Suchoběžné šroubové vývěvy ULVAC série LS

ULVAC LS series dry-running screw vacuum pumps

ULVAC LS is an innovative dry-running screw vacuum pump that features a pair of conically shaped steel screws with variable pitch, which allows for pumping even near atmospheric pressure. The vacuum pump is up to 1/3 lighter than a conventional screw vacuum pump and is designed primarily for clean applications. However, it can also serve as a vacuum pre-pump.

It is available in 4 models with pumping speeds of 120 to 1,200 m³/h.

Key benefits of the LS series include:

noise level below 61 dB (A)
light weight and smaller dimensions
high pumping speed near atmospheric pressure drastically reduces pumping time.
integrated built-in shock absorber of the ECO-SHOCK technology
low power consumption

Use for clean processes (type "C"):

pumping air or nitrogen.
load-lock chambers
lamination
vacuum steaming
vacuum sputtering

Use for light processes (type "L"):

pumping steam and heavy gases
general industrial processes
laboratory applications
freezing
vacuum drying

Suchoběžné šroubové vývěvy ULVAC série CR

ULVAC dry-running screw vacuum pumps of the CR series

ULVAC CR are air-cooled, dry-running vacuum pumps designed for clean and wet processes. The devices can extract up to 500 g/h of steam (or pure gas). These properties make them suitable as a vacuum source for vacuum dryers, sputtering equipment and evaporation systems.

Key benefits of the CR Series include:

compact design
air cooling
low operating cost
light weight
integrated silencer

Applications and use in real life:

steam pumping
pumping of pure gases
vacuum drying equipment

vacuum coating equipment
vacuum sputtering
rotary evaporators

Suchoběžné šroubové vývěvy ULVAC série LR/HR/UR

ULVAC dry-running screw vacuum pumps of the LR/HR/UR series

The ULVAC LR/HR and UR series vacuum pumps are specially designed dry-running vacuum pumps for applications where heated vacuum or exhaust piping is required. For this capability, it is suitable for PVD processes and CVD coating. They can also serve as support vacuum pumps for turbo and mechanical booster vacuum pumps.

Key benefits of the LR/HR/UR series include:

high degree of surface hardness
excellent corrosion resistance
excellent helium pumping ability
enclosed electric motor
easy maintenance
withstands power interruptions for up to 500 ms

Applications and use in real life:

PVD etching processes (LR series)
CVD dry etching processes (HR series)
Bridgman method

heat treatment processes
processing of procedural gases

Zařízení pro úsporu energie ULVAC ECO-SHOCK

ULVAC ECO-SHOCK energy-saving device

ECO-SHOCK is an accessory for dry-running vacuum pumps for the ULVAC LR / HR / UR models. The device can reduce energy consumption by up to 80%. It supports pumping of air, nitrogen and inert gases, such as argon. It connects to the exhaust pipes.

Key benefits of this accessory include:

up to 80% reduction in energy consumption of the dry-running vacuum pumps
no reduction in the working performance of the vacuum pump
easy installation
