Plate heat exchangers, featuring a modular, corrugated-plate structure, are compact, customizable, and corrosion-resistant devices with high heat transfer efficiency, low pressure drop, and easy maintenance, suitable for a wide range of fluids and applications in various industries, providing cost-effective operation.

Plate heat exchangers are widely used in various scenarios. In HVAC systems, they handle district heating, cooling, and air – conditioning. In the industrial sector, they play crucial roles in power generation, chemical processing, food and beverage production, and pharmaceutical manufacturing, such as equipment cooling, chemical reaction temperature control, and food sterilization. For renewable energy, they are applied in solar water heating and ground – source heat pump systems. Additionally, they are essential in the marine industry for power system cooling and domestic hot water supply, as well as in data centers for equipment heat dissipation, all due to their high efficiency and compact design.

At Grano, we ensure unrivaled quality in our plate heat exchangers through a holistic approach. We start by sourcing top – tier materials like high – grade stainless steel and titanium, rigorously inspecting each batch for chemical composition, mechanical properties, and surface finish. In manufacturing, our advanced facilities and skilled technicians combine automated precision for plate forming and manual expertise for adhesive pad application, strictly following protocols to guarantee consistent quality. With such meticulous attention at every stage, Grano plate heat exchangers are your reliable choice for outstanding performance and extended lifespan.

faq

Q1
What is a plate heat exchanger and how does it work?

A: A plate heat exchanger has thin, corrugated metal plates with gaskets between them. Hot and cold fluids flow through alternating channels, and heat transfers across the plates. The corrugated design boosts surface area and flow turbulence, making heat transfer more efficient.
Q2
Where are plate heat exchangers used?

A: They're used in many industries. In food and beverage, for pasteurizing and cooling. In HVAC for temperature control. In chemical plants for process cooling and heating. Also in power generation and marine engine cooling.
Q3
How to maintain a plate heat exchanger?

A: Regularly clean it to remove dirt and scale, using suitable cleaning agents. Check and replace worn gaskets to avoid leaks. Monitor pressure drop and temperature differences to spot problems early.
Q4
What materials are used for the plates?

A: Stainless steel is common for its corrosion resistance. Titanium works in highly corrosive situations. Nickel alloys suit extreme conditions. Special coatings can also protect plates.
Q5
Can plate heat exchangers handle high pressure and temperature?

A: Standard ones are for moderate pressure (up to 25 bar) and temperature (up to 250°C). Special models can handle more, using thicker plates, reinforced frames, and heat - resistant materials. But going over limits risks safety and efficiency.
