2. Product Introduction
(1). High Energy Efficiency
DARKO Water Cooled Screw Chillers outperform conventional cooling systems with 20-30% higher energy efficiency through advanced screw compressor technology. Their optimized heat exchange design achieves exceptional COP (Coefficient of Performance) ratings, significantly reducing electricity costs for customer in industrial production.
(2). Industrial-Grade Reliability
Engineered for 24/7 continuous operation, our screw chillers feature:
Dual-rotor screw compressors with 50,000+ hour lifespan
Corrosion-resistant stainless steel components
This robust construction ensures minimal downtime in harsh environments from chemical plants to tropical climates.
(3). Eco-Friendly Refrigerant Options
In order to meet the environmental protection requirements of different countries, our chillers are compatible with R407c,R404A, R134a,R507 and etc industrial chiller refrigerant.
(4). Smart Load Adaptability
The 10-100% variable capacity control automatically adjusts cooling output to match real-time demand, preventing energy waste during partial-load conditions. Integrated IoT monitoring enables predictive maintenance alerts via cloud platforms.
(5). Space-Saving Configuration
With 40% smaller footprint than centrifugal counterparts, these modular chillers simplify installation in space-constrained facilities. Optional vertical stack design maximizes floor plan efficiency.
(6). Low Maintenance Requirements
Fewer moving parts and self-cleaning condenser tubes reduce service frequency by up to 60% compared to reciprocating chillers. Removable water panels enable easy access for maintenance without full system shutdown.
3.Versatile Industry Applications:
DARKO Series chillers deliver precision temperature control across diverse industrial sectors, including:
(1). Energy & Chemical: Petrochemical processing, hydrogen production, lithium battery manufacturing
(2). Surface Treatment: Electroplating, anodizing, ultrasonic cleaning, laser engraving systems
(3). Advanced Manufacturing: Plastic injection molding, optical glass production, semiconductor coating
(4). Life Sciences: Pharmaceutical, fermentation, laboratory equipment cooling, food processing
(5). Industrial Maintenance: CNC machining centers, die-casting equipment, printing press thermal regulation
(6). Engineered to integrate seamlessly with industrial cooling systems in demanding environments from mining operations to biotech facilities.
Larger Model ( Two Compressors is optional)
Compressor:
(1). All the DARKO water cooled screw chillers adopt world famous brand semi-hermetic screw and semi-hermetic reciprocating compressors, such as HANBELL, BITZER, REFCOM and etc.
(2). Twin-screw 5:6 gear ratio and advanced linear design, low energy consumption and eco-friendly; good performance, low noise.
(3). According to the cooling capacity need, adopt single compressor or twin compressors circuits system; The compressors can automatically run alternately according to the load change, and balance the running hours of each compressor, which greatly prolongs the chillers working life, and the trouble-free running can reach more than 45,000 hours.
Heat Exchanger
Evaporator
(1). Adopt the internally and externally threaded reinforced tubes.
(2). The inside surface of the copper pipe is threaded, the outside surface of the copper pipe is smooth, so that can ensure the good heat exchange efficient.
(3). The evaporator design running with the latest CAD design technology, CNC production and processing, compact structure , stable performance. And outside insulated with 25mm thick PE insulation, no condensation, less cooling loss.
Copper tubes more thicker and processed into trapezoidal low-assistance tubes to enhance heat transfer capacity. The surface of the copper pipe is smooth, which reduces the water pressure and ieasy to clean and maintain.
DARKO has developed a highly intelligent PLC and PC-level computer control system, which can be used for remote monitoring and control. Simple operation, connect with power supply directly, with lower failure, and high safety factor, easy installation. User can set the parameter as real working need, intuitive and reliable; SIMENS PLC is workable.
Protection System: temperature control switch, high and low pressure switch, overload protection, compressor overheat protector, compressor frequent start protector and abnormal indicator light.
