Compare the four systems
Specs only, no ranking. The four series do different jobs: the first table shows which jobs each one does, the second lists the published figures, and the four steps narrow it down before a survey.

What each system does
Read the rows, not the columns: the question is which jobs your space needs.

Technical data
Published figures, side by side
Each column is one datasheet at its stated test conditions. Rows without a published figure are marked, not guessed.

How to choose
Four questions that narrow it down
The same questions our engineer asks on the first call.
- 01
Is the space sealed or ventilated?
A villa with a working fresh-air supply usually needs Series R to dry the air it already has. A sealed, double-glazed apartment or villa has no way to get fresh air in without letting humidity in, so Series F or Series T is the starting point.

- 02
How large is the moisture load?
Occupancy, showers and kitchens, pools, loading doors and stored goods set the load, not the floor area. Homes and hotel rooms sit within Series R and F. Warehouses, pool halls, showrooms and server rooms move to Series H.

- 03
Does the space need outdoor air?
If fresh air is required for occupants or by code, choose between Series F (fresh air, exhaust and energy recovery in one unit) and Series T (fresh-air treatment with its own exhaust path, no heat-recovery core). Series V provides balanced ventilation without dehumidification.

- 04
Is the problem dust, not humidity?
If readings are already in range but dust and allergens are the complaint, Series A at the AC return filters the whole return-air flow. Every dehumidifying system also carries three filter stages, so filtration is never an add-on.

Two units that complete the range
Series V is a balanced energy-recovery ventilator for new builds and renovations; it does not dehumidify and pairs with Series R. Series A is an electrostatic purifier at the AC return for dust and allergens, not humidity.
Questions about choosing
Short answers; the survey settles the rest.
Which system suits a villa?
Most villas with a working fresh-air supply start with Series R, one unit per zone or floor, sized to the moisture load. A sealed villa, or one where the owners want filtered fresh air, moves to Series F or a combination of Series R and Series T. The survey decides.
Which system suits a sealed high-rise apartment?
Double-glazed apartments trap moisture from showers, cooking and laundry and have no clean way to bring fresh air in. Series F brings in filtered, dried outdoor air, exhausts stale air and recovers energy from the exhaust. Where only humidity control is needed and ventilation exists, Series R is the simpler choice.
Can systems be combined?
Yes. A common pairing is Series R for the recirculated air with Series T or Series V for the fresh air, each on its own ducts. Large buildings often use several Series H units by zone. One controller per unit; integration with a building management system is reviewed per project.
Is there a system that only ventilates or only filters?
Yes. Series V ventilates with energy recovery and does not dehumidify. Series A filters the AC return air electrostatically and does not dehumidify. Both are listed under the four main systems.
Which system is the cheapest?
Prices are on request and quoted after a survey, so no system is ranked here. In general the installed cost rises with capacity, with the number of duct connections and with the length of the duct and drain runs.
