs:Rich types: Including air-cooled chillers (no cooling tower required, flexible installation), water-cooled chillers (large cooling capacity, suitable for high-load scenarios), screw chillers (medium and large cleanroom projects), scroll chillers (small and medium laboratories), etc., which can match the scale and heat load of different cleanrooms.Customizable: Functional modules such as explosion-proof, anti-corrosion and low-temperature (below 7℃) can be configured according to needs, adapting to the special process requirements of different industries such as , electronics and food.
• Reduce Cleanroom System Complexity and Improve Overall Operational Efficiency:As a centralized cold source, it can supply cooling to both the cleanroom air conditioning system and process equipment simultaneously, replacing multiple decentralized refrigeration units, simplifying pipeline layout and control systems. Stable cold source output helps maintain the cleanroom pressure differential gradient, avoiding airflow disorder and contamination risks caused by local temperature fluctuations.

Technical Specifications

Why Chillers Are Important in Cleanroom HVAC Systems

Why Chillers Are Important in Cleanroom HVAC Systems

In cleanroom facilities, stable temperature and humidity are essential for maintaining product quality and process consistency. Chillers provide the cooling source for HVAC systems and process equipment, helping maintain environmental conditions required by ISO 14644 and GMP guidelines. Proper chiller selection can improve system stability, reduce energy consumption and support long-term cleanroom operation.

Main Specification for Chiller

Cleanrooms typically require multiple, independent water systems with precise temperature control.

Note:A single chiller may serve one loop,or dual-temperature chillers may supply both chilled and reheat water simultaneously.

HVAC System Integration

This water chiller unit supports integration with:

• Air Handling Units (AHU)
• Fan Filter Units (FFU)
• Ducting Systems
• Air Distribution Networks
• Building Management Systems (BMS)
• Temperature and Humidity Control Systems

The integration helps create a stable environmental control system for cleanroom facilities.
