2.2 HE2 Overview
The HE2 system consists of two main components as follows:
– Evaporative Module
The evaporative module is available in a range of widths. Standard
width; (600mm (24”) to 3000mm (118”)) and XL width; (3300mm (130")
to 3900mm (153.5")). The module is also available in a range of
heights; (750mm (30”) - 3000mm (118”)) to match the requirements of
individual applications. The evaporative matrix consists of modular
cassettes with low pressure drop which are available in a range of
sizes and efficiencies.
The evaporative module is constructed from recyclable high grade
stainless steel.
The module has drain and overflow connections which are integrated
on HE2 MC3 versions. The drain assemblies supplied with HE2 XL and
HE2 MC3 systems are reversible and simplify drain plumbing.
A single electrical junction box, with pre-wired flying lead for connec-
tion to the management system is included in the HE2 MC3 system to
simplify installation. The HE2 MC3 Plus system has two electrical junc-
tion boxes with pre-wired flying leads.
Water flow and level in the HE2 MC3 systems are controlled by a fill control solenoid, float valve (x 2 on
HE2 MC3 or HE2 MC3 Plus XL) and low/high level float switch. Drain flow is controlled by a motorised
valve on MC3 systems. Water is recirculated over the matrix by a high grade circulating pump.
– Management system
The HE2 MC3 or HE2 MC3 Plus systems include a microprocessor
control panel which is located outside the AHU, up to 100m (328’)
away from the evaporative module. A 10m (33’) flying lead is supplied
unless otherwise specified (two flying leads are supplied on a HE2
MC3 Plus system). The system gives digital control over desired rela-
tive humidity or temperature levels, with a built in hygiene measures
such as; dilution, drain and other water quality maintenance features.
The system can be timer controlled to activate only during hours of
building occupancy.
Comprehensive real-time feedback shows current relative humidity
and temperature, demand, hours run, system operating status and
whether maintenance is required.
The whole system is easy to set up, has multi-lingual options (English,
French, German, Spanish, Czech, Dutch, and Swedish) and is secu-
rity code protected to prevent unauthorised alteration of system set-
tings.
