Hygrova
Hygrova is air-handling unit (AHU) design and psychrometric calculation software from Hathigen. Every number shows its formula, inputs and reference, with mass and energy balance checks at every stage and an interactive psychrometric chart. It also writes the control sequence and a PLC programme (Structured Text), shows the unit as a schematic and a 3D model, and handles multi-AHU projects with VAV and part load. It runs offline on Windows.

Our apps are code-signed, so Windows names the publisher as Hathigen Technologies. The certificate is new, so for a short while Windows may still say “Windows protected your PC”. If it does, click More info, check the publisher is Hathigen Technologies, then Run anyway. On company PCs, your IT team may need to allow it.

Everything you need, nothing you don’t.
Click-to-trace calculations
Click any number to see its formula, the values substituted in, the assumptions and the reference, then walk back to the raw inputs. Mass and energy balances are checked at every stage.
Interactive psychrometric chart
See every state point and process line plotted live as you change the design, in SI or IP units.
Control logic and PLC programme
A recommended control strategy for the train: sequence of operation, control modes with their thresholds, an I/O schedule, logic diagrams and a PLC programme in Structured Text.
3D model and schematic
A cut-away schematic and a 3D model of the unit. Air colour follows the calculated temperature, condensate appears only when water is removed, and heaters glow with their duty.
Multi-AHU projects, VAV and part load
One project holds every AHU in the building, with an AHU schedule, plant totals and diversity. Variable-air-volume units are also designed at minimum flow.
Envelope sweep and verification
Sweep a range of outdoor and room conditions, size each component at its governing case, then check supplier capacities against it.
Quick calculators
Twelve site checks on the same validated property functions: air state from any two properties, airflow volume to mass, humidity-sensor cross-check and more.
Sample projects
Ready-made projects to learn from: office floor with VAV, operating theatre, pharmacy dry store, cleanroom ISO 7, a whole hospital block and extreme climates.
Complete component library
Mixing, filtration, heat recovery, cooling and dehumidification, desiccant wheels, heating, humidification, fans, ducts and room loads.
Four steps, start to finish.
Define
Set the site, airflow, ranges and room loads.
Build
Assemble the AHU, or let Hygrova propose the train.
Check
States, balances, envelope and supplier data.
Hand over
Spec sheets, control logic, PLC programme and a PDF report.
