JetSpray

In-room compressed air humidifier

The combination of compressed air and water allows the JetSpray to provide rapid moisture evaporation without any risk of wetting. Its fully modulating output offers very accurate humidity control at ±2%RH.

The JetSpray’s fan-free, robust design and self-cleaning nozzles make it ideal for dusty industrial settings. It works effectively with mains or demineralised water and in cold temperature areas.

Hygienic by design

Routine flush and drain cycles ensure water cannot remain in the system to stagnate. An air run-on feature leaves the pipework dry when no humidity is required to protect against microbial growth in residual water.

An antibacterial filter treats the incoming water for added protection. This bacteriostatic system provides a lasting cleansing effect throughout the humidifier. An optional ultra-violet water steriliser can also be incorporated on the incoming water supply to inactivate pathogens and viruses.

Low water consumption

As the JetSpray can operate on potable mains water, it does not need a demineralised water supply to prevent nozzle blockages. This eliminates the wastewater sent to drain from RO water treatment systems and can reduce the overall water consumption of the humidification system by up to 50%.

Self-cleaning nozzles

The JetSpray nozzle uses a self-cleaning pin that prevents blockages by moving through the orifice after each spray cycle. As it is pushed back by the water pressure during operation, it requires no lubrication, unlike piston-driven systems. The nozzles are so robust in operation they carry a 10-year warranty.

JetSpray panel

An IP54-rated cabinet provides convenient access to nozzle controls, with all electronics stored separately above the water and air pipes.

Self-cleaning nozzles

Precision engineered nozzles with a 10-year warranty offer long life, minimal maintenance and are intrinsically safe with no local electrical supply required.

Humidity sensor

A single in-room humidistat or up to three averaging sensors can be used to monitor room conditions and provide accurate humidity control.

Remote user interface

The backlit digital display with keypad offers control, operational details, commissioning, alerts and fault diagnostics. Can be located up to 100m away and controllable via BMS.

Water supply

The JetSpray can operate on any potable water quality without the need for a demineralised supply, minimising water consumption.

Antibacterial water filter

Silver is a powerful bacteriostatic agent with residual effects throughout the pipework, promoting hygienic operation. UV water treatment is also available as an option.

Ultraviolet water treatment

Optional ultraviolet water steriliser can be incorporated on to the incoming water supply line to inactivate pathogens and viruses.

Compressed air supply

Ensures rapid moisture evaporation, highly directional sprays with no risk of drips. The JetSpray uses at least 30% less compressed air than any other similar system.

Drain

Automated drain and purge cycles ensure water cannot stagnate in the system. Air run-on leaves water pipework dry when no humidity is required.

When paper loses moisture, ink will not adhere properly, which could cause a problem for our printing company whose reputation for quality is high. Not only has the JetSpray been proven in our industry, it is also uncomplicated, energy efficient and extremely hygienic in operation.

Due to the conditions in our print room, the humidifier has been running 99% of the day since installation, keeping RH at a perfect 50%.

Darshananand Holdings Pvt Ltd (Bajrang Tea Factory)Aditya AgarwalDirector

“Before we had the JetSpray humidifier, we were unable to achieve the high humidity levels we needed. Our previous humidification system also tended to cause wet patches on the floor nearby. However, since we had the JetSpray humidifier installed, the area is consistently at 95%RH and we’ve managed to virtually eliminate weight loss from the tea during fermentation. This means the moisture stays in the leaf, improving the tea’s fermentation and enhancing the quality of our finished product. We’ve found the JetSpray humidifier very easy to operate and the use of compressed air in the aerosol ensures we never get any drips from the nozzles or wetting on the floor."

Parmeshwari Tea CompanyAjay DhandhariaManaging Partner

"After installing the JetSpray system we observed that any level of humidity required is constantly achievable without condensation or water getting deposited on the floor or over the machine. With improved humidity conditions, teas became brighter, blacker with better bloom and improved density."
