WDP100-AL
Water Distribution System

Munters WDP100-A: Water Distribution System

The WDP100-AL water distribution system from Munters provides highly durable means of mounting 100 mm thick CELdek® evaporative cooling pads and supplying water to the pads. Together these form an ideal complete system for incorporating evaporative cooling into the ventilation system of a structure.

Corrosion of metal parts is a frequent problem amongst gutters used to mount evaporative cooling pads. This leads to frequent leaks and a short life expectancy on such systems. Additionally a lot of time can be wasted on maintenance by trying to keep the system functional. In order to reduce the time and money spent on such unnecessary activities and increase the life expectancy of such a system, all the parts of the WDP100-AL system are manufactured in either extruded aluminium or plastic, which provides for an extremely durable system.

The main structural components of the system are the top and bottom extruded aluminium gutters. They have the dual purpose of holding the pads as well as distributing the water. A perforated water distribution pipe with a unique self cleaning shape is incorporated into the top gutter. This allows for the even distribution of water onto the top of the pads, eliminating dry streaks in the pads. In such dry streaks no evaporative cooling can take place and consequently hot dry air can enter the structure through such spaces even while the system is in operation. The extruded aluminium channels are very sturdy which allows for a longer distance between mounting brackets.

An incorporated distribution pipe; a clean smooth aluminium finish and a long distance between mounting brackets all ensure a neat finish as well as quick and easy installation.

Watering kits provide all the necessary pipe work and fittings, the tank and pump required to complete an installation. The only external connection that has to be supplied is for connecting the supply water line to the ball valve in the tank. Plumbing kits are sized to ensure the right pump capacity and tank size is used for each length of installation.

Installation options

The WDP100-AL can be mounted in different configurations. Below are the possibilities with the maximum length of gutter, each watering kit and drain kit can service.
