Outstanding Strength Points
R410A Refrigerant.
New simpler refrigerant circuit layout.
Efficiency class B and C.
Low sound level for BLN unit, very low sound level for ELN unit.
Great accessibility to internal components for service operations.
New display on external panel allows the complete control of the unit.
More assembling quality.
Construction easier.
Operating limit of the unit stored in the flash memory of the control logic.
Wide operating limits.
High temperature operating limits.
Less noisy compared to the unit with R407C.
Less number of screws and piece of sheet metal.
Component standardization (symmetric sheet metal, only 2 kinds of screws …).
New gauge kit can be fitted directly inside the units and not outside. This gauge kit is cheaper than R407C one and it is common for the whole range.
Fan speed control for low ambient operation in cooling mode down to-18 °C.
Units are suitable for low water temperature applications with leaving water temperature of -8 °C (min).
ModBus interface.
Phase sequence monitor supplied as standard.
User-friendly microprocessor control.
ILTC (Intelligent Liquid Temperature Control) controller that allows to reduce the need of an external water tank.
Leaving water temperature control logic now available.
For safety during service operations, special valves dedicated to R410A are available on the refrigerant system. These valves, of 5/16” flare SAE type, are mounted on the liquid line inside and on the lateral panel of the unit. This facilitates the access to the high and low side of the refrigerant circuit in order to do pressure measurement.
Double water set point.
Rubber pad supplied as standard.
Water filter and flow switch supplied as standard.
Optional plug and play hydraulic kit for last minute configuration equipped
with 1 or 2 pump(s). Pumps can be supplied with or without buffer tank.
Optional electric heaters fitted inside buffer tank to ensure extra heating.
Double automatic air vent (only for unit with pumps).
Victaulic connection and Victaulic valves that allow fast connection.
Double 3/8” valve on water pipes for pressure measurement and water charge/discharge.
New anti-vibration kit, easier to be installed (same spring for every corner).
Special Inverter Fan (SIF) version suitable for a widening of operating conditions, like ducted installation where high static pressure is needed or high ambient air temperature installation. Fan speed will be regulated by condensing pressure.
Smaller footprint. The units are 100 mm thinner in order to simplify the transport operation.
Extra low noise version now available.
Desuperheater now available as option.
Smart hook in the electrical panel that keeps in position the closing panel while the operator is working on the electrical box.
Refrigerant circuit completely enclosed in a separated box in order to reduce the noise, not only of the compressors but also of the whole circuit.
