2. DESCRIPTION OF VERSIONS AND ACCESSORIES
VERSIONS
The available versions are:
i-32V5C Midi - standard version chiller
i-32V5C-DS Midi - chiller with desuperheater
The unit with desuperheater includes the addion of a brazed plate type heat exchanger made of AISI 316 stainless steel, factory insulated using
closed cell material. This version allows to recover about 20% of the condensing heat otherwise lost and to use it to feed the aer-heang water
coils of an AHU or for a hot water ywheel or for any other process use.
i-32V5C-BT Midi - BT version chiller (for low water temperatures)
The BT version unit allows the operang range of the unit to be extended by cooling water to -8°C. In this case, a mixture of water and glycol is
used.
