KaDeck

2-pipe system

With this design, the entire heat exchanger surface is available for temperature control, depending on the medium currently present in the pipe system (cold or hot water). Switch-over between heating and cooling takes place centrally via the building management system. This variant is particularly suitable for applications with seasonal switch-over and reduced installation effort.

4-pipe system

This version is suitable for sophisticated air conditioning concepts in which each room zone or unit can be switched over individually between heating and cooling. By routing the heating and cooling medium separately, the system offers maximum flexibility and comfort - ideal for buildings with changing usage requirements.

Both versions are based on the same high-quality basic design and differ only in the equipment for condensate treatment.

Variant for dry cooling: for operation above the dew point. It does not contain a condensate tray or pump and must not be operated with flow temperatures that cause the temperature to fall below the dew point.

Variant for humid cooling: for operation with cooling media below the dew point. It has an integrated condensate tray and a condensate pump to reliably collect and remove any condensate.

Two variants enable optimum integration into different ceiling systems. For installation in suspended grid ceilings, we offer:

• one version for grid dimension 625 × 625 mm
• one version for grid dimension 600 × 600 mm

The selection of the appropriate unit design depends largely on the existing ceiling system. The device drawings provide information on the number of grid fields required.

The single-sided version is particularly suitable for installation along room edges or in peripheral areas. It offers a compact solution for smaller zones or asymmetrical room layouts.

The two-sided version is designed for central ceiling-mounted installation and has two tangential fans. This achieves a higher air output, which has a positive effect on the cooling and heat output. This variant is particularly suitable for larger rooms or uniform air distribution.

When making the selection, particular attention should be paid to areas where people are present and the air flow in the room.

We offer various solutions for the control and regulation of our units, which can be used depending on the application and requirements:

Electromechanical control

This variant is ideal for simple applications. All integrated actuators are factory-wired to terminals and can be connected to our electromechanical accessories such as thermostats or external controllers.

KaControl MC1

Our comprehensive comfort control offers extended control options for individual rooms or appliance groups. It can be operated either via a touch display or a web interface. Thanks to on-site 0-10 V control or common communication protocols such as Modbus RTU & TCP, BACnet and KNX, this solution is ideal for all BMS applications.

• Mounting height max. 3 m
• Mounting height min. 2 m
• Wall distance min. 2 m
• Device distance min. 4 m
• If possible, stagger the units at least 1 m apart

Avoid the following:

• Impairment of free air circulation due to e.g. lamps, furniture or shelves
• Obstruction of air intake and air distribution
• Electronic units below the unit
• Inaccessibility for maintenance work

Example: KaDeck with two-sided air outlet

at 7/12/27°C 48%rh:

• 2 V - 0.7 m
• 4 V - 1.8 m
• 6 V - 2.8 m
• 8 V - 3.8 m
• 10 V - 4.2 m

Coanda effect:

• Utilization of the Coanda effect through horizontal air distribution for a high throw
• Slow and comfortable lowering of the conditioned air into the room

• Service hatches are not necessary for both closed ceilings and system ceilings.
• Accessibility of all maintenance-relevant components through the appliance cover.

Mounting the units:

• Integration into a 625 x 625 mm or 600 x 600 mm system ceiling
• Can be installed freely suspended, suspended ceiling frame optional
• Suspended ceiling frame available for flush ceiling connection and freely suspended
• Further information on the suspended ceiling frame in the accessories

When operating the unit below the dew point, note the following:

• The maximum delivery height of the condensate pump is 6 m and must not be exceeded.
• Condensate lines must be ventilated or vented.
• Provide lines with a permanent and continuous gradient (1%). Avoid inclines or so-called "water pockets". Use only fixed lines (no flexible hoses) for horizontal lines.
• Connections and transitions (e.g. from hose to fixed line) must be tightly and mechanically secured, e.g. by the use of hose clamps.
• If a siphon stop device is located at the transition point from the device to the on-site drain, it must be mounted at the highest point of the drainage profile.
• Protect condensate-carrying lines against falling below the dew point, e.g. by means of vapour diffusion-tight insulation.

• Connection of centrally processed primary air to the device possible
• permissible air temperature 14 - 25 °C
• Primary air spigot available as an optional accessory
• Connection diameter 80 mm
• 1-sided devices: 60 m³/h
• Double-sided devices: 120 m³/h (max. two nozzles, max. 60 m³/h per nozzle)
