Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a leading manufacturer specializing in heat transfer solutions since 2015. With a factory spanning 10,000-30,000 square meters and over 200 skilled employees, we deliver high-performance Gasketed Plate Heat Exchangers specifically engineered for HVAC systems. Our model, constructed from 304 stainless steel, handles up to 10 Bar pressure and 180°C temperature, featuring flanged connections for easy integration. This heat exchanger is designed to maximize thermal efficiency while minimizing energy consumption, making it an ideal choice for commercial and industrial HVAC applications. Backed by rigorous quality management systems (ISO9001, ISO14000, OHSAS18001, and others), we ensure every unit meets international standards.
Key Features & Technical Specifications
- Material Excellence: Plates made of 304 stainless steel, offering excellent corrosion resistance and durability in water/glycol mixtures common in HVAC systems.
- High Pressure & Temperature Rating: Rated for 10 Bar (145 psi) and 180°C (356°F), suitable for district heating, cooling, and heat pump applications.
- Flanged Connections: Standard flanged inlets/outlets (PN16/PN10 compatible) simplify piping installation and reduce leakage risk.
- Efficient Heat Transfer: Herringbone plate pattern generates turbulent flow, increasing heat transfer coefficient by up to 5 times compared to shell-and-tube designs.
- Gasket Options: Available with NBR, EPDM, or Viton gaskets to suit different fluid types and temperature ranges. Clip-on or snap-on gasket design for easy replacement.
- Compact Design: Modular frame allows capacity expansion by adding plates; footprint is 30-50% smaller than equivalent shell-and-tube exchangers.
- Low Maintenance: Easy to disassemble for cleaning and inspection; gaskets are replaceable without special tools.
- Customizable: Plate count, port size, and frame material can be tailored to specific project requirements.

Benefits for Your HVAC System
- Energy Savings: The high turbulence design reduces fouling and maintains high heat transfer efficiency, lowering pump energy consumption by up to 20% compared to conventional units.
- Space Efficiency: Up to 50% smaller footprint than shell-and-tube exchangers, freeing up valuable mechanical room space.
- Easy Maintenance: The bolted frame allows quick access to plates for cleaning or replacement, minimizing downtime.
- Long Service Life: 304 stainless steel plates resist corrosion from treated water, glycol, and chemical additives commonly used in HVAC systems.
- Flexibility: The modular design enables capacity changes by adding or removing plates, ideal for phased projects or future expansions.
Frequently Asked Questions
Q: What is the typical lead time for this heat exchanger?
A: Standard lead time is 15-25 working days, depending on the order quantity and customization. For urgent projects, we can expedite production upon request.
Q: Can this heat exchanger be used with seawater or aggressive fluids?
A: The standard 304 stainless steel is suitable for fresh water, glycol, and mild chemicals. For seawater or highly corrosive fluids, we recommend titanium or 316L plates – please consult our sales team.
Q: How do I choose the right gasket material?
A: NBR is suitable for oil-free water and temperatures up to 120°C. EPDM works well with water/glycol and higher temperatures. Viton is recommended for high-temperature applications up to 200°C or with aggressive chemicals. We can help you select the best option.
Q: Is the flanged connection compatible with ANSI or DIN standards?
A: Yes, we offer flanged connections in ANSI (150#), DIN PN16, or GB standard as per your requirement. Please specify the standard when ordering.
Q: What is the maximum number of plates I can add?
A: The maximum plate count depends on the frame size. For our standard HVAC range, we can accommodate up to 250 plates per unit. For larger capacity, we can also provide multiple units or custom frames.
Q: Do you provide thermal design calculations?
A: Yes, our engineering team can perform detailed thermal and hydraulic calculations based on your process parameters (flow rates, inlet/outlet temperatures, pressure drop limits). We provide a selection report free of charge for confirmed orders.
Q: How do I clean the plates if fouling occurs?
A: The unit can be easily disassembled. Plates can be cleaned using a soft brush and mild detergent, or in-place CIP (clean-in-place) systems are supported. We also offer cleaning services and spare parts.
