Pharmaceutical plants specify heat exchangers for process, WFI/purified-water utilities, solvent recovery condensers, and HVAC-related process loops. Ohm fabricates to the materials and documentation named on the enquiry.
Specify, do not assume
- Product-contact MOC (often SS 316L — only if you write it).
- Surface finish (Ra) if required — we do not assume electropolish.
- Gasket FDA/USP status if required.
- DQ/IQ documentation if the quality unit needs it — list the deliverables.
Documentation the quality unit should list
- Material test certificates and heat numbers for product-contact parts.
- Hydrotest and pneumatic test records as per the ITP.
- Surface finish inspection method (Ra gauge, profilometer) if Ra is specified.
- Gasket and elastomer compliance statements when FDA/USP status is required.
Utilities vs product side
WFI and purified-water loops often specify SS 316L on the product side with lower-grade steel on the utility side — but only if the drawing says so. Mixed specifications (product side on tubes only vs shell and channels) must be line-by-line on the RFQ. Ohm does not assume hygienic finish on a 'pharma' keyword alone.
Enquiry path
Use the detailed RFQ form with design code, MOC per component, and attach the purchaser datasheet. If validation documentation (DQ/IQ support packages) is required, name the deliverables — we quote what is written, not a generic 'GMP package'.
