Our stainless steel gasket plate heat exchanger (PHE) is a high-efficiency, modular, and fully maintainable heat transfer equipment, engineered for optimal thermal performance in the most demanding industrial environments. Manufactured with premium stainless steel materials, precision-formed plate packs, and high-reliability gasket sealing systems, it delivers industry-leading heat transfer efficiency, exceptional corrosion resistance, and long-term stable operation under high pressure, high temperature, corrosive media, and continuous heavy-load working conditions.

Fully compliant with PED 2014/68/EU, ASME BPVC Section VIII, ISO 9001, and CE international standards, our heat exchangers are widely used in chemical, petrochemical, food & beverage, pharmaceutical, marine, power, HVAC, and pulp & paper industries worldwide. It is the ideal heat transfer solution for harsh, demanding industrial environments that require high efficiency, reliability, and easy maintenance.

• Adopts precision-stamped herringbone corrugated plate structure, with optional 30° (low pressure drop, high flow) / 60° (high turbulence, high heat transfer) corrugation angles, which forms strong turbulent flow of the medium at low flow velocity, eliminating heat transfer dead zones and boundary layer thermal resistance.
• The heat transfer coefficient can reach up to 7000 W/(㎡·K), which is 3-5 times higher than traditional shell & tube heat exchangers, with 60% smaller footprint and 40% lower weight, achieving maximum heat transfer efficiency with minimal space and investment.
• Ultra-thin 0.4mm-1.0mm stainless steel plate with strict ±0.02mm thickness tolerance, minimizing thermal resistance while ensuring structural strength, further enhancing heat transfer performance and reducing energy consumption of the entire system.
• Professional thermal design via HTRI & Aspen EDR software, customized flow channel and plate configuration according to your specific working conditions, ensuring optimal heat transfer effect under actual operating parameters.

• Full range of premium stainless steel material options in strict accordance with ASTM A240, EN 10088 international standards, covering all common and harsh corrosive working conditions, with complete Mill Test Certificates (MTC EN 10204 3.1) for full material traceability.

We have more than 18 years of R&D, design, and manufacturing experience in plate heat exchangers, with a dedicated technical team focusing on heat transfer solutions for harsh and demanding industrial environments. We have completed more than 10,000 successful projects in chemical, petrochemical, marine, food & beverage industries worldwide, with rich experience in extreme working conditions such as high corrosion, high pressure, high temperature, and continuous heavy load.

Our thermal engineering team has more than 30 senior engineers with 10+ years of industry experience, using professional HTRI and Aspen EDR thermal calculation software for customized design. We do not provide one-size-fits-all standard products, but design the optimal plate configuration, material solution, and structure according to your actual working condition parameters, to ensure that the heat exchanger achieves the optimal heat transfer efficiency, lowest energy consumption, and longest service life in your specific demanding environment.

We have established a strict quality management system in accordance with ISO 9001, with full traceability from raw material incoming inspection to finished product factory inspection. All stainless steel raw materials are sourced from internationally renowned steel mills, with complete Mill Test Certificates. Each unit undergoes 8 core inspection procedures: material inspection, mold precision verification, plate dimensional inspection, hydraulic pressure test (1.5 times design pressure), penetration flaw detection, gasket sealing test, overall assembly inspection, and final factory performance test, ensuring that each product meets or exceeds international standards.

We have a complete in-house production chain, including mold design & manufacturing, plate stamping, surface treatment, gasket production, and overall assembly, without outsourcing. This not only ensures full control of product quality, but also greatly reduces production costs. Our products have the same or even better performance than international first-tier brands, but the price is only 40-60% of the original, which greatly reduces your equipment investment and total cost of ownership. At the same time, we have a large stock of standard plates and gaskets, ensuring stable and fast delivery for both standard and customized orders.

We have a complete global service network, exporting to more than 60 countries and regions around the world, with local service partners in Europe, North America, Southeast Asia, the Middle East, and South America. Our professional technical team provides 7*24 hours online technical support, and can provide on-site installation guidance, commissioning, maintenance, and training services according to your needs. We provide lifetime technical support for all our products, ensuring long-term stable operation of your equipment in demanding industrial environments.

We not only provide stainless steel gasket plate heat exchanger units, but also provide matching spare parts (plates, gaskets, frames), heat exchanger maintenance and cleaning services, system transformation and upgrading services, and full life cycle management of heat exchange equipment. We can provide you with a one-stop solution from preliminary thermal design, production and manufacturing, installation and commissioning, to later maintenance and upgrading, reducing your procurement cost and communication time.

Our high-efficiency heat transfer design can greatly reduce the energy consumption of the heat exchange system, helping you achieve carbon emission reduction and energy saving goals. All our stainless steel materials are 100% recyclable, and the gasket materials comply with EU RoHS and REACH environmental protection standards, with no harmful substances released during use and disposal. Our products fully meet the global green manufacturing and sustainable development requirements, making them the ideal choice for environmentally friendly industrial projects.

The core difference is the detachable structure: our gasket plate heat exchanger uses a gasket sealing system, which can be fully disassembled for cleaning, maintenance, and capacity adjustment, making it ideal for working conditions that require regular cleaning and process parameter adjustment. Welded heat exchangers cannot be disassembled, and are only suitable for non-fouling, non-maintenance working conditions. Our gasket PHE also has lower maintenance costs and higher flexibility, while maintaining the same high heat transfer efficiency.

Our MOQ is 1 unit for standard models. For standard small and medium-sized heat exchangers, the lead time is 10-20 working days. For large-scale customized units and special material models, the lead time will be confirmed according to the specific design and material procurement cycle. We also support urgent order processing to meet your project construction schedule.

Under normal operating conditions and correct maintenance, the service life of the stainless steel plate pack can reach 10-15 years, and the service life of the gasket is 1-3 years (depending on the working medium, temperature, and pressure). We will provide professional maintenance guidance and regular replacement reminders to maximize the service life of the equipment.
