The Problem of Overheating in Telecom Cabinets
Causes of overheating
You might think a telecom cabinet is safe once you close the door, but heat can build up fast inside. Here are some common reasons why cabinets overheat:
- Poor airflow blocks cool air from reaching hot spots.
- Blocked vents or failed fans stop air from moving, trapping heat.
- High outside temperatures push the cabinet’s internal temperature above safe limits.
- No real-time temperature sensors mean you don’t get alerts when things heat up.
- Humidity can speed up battery wear, making the cabinet even warmer.
- Sometimes, people tamper with cooling systems, which can make things worse.
If you don’t have good airflow or monitoring, heat sneaks up on you. That’s why many operators use temperature and humidity sensors to catch problems early.
Risks to telecom equipment
Heat is the enemy of your telecom gear. When temperatures climb, equipment starts to struggle. Here’s what can happen:
- Power supplies, amplifiers, and batteries can fail or shut down.
- Every time the temperature goes up by 18°F, your equipment’s life gets cut in half.
- Batteries lose backup power faster, and cooling system compressors can break from overwork.
- Overheating can cause network-wide outages and more maintenance calls.
Telecom electronics need stable temperatures. If you ignore heat, you risk expensive repairs and shorter equipment life.
Challenges in managing heat
Keeping cabinets cool isn’t always easy. You face a lot of challenges:
- Cabinets sit in all kinds of places, from busy city streets to remote outdoor sites.
- Outdoor cabinets deal with heat, storms, and even vandalism.
- New technology means more power in smaller spaces, which creates more heat.
- You need to balance cooling, noise, and looks, especially in public areas.
- Reliable Telecom Cooling is critical because failures can affect emergency services and cost a lot to fix.
Operators use active cooling like air conditioners and fan filter units to keep things running smoothly. Good thermal management helps your equipment last longer and saves you money on repairs.

If you run cabinets in harsh or remote locations, the investment pays off by reducing downtime and repair costs.
How DC Air Conditioners Work
Let’s break down how these units keep your cabinet cool:
- Temperature sensors inside the cabinet watch for rising heat.
- When it gets too warm, the DC air conditioner turns on.
- The evaporator coil inside the cabinet absorbs heat from the air.
- The refrigerant in the coil evaporates, carrying heat away.
- The compressor (powered by 48V DC) moves the hot refrigerant to the condenser outside.
- The condenser releases the heat to the outside air.
- The cooled refrigerant cycles back to the evaporator, and the process repeats.
- Air circulates inside the cabinet, keeping the temperature even.
This closed-loop system keeps outside air, dust, and moisture from getting in. You get precise temperature control, even if the weather outside changes.
Targeted Cooling for Enclosed Spaces
You need cooling that works exactly where your equipment sits. DC air conditioners give you that. They focus all their power on the inside of your cabinet, not the room around it. This means your sensitive electronics stay cool and safe, even if the sun is beating down or the air is full of dust. You get peace of mind knowing your network won’t go down because of heat.

Fan Filter Units
Recommended products
Airflow
You want your telecom cabinet to stay cool and clean. Fan filter units help you do just that by moving fresh air through your cabinet and pushing out the hot air. These units use a fan to pull in outside air, which passes through a filter before reaching your equipment. This process keeps dust and moisture away from your sensitive electronics.
Fan filter units come in different sizes and airflow capacities. Smaller models, which are common in telecom cabinets, usually provide airflow between 40 and 60 m³/h (about 25 to 37 CFM). If you need more power, larger units can deliver up to 1200 m³/h. Here’s a quick look at typical airflow rates:
| Fan Filter Unit Model | Airflow Rate (m³/h) | Airflow Rate (CFM) |
|---|---|---|
| Filter fan – size 2 (230 V) | 42 to 55 | 25 to 32 |
| Filter fan – size 2 (120 V) | 48 to 63 | 28 to 37 |
| Larger/cleanroom-grade units | 600 to 1200 | 353 to 706 |
You can pick the right size for your cabinet, so you get just the right amount of airflow.
Suitability
Fan filter units work best in mild climates or indoor spaces. If your telecom cabinet sits in an office, a server room, or a shaded outdoor spot, these units are a smart choice. They handle lower heat loads well and keep your equipment safe from dust and debris. You might use them for:

Telecom Cooling Decision Guide
Choosing the right Telecom Cooling solution can feel overwhelming, but you can break it down step by step. Let’s walk through the main factors you should consider before making your decision.
Cabinet Size
Start by looking at the size and shape of your telecom cabinet. A small cabinet with a wide, short design often works well with a fan filter unit. If you have a tall, narrow cabinet or a large enclosure packed with equipment, you might need a side-mounted or top-mounted DC air conditioner. Bigger cabinets usually have more surface area, which helps with heat conduction, but they also generate more heat. Linkewell offers both compact fan filter units and powerful cabinet air conditioners to fit any cabinet size.
Location
Think about where your cabinet sits. Is it indoors, in a clean office or server room? Or is it outside, exposed to sun, rain, dust, or even salty coastal air? For mild, indoor environments, a fan filter unit is usually enough. If your cabinet faces harsh weather, high humidity, or extreme temperatures, you need active cooling. DC air conditioners from Linkewell are built for tough outdoor sites, deserts, and coastal areas. They keep your equipment safe by blocking out dust and moisture while maintaining a stable temperature.
Heat Load
Check how much heat your equipment produces. Add up the power consumption of all devices inside the cabinet, then factor in extra heat from sunlight or nearby machines. Industry best practice says you should pick a cooling system that can handle your total heat load plus about 20% more. For example, if your cabinet gets up to 116 °F, you want a system that brings it down to around 95 °F. Linkewell’s DC air conditioners and fan filter units come in different capacities, so you can match the right model to your needs.
Budget
Budget matters for every project. If you need a cost-effective solution for a small or less demanding cabinet, fan filter units are a smart pick.
