Introduction to air-cooled low-temperature freezer

1. Low-temperature freezer is a refrigeration system, water system, electrical system, the core of which is the refrigeration system, which is composed of compressor, evaporator, condenser, and expansion valve. The air-cooled box-type chiller is a chiller that dissipates heat from the environment through one or more external rotor fans because its condenser (radiator) is fin-type.
2. Core advantages of air-cooled chiller: It comes with a refrigeration system, water pump, water tank, and control system. Customers can install it by themselves when it arrives at the customer's site. It can be used in areas where water is scarce and cooling water is inconvenient.

Application fields

With the development of modern science and technology and the diversified requirements of products, some processes and equipment cannot be met by normal temperature water, such as pharmaceutical chemicals, food and beverages, special electronic materials, etc. These high-end industries often need low-temperature freezers to meet process requirements. Dawoxi low-temperature freezers use foreign top-level brand compressors and advanced process structure design to meet some low-temperature freezing requirements within -40 degrees.

Freatures of refrigeration products

1. The temperature control system adopts a microcomputer controller with a simple and generous interface, intuitive and easy operation, and all kinds of operating indication conditions are clear at a glance. A wide temperature range of -5℃ to -40℃ can be adjusted arbitrarily.
2. The core component compressor adopts internationally renowned brands such as Denmark DANFOSS, Germany Bitzer, France Taikang, and the United States Copeland, which is a reliable guarantee for the operation of the unit.
3 The core refrigeration accessories adopt international brand components such as Denmark Danfoss, the United States Emersonguo and domestic top suppliers.
4 The pipeline connection system can be configured according to the requirements of the customer, galvanized pipes, plastic pipes, stainless steel and other materials.
5 The fluid equipment adopts well-known domestic brands, such as: Hangzhou Nanfang, Denmark Grundfos, Germany Wilo, Hangzhou Xinjie, or imported brand water pumps or special customization according to process needs.
6 The electrical appliances adopt internationally renowned electrical components such as LS Schneider Siemens Omron, etc., and no special machine room is required.
7 It comes with a cooling system, cooling water pump, freezing water pump, and water tank, which is easy to move and can be used after turning on. Suitable for areas with scarce water resources and mobile occasions.
8. The fully automatic intelligent control system controls water temperature, high temperature alarm, water flow, fault signal alarm output, and can be customized for remote control
. 9. It can meet the needs of industrial production for 24-hour continuous uninterrupted production for process cooling sources.
Note: The company provides on-site selection in the early stage to assist customers in choosing the appropriate model and process flow planning.
