Introduction of water-cooled box-type chiller
The open chiller is mainly composed of a compressor, evaporator, condenser, electronic control system, and refrigeration accessories. The open chiller only has a complete refrigeration and control system, and its water system is not perfect. Because the unit does not have a water tank or water pump, customers need to match it according to their actual situation.
Advantages: Since the open chiller does not have a water tank or water pump, it is convenient for customers to select the water tank volume, water pump head, etc. according to actual needs. Unlike the closed box chiller, it is not limited by space. Therefore, it can be better matched according to the different equipment requirements and process requirements of customers.
Application areas
Davosi water-cooled box-type chillers are widely used in plastic molds, electronic equipment, chemical equipment, welding equipment, surface treatment, ultrasonic, coating industries, etc. They can accurately control the heat generated by modern industry, improve production efficiency, and ensure production quality. There are many varieties and complete specifications.
Product features
1. The chiller control system adopts a microcomputer controller with a simple and elegant interface and intuitive and easy operation. A wide temperature range of 5℃ to 35℃
2. The core component compressor can be made from internationally renowned brands such as Denmark's DANFOSS, Japan's Sanyo, Daikin, and the United States' Copeland, which is a reliable guarantee for the unit's operation.
3. The core refrigeration accessories are international brand components from Denmark Danoss, America Emersonguo and other domestic and foreign top suppliers.
4. The electrical appliances adopt internationally renowned electrical components such as LS, Schneider, Siemens, Omron, etc., and no special machine room is required.
5. The internal pipes of the machine are made of PCV/PPR/galvanized pipes or stainless steel pipes, which can be selected according to customer needs. The pipes are insulated with 25mm thick PE insulation cotton to prevent the loss of cooling capacity and the generation of condensed water on the pipes.
