DABV in hotels and commercial buildings
DABV is a passive technology mounted externally on existing piping. No chemicals, no energy input, no consumables. In operation across hotels, commercial buildings, agriculture and food production in Northern Europe and the United States.
Benefits
One coupled phenomenon, three expressions.
Mineralisation, biofilm and microbubbles are not three separate problems that occur simultaneously. They are one coupled phenomenon with three expressions. DABV is mounted externally on the pipe surface and operates alongside existing filtration, softening, UV disinfection and chemical dosing.
ENERGY REDUCTION
Lower your
operating cost
Biofilm and mineral deposits insulate heat exchange surfaces and reduce energy efficiency. DABV mobilizes accumulated deposits, which the system carries away through normal operation.
10–20% average reduction in water-related energy consumption
WATER QUALITY
Suspended solids drop
without chemicals
Baseline suspended solids in circuit water ranged from 30 to 50 mg/L. After installation, solids spiked during the cleaning phase as accumulated deposits mobilised, then settled below 5 mg/L through the stabilisation period. The reduction was achieved without inhibitors, biocides or dispersants.
From 30-50 mg/L to below 5 mg/L suspended solids.
PATHOGEN REDUCTION
Lab-documented reduction in
P. aeruginosa
An independent study by Nofima AS in 2024 documented a 90% reduction in Pseudomonas aeruginosa, a chlorination-resistant biofilm pathogen, after 24 hours of treatment.
90% reduction in biofilm and pathogens (e.g., E. coli)
PASSIVE OPERATION
Continuous
passive operation
DABV operates without electricity, chemicals or consumables. Mounted externally on the pipe surface, the device runs continuously. The host water system's existing service schedule is unchanged.
30% REDUCTION IN CHEMICAL DOSING
Three cost lines hidden inside hydronic systems.
Energy costs keep rising.
Untreated systems lose 15%-25% of design efficiency over fifteen years. Deposits accumulate on heat exchanger surfaces from the day a system is commissioned, and the energy penalty is continuous.
Kemikaalit lisäävät kustannuksia ja monimutkaisuutta
Inhibitors, biocides and dispersants appear monthly in the operating budget. Around them sit SDS handling, spill containment and contractor access, all part of the compliance load.
Operational downtime is costly
Hot water interruptions, chiller faults, and unplanned plant-room work during occupied hours carry costs no single line item captures. In a hotel, the cost lands in guest complaints, comp nights, and review scores. In commercial property, in tenant SLA exposure.
sustainability
Energy reduction reports through the meters the property already submits.
The same meter and BMS data the property already submits show the energy reduction. The corresponding CO₂ reduction follows from the emission factors the property already uses.
DABV works within existing systems.
DABV is mounted externally on existing piping. The host system requires no retrofit, no new infrastructure and no change to operating routines. The unit operates passively from installation onward.
No power, no chemicals, no consumables.
The unit is a passive component on the supply line. It draws no power, adds nothing to the water and contains no parts that wear or expire.
External installation on existing piping.
Installation takes place on the outside surface of the existing pipe. The pipe is not cut, drained or modified. The host system continues to operate during fitting.
Passive component.
The unit is a passive component, on the same maintenance principle as a check valve or a strainer body: no moving parts, no power input, no consumables. Service intervals are set by the host system, not by the device.
