Company-wide unit system (Metric ↔ Imperial). One switch flips flow, pressure, velocity and temperature across every preview and the datasheet PDF.

Pick which product tiles (AHU, FCU, Ventilux, Eakon, Cold Room, …) appear on your dashboard — a personal choice that follows your sign-in. Super-admins also set which products are available to everyone.

Standard AHU shell sizes (EAES5B-0402, -0403, …). Face W × H + base velocities used by the sizing picker.

Parametric fan part-drawings (DIDW / SISW / Plug). Edit the dimension table; the drawing auto-updates, then save per model number.

Filter cell catalog: type (G4, F7, HEPA), dimensions, clean & loaded ΔP. Bulk Excel upload supported.

Frame profiles, damper costs (Dampers-ECOAIR), door defaults (DoorDefauls-ECOAIR), and drive data (Drive-Data-ECOAIR) — four tabs inside.

Pre-built unit configurations (model + coil type + sections) for "Defined" mode — pick one instead of dragging components by hand.

Per-category drawing / visualizer / page-setup config (AHU · FAHU · FAHU-HRW · FAHU-HP-HRW · Ecology · FCU · Ventilux). Lets you tune the PDF and AHU viewer rendering without touching code.

Flow ↔ velocity table for the 592×592 and 592×292 standard cells used by the sizing picker.

Sand-trap louver sizing helper — pick a size by target face velocity.

36 bundled mini-labels (cold/hot × A+ → E × default/recirculated/standalone). Picked per-unit and embedded on the submittal preview + export.

DLL binaries used by the fan-selection workflow (Kruger fan curves, etc.). Upload, manage versions, download.

ECOAIR AeroClime Series rooftop package units (05CAT5-I … 30CAT5-I) — full engineering specs, electrical + fan + cooling performance matrices, and a selection / back-end calculation engine (airflow + ESP + ambient → fan duty + cooling capacity).

ECOAIR EACU air-cooled condensing-unit catalog: capacity (Ton / kW), refrigerant, compressor. Feeds the DX coil selector (single + multi-unit combinations to meet the coil load).

Reference port of COOLING COIL CALC..xlsx — Calculation, By-pass Factor, and Fin Efficiency intermediates. Same backend API the Cooling Parameters page uses; here for auditing the math chain or running the workbook standalone.

Same V_2.2 coil-calculation sheet pre-set to a direct-expansion (DX) coil, plus the shared design-limit catalogs (coil & circuit, row & FPI, fin spec, panel limits).

Library of water-circuit (coil circuiting) sheets keyed by ROWS × FPI. The Coil Drawing report embeds the matching sheet for the selected coil instead of the auto-generated serpentine.
