SKH4 - Atomizing High Pressure Humidifier

ABOUT

SKH4 - Atomizing High Pressure Humidifier

High humidification at low power

The SKH4 pumps water at high pressure of 1,000 psi (70 bar) through a series of nozzles to produce a fine mist. The adiabatic evaporation used by the SKH4 takes energy (heat) from the surrounding air to evaporate the fine mist (water droplets). This evaporative cooling / humidification process provides large output capacities of 210- 2,800 lb/h (100-1,250 kg/h), that can be modulated with a high turndown ratio of 20 lb/h (10 kg/h).

The power consumption is very low for the high load of humidification produced, compared with isothermal technologies or even other adiabatic technologies such as compressed air. The range of motor from 1/2 to 5HP (0.4 kW to 3.7 kW) is able to generate high cost savings on the humidification process and also on the cooling load of a space.

The SKH4’s controller can be configured with either temperature control for a cooling application or humidity control for humidification. It allows you to temper industrial and commercial indoor areas where heat build-ups could be unfavourable to occupants, production, and material goods.

Distribution can be from nozzle placed directly in space or inside a duct, for added precision. Fan-assisted distributors can help with the efficiency and homogeneity of the distribution of the cooled humid air.
