Heating and cooling with low temperature and heat pump

For large rooms with plenty of floor space, the Ultra is ideal. Its design makes it particularly suitable for heating in low temperature operation. In combination with a KaClima heat pump, it creates a future-proof, energy-efficient system – a simple solution for removing heating and cooling loads.

Targeted air direction control

With its hexagonal shape, the Ultra features a 6-sided air outlet that enables optimal horizontal air distribution. The direction can be adjusted in 6 ways using louvres.

Model sizes

The unit is available in four sizes.

Mounting options

The Ultra ensures optimal air distribution even at low room heights between 2.3 m and 4 m without drafts.

Timeless design

The Ultra has become synonymous with efficient and responsive air conditioning in retail markets. Its hexagonal casing is its hallmark. 

Easy Maintenance

Maintenance of the Ultra is extremely simple. The bottom cover can be easily removed for cleaning the externally mounted pump sump and float switch.

Technical highlights

With primary air supply

  • Supply of primary air in conjunction with a central ventilation system is possible via an optional supply air spigot that can be connected to a round pipe.

Energy-efficient EC fan

  • Infinitely variable EC motor of the fan operates particularly energy-efficiently and extremely quietly.
  • Exactly the required output is delivered, with not a watt too much and not a decibel more than necessary.
  • The fan complies with the ErP requirements.

Integrated motor full protection

  • The „intelligent“ motor electronics detect any motor fault that may occur and automatically switch off the fan.
  • This fault can be evaluated externally.

High output with compact dimensions

  • Thanks to the heat exchanger with a large surface area, the Ultra achieves both high heating outputs in low temperature operation at low heating medium temperatures and maximum cooling outputs.
  • The special heat exchanger also enables a particularly low installation height. This allows the Ultra to be installed in a space-saving manner below an open or suspended ceiling.

Control options

KaControl MC

With the integrated KaControl MC control, the Ultra offers bidirectional communication of up to 10 units within a group/room via CAN bus. With KaControl MC, the unit can be easily integrated into common building management systems such as Modbus RTU, Modbus TCP, BACnet/IP and KNX-TP. 

Electromechanical control

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