  • CE-LVD EN 62233:2008

Product Features

  • Dual-channel independent cooling: supports simultaneous heat dissipation of two water-cooled charging guns, with a dual-channel cooling capacity of up to 20kW to meet high-power charging needs.
  • Intelligent temperature control: The PID algorithm precisely adjusts the coolant temperature . When the ambient temperature is -25℃ ~ 45℃, the temperature of the 1500A + 1500A dual-channel charging gun is effectively controlled between 5℃ and 65℃, ensuring the normal operation of the high-power charging system .
  • Safety protection: It has multiple protections such as low flow alarm (reminder for filter element replacement) , over-temperature protection (stop at ≥75℃), insulation monitoring (alarm when resistivity ≤5MΩ・cm), etc.
  • Low noise design: When working at full load, the noise is only 60dB/m, running quietly without disturbing the environment.
  • Modular design: easy to maintain, and the resin in the deionization tank can be quickly replaced.

Application Scenarios

Applications

Cooling and heat dissipation control of high-power charging systems for shore-based charging station

Technical Advantages

  • Dual-channel synchronous heat dissipation: A single device is compatible with single-channel and dual-channel heat dissipation functions, and can provide heat dissipation for one or two MCS charging guns at the same time without the need for additional equipment, reducing the deployment cost and space occupation of the charging station cooling system, and efficiently adapting to multi-gun concurrent charging scenarios.
  • Dual heat dissipation guarantee: Combining closed-loop water circulation and forced air cooling technology, the finned condenser and high-volume fan can quickly remove the heat of the circulating water, with a significant cooling effect. It can continuously meet the heat dissipation needs of the charging gun when working at high load, avoiding the impact of charging efficiency due to overheating of the equipment.
  • Stable insulation performance: The deionizer continuously purifies the cooling water, ensuring a coolant resistivity of ≥ 5 MΩ・cm. This prevents safety issues such as short circuits caused by conductive water quality . A conductivity meter monitors water quality in real time, providing an alarm when the water exceeds the standard, preventing potential safety hazards in advance. • Full-condition monitoring: Real-time monitoring of multi-dimensional parameters such as flow, temperature, pressure, and water quality. Abnormal data can be promptly fed back through instrument display and external communication, allowing operation and maintenance personnel to quickly locate problems and reduce the risk of equipment failure and downtime. • Dual-mode control: supports direct control by the local main control board and remote scheduling by an external host computer. It can not only meet the independent operation and maintenance needs of a single device, but also be integrated into the overall control system of the charging station to achieve centralized and intelligent management. • Standardized piping design: Clearly specifies piping specifications, bend radius, and connection methods to reduce flow shortages and pressure loss caused by improper installation. 304 stainless steel connectors are highly compatible with PA12 nylon tubing, offering easy installation and excellent corrosion resistance, extending piping service life.
