FAQ

PHE selection depends on five primary factors: process duty (heat load and temperatures), fluid properties (viscosity, fouling tendency, chemistry), design pressure and temperature, available pressure drop, and any hygienic, leak-detection, or material-compatibility requirements. Our engineering team can size a unit from your process data sheet. The more information you provide upfront, the more accurate the quotation.

At minimum: hot-side and cold-side fluids, mass or volumetric flow rates, inlet and outlet temperatures, design and operating pressures, allowable pressure drop, and material requirements. Additional useful information includes fouling factors, frame material preference, gasket adhesive type, and any code requirements (PED, ASME, ABS, etc.).

Yes. ARES PHE designs and manufactures custom heat exchangers across all product families: gasketed, brazed, welded, semi-welded, and shell & plate. Custom engineering includes special plate materials, non-standard frame configurations, exotic gasket compounds, and integrated skids. Our R&D team also supports OEM partners with bespoke plate geometries developed in-house.

Yes. Our application engineers use proprietary thermal-hydraulic software calibrated against AHRI-certified test data. We can also accommodate custom design constraints such as compact footprints, specific connection orientations, and integration with existing pipework. For self-service sizing, our online Selection Software is available.

Standard gasketed units typically ship within 4–6 weeks from order confirmation. Custom-engineered units, large frames, exotic materials, and certified marine units may require 8–12 weeks. Brazed plate heat exchangers are often available from stock for standard sizes. We confirm a firm delivery date with each quotation.

There is no minimum order for standard products; single units are routinely supplied for replacement and project applications. For OEM partners, volume agreements are available with preferential pricing and inventory management.

Yes. ARES PHE has an established OEM Supply programme that includes private-label branding, custom documentation, dedicated production scheduling, and confidentiality agreements. See our OEM Supply page or Distributor Programme for partnership enquiries.

Gasket service life depends heavily on operating temperature, pressure cycling, and chemistry. Typical intervals are 3–7 years for water-side service, 2–4 years for chemical or aggressive service, and 5–10 years for low-stress duties such as district energy. Our after-sales team can provide condition-based recommendations and supply genuine replacement gaskets sized to your exact unit.

Yes. Every ARES PHE unit is permanently archived with its full design data and bill of materials. Plates, gaskets, frames, and connections can be supplied for units manufactured at any point in our history. Provide your unit serial number for fastest service.

On-site commissioning, plate-pack inspection, gasket replacement, and performance verification services are available globally through our service network in Türkiye, the USA and China, plus authorised service partners in additional regions. See After-Sales & Service for full details.

Standard warranty is 12 months from commissioning or 18 months from shipment, whichever expires first. Extended warranty programmes are available for OEM partners and large project orders. Warranty covers manufacturing defects in materials and workmanship under normal operating conditions.

Yes. ARES PHE has subsidiaries in the USA (Arlington, TX) and China (Shanghai), plus an authorised distributor network across more than 50 countries. Contact our global network for the nearest service support.
