Pressure hoses for cooling systems

Pressure hoses for cooling systems are essential components in industrial production lines, automotive, heat exchange and energy supply systems. Their purpose is to safely and efficiently circulate cooling fluids (e.g. antifreeze) under pressure and at high temperatures. These hoses ensure the continuous functioning of the cooling process, reduce the risk of overheating and help maintain the stability of equipment operation.

Given that these hoses are constantly exposed to heat, pressure, ambient humidity and aggressive substances, their design must be extremely robust and durable. The inner and outer layers are made of high-quality EPDM rubber, which is resistant not only to temperature but also to ozone, UV rays and atmospheric agents. These properties allow the hoses to operate in both closed and open systems under difficult climatic or working conditions.

Use in industrial, automotive and heat exchange systems

Pressure hoses for cooling systems are widely used in automotive engine cooling cycles, heat pumps, heat exchangers, refrigeration units and various industrial equipment lines. These hoses efficiently transport cooling fluids such as ethylene glycol or propylene glycol-based antifreeze. They are also suitable for use in systems requiring thermal stability and high operating temperatures.

Material composition and design for pressurised fluid circulation

The inner layer of the hose is made of black, smooth EPDM rubber, which is highly resistant to heat and various chemicals. The outer layer is made of the same EPDM-based rubber compound, which is resistant to weather conditions, UV rays, ozone and even oil. The construction is further reinforced by a textile mesh, which increases the mechanical strength, pressure tolerance and flexibility of the hose.

Resistance to heat, moisture and chemical influences

Pressure hoses for cooling systems can be used in an extremely wide temperature range from -35 °C to +145 °C. This property is particularly important when using hoses in both cold and extremely hot conditions. EPDM rubber is resistant to vapour, temperature changes and most cooling fluids used in systems. This helps to prevent deformation, cracking or the formation of internal deposits inside the hose.

Fastening, operation and maintenance

These hoses can be used in both stationary and mobile cooling systems. Depending on the diameter and configuration, they can be installed using various fasteners such as clamps, couplings or adapters. Proper installation prevents leakage, ensures tightness and optimal pressure distribution in the system.

Safe integration into closed and open cooling systems

Pressure hoses for cooling systems are suitable for use in both closed systems, where the coolant circulates between the heat source and the heat exchanger, and in open systems, where the fluid is continuously filled or drained. Their versatility allows them to effectively address a variety of technological challenges in different sectors.

Operating characteristics and hose durability

Thanks to their reinforced structure, elasticity and material resistance, these hoses have a long service life even when frequently exposed to high loads. By selecting the right hose for the pressure, temperature and fluid used, unexpected downtime can be avoided and system reliability ensured.

Maintenance solutions for uninterrupted operation

It is recommended to periodically check the outer surface of the hose for wear, deformation, cracks or temperature damage. It is also important to ensure that the hose is not bent at sharp angles, as this will reduce its service life. Regular maintenance contributes to the safe and long-term use of hoses in both industrial and transport systems.

Fast order processing and competitive prices

Pressure hoses for cooling systems are manufactured in the EU to high quality standards and are available in various diameters (16–55 mm), in rolls or in the required length in metres. All Almeida products are delivered quickly to Kaunas, Vilnius, Šiauliai, Panevėžys, Klaipėda and other cities. The price depends on the hose diameter, wall thickness, reinforcement type and operating temperature requirements, but we always strive to ensure the best value for money.
