PLASTIC PAD FOR EVAPORATIVE COOLING

LUBING GreenTec pads, which are made of polypropylene and much lighter, have a similar efficiency to paper pads with the difference that, over time, that of paper worsens while, thanks to the patented lattice, that of LUBING GreenTec pads improves due to the formation of deposits that increase their exchange surface area.

THE ADVANTAGES OF THE PLASTIC-PADS

For evaporative cooling of greenhouses.

Excellent cooling capacity – patented design: The
special layout of solid surfaces and mesh structures
ensures perfect water distribution all through the Pad. This allows perfect wetting, less splashing water, and therefore excellent cooling capacity.

Easy to clean: The use of welded, highly resistant
polymer sheets allows the Plastic-Pad to be cleaned
without difficulty and without damaging the Pads.

Long service life: The use of polymer sheets in combination with thermal welding guarantees best stability and a long service life.

Lowest pressure loss: The Plastic-Pad is characterized by low pressure loss. At an air velocity of 1,5 m/s the Plastic-Pad’s pressure drop is only at 10 Pa. Because of the low pressure drop the Plastic-Pad minimizes the energy consumption substantially.

High UV resistance: The use of UV-stabilizing additives ensures outstanding resistance to UV light for years.

Impermeable to light: The Plastic-Pad’s geometry
blocks out light.

Chemical resistance: The Plastic-Pad is made of Polypropylene. This material is highly resistant to most of all chemicals.

Advantages of plastic pads over paper pads

Plastic pads on the market are on average 30% less efficient than paper pads.

LUBING pads, which are made of polypropylene and much lighter, have similar efficiency to paper pads with the difference that, over time, that of paper worsens while, thanks to the patented lattice, that of LUBING pads improves due to the formation of deposits that increase their exchange surface area.

In addition, paper pads by retaining dirt create a bacterial load that produces mold, odor, contamination, worsening hygienic conditions.

Can plastic pads provide the same kind of cooling as paper panels?

Pad-Cooling systems are well known for greenhouse cooling and humidification, but plastic pads are relatively new.

The most frequently asked question is whether plastic pads can have the same cooling effect as traditional paper pads.

In short, the answer is yes. With Lubing GreenTec plastic pad you get the same cooling and moisture results as paper pads. The difference is that ventilation requires less energy, explains the Lubing team.

According to tests done in the field by the company, the special pad configuration (patented design) ensures ideal water distribution with less pressure drop than paper panels.

This allows for proper wetting and less water splashing, resulting in increased efficiency and cooling capacity, especially in hot climate regions.

The use of high-strength polymer sheets in combination with the innovative manufacturing process ensures perfect stability and long service life.

In addition, the plastic panels can be easily cleaned and restored with a pressure washer.

This considerably increases the service life compared to paper panels.

The use of stabilizing additives also ensures outstanding UV resistance for years.

Water quality requirements are very low.

Lubing GreenTec also offers a high-pressure Fogging-System for cooling and humidification of greenhouses.

The combination of the Pad-Cooling System and the Fogging-System can maximize the cooling capacity in very hot climatic regions.
