Ultra

The units are available in "heating only" or "heating and cooling" versions.

Both versions are based on the same high-quality basic design, but differ in terms of their equipment.

Units for heating and cooling have a condensate tray and a condensate pump to collect and remove any condensate. The heat exchangers are optimized for cooling operation.

The units are available in several model sizes to allow the performance to be tailored to requirements. The model size is selected depending on the required thermal output, the air volume flow and the sound requirements of the room. Larger model sizes offer higher performance, but are associated with larger housing dimensions, which must be taken into account when planning the installation situation.

Depending on the application area and application, variants with different heat exchanger areas and numbers of pipe rows are available. Units with a reduced heat exchanger surface area enable particularly high air volume flows and a deep air supply into large rooms. For demanding heating tasks, especially in the (operated) at low temperature range, we recommend versions with an increased heat exchanger capacity and several rows of pipes. These achieve a high heat output even at low flow temperatures and are ideal for modern, energy-efficient heating systems.

Unit heaters are available in two fan versions, each with a different maximum speed.

Variant with low speed

This version offers a limited maximum speed, which enables finer control of the air output. At the same time, the maximum sound power is reduced - ideal for applications with high comfort requirements in terms of sound.

Variant with high speed

A version with a higher maximum speed is available for power-intensive applications. It enables a significantly increased air output and is particularly suitable for industrial environments in which the noise level plays a subordinate role.

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.

• The unit heaters should be arranged symmetrically in the room to ensure an even flow through the room.
• Structural conditions such as lintels, ceiling cranes or other installations must be taken into account.

• The maximum mounting height Hmax is 4,5 m.
• Throw distances of 7.5 m are achievable.
• Structural conditions and design parameters can influence the mounting height and throw distances.

• The air is blown evenly into the room via six outlet panels.
• The louvers can be adjusted via a ratchet mechanism for air steering control.

• The Ultra is suspended using threaded rods or wire ropes.
• Four brackets for suspension are mounted on the top of the device.
• On-site, the fastening is carried out using suitable mounting material on the ceiling (e.g. on the raw concrete ceiling).

• The Ultra packaging includes a drilling template to easily transfer the suspension points.

• The condensate tray and heat exchanger can be serviced from the underside of the unit.

• The Ultra is connected to the building's pipework on the water side via a 1" thread.
• The connection area is printed to scale on the packaging.

• The maximum delivery height of the condensate pump is 6 m and must not be exceeded.

• An ISO Coarse 45% (G3) filter is available as an accessory.
• The filter can be retrofitted and easily removed from the Ultra for cleaning purposes.
