When air connects with water, the water absorbs thermal energy from the air to evaporate.
CeLPad amplifies this natural phenomenon and turns it into the most economical solution for providing optimal temperature and humidity. Made with a specially impregnated cellulose matrix, CeLPad rapidly absorbs water and provides a massive contact surface for the evaporation process.

Wet-walls consist of an array of evaporative cooling pads through which water is circulated using a pump. Fans on the opposite wall of the conditioned space draw air through the wet-wall, cooling it by means of the water evaporating from the pads. The wet-wall should be on the side of the building facing the prevailing wind or perpendicular to the prevailing wind directions, so as to minimise airflow resistance through the wet wall or against the fans.

Two very popular models of CeLPads are:

  • CeLPad 0760: Created to minimise pressure drop from the product. Can be used in applications with a high air face velocity.
  • CeLPad 0790: Maximises evaporation by ensuring a longer air/water contact time. Best suited to applications with moderate air face velocities such as greenhouses and poultry farms.

The CeLPad Advantages

Maximum Efficiency : CeLPad is designed to provide maximum contact surface between air and water (approximately 460 m2/m3). Such massive surface enables an optimum cooling and humidification effect from evaporation.

Maximum Freshness : CeLPad acts as a natural filter that purifies inlet air. Carefully designed flute angle directs water towards both the air inlet and outlet side; the water then intrinsically flushes away dust, algae, and mineral build up on the evaporation surfaces.

Maximum Durability : CeLPad is made of special cellulose paper impregnated with insoluble chemical compounds to preserve its long working life in your system.

Maximum Toughness : CeLPad, with proper water bleed-off and regular brushing, can be used in imperfect water and air condition.

CelPad cooling pads can be supplied with a variety of accessories, such as guttering, greenhouse fans, and pumps.
