Pipe Cooling High Voltage Ex Motor - Advanced Industrial Explosion-Proof Solution
When your job needs steady performance in dangerous places, our pipe cooling high voltage Ex motor is the safest and most efficient choice. These ATEX and IECEx-certified motors are made by Tellhow Shenyang Electric Machine Co., Ltd. They have squirrel-cage rotors with bar windings, which make them lighter, stiffer, and more resistant to temperature rise. Our motors can handle high loads in coal mines, oil and gas facilities, chemical plants, and big industry equipment. They can output 160kW to 5000kW of power and 3kV to 13.8kV of voltage. Advanced pipe cooling technology (IC411, IC416, IC511, IC516, IC611, IC616) makes sure that heat is managed well, which extends the life of equipment and keeps it working at its best in Zone 1 and Zone 2 dangerous environments.
Why Choose Our Pipe Cooling Explosion-Proof High Voltage Motors?
Uncompromising Safety in Hazardous Environments
The safety of your building is a must. Our explosion-proof motors are certified to meet the toughest worldwide standards, such as ATEX and IECEx. The strong cage design keeps sources of fire from getting to areas that could explode.
You get a lot of safety features:
- The levels of safety are IP54, IP55, and IP56.
- Temperature values that work for different types of gases
- Buildings that are flameproof and stop interior fires
- Authorized to work in dangerous Zone 1 and Zone 2 areas
Superior Cooling Performance
These motors are different from others because they have a pipe cooling system. Cooling water flows through lines that are carefully designed and built into the frame of the motor. With this method, heat is taken away straight from important parts.
Benefits you'll experience:
- 15-20% lower running temperatures than options that use air cooling
- Performance that stays the same even when temperatures are high
- Insulation systems are under less heat stress.
- Longer life for bearings and windings
The less downtime will be great for your repair team. Fewer problems caused by heat are expected because the heat is effectively removed.
Enterprise-Grade Reliability
Each pipe cooling high voltage Ex motor that is built in our 190,000-square-meter factory goes through strict quality control. Our yearly production capacity of 8 million kW guarantees steady quality and on-time deliveries.
We implement stringent testing protocols:
- Testing for hydrostatic pressure at 1.5 times the maximum pressure
- Measurement of partial flow for insulator integrity
- Analysis of vibrations according to ISO 10816 rules
- Verification of full-load temperature rise
- Path measurement checking that is safe from explosions

Frequently Asked Questions
Q: What makes pipe cooling superior to air cooling for high voltage Ex motors?
A: Pipe cooling gets rid of heat directly from motor parts, which is 20–30% better than air cooling for thermal performance. This is especially important in dangerous places where temperatures may be high and air flow may be limited. Explosive atmospheres can't get into the closed cooling system either.
Q: How often should the cooling system be inspected?
A: We suggest that the cooling lines and joints be visually checked every three months and tested for hydraulic pressure once a year. The quality of the cooling water should be checked once a month to keep the lines from cracking or rusting.
Q: Can these motors operate with variable frequency drives?
A: Yes, our motors are designed for both constant speed and inverter duty applications. When used with VFDs, special attention to insulation systems and bearing protection ensures reliable operation across the full speed range.
Q: What is the typical delivery time for a custom configuration?
A: Standard configurations ship within 8-12 weeks. Custom engineered solutions typically require 16-24 weeks depending on complexity and certification requirements. We'll provide a detailed timeline during the quotation process.
Q: How do you ensure explosion-proof integrity during manufacturing?
A: Every motor undergoes dimensional verification of all explosion-proof gaps and surfaces. We perform tracer gas testing to verify enclosure integrity and document all critical measurements. Final assembly occurs in controlled environments to prevent contamination of explosion-proof surfaces.
Q: What voltage should I select for my application?
A: Voltage selection depends on your facility's electrical infrastructure, cable run distances, and power requirements. Higher voltages reduce current and cable costs for long distances but require more complex switchgear. Our engineering team can help you optimize this decision.
Q: Are these motors suitable for extreme temperature environments?
A: Yes, we offer versions rated from -50°C to +60°C ambient temperature. Cold climate versions include space heaters and special lubricants, while tropical versions feature enhanced ventilation and moisture protection.
