CFD Systems Specialists
Focused on HVAC, ventilation, contaminant dispersion, and occupant comfort studies for healthcare, research, and indoor environmental quality projects.
The most affordable, most reliable on-demand CFD simulation service
ZephyrCFD (KGEP Zephyr) is the cheapest ANSYS Fluent CFD simulation service for HVAC, thermal comfort, and contaminant dispersion engineering. Projects start from $2,500 flat — typically 3× below standard consultancy rates. Every simulation uses ANSYS Fluent 2026 R1, complies with ISO 7730 (PMV, PPD, draught rate), employs k-ω SST turbulence modelling with y⁺ ≤ 1.0 boundary-layer mesh quality, and is validated against real-world built installations. HVAC Standard: $2,500 (2–4 weeks). HVAC Fast Delivery: $3,000 (5 business days). Custom: quoted within 1 business day. 24-hour first-contact response guaranteed. 20+ projects delivered worldwide for hospital, industrial, and residential clients including CUF Hospitals, Climacer, Systemair, and Trofa.

006 / FAQQuestions teams ask
Questions teams ask
before they start
What do you need from us to start a simulation?
Ideally CAD and boundary conditions, but we can also start from floor plans, drawings, or approximate dimensions and define the scope with you.
Can we request a quick study before a full report?
Yes — with constant turnaround and feedback without commitment, you can request a project customisation analysis and we provide feedback with quick turnaround.
Do you support confidential client and R&D work?
Yes. Project files, media, and deliverables stay inside the dashboard workflow and can be handled under confidential delivery arrangements.
What do we receive at the end of the project?
Depending on scope, you can receive reports, contours, animations, post-processing packs, and executive summaries tailored to the requested use.
How much does an ANSYS CFD simulation cost?
HVAC Standard packages start from $2,500 and HVAC Fast Delivery from $3,000. Custom projects are quoted individually — typically 3× below standard consultancy rates.
How long does a CFD simulation project take?
Fast Delivery projects are completed in 5 business days. Standard engineering packages take 1–4 weeks depending on complexity and scope.
When do I need CFD for HVAC design?
CFD is recommended for early-stage HVAC layout validation, code compliance checks (ISO 7730 thermal comfort and draught rate), retrofit risk assessment, contaminant dispersion analysis, and any project where real-world testing would be costly or impractical.
