Frequently Asked Questions (FAQ)
-
Q: What is the maximum operating temperature of this heat exchanger?
A: The standard design temperature range is -196°C to +225°C. For higher temperatures, please contact us for custom solutions. -
Q: Can this unit be used for seawater or brine?
A: 304L stainless steel offers good resistance to chloride stress corrosion cracking, but for high-chloride environments, we recommend upgrading to 316L or titanium plates. Please provide your fluid composition for a recommendation. -
Q: How do I clean the heat exchanger if fouling occurs?
A: The brazed design is not separable for mechanical cleaning. However, chemical cleaning can be performed by circulating appropriate cleaning agents. We recommend installing a filter upstream to minimize fouling. -
Q: What is the typical lead time?
A: For standard units, lead time is 15–20 working days. Custom orders may require 25–30 days. Rush orders are negotiable. -
Q: Do you provide OEM or custom branding?
A: Yes, we offer OEM service with custom labeling, packaging, and even minor modifications to fit your specific requirements. -
Q: How is the heat exchanger tested before shipment?
A: Each unit undergoes a 100% pressure test (air or water) at 1.5 times the design pressure, plus a helium leak test if required. A test certificate is included with every shipment. -
Q: What certifications does your company hold?
A: We are certified under ISO9001, ISO14000, OHSAS18001, and others. Specific certifications can be provided upon request for your project. -
Q: Can I get a sample unit for testing?
A: Yes, sample orders are welcome. We can provide a standard unit or a scaled-down version for your evaluation. Please contact our sales team for details.
