1 THE RANGE
The series MCC of the air cooled water chillers and heating pumps has
been designed for indoor installation, for residential and commercial
applications, when duct connection is required.
The series MCC has been designed and developed with the 410 A refrigerant,
in fact the unit reaches excellent level of energetic efficiency thanks to the
optimization of the heat exchangers in the type of plates and the distribution
of the refrigerant.
The logic of the Plug&Play on the hydraulic side- already present (DNA) in all
our water chillers models - here is going alongside with the Plug&Play on the
fans group : Auto - adaptive control of the air flow and the constant fan speed
modulations (condensation control on pressure basis) reduces the installation
costs and timing.
> PLUG&PLAY ON AIR SIDE:
Autoadatptive air flow depending on:
- pressure drop on air side
- inlet air temperature
All units comes with modulating continuous fan speed control that adjust
the rpm of the motor depending on the air temperature and air pressure drop,
using a cutting-phase device.
Air outlet can be vertical or horizzontal (optional).
> HYDRAULIC PLUG&PLAY
3 different hydraulic kits are available to enable an easy installation of MCC
units in the cooling and heating system:
- B version: standard unit with evaporator
- P version: unit with evaporator, pump and expansion vessel
- S version: unit with evaporator, pump, expansion vessel and water tank
> SIMPLIFIED MAINTENANCE
Centrifugal fans are directly coupled to the eletric motor without using pulley
and belt system.
The compressor and technical compartment is completly separated from
the fan compartment in order to perform check operation while the unit is
operating .
Easily accessible electronic microprocessor control.
> ELECTRONIC MICROPROCESSOR CONTRO PANEL
Brand new technology, it allows the connection with ERGO
Adjustable set-point thanks to an outdoor temperature probe (optional).
