SOLUTIONS

Industrial electrical heaters

Joule-heating packages integrating thermal duty, heating elements, power control, process containment and safety protection.

Typical engineering scope

Thermal-duty and heat-flux definition
Element and pressure-boundary design
On/off, thyristor or mixed power control
Temperature monitoring and protective trips
Panel, cabling and hazardous-area interfaces
Factory testing, commissioning and training support

ENGINEERING DELIVERY FRAMEWORK

From a defined duty to an operable handover

Each package is treated as an integrated system—not a collection of isolated equipment. Process, mechanical and control decisions remain connected through traceable, reviewable deliverables.

Design basis & simulation

Freeze the design basis, operating cases, feed composition, normal and turndown capacity, ambient conditions and battery limits before detailed engineering. Mass-and-energy balances, equipment sizing and hydraulics are developed from verified inputs.

Process safety & operability

Review PFDs and P&IDs; support HAZID and HAZOP; define cause-and-effect, ESD and blowdown requirements, maintainability access and control philosophy to reduce commissioning and operating risk.

Multidiscipline engineering control

Coordinate process, mechanical, piping, structural, electrical and instrumentation deliverables through a document register, interface control, comment resolution and disciplined change tracking through final and as-built issue.

Technical procurement & fabrication

Prepare datasheets and material requisitions, evaluate bids, review vendor documents, define ITP hold and witness points, control materials, inspect fabrication and track NCRs to closure.

Commissioning readiness

Define mechanical completion, pre-commissioning check sheets, test packs, cleaning and leak testing, loop and logic verification, start-up support and performance testing.

Lifecycle handover

Compile the manufacturing data record, operating and maintenance manuals, recommended spares, lessons learned and a traceable handover dossier for the operator.

Technical Datasheet

Technical Datasheet — Industrial electrical heaters

These published examples cover distinct electric-heater families and one application case. Do not combine their pressure, temperature and power endpoints as one heater rating.

Published values apply only to the cited equipment family and stated scope; they are not universal code limits or a Delham rating/guarantee.
Parameter	Published value	Reference basis	Applicability / limit
Dry-gas heater module power	12–31.2 kW	Published power range for one indirect electric dry-gas-seal heater family.	Specific to that module family; multiple modules may be connected for greater duty.
Dry-gas module design envelope	−50 to 300 °C; up to 6,800 psi	Published design-temperature range and standard-offering pressure capability for the same sealed-gas product family.	Model-specific design values; confirm pressure-boundary code, process conditions, element compatibility and relief design.
High-temperature gas/liquid exchanger example	Up to 650 °C	Published maximum design temperature for a separate electric heat-exchanger product family.	Official product-page and specification-sheet pressure figures conflict (300 vs 3,000 psi); no pressure rating is asserted pending confirmation of the current model/revision.
Single process application rating	101 kW; outlet 340 °C at 450 psig	Published methane/hydrogen preheating case study for a particular heater system.	One duty point, not a standard range; gas composition, flow, temperature rise and allowable pressure drop must be re-sized.
