ECODRY plus - Dry multistage roots vacuum pumps
Designed for quiet and clean environments
The ECODRY plus is a family of dry-compressing multi-stage roots vacuum pumps, setting new standards in terms of:
- Compact size
- Light weighted
- Low power consumption
- Long service intervals (maintenance-free for five years)
- No particle generation
- Low noise level in its class: specially designed for use in quiet and clean environments, such as analysis and research laboratories.
The multi-voltage, high-speed, contact-free pumps with peak pumping speeds from 25 up to 55 m3/h have been specially designed for use in applications requiring short pump down times, low noise, low vibration, and no particulate generation such as analytical instruments, research laboratories and light industrial processes.
ECODRY plus: let your applications benefit from the oil-free pump design!
Maintenance free for years of smooth operation
ECODRY plus features a friction-free operating principle, so their components are not exposed to wear in any way.
All ECODRY plus are designed for up to five years’ operation. Maintenance measures such replacing seals or changing the oil are not required during that time.
In the case of the pump itself, this guarantees long-term stable operation with no deterioration in final pressure or suction capacity.
Small, light and easy to handle
The ECODRY plus dry vacuum pumps have a compact housing and are simple to operate.
- With integrated castors and low weight, they can be easily positioned and moved around at any point in time.
- There is no need for complex installation work: the pumps can be connected directly to a single-phase electricity supply.
- The pumps are air-cooled, and therefore require no connection to a water supply for cooling purpose.
They will easily fit into any size laboratory. There are no wearing parts or particle generation, so it can be used in laboratories requiring very clean environments.
Fast pumps with quiet operation
With high speed from high pressures down to ultimate vacuum your vacuum system pump-down times are significantly shortened.
The low ultimate pressure of down to 0.01 mbar makes the ECODRY plus ideal for backing turbomolecular pumps and cryopumps in Ultra High Vacuum (UHV) applications.
The rotors’ high manufacturing quality guarantees that the pumps will run with a low level of vibration. Consequently, also with a low level of noise, even at high inlet pressures. Efficient noise insulation is integrated within the pump housing, to shield the user from residual noise. The silencer integrated within the exhaust further serves to minimize noise, even at high gas flow rates.
Combining these features achieves a low noise level of less than 52 dB(A) - meaning they are quieter than a normal conversation.
Clean and environmentally friendly
Thanks to the oil-free pumping chamber, no lubricant can enter the vacuum chamber or the environment of the pump.
Furthermore, because the rotors operate contact-free, no abrasion debris is created in the form of particles, which could contaminate the vacuum chamber.
Clean vacuum generation with no contamination of workstation or vacuum chamber.
High water vapor tolerance: no internal condensation
In drying applications, such as cryopump regeneration, or when pumping out vacuum chambers with large surface areas, high quantities of water vapor may accrue.
Not every pump can handle this without difficulty, as condensation in the pump can lead to corrosion and pump failure.
With its gas ballast valve open, the ECODRY plus can pump water vapor at rates of up to 500 g/h without internal condensation.
Integrated control dashboard for an intuitive operation
The ECODRY plus enables intuitive operation thanks to its integrated control dashboard.
It offers you the possibility to directly connect both vacuum gauges and valves to the pump: enabling easy pressure and valve control, resulting in improved energy efficiency and process safety.
The intelligent pump controller enables easy operation. A wide range switchable power supply (100 to 240 VAC, +/- 10%) makes these pumps suitable for consistent operation in all parts of the world.
Multistage roots working principle
These vacuum pumps are based on the multi-stage roots pumping principle with two rotors turning in opposite directions in a single pump housing. The rotors do not get into contact with one another, or with the pump housing making them both quiet and clean pumps.
Through their rotation, they convey the gas from the intake flange on the upper side to the outlet aperture on the bottom of the pumping chamber. Several pumping stages are arranged in series to achieve a high compression ratio.
The pump’s operating range extends from the medium vacuum range to ambient pressure. Short channels between the compression stages, combined with a very high rotational speed, enable a compact package with high pumping performance. The pumping chamber is oil-free allowing clean vacuum generation.
