High Quality ECONET Manufactured by Manor Manor Econet | Page 2

Non metallic mesh provides an effective coverage area for an efficient evaporation surface with
minimal air pressure drop Meshes are fixed in front of the heat rejection surface via spacer bars
and/or fixing brackets to suit the unit configuration. Various size sectional mesh panels are
either joined together to form a full mesh area or alternatively flexible mesh roll cut to fit to a
required size in front of the heat rejection surface. This design provides easy maintenance and
replacement for the mesh panels.
Fixing Brackets:
Custom made brackets are designed to match any coil configuration they can be hooked from
the coil tubes in the coil and mesh area. Spray nozzles are also fitted as part of the bracket
arrangement.
Controller:
A custom made intelligent PLC based controller records the ambient conditions and at a pre set
value, which is adjustable by the operator, initiates in-line solenoid valves(s)
Water is sprayed intermittently to wet the meshes. The spray rate and duration are adjusted by
the controller to suit the ambient conditions, hence minimal water consumption. Water usage is
based on total waste principal, hence, no health risk.
ECONET controller is provided with internal override terminals for a volt free input which
overrides the temperature set limit and initiate intermittent spray as soon as this terminal is
linked. This facility can be used to provide head pressure or manual remote override flexibility
ECONET Performance Data:
Water spray durations and frequencies are constantly adjusted by the ECONET intelligent
controller in order to optimize the performance as well as minimize water consumption. The
higher the ambient temperature longer the spray and the frequency of the spray is also
increased to match the ambient conditions. Once the low ambient set point is reached the spray
operation is automatically terminated.
