JetSprayCompressed air and water spray humidifier

JetSpray panelAn IP54 rated cabinet with easilyaccessible internal components to controlthe operation of the nozzles. All electronicelements are housed in a separatecompartment above the water and air pipes.

Power supplySingle phase power, 230V/50Hz or110V/60Hz, max 210W powerconsumption (excluding air compressor).

Remote user interfaceBacklit digital multilingual display withkeypad giving control and information on operation, commissioning, servicerequirements and fault diagnostics. Canbe located up to 100m from the JetSpraypanel. The system can also be controlledvia BMS.

Compressed air supplyEnsures rapid moisture evaporation,highly directional sprays with no risk ofdrips. The JetSpray uses at least 30% lesscompressed air than any other air andwater atomising humidifier.

Water supplyThe JetSpray can operate on any potablewater quality without the need for ademineralised supply, minimising waterconsumption.

Self-cleaning nozzlesPrecision engineered nozzles with a 10-year warranty offer long life, minimalmaintenance and are intrinsically safewith no local electrical supply required.

Humidity sensorA single in-room humidistat or up tothree averaging sensors can be used tomonitor room conditions and provideaccurate humidity control.

DrainAutomated drain and purge cyclesensures water cannot stagnate in thesystem. Air run-on leaves waterpipework dry when no humidity isrequired.

PureFlo Ag+ silver ion water treatmentSilver is a powerful bacteriostatic agentwith residual effects throughout the pipework, promoting hygienicoperation. UV water treatment is alsoavailable as an option.

The combination of compressed air andwater allows the JetSpray to providerapid moisture evaporation without the risk of wetting or drips.

The JetSpray is available in 60L/h and 600L/h capacity models. The600L/h model is available with on/offcontrol or fully modulating 0-100%output for highly accurate +/-2%RH humidity control.

Self-cleaning nozzles enable thehumidifier to work with any potablewater quality without the need for ademineralised supply. Its fan-freedesign ensures robust operation indirty, dusty industrial environmentswith minimal maintenance.

Why use compressed air?A compressed air and water humidifieroffers guaranteed evaporation of themoisture into the atmosphere withoutany potential risk of drips. By forcingthe water to mix with the air underpressure, the sprays produced arerapidly absorbed and highly directional.

This makes the JetSpray ideal for coldtemperature applications, such as coldstores, where the ambient humidity isoften high and moisture less readilyabsorbed by the air.

As no fan unit is required to encourageevaporation, the JetSpray can reliablybe used in very dusty and dirtyindustrial environments withoutfrequent maintenance.

Low maintenanceThe JetSpray nozzle contains a self-cleaning mechanism that preventsblockages. A pin is forced through thenozzle orifice whenever the spray stopsand is pushed back by the waterpressure during operation. Unlikepiston driven nozzle systems nolubrication of this mechanism is everrequired and the only necessarymaintenance of the nozzle line is tooccasionally wipe the air caps toremove dust.

The nozzles are so robust in operationthey carry a 10-year warranty.

Easy to installThe JetSpray humidifier can beinstalled by any competent mechanicalcontractor. It incorporates standardplumbing fittings and pipework, anddoesn’t need any special tools forinstallation. The system can besupplied with stainless steel, copper orplastic pipework.

Consistent and accurate humidity controlUnlike spot humidifiers that deliverhigh humidification outputs to thelocal area and rely on air movement todisperse the humidity, the JetSprayintroduces moisture evenly across aroom. The nozzles are strategicallypositioned to consistently spread thehumidification with no areas of high orlow humidity.

A fully modulating JetSpray provides0-100% output enabling the humidifierto maintain more accurate humiditycontrol than on/off systems at±2%RH.

Hygienic operationThe JetSpray is a sealed system with no open water tanks, minimising therisk of water contamination. Automaticpurge and flush cycles ensure watercannot remain in the pipelines to stagnate. An air run-on featureleaves the pipework dry at the end ofthe cycle.

PureFlo Ag+ silver ion water treatmentis incorporated on the incoming water supply line. This is abacteriostatic agent with residualeffects throughout the pipework,promoting hygienic operation.

50% less water consumptionThe JetSpray can be operated on anytype of potable water supply. Thisreduces water consumption by up to50% compared to other sprayhumidifiers that need demineralised orsoftened water to prevent blockages atthe nozzle.

30% less air consumptionUnlike other air and water sprayhumidifiers, which use the air pressureto push back the self-cleaning pinmechanism, the JetSpray nozzle usesthe water pressure. This results in alower required air pressure and a 30%reduction in compressed airconsumption compared to other airand water systems.

Low energy and evaporative coolingIn comparison with electric steamhumidifiers, the JetSpray consumes90% less electrical energy to deliver thesame amount of humidification. Ratherthan an electric heat source, thethermal energy of the air is used toevaporate the moisture. As well ashumidification, this causes an adiabaticcooling effect. For every kg ofhumidification, approximately 630W ofadiabatic cooling is also delivered,which can be a welcome benefit in ahot manufacturing environment.
