Product Introduction

Unlike comfort air conditioners, a telecom cabinet air conditioner must operate continuously, handle high sensible heat loads from electronics, adapt to unstable power conditions, and support remote monitoring.Hisurp develops industrial-grade solutions to meet these requirements with dependable cooling, intelligent control, and flexible customization.

Designed for Telecom and Network Infrastructure

Modern telecom sites often contain sensitive equipment such as:

communication cabinets
transmission devices
power supply systems
network control equipment
battery backup systems
railway communication electronics

These systems generate heat all year round. If internal temperature and humidity are not properly controlled, equipment may suffer from signal instability, shortened lifespan, unexpected shutdowns, or costly maintenance issues.

Hisurp’s telecom cabinet air conditioner is specially engineered to maintain a safe indoor climate and support the continuous operation of mission-critical communication infrastructure.

Key Features of Hicon Telecom cabinet air conditioner

High Energy Efficiency Ratio

The unit uses high-efficiency fully sealed rotary or scroll compressors, optimized heat exchangers, and carefully matched refrigeration components. With an EER above 3.0, it helps reduce operating costs while maintaining stable cooling performance.

Energy-Efficient Operation

Telecom rooms and base stations mainly generate sensible heat from electronic devices. Hisurp’s unit is designed with large air volume and small enthalpy difference, reaching a sensible heat ratio above 85%. This allows efficient heat removal without making the room excessively dry.

Year-Round Cooling Performance

Communication rooms require cooling in summer, transitional seasons, and winter. Hisurp telecom cabinet air conditioners are equipped with special low-temperature operation measures to ensure stable refrigeration even in cold conditions.

Dual Cooling and Heating Control

The system includes independent preset temperature control for both cooling and heating. In cold regions, the unit can provide winter heating or preheating to help maintain a proper operating environment for equipment.

Optional Dehumidification

In humid climates such as southern China, Southeast Asia, coastal regions, and river areas, excessive moisture can threaten sensitive electronics. Optional humidity sensing and electric heating functions enable deep dehumidification when needed.

Fresh Air Cooling Option

To further reduce energy consumption, the system can be equipped with a fresh air cooling mode. When outdoor conditions are suitable, the unit can automatically switch to an energy-saving operation strategy while still considering humidity control and equipment safety.

Dual Unit Switching

For remote or unattended telecom sites, Hicon offers dual-unit rotation and backup operation. This design supports main/standby switching, load sharing, and fault linkage, improving system safety and reducing downtime risk.

Auto Restart After Power Failure

In locations where the power grid is unstable, the air conditioner can automatically resume previous operating status after power is restored.

Remote Monitoring with RS485

The telecom cabinet air conditioner supports RS485 communication, allowing remote monitoring and control. This includes:
remote temperature and humidity detection
remote fault and status reading
remote on/off control
remote parameter adjustment

Intelligent Microcomputer Controller

The unit uses a specially developed microcomputer controller with a large-screen text display, strong communication capability, and support for multi-unit networking. This helps reduce operation and management costs for telecom operators.

Automatic Fault Diagnosis

Built-in fault diagnosis and code display functions help maintenance teams identify problems quickly. Fault signals can also be transmitted to remote monitoring systems for faster service response.

When should I use an AC unit over a fan?

Choosing between a fan and a Telecom Cabinet Air Conditioner depends on heat load, environmental conditions, and reliability requirements.
Use an AC unit when:

Heat load is high (continuous operation of electronic devices)
Ambient temperature exceeds safe equipment limits
Humidity control is required (coastal, tropical, or rainy regions)
Equipment must run 24/7 without interruption

Fans are only suitable when:

Heat load is low and intermittent
Ambient air is clean, dry, and within acceptable temperature range
No strict temperature or humidity control is needed

In most telecom base stations and outdoor cabinets, fans alone cannot ensure stable performance, making industrial-grade air conditioning the more reliable solution.

What are typical components in these units?

Telecom Cabinet Air Conditioner is built with industrial-grade components designed for continuous operation and harsh environments.
Core Cooling Components

Hermetic rotary or scroll compressor
High-efficiency condenser and evaporator
Expansion device and refrigerant circuit

Airflow & Heat Management

High-performance fans for stable airflow
Optimized air ducts for efficient heat removal

Control & Protection System

Microcomputer controller with temperature precision (±1℃)
Multi-level protection (over-voltage, over-current, high/low pressure)

Optional Functional Modules

Electric heater for low-temperature environments
Humidity control and dehumidification system
Fresh air cooling module for energy saving

What are typical installation and maintenance requirements?

Proper installation and routine maintenance are essential to ensure long-term performance and reliability.
Installation Requirements

Select appropriate mounting type (side/top mount depending on cabinet design)
Ensure proper sealing to prevent dust and moisture ingress
Provide stable power supply within voltage tolerance (±20%)
Ensure sufficient airflow clearance for heat exchange

Routine Maintenance

Clean or replace air filters regularly
Inspect condenser and evaporator for dust buildup
Check electrical connections and protection systems
Monitor system performance (temperature, noise, vibration)

Preventive Measures

Use anti-corrosion coatings in coastal or harsh environments
Schedule periodic inspections to avoid unexpected downtime

What is the function of remote monitoring?

Remote monitoring is a critical feature for unattended telecom sites, improving operational efficiency and reducing maintenance costs.
Real-Time Monitoring

Track temperature and humidity inside the cabinet
Monitor system running status and performance

Fault Detection & Alerts

Automatic fault diagnosis with error codes
Immediate alarm transmission to control centers

Remote Control
