Software

Plate & Frame Heat Exchangers are the workhorse of process heat transfer — compact, fully serviceable, and efficient across an enormous range of duties, from HVAC and district heating to chemical process cooling. Because the plate pack can be opened, reconfigured, and re-gasketed, they remain the default choice wherever maintainability matters as much as thermal performance.

N-PHE software sizes and rates these units from first-principles thermal-hydraulic calculations, not correlations borrowed from tube or shell exchangers. It calculates plate count, corrugation angle and chevron pattern effects, port sizing, pressure drop on both sides, and overall effectiveness — the same variables a plate manufacturer's own selection software would check, run independently so you're not relying on a vendor's own numbers to validate a vendor's own quote.

The edge is transparency. Every intermediate result — film coefficients, fouling margins, pressure drop breakdown — is visible and exportable, so an engineer can defend the design in a review instead of citing a black-box output. That matters most when a client, auditor, or EPC contractor asks 'how did you get this number,' and the honest answer needs to be more than 'the software said so.'

Typical inputs take under five minutes to enter — hot and cold side flow rates, temperatures, allowable pressure drop, and fluid properties — and the tool returns a complete plate specification along with a full performance summary, ready to hand to a fabricator or attach directly to a design package.

Welded Bloc exchangers trade gasket serviceability for chemical resistance and pressure capability — a fully welded plate pack built for aggressive or high-pressure duties that standard gasketed plate units simply cannot handle safely.

N-BLOC software calculates thermal performance and mechanical limits specific to welded-block construction, including the structural considerations that come with eliminating gaskets entirely — weld joint stress, differential thermal expansion across the block, and pressure containment margins appropriate to fully welded construction rather than gasketed assembly.

The edge: because these units serve the toughest applications — corrosive process fluids, high-pressure services, duties where a gasket failure would be a genuine safety incident — our calculations build in the safety margins that generic plate-exchanger tools don't account for, rather than treating a welded bloc as just a plate exchanger without gaskets.

Output includes material compatibility flags for common corrosive services — acids, chlorides, and other aggressive process fluids — so a design that looks acceptable on thermal performance alone doesn't get flagged later in a materials review after the order is placed.

Type 2 spiral configurations extend the spiral exchanger's self-cleaning advantage to a different flow arrangement — typically used where Type 1's configuration doesn't suit the specific combination of duty, space constraint, or flow pattern involved.

N-SPHE2 software calculates performance for this configuration specifically, rather than forcing a Type 1 approximation onto a Type 2 duty and hoping the difference doesn't matter. It handles the distinct flow path and channel arrangement Type 2 uses, producing sizing results that reflect the actual equipment configuration rather than a generalized spiral estimate.

The edge: knowing which spiral configuration genuinely fits your process is half the engineering problem, and getting it wrong means a unit that's technically a spiral exchanger but doesn't deliver the performance profile your duty needs. Our tool helps confirm the right configuration before you commit to fabrication, not after.

Where the choice between Type 1 and Type 2 isn't obvious from the duty alone, the tool flags the tradeoff explicitly — projected performance and footprint for both configurations — so you can make an informed choice rather than defaulting to whichever one you specified last time.

Shell and Tube exchangers remain the industry standard for good reason — proven over a century of use, robust in operation, and adaptable to nearly any process duty, fluid, pressure, or temperature range you'll encounter.

N-ST software handles the full sizing and rating calculation: tube count and layout, baffle spacing and cut, shell-side and tube-side pressure drop, and configuration checks against TEMA standard classes so the design you produce is one a fabricator will actually recognize and quote correctly.

The edge: shell and tube design has decades of established correlations behind it, and our tool applies them with genuine rigor rather than a simplified approximation — so results hold up against both engineering theory and long-established industry practice, which matters when the design goes in front of a client's own review engineer.

Output includes a full TEMA-format datasheet, ready to issue for fabrication quotes — tube layout drawing data, baffle configuration, nozzle sizing, and a complete thermal and mechanical performance summary in the format fabricators expect to receive.

Feed Water Heaters improve boiler and power cycle efficiency by preheating feedwater using extracted or waste steam — a well-established, high-value efficiency measure in any steam cycle, but one that depends entirely on correct sizing to deliver its promised gain.

N-FWH software calculates thermal performance, tube bundle sizing, and drain cooling zone design specific to feedwater heating service — including the condensing and subcooling zones that distinguish a proper feedwater heater from a generic shell-and-tube exchanger pressed into the same role.

The edge: feedwater heaters have design considerations most generic heat exchanger tools don't account for — deaerating requirements, drain cooling zone sizing, and integration constraints with the broader steam cycle. Our tool is built around feedwater heating specifically, not adapted from a general-purpose exchanger calculation.

The tool models the full three-zone design where applicable — desuperheating, condensing, and drain cooling — since treating a feedwater heater as a single-zone exchanger is a common simplification that produces an optimistic and ultimately inaccurate performance estimate.

Dry Coolers reject heat to ambient air without consuming water — an increasingly important option wherever water use is restricted, costly, or simply unavailable in the quantities a wet cooling tower would require.

N-DC software calculates finned-tube performance, fan sizing, and sensitivity to ambient design conditions specific to dry cooling duty — accounting for the way dry cooler performance shifts with ambient temperature far more dramatically than water-cooled equipment does.

The edge: dry cooler performance is highly sensitive to ambient temperature swings across the year, and sizing against a single fixed design-day assumption is a common source of summer performance shortfalls. Our tool accounts for real seasonal variation at your site, not just a textbook worst-case number.

The tool runs performance checks across a full seasonal temperature range rather than a single design point, flagging any month where predicted performance falls short of duty requirements — the same gap that, left unchecked, tends to surface as a real operational problem the first hot summer after installation.
