Using the DVX-138
What the rating means
DVX-138 is rated at 138 l/day, which is about 5.8 kg/h. Working figures of that kind are useful in two directions: they convert a moisture load into a model, and they show how much water the drain has to carry away on a wet day.
Catalogue capacity is quoted at a defined test condition, and the accepted figure for an order is the one on the approved drawing. Warmer, wetter entering air gives the coil more water to remove per cubic metre; cooler or drier air gives less. Any model quoted for a project is checked against that condition rather than the headline number.
Installation and air path
Outdoor air enters one collar, is treated, and leaves through the other as supply. Because the unit sees the whole ventilation load, duct static, filter pressure drop and the condition of the outdoor air belong in the selection, not only the volume of the room behind it.
On this frame, the fan moves 1200 m³/h, the cabinet measures 1000 × 650 × 410 mm, rated noise is < 45 dB(A).
What to send with an enquiry
- Room volume or air-change rate, with the height the air actually occupies.
- Entering air temperature and relative humidity in the worst week of the year.
- The band that has to be held, and the tolerance the process really needs.
- Fresh-air volume and its condition, where the room is ventilated.
- Internal moisture: people, wash-down, open tanks, wet product coming in.
- Drain route and the power available at the mounting position.
With those answers the model is checked against the moisture load. If the frame is wrong for the room, the reply names the platform that fits instead of pushing this one.
Where this model stops
Where outdoor air sits below the published working range for long periods, the coil spends its time in defrost and the ventilation load goes unmet. Those projects are quoted with a rotor platform or a preheat section instead.
Drawings, electrical data and the installation manual are released with the order, so the site works from the document that matches the frame delivered.
Questions about the DVX-138
How much room can the DVX-138 dry?
DVX-138 is rated at 138 l/day, moving 1200 m³/h. Room size on its own does not settle the model: the load is the air-change rate multiplied by the moisture difference between outdoor air and the band you need, plus whatever the process adds. Send the volume, the air-change rate and the target band and the same calculation comes back with the model and the figure behind it.
How is the DVX-138 installed?
Outdoor air enters one collar and leaves the other as treated supply, so the DVX-138 sits on the fresh-air duct rather than inside the room. Filter pressure drop and duct static belong in the selection, because the unit sees the whole ventilation load.
What power supply does the DVX-138 need?
The published supply is 220 V / 50 Hz. Cable size and protection follow the installed configuration, so the circuit at the mounting position is checked against the approved drawing rather than against the catalogue page.
How cold can the DVX-138 work?
Below that range a condensing coil frosts, defrost cycles take back running time and useful output falls away, so colder rooms are quoted on a desiccant rotor platform instead.
Is the 138 l/day figure guaranteed on site?
The figure is quoted at a defined test condition. Warmer, wetter entering air gives the coil more water to remove per cubic metre; cooler or drier air gives less. For an order the condition and the required removal rate are written on the approved drawing, which takes precedence over the catalogue figure. Enquiries are answered within one business day.
