Dimensions

Hexamotion units are available in 5 different regulation programmes, all available with right or left access depending on airflow direction.

Season 

Designed for temperate climate zones, Season Hexamotion provides air renewal with efficient energy recovery, summer/winter operating of the rotary heat exchanger wheel and adjustable flow rates by potentiometer.

First

Self-regulation unit for temperate climates, with active temperature management for optimal energy consumption and thermal comfort.

Premium Co

FIRST features, but also equipped with a changeover water coil for low outdoor temperatures down to -20°C.

Premium DXR

FIRST features also with a changeover R410A coil for low outdoor temperatures down to -20°C.

Premium BE

FIRST features and also equipped with an electric heater for low outdoor temperatures down to -20°C.

Controllability

Hexamotion has 6 choices of flow rate modulation for optimised energy consumption

SEASON

Adjustment of each fan rotation speed by potentiometers mounted and connected in the control system board.

For versions FIRST and PREMIUM, the EASY regulation can control the fans in the following modes:

Eco

Fans speed adjustment via 2 airflow settings (LS-HS) in the EASY regulation.

Lobby®

Airflow rate modulation with CONSTANT PRESSURE mode, adjustable for each fan.

Diva®

Proportional modulation of each fan airflow depending on the CO2 rate. Sensor integrated in the exhaust air inlet.

Mac2®

Modulation in constant airflow for each fan (LS and HS) (except sizes 05 and 08). Pressure transmitters integrated inside the unit.

Quattro®

Proportional modulation in constant airflow for each fan depending on the CO₂ rate (except sizes 05 and 08). Pressure transmitters and CO2 sensor (exhaust air inlet) integrated in the unit. Setting of the LS, the HS and the CO2 minimum rate (ppm) adjustable on site directly on the easy regulation.

LCD controller functions:

• Airflow
• Temperature control
• Timer commissioning
• Battery
• Night over ventilation
• Local controls
• Default readings

Filtration

Hexamotion units as standard include highly efficient F7 opacimetric filters for both the fresh air and exhaust air. Filters are mounted on slides for easy replacement and are fitted with draught-proof sealing ensuring efficient airtightness. Additional filters for the supply air are an optional extra.

Construction

• Constructed of 10/10^e outdoor panels
• Insulated with 50mm high density M0 A1 mineral wool
• External panels are painted with RAL 7035 with a protective film
• Internal panels constructed of galvanised steel
• Circular connectors with lip seals for airtightness guarantee
• Access by doors mounted on hinges for easy maintenance

Heat Exchanger

Caladair Hexamotion units feature highly efficiency aluminium rotary heat exchanger. The heat exchanger is situated in a rigid frame mounted on a slide rack for easy removal and maintenance.

The heat exchanger provides heat recovery efficiency high than 80%. It has a variable speed that enables improvement especially during midseason.

Motors

Hexamotion units are equipped with low energy consumption motors, each unit features 2 EC motors.

Installation

Hexamotion units can be installed both indoors or outdoors. Hexamotion units have a compact design with a small footprint. Duct connections are situated on the side of the unit with double lip circular connectors for an airtight, quick and cost-effective installation with no adapters required.

Top panel integrating a rooftop for indoor and outdoor installation as standard.

Insulation of Ductwork

We recommend you use Metal Spiral ducting and fittings due to superior strength.

To provide the best performance in airtightness and durability we recommend You provide greater mechanical strength to a joint by using self-sealing fittings or a combination of Ducting Sealant and Aluminium Duct Sealing Tape.

1. Apply Duct Sealant to the male fitting
2. Push together
3. Apply Aluminium Duct Sealing Tape over joint

It is important that any ducting located in a cold area (e.g. loft space) to be insulated. The insulation needs to be the equivalent of 25mm thick and have a thermal conductivity of 0.04W/(m.k) or less.

This ensures that condensation doesn’t form due to the difference in air temperature inside the duct when compared to the air temperature in the cold space.

If you don’t have a loft space there is still a need for insulated ducting on the intake and exhaust legs, as they will be carrying cold air in a warm space. The level of insulation can be achieved by wrapping PVC duct in a layer of 25mm duct wrap that has a silver foil face on a 25mm rockwool

It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations.

Accessories

Hexamotion models are compatible with a range of ducting systems. A full range of controls, sensors, silencers and valves/diffusers are also available to complete installation of your ventilation system.
