Marine Seawater Cooled Cascade Screw Chiller
Product Overview:
The Marine Seawater Cooled Cascade Screw Chiller is a high-performance, energy-efficient refrigeration unit designed for use in marine environments. It is ideal for cooling systems in machining centers and other industrial applications. This chiller features advanced technology, including a semi-closed 5:6 asymmetric twin-screw compressor, which offers higher efficiency compared to traditional models.
Key Features:
1. High-efficiency screw-rotor compressor with 20%-30% better performance than standard units.
2. Patented 5:6 rotor profile design for improved efficiency.
3. Four-step (100%-75%-50%-25%) and three-step (100%-66%-33%) capacity control options.
4. Equipped with 11 bearings and a balance piston for extended bearing life.
5. Designed with efficient silicon steel and special slots for optimal motor efficiency.
6. Built-in oil press system ensures proper lubrication without an external oil pump.
7. High-efficiency double filtration oil separator for maximum heat exchange.
8. Low noise and vibration operation for enhanced user experience.
9. Supports various refrigerants such as R22, R134A, and R407C.
10. All-wave compressor volume ratio (Vi=2.2/2.6/3.0/3.5) for energy-saving operation.

Installation & Transportation Guidelines:
1. **Transportation**: The chiller is packed in a standard wooden box. If hoisting is required, ensure that the package remains intact. Avoid using a forklift after removing the packaging. Units with wheels can be rolled on flat surfaces while maintaining balance. Always handle with care to prevent damage or injury.
2. **Installation**: Choose a location with ambient temperatures between -10°C and 43°C, and relative humidity below 80%. Ensure there is at least 2 meters of space in the wind direction and 1.5–2 meters around the condenser inlet. Place the unit on a solid concrete foundation, and for larger models like DLP-10AS, use damping devices and anchor bolts. Provide enough working space for maintenance and operation.
Pallet Stacker
This category mainly includes Hand Pallet Stacker,Cargolift,Forklift Truck,Electric/Semi-electric Pallet Stacker.
The hydraulic hand pallet stacker is a kind of dynamic and pollution-free manual hydraulic stacking truck equipment. The utility model has the advantages of stable lifting, compact structure, flexible transportation, simple operation, small semi diameter of rotation, etc. It is used for cargo handling and stacking in factories, workshops, warehouses, stations, docks, etc. It is more suitable for those sites with fire and explosion protection requirements (such as printing workshops, oil depots, docks, warehouses, etc.). If it is combined with pallet containers, containers, etc., it can achieve unit transportation, effectively reducing collision, scratches and stacking area of parts, reducing handling workload, and improving handling efficiency.Our hand pallet stacker are specially designed for transporting goods in various supermarkets, warehouses, etc. The material is made of reinforced steel, which is durable and beautiful.
