WVA-MH — front view with control panel, handle, and compressor socket

Insulation Drying

DÖLCO WVA-MH

Fully automatic water separator with integrated HEPA H13 — pump and filter in one M-module, with automatic compressor control

The WVA-MH combines a water separator and HEPA H13 filter in a single module — you save the separate microfilter device and reduce the system by one component. Plus an integrated compressor control: the compressor runs directly via the WVA-MH and receives its cycle automatically. The compressor (e.g., RT-M) is connected directly to the **blue 230 V socket** of the WVA-MH. The device thus takes over the automatic control of the entire drying cycle: the compressor generates vacuum and sucks standing water from the insulation layer into the tank; at a defined level, the control switches off the compressor and starts pumping; after approx. one minute, the compressor starts again. Without personnel on site, fully automatic — the drying process runs day and night. A central safety function: a **float switch** monitors the water level in addition to the pump. Should the condensate pump fail, the float switch automatically switches off the compressor — no overflow, no water damage due to defective technology. In the acrylic glass inner lid, you can see at any time during drying whether water is being transported out of the insulation layer. The integrated HEPA H13 filter simultaneously ensures that the extracted air is cleaned of dirt particles, bacteria, and fine dust — important in inhabited rooms and sensitive environments. The powder-coated aluminum housing is robust and easy to transport at only 17 kg; the foldable handle and the recessed cable compartment make mobile use comfortable.
