CONTAINERISED SYSTEMS
SNOWKEY from Snowman Group containerised systems are transportable, all-in-one industrial refrigeration units built inside standard ISO shipping containers. These systems are designed for rapid deployment in various industries and remote locations.
Key Features
Plug-and-play functionality: The systems are delivered pre-assembled and factory-tested. They only need to be connected to water and electricity on-site to begin operation, significantly reducing installation time.
Portability: Housed in durable 20 or 40-foot containers, the systems are easy to transport by truck, rail, or ship, making them ideal for temporary or remote projects.
Protected operation: The container provides a protective, weather-resistant shell that guards internal components against dust, moisture, and harsh external temperatures, ensuring stable operation even in extreme climates.
Space efficiency: The compact, integrated design eliminates the need for separate buildings or extensive on-site construction, saving space.
Diverse ice types: SNOWKEY offers systems that produce various types of ice, including flake ice, tube ice, plate ice, and block ice, depending on the application.
Automatic control: The systems feature an outstanding electric control system, often with components from brands like Siemens and Schneider. The system automatically manages ice production and storage, reducing labor needs.
Types of containerised systems
Containerised ice plants: These units produce and store large quantities of ice for various applications. They can include systems for flake ice, block ice, and tube ice.
Containerised automatic ice storage: These systems are used for storing large volumes of ice, with capacities ranging from 18 to 200 tons. They feature automated raking systems to manage ice storage.
Containerised concrete cooling systems: For large-scale construction projects like dams and bridges, these systems use ice to cool concrete. They can include containerised ice-making and water-chilling units.
Containerised water chillers: These units are designed to provide
chilled water for industrial processes.
AMMONIA SCREW PACKAGES
