NIBE PLEX 310-80 Plate Heat Exchanger
Description
NIBE PLEX 310-80 is a high-performance and reliable plate heat exchanger designed for demanding heating systems and heat pump systems. The heat exchanger transfers thermal energy between two separate circuits with minimal energy losses, which contributes to optimized operating economy and even temperature maintenance all year round. The compact design makes it very suitable for both new installations and upgrades of existing climate systems.
NOTE! Velltra assures that all NIBE products marketed and sold by us are manufactured in Sweden and contain components of the highest quality, especially adapted for the Nordic market and its challenging climate.
Robust stainless steel construction and brazed design
The plate heat exchanger is made of acid-resistant, high-quality stainless steel that resists corrosion and high mechanical wear during long-term use. The fully brazed design eliminates the need for traditional gaskets, which minimizes the risk of leakage and provides exceptional resistance to pressure variations and temperature changes in demanding heating circuits.
Molded polyurethane insulation for minimal energy losses
To maximize the overall efficiency of the system, NIBE PLEX 310-80 is delivered with a tailor-made, molded polyurethane insulation. The insulation tightly encloses the exchanger and reduces heat radiation to the surrounding space, ensuring that the heat stays in the heating system and contributes to lower energy costs and stable system operation.
High power and optimized heat transfer
With a capacity of up to 60 kW, PLEX 310-80 offers powerful heat transfer for both larger homes, properties and interconnected heating solutions. The optimized embossing of the plates creates a turbulent flow through the channels, which ensures maximum heat dissipation and reduces the risk of deposits and particle accumulation over time.
Warranty and security
Please note that the manufacturer’s full warranty is not applicable for units bought in Sweden and installed outside Sweden.
