Leybold NOVADRY : Vacuum as a key technology
The demands placed by manufacturers and consumers on the quality , shelf life and resource efficiency of food and packaging processes are constantly increasing . This applies even more to such perishable products as for example meat or fish . Vacuum is considered as an enabling technology , contributing significantly to optimizing these processes . Therefore , Leybold developed the innovative NOVADRY , a new 100 % oil free , air-cooled pump , as a solution to support customers .
NO OIL , LESS EFFORT Many users in meat processing and packaging cannot actually tolerate vacuum pumps emitting oil , and NOVADRY prevents such contamination . That is why Leybold designed a 100 % dry pump following hygienic criteria . This increases safety in applications such as tumbling , filling , vacuum packaging and thermoforming . An additional advantage of oil-free vacuum pumps is the lower cost of ownership , as less maintenance and spare part changes are required .
AIR COOLING REDUCES TOTAL COST OF OWNERSHIP Normally , dry pumps are water-cooled , but the NOVADRY is air-cooled . This reduces operating costs by simplifying the installation and commissioning . The total life cycle operational costs of the
NOVADRY are lower than for oil-sealed vacuum pumps , this was a key driver during the pump development .
BROAD RANGE OF APPLICATIONS The NOVADRY also stands out due to its long uptime and robustness . Some competitor products lose their endpressure or reduce pumping-speed due to wear of the inner coating , for example . The NOVADRY , however , achieves its performance over the entire pressure range and life cycle . This makes it ideal for simple applications , which emit low amounts of humidity , such as packaging of cold products . Moreover , the pump is also perfectly suited for more demanding processes with large amounts of water vapour , for example when hot meals with temperatures of up to 95 ° C have to be quickly cooled down by evaporative cooling .
PROVEN IN REAL LIFE NOVADRY has successfully passed many qualifying field endurance tests in a wide range of food applications – tumbling , tray sealing and thermoforming . In all applications , it shows very good performance , the users reached fastest cycle times and low final pressure
FORWARD-LOOKING PUMP At Leybold we have succeeded in developing a forward-looking product which has the potential to set a new standard for the food processing and packaging markets . This is due not only to the absence of oil , but also to the NOVADRY ’ s noise behaviour , the robust design and the low life-time costs .
