SKH4 - Overview

Overview

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 the motor from 1/2 to 5HP (0.4 kW to 3.7 kW) can generate high-cost savings on the humidification process and 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 takes place from the nozzles which are 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.

Stainless Steel panel
Nema 4 Type panel in stainless steel to house control connections for valves and fan-assisted distributors.

Configurable number of valves for each application Remote Valve Panel (RVP) can be configured with only drain valves, to be placed at the end of a long run network, avoiding the return piping distributors.

Distribution Manifold Branch out the stages from the RVP to a far away zone to limit pressure losses created by multiple long runs from the pump unit.

Fan assisted control point Dedicated connection point to control the activation of the fan-assisted distributors.

In-Space (Direct)

An array of nozzles on a high-pressure piping network creates a series of mist cones. The network then sprays in the space, starting from the pump unit or with the help of remote valve panel (RVP). The configuration of the in-space network is flexible, it can start from the pump or with remote valve panel added.

Advantages of In-Space Nozzle Rack:

  • The SKH4 misting nozzles can cover a large area, usually hanging from
  • Multiple installation options to fit every space
  • Cost effective solution ideal for large spaces with high ceilings (30ft / 9m)

In-Space Radial spray (MDU)

Radial projection mist distributor uses an axial fan to help with absorption distances and homogeneity of the air in a room. Installed through suspension ropes from the ceiling, the MDU has a low footprint and helps cover a large area uniformly..

Advantages of the SKH4’s MDU:

  • High output
  • High coverage
  • Reduce absorption distance and improves air mix

The SKH4 MDU (Mist Distribution Unit) is a fan assisted distributor that will spread mist radially. Ideal for large space with low ceiling (15-20ft / 4.5-6m).
