PWD5402R5

The nVent PWD5402R5 is a robust, roof-mounted air-water heat exchanger engineered for demanding industrial environments. With a substantial cooling capacity of 3400W (at W10/A35 conditions) and operating on a 230V power supply, this unit is designed to maintain optimal temperatures within electrical enclosures, control panels, and other sensitive equipment. Constructed with a galvanized steel housing, powder-coated in RAL 7035, and featuring a heat exchanger made of copper pipe with aluminum fins, the PWD5402R5 offers excellent durability and corrosion resistance. Its IP55 protection rating ensures effective shielding against dust ingress and low-pressure water jets, making it an ideal solution for dusty or humid industrial settings where air cleanliness and ambient temperature fluctuations could otherwise compromise performance. This high level of protection means the unit can reliably operate even in challenging conditions. Installation is simplified by its roof-mounting design, which is particularly advantageous in applications where space is limited on enclosure doors or side panels. This placement also eliminates the need for additional modifications to the enclosure cutout to maintain IP integrity. The integrated thermostat, adjustable between 8 °C and 50 °C (factory set at 35 °C), and solenoid valve provide precise temperature control, ensuring that equipment operates within its specified thermal limits. The maximum permissible operating pressure for the water circuit is 10 bar, and the water inlet temperature range is between 1 °C and 35 °C. Key features and benefits of the nVent PWD5402R5 include: * **High Cooling Capacity:** 3400W to effectively manage heat loads. * **IP55 Protection:** Superior defense against dust and water ingress. * **Roof-Mount Design:** Space-saving installation, ideal for enclosures with limited external mounting options. * **Integrated Temperature Control:** Adjustable thermostat and solenoid valve for precise thermal management. * **Durable Construction:** Galvanized steel housing and copper/aluminum heat exchanger for longevity. * **Wide Ambient Temperature Range:** Operates effectively between +1 °C and +70 °C. * **Versatile Application:** Suitable for dusty environments and high-temperature conditions. This heat exchanger is designed for easy connection, featuring a 3.5-meter cable (3 × 0.75 mm²) for electrical supply and a 13 mm hose nozzle for water pipe connections. By providing localized cooling directly on the enclosure, the PWD5402R5 can reduce overall energy consumption compared to relying solely on ambient room cooling, especially when floor-standing enclosures require independent thermal management. nVent's commitment to quality and innovation in thermal management solutions ensures reliable performance and extended equipment life. The PWD5402R5 is a testament to nVent's expertise in providing effective cooling solutions for critical industrial applications.
