Product Description

The products have been tested by the National Air-Conditioning Equipment Testing Center and are primarily large-scale commercial/industrial water-cooled screw chiller units, supporting customization and multi-unit parallel operation.

I. Product Positioning and Specifications

Cooling capacity range: 65 kW ~ 1300 kW (Single / Dual / Multi-Compressor)

Outlet water temperature: 5~15℃ (Standard), customizable Low temperature of 0~5℃ 、 ±0.5℃ high-precision constant temperature

Applicable to: large shopping malls, hotels, office buildings, hospitals, data centers, electronics/chemical/pharmaceutical manufacturing workshops, and centralized chilled water supply systems for central air conditioning.

II. Core Structure

Compressor: Semi-hermetic high-efficiency screw (5:6 asymmetric rotor), spool valve Stepless energy regulation from 10% to 100%

Heat exchanger: Shell-and-tube evaporator + condenser , high-efficiency internal-thread copper tubing, stain-resistant and with strong heat exchange

Control System: PLC + Touch Screen , full Chinese interface, supports 485/MODBUS, Remote APP, Building Automation

Refrigerant: R134a/R410A Eco-friendly refrigerant

III. Performance Characteristics

High energy efficiency : Standard operating conditions with an EER ≥ 4.8 and an IPLV meeting Tier 1 energy efficiency, delivering even greater energy savings under part-load operation.

Stable and quiet : Low vibration, low noise (70–85 dB), smooth operation, and a service life of 15 years or more.

Intelligent Protection : Multiple protections including high/low pressure, overload, freeze protection, water shortage protection, oil pressure differential protection, and motor overheating protection.

Easy installation : Pre-charged with refrigerant at the factory; only water and power connections are required for commissioning.

IV. Advantages

Water cooling offers high thermal dissipation efficiency, More stable in high-temperature environments

Screw design is resistant to liquid hammer, features a low failure rate, and requires simple maintenance.

Can do Heat Recovery (Refrigeration simultaneously produces domestic hot water)

Supports multi-device collaborative control, ideal for scaling up large-scale projects.

V. Supporting Requirements

External connection required Cooling tower + cooling water pump + chilled water pump , suitable for large-scale projects with access to cooling water.
