Technical Data
General Description
CHV2 units generate an airflow with “Coanda” effect due to particular air handling section. The unit is suitable for
installation in a suspended ceiling. Air intake is from the bottom while the air supply is parallel to the ceiling through
practical and functional intake and outlet grilles. The “Coanda” effect creates excellent circulation of air inside the room.
A condensate pump is supplied as standard part.
Construction
Cases are constructed of galvanized sheet steel with integral fan mounting rails for added strength. Fire resistant
insulation is fitted internally and externally provide both thermal and acoustic insulation.
Round diffuser
The Coanda unit is supplied with round diffusers suitably designed to generate an air flow with “Coanda” effect. The
direction of diffuser air flow can be adjusted on site.
Chilled water coil
Constructed with seamless copper tubes and headers. The tubes are mechanically expanded into corrugated aluminum
fin material for a permanent primary to secondary surface bond. Coils are tested at 35 bar and recommended for
operation at 20 bar. Coils include manual air vent and water purge.
Fan
The backward-curved centrifugal fan is statically and dynamically balanced for quiet operation. Fan impellers are made
from fire-retardant plastic for lightweight and corrosion-resistant operation.
EC motor
The unit is using EC motor include driven controls PCB, a constant torque, permanent magnet, brushless EC motor with
preliminary 3-speed setting that allow for precise air balancing.
Condensate pump
A condensate pump is fitted to carry water out of the unit. The pump can be withdrawn from the side casing by removing
screws. A float switch is fitted to stop the cooling action, should the pump become blocked or fail.
Fresh air
The fresh air system for CHV2 unit allows up to 15% of unit airflow (maximum air flow per connection is 100m
3
/h) as
fresh air intake (per connection). Maximum 2 fresh air connections per unit are allowed.
Filtration
The standard filter is easily removable, is washable and is made from self-extinguishing acrylic with an efficiency of class
G2 (EU2).
Intelligent control (I type)
Intelligent control board is controlled via Infra-red handset and/or Intelligent wired wall pad, is field programmable and
easy to be configured through the wired wall pad or open Modbus protocol with VWV and VAV control logics, provides
variable speed indoor fan control, integrates with Intelligent modulating valves to allow Auto Dynamic Balancing and
Intelligent Constant Delta T management systems. It controls 2-pipe, 2-pipe with electric heater, 2-pipe with 6-way
valve and 4-pipe systems.
Flexible control (W type)
This control options features flexible functionality for external thermostat applications, allowing the independent
control of drain pumps (if equipped), offering zone control operations, and limited diagnostics. In products where
louvers are required, this control allows the stepping motors to open the louver at maximum position or close them
when power of the unit is OFF.
