For
users who require very high levels of purity from their recirculating water,
ATC can offer an in-line deioniser, with all necessary fittings, mounted to
the rear of the chiller. This will polish the recirculating water to better
than 1 to 10 Siemens/cm. Cartridge expiry indication is by means of colour
change windows (blue - ok, brown - replace). A by-pass flow system is
included to ensure that the flow rate through the cartridge is always
optimal.
