Industrial Heat Exchangers — Capability Datasheet

Manufacturer

Plot No. 348, G.I.D.C. Manjusar-Savli, Vadodara — Gujarat, India. Founded 2004.

Configurations manufactured

• Shell & Tube Heat Exchangers — Engineered heat-transfer equipment for process heating, cooling, condensing and heat recovery — the primary configuration Ohm manufactures.
• U-Tube Heat Exchangers — Removable U-tube bundles for duties with large tube-to-shell temperature difference or where the bundle must come out for shell-side cleaning.
• Rectangular Cross Flow Box Type Heat Exchanger — Rectangular box-type cross-flow exchangers for duties where this layout is specified on the drawing or process case.
• Double-Pipe Heat Exchangers — Pipe-in-pipe (hairpin) exchangers for high-pressure, high-temperature, or modest-area duties where a full shell-and-tube unit is not justified.
• Kettle-Type Reboilers — Enlarged-shell (TEMA K) reboilers for column bottoms and vaporising services that need disengagement space above the bundle.

Design codes (when specified)

• TEMA — Shell-and-tube mechanical design practice we can follow when the project requires it — a design standard, not a certification Ohm holds.
• ASME Section VIII Div. 1 — Pressure-part design basis we can follow when specified — not an ASME U-stamp or product certification claim.
• IS 2825 — Indian unfired pressure vessel code we can follow when named — design practice for that order, not a separate badge.
• HEI — Referenced for vacuum / condenser duties when specified.
• PED 2014/68/EU — EU installation pathway when contracted per project — not a default CE mark on every unit.

Materials listed

• Carbon steel
• Stainless steel (SS 304, SS 316, SS 316L)
• Duplex stainless steel (when specified)
• Other alloys as specified on the enquiry

RFQ data required

1. Duty (heat load) if known, or enough stream data to calculate it
2. Hot and cold fluid identities / services
3. Mass or volumetric flow rates
4. Inlet and outlet temperatures (both sides if available)
5. Operating and design pressures
6. Allowable pressure drop (shell and tube)
7. Fouling factors if specified by the process licensor or plant standard
8. Preferred materials of construction
9. Applicable design code (TEMA class, ASME, IS, or client spec)
10. Quantity, delivery location, and any drawing / P&ID / datasheet upload
