Chillers for Army Trucks

SANPAR Ethylene Glycol-Water Chillers for Laser Firing Systems on Army Trucks

Laser firing systems mounted on army trucks are vital for various military applications, including targeting, communication, and directed energy weapons. These systems generate significant heat during operation, which can impair performance or even lead to system failure if not effectively managed. To ensure continuous and reliable operation, particularly in extreme environments with temperatures ranging from (-) 20°C to (+) 55°C, SANPAR has developed advanced cooling solutions utilizing an ethylene glycol-water mixture. This coolant blend is specifically designed to handle extreme temperature fluctuations, ensuring efficient heat dissipation for high-power laser systems, even under the most challenging conditions.

The Role of Ethylene Glycol-Water Mixture in Cooling

The ethylene glycol-water mixture is used in SANPAR's chillers because of its superior thermal properties compared to water alone. Ethylene glycol lowers the freezing point of the coolant, preventing it from freezing in cold environments, while also raising its boiling point, allowing the coolant to handle high-temperature conditions without evaporating. This makes it an ideal cooling medium for laser firing systems that are exposed to extreme temperatures, ensuring reliable operation across a broad temperature range.

Key Features of SANPAR Refrigeration based Ethylene Glycol-Water Chillers:

Heat load: 3 kW – 150 kW: Endurance tested: (-) 20°C to (+) 55°C

1. Wide Operating Temperature Range:

   - Designed to operate in environments as cold as( -) 20°C and as hot as (+) 55°C, the ethylene glycol-water mixture prevents freezing at low temperatures and boiling at high temperatures, ensuring the chiller maintains effective cooling performance across diverse operational environments.

   - The system can seamlessly adapt to extreme cold during high-altitude or Arctic missions, as well as desert operations where ambient temperatures may soar above 50°C.



2. Enhanced Thermal Capacity:

   - The ethylene glycol-water mixture has a higher heat capacity than air or pure water, allowing for more efficient heat absorption and dissipation in laser firing systems.

   - This ensures the laser system’s sensitive components, including laser diodes and optics, remain at stable operating temperatures, preventing thermal damage during high-energy firing.



3. Freeze Protection in Cold Environments:

   - Ethylene glycol effectively lowers the freezing point of the coolant, ensuring that the system remains operational even in sub-zero temperatures, which are common in many military environments such as mountainous regions or cold-weather deployments.

   - This freeze protection is critical for laser systems that may be deployed for extended periods in harsh winter conditions, preventing coolant solidification that could cause component damage or system failure.



4. Boil Protection in Hot Environments:

   - In high-temperature environments, such as desert operations, the ethylene glycol-water mixture prevents the coolant from boiling, even under high heat loads. This ensures consistent cooling performance and prevents overheating of the laser system during sustained operation.

   - This is essential for ensuring the high-power lasers maintain their accuracy and output even in extreme heat, where traditional water-based cooling systems might struggle.



5. Corrosion Resistance and Long-Term Stability:

   - The ethylene glycol-water mixture in SANPAR’s chillers contains corrosion inhibitors that protect the internal components of the cooling system and the laser from rust and corrosion over time.

   - The stability of this coolant mixture ensures long-term reliable performance, reducing the need for frequent maintenance or coolant replacement, even in extreme operating conditions.



6. Compact, Military-Grade Design:

   - SANPAR’s ethylene glycol-water chillers are designed with the ruggedness required for military applications, featuring robust construction that can withstand the vibrations, impacts, and harsh conditions encountered in military operations.

   - The compact design allows for easy integration into army trucks, ensuring that the laser system’s cooling infrastructure does not impede vehicle mobility or payload capacity.



7. Advanced Temperature Control System:

   - The chillers are equipped with precise temperature control mechanisms to ensure that the laser firing system remains within its optimal operating temperature range, regardless of external conditions.

   - The system monitors the coolant temperature and adjusts the cooling performance dynamically, providing consistent temperature regulation to maintain peak performance of the laser system.



8. High Efficiency and Energy Conservation:

   - SANPAR’s ethylene glycol-water chillers are engineered to operate with high efficiency, minimizing energy consumption even during extended operations. This is especially critical in military vehicles where power resources are often limited and must be managed carefully.

   - Energy-efficient pumps and advanced heat exchangers are used to maximize cooling effectiveness while reducing the power draw from the vehicle’s electrical system.



9. Safety and Redundancy Features:

   - For mission-critical military operations, reliability is paramount. SANPAR’s chillers include safety features such as over-temperature alarms, flow sensors, and automatic shutdown systems to prevent overheating or coolant flow issues.

   - Redundant cooling paths and backup systems ensure continuous operation, even in the event of a component failure, ensuring the laser firing system remains operational during critical missions.

Applications of Ethylene Glycol-Water Chillers for Laser Firing Systems:

1. Efficient Heat Dissipation:

   - Liquid cooling is significantly more effective than air cooling in terms of heat capacity and transfer efficiency, making it ideal for high-power radar systems that generate substantial heat during operation.

   - By directly cooling critical electronic components, the system prevents overheating, ensuring that the radar maintains optimal performance even during extended missions.



2. High-Energy Laser Systems:

   - High-energy laser systems used for missile defence, targeting, and directed energy weapons generate significant heat during operation. The ethylene glycol-water chillers provide the necessary cooling capacity to handle the extreme heat loads generated during sustained firing.

   - This ensures consistent and reliable performance, preventing the laser system from overheating during critical engagements.



3. Cold Weather and Arctic Operations:

   - Military deployments in cold regions require cooling systems that can handle sub-zero temperatures. SANPAR’s ethylene glycol-water chillers ensure that laser systems remain operational in extreme cold, providing freeze protection that prevents coolant from freezing and causing damage to the system.

   - This is essential for maintaining the functionality of laser systems in high-altitude or Arctic environments where temperatures can drop far below freezing.



4. Desert and High-Temperature Operations:

   - In hot desert environments where ambient temperatures can exceed 50°C, the ethylene glycol-water mixture prevents the coolant from boiling, ensuring continuous cooling and preventing overheating of the laser system.

   - The chiller’s ability to maintain stable operating temperatures in such harsh conditions is crucial for ensuring the laser’s accuracy and power output during extended engagements.



5. Mobile and Armoured Platforms:

   - Army trucks and other mobile military platforms equipped with laser systems benefit from SANPAR’s compact and robust chiller designs. The chillers are designed to operate reliably in the rugged, vibration-heavy environments of military vehicles.

   - Their compact size ensures they can be integrated into these vehicles without compromising space or mobility, making them ideal for rapid deployment and multi-role platforms.
