Efficiently irrigate, mist and humidify with Lechler nozzles

In summer months like these, when the sun sends its hot rays from the sky, one or the other sun-seeker may enjoy it - nevertheless, everyone is grateful for a wet cooling. Especially in agriculture, which has to struggle more and more with dry periods, but also in certain industrial areas that involve dusty or heat-intensive environmental conditions, irrigation, sprinkling or humidification with water is necessary or even vital.

Lechler Düsen für die Beregnung und Befeuchtung

Here, Lechler nozzles are the optimum solution for the agriculture as well as for various industrial sectors struggling with the above-mentioned problems. Used for specific applications, they enable efficient irrigation, mist application, moistening or particle binding.

Examples in Agriculture

Watering trolley for irrigation in greenhouses

In nurseries, "nurturing and caring" for crops from seed to ready-to-sell plant is a whole-year issue. But especially in the summer months, controlling the climate and water supply for the benefit of the plants is quite crucial. With so-called watering trolleys, the plants are often supplied with water very evenly several times a day and, if necessary, also with nutrients.

Depending on the size of the plant and the need for water, our customers use for this purpose


Cow Cooling – Avoiding heat stress in the cow shed

We humans experience "heat stress" at high summer temperatures and/or high humidity, which challenges our circulatory system. For cows as "suppliers" of milk, cream, yogurt, the level of heat stress is much lower than for us bipeds, because their metabolism is working hard to convert grass, grain or corn into milk. This generates a lot of heat, which cows can poorly dissipate through their skin (leather).

Cows feel comfortable at -5 to +20° C; above these temperatures stress begins for them and we can use Lechler nozzles to ensure that they are well - also in the interests of animal protection. The consequences of heat stress are less feed intake, less movement of the animals and also a lower production of milk, with higher costs for the farmer.

In addition to large fans to cool the animals, nozzles are also used to increase the cooling effect.

Cow shower – always cool cows

Cow showers – also called low-pressure systems – are optimally suited to lower the body temperature of the cows. It is important to ensure air movement through cross-ventilation in the shed or to install the showers outdoors, otherwise there is a risk of a "tropical climate" with very high humidity and additional stress. For a cow shower, coarse drops – similar to rain – are optimal because they reduce the increase in humidity and penetrate better into the cow's skin. By using a timer, a cow shower can be operated at intervals while reducing water consumption at the same time.

As a cow shower in aisles, in the waiting area or running yard we recommend

  • several full-cone nozzles of series 460 in polypropylene or
  • nozzles of series 490 in brass/stainless steel to shower several animals at the same time and avoid rank fights.

Cow soaking – cooling during feed consumption

Soaking – cooling during feed consumption

To cool cows specifically during feed consumption – so-called "soaking" – we recommend to cool above the feed fence and thus out of reach of the cows,

installed on the pipe at a distance of 1.5 – 2 m. With little pressure and coarse drops, we thus achieve cooling of the animals while eating. Ideally, fans support the cooling effect and a time control reduces water consumption.

Examples in General Industry

Tank sprinkling/spraying/cooling

Tank sprinkling/spraying/cooling and preventive fire protection

The purpose of tank sprinkling/spraying/cooling is to protect tanks or other containers from impermissible heating during a fire. For effective protection of a tank, it must be sprayed with water on all sides or covered with an even film of water. This also serves as preventive fire protection. Lechler offers nozzle solutions for optimum wetting of various types of containers of all sizes – whether upright/lying cylinder tanks, spherical containers or reaction towers.

Air humidification and cooling

Air humidification and cooling

From microelectronics to packaging, there are many industries where air humidity has a major impact on the quality of manufactured products. Nozzles are used for air cooling and humidification to increase the efficiency of heat exchangers, or the nozzles are installed in air conditioning systems for humidification and cooling. In addition, nozzle technology can be used, for example, to directly humidify the air in production halls or storage rooms.

Applicable nozzles:

Dust control

Dust control

In many areas of processing, dust generation and the associated stress for humans, animals and technology play a major role. For dust control, fine water droplets are used which bind airborne dust particles, thus giving them a higher weight and causing them to sink or stick. The size of the water droplets, which can be optimized by selecting the appropriate nozzle, is decisive for effective dust control with atomized water. It is also possible to reduce dust formation by moistening the material. Efficient, cost-effective solutions are required in sectors such as the automotive industry, the chemical industry, the food and beverage industry, the pharmaceutical and cosmetics industry, the pulp and paper industry, as well as in coal mining, stone quarries and waste disposal sites.

Applicable nozzles:

  • Low-pressure single-fluid nozzles (hollow cone nozzles and full cone nozzles)
  • High-pressure single-fluid nozzles
  • Pneumatic atomizing nozzles
