Established in 2015, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has grown into a leading manufacturer with a 10,000-30,000 square meter factory and over 200 skilled employees. Our Plate Type Heat Exchanger Frame 304 Stainless Steel 15 Plates 2 Pass is engineered to deliver reliable thermal performance in demanding industrial environments. Built with a robust stainless steel frame and precisely manufactured plates, this heat exchanger offers exceptional heat transfer efficiency and long service life.
Product Overview
This unit is a plate-and-frame heat exchanger featuring 15 corrugated 304 stainless steel plates arranged in a 2-pass configuration. The frame is constructed from high-grade stainless steel to resist corrosion and withstand high operating pressures. The 2-pass flow pattern optimizes countercurrent heat exchange, maximizing temperature differentials and thermal efficiency. Ideal for applications requiring compact size and high performance, such as HVAC systems, chemical processing, and food sterilization.
Key Features & Benefits
- 304 Stainless Steel Plates: Corrosion-resistant, food-grade material suitable for a wide range of fluids including water, oils, and mild chemicals.
- 15 Plate Capacity: Provides a balanced surface area for moderate duty heat exchange, while keeping the unit compact and lightweight.
- 2 Pass Design: Enhances heat transfer efficiency by directing the fluids through two passes, increasing turbulence and reducing fouling.
- Robust Frame Construction: Heavy-duty stainless steel frame with tightening bolts ensures leak-proof sealing and long-term mechanical stability.
- Easy Maintenance: Modular plate design allows for quick disassembly, cleaning, and plate replacement without special tools.
- Customizable Connections: Inlet and outlet ports can be configured with threaded or flanged connections to match existing piping systems.

Detailed Product Description
The plate heat exchanger operates by transferring heat between two fluids through thin, corrugated plates. Our 15-plate model offers a heat transfer area typically ranging from 0.5 to 2 square meters, depending on plate geometry. The 2-pass pattern forces each fluid to traverse the exchanger twice, increasing the effective length and improving heat recovery. This design is particularly beneficial when temperature cross occurs or when close temperature approaches are required.
The frame consists of a fixed head plate, a movable tail plate, and guide bars. All frame components are fabricated from 304 stainless steel, ensuring resistance to rust and mechanical deformation. The tightening bolts allow precise compression of the plate pack, which is critical to maintain gasket contact pressure and prevent leaks. Each plate is stamped with a gasket groove to ensure perfect alignment and sealing.
For applications involving aggressive media or high sanitation standards, our stainless steel plates can be passivated and electropolished upon request. The unit can be supplied with various gasket materials to match the chemical compatibility and temperature requirements of your process. Additionally, we offer options for insulated frames, drip trays, and custom port sizes.
Company & Quality Commitment
Qingdao Conqinphi Environmental Technology Group Co., Ltd. has been serving global clients since 2015, with annual exports exceeding US$10-50 million. Our factory, spanning over 10,000 square meters, is equipped with advanced CNC machines and testing facilities. We implement strict quality control at every stage: from raw material inspection to final pressure testing. Our experienced engineering team can assist with thermal design, plate selection, and installation guidance. We have shipped thousands of plate heat exchangers to markets across North America, Europe, Southeast Asia, and the Middle East, earning trust through consistent performance and responsive service.
Every unit undergoes a hydrostatic test at 1.5 times the design pressure, and we provide detailed test certificates. With a dedicated after-sales team, we offer technical support and spare parts availability. We invite you to contact us for a tailor-made solution or to discuss your specific heat transfer challenge.
Frequently Asked Questions (FAQ)
Q1: What is the typical heat transfer area for this 15-plate model?
A: The exact area depends on the plate design (e.g., chevron angle, depth). For our standard plates, the effective area per plate is approximately 0.1-0.2 m², giving a total of 1.5-3 m². Please provide your thermal duty requirements so we can recommend the optimal plate configuration.
Q2: Can I use this heat exchanger for steam heating?
A: Yes, with appropriate gasket material and pressure ratings. For steam applications, we recommend EPDM or FKM gaskets and must confirm the steam pressure/temperature. Our design can handle steam up to 150°C (limited by gasket).
Q3: Are the plates individual replaceable?
A: Absolutely. The modular design allows you to replace a single damaged plate without replacing the entire pack. This reduces maintenance cost and downtime.
Q4: What kind of fluids can be processed with 304 stainless steel?
A: 304 stainless steel is suitable for many fluids including water, glycol, oils, mild acids, and food products (e.g., milk, juice). For highly corrosive fluids (e.g., seawater, strong acids), we recommend 316L or titanium plates – available on request.
Q5: How do I clean the heat exchanger?
A: In most cases, the unit can be opened by loosening the tightening bolts, sliding back the tail plate, and removing the plates for manual cleaning. Alternatively, CIP (clean-in-place) protocols can be used if the system is designed accordingly. We provide a cleaning manual with every shipment.
Q6: What are the shipping dimensions and weight?
A: For a 15-plate frame, approximate dimensions are 500 mm (L) x 200 mm (W) x 500 mm (H), and weight is around 25-35 kg depending on connection type. Exact data will be provided in the technical drawing upon order.
Q7: Do you offer custom plate patterns or special gasket materials?
A: Yes, we can customize the plate corrugation angle (30°, 45°, 60°) to match high viscosity or high pressure applications. We also supply gaskets in HNBR, silicone, PTFE/silicone composite for extreme temperatures or chemical resistance. Contact our sales team with your requirements.
Q8: What warranty do you provide?
A: We offer a standard 12-month warranty against manufacturing defects. Extended warranty options are available upon negotiation. Our factory has a robust quality management system and we stand behind our products.
