Detailed Product Description

The LAUDA Ultra range includes heating and cooling thermostats for the high-performance area in process engineering and measuring technology. Various bath sizes and temperatures up
to 400 ?C also fulfil special requirements. The Ultra-Kryomat series is the classic amongst the sophisticated chillers in the field of process engineering. Their compact design enables the
flexible lining-up of several test baths with various temperatures.

The special feature about the Ultra heating devices is that the control head is functionally separated from the thermostat. This offers the advantage of being able to control it remotely and guarantees maximum process safety. Alternatively, Ultra devices can come equipped with a duplex pump - a pressure/suction pump with constant level device for the thermostating of external open baths without the need for any additional equipment. The low-level and adjustable overtemperature protection features - which come as standard- further enable operation with flammable liquids (safety class III, FL). A cooling coil is fitted as standard. The USH 400 high-temperature thermostats are excellent for use in mini plants, reactors and applications in closed vents.
Fields of application: process engineering, industrial materials testing, quality control.

External control:
The connection of up to two temperature probes enables external control and temperature measurement directly on the object.

Highly-efficient automatic chillers and proportional cooling:
An energy-saving refrigeration technology is particularly important to process integration. Ultra-Kryomats automatically recognise when no cooling is necessary, and automatically switch the compressor off. The proportional cooling just cools as much as is necessary. This saves you up to 75 per cent energy. The temperature stability is excellent, room heating caused by waste heat is low. Even at the highest temperatures, you can rely on the cooling properties throughout the entire working range identical to the ACC range with LAUDA devices. Water-cooled refrigeration units have an economical through-flow control.

The power packs for demanding applications:
The powerful cooling unit extracts sufficient heat even at cryogenic temperatures of the bath liquid. Ultra-Kryomats are excellent for the materials testing of large-volume samples and for simulating space conditions in vacuum chambers.

If you need to provide thermostating up to 400 ?C in closed external circuits in the chemical industry, you will find technical perfection in the LAUDA USH 400 high-temperature thermostats. The specific characteristic is the two-chamber construction principle. In this case the thermostating chamber and the expansion vessel are thermally separated from each other.

LAUDA Ultra-Kryomats of the RUK series that work down to -50 ?C are compact, floor-standing cooling thermostats. They are characterised primarily by high cooling capacities and large baths. Multiple units can be arranged one after another for test baths with various temperatures.

The LAUDA Ultra-Kryomats of the RUL and RUK series are powerful all-rounders. In research and application technology they provide for low temperatures down to -80 or -90 ?C, with cooling capacities of 1 and 4 kW at 20 ?C, and thus give you an enormously wide application spectrum.

LAUDA Ultra control unit P: flexible programming for process engineering
LAUDA Ultra thermostats are equipped with a powerful control unit which provides numerous additional functions for ambitious applications in the process industry. In the Ultra heating thermostats the control unit is separated from the thermostat itself.
