INTEGRATED HYDRONIC UNIT (Optional).<br />
Compact PLUG <strong>and</strong> PLAY units.<br />
NECS has been designed to reduce installation work to a minimum.<br />
The integrated hydronic unit incorporates all the hydraulic components, thus optimising installation space,<br />
time <strong>and</strong> costs.<br />
The integrated hydronic unit comprises:<br />
• storage tank<br />
• circulation pump with composite impeller<br />
• pre-mounted Y-shaped <strong>water</strong> filter with stainless steel mesh<br />
• <strong>water</strong> flow switch<br />
• pump inlet pressure gauge<br />
• output flow adjustment valve<br />
• safety valve<br />
• expansion tank<br />
• <strong>air</strong> vent<br />
• <strong>water</strong> drain.<br />
A circulation pump with a two-pole electric motor <strong>and</strong> an elevated useful static head is available<br />
for all sizes.<br />
Pumps with a low useful static head <strong>and</strong> a 2- or 4-pole electric motor are available for units with four<br />
compressors (NECS xxx4) in order to more fully adapt the unit to system requirements in terms of flow<br />
rate/head. On request, the hydronic assembly can be supplied with two circulation <strong>pumps</strong>, one of which<br />
backing up the other, featuring a programmed rotation schedule <strong>and</strong> automatic swap-over should the<br />
working pump fail.<br />
In this case, the hydronic assembly is fitted with a check valve in order to ensure the unit is installed <strong>and</strong><br />
operated correctly.<br />
