VARIO PRESS 330.eZR

The all-in-one among pressing furnaces – VARIO PRESS 330.eZR with TTC.

The VARIO PRESS 330.eZR is the full equipment package: firing furnace, pressing furnace and TTC cooling technology in one device – for laboratories that want to run everything from lithium disilicate pressings to zirconia veneering from a single chamber.

ADVANCED PRESS™ (patented): In the standard pressing process, there is around 40 °C between the furnace temperature and the investment ring core – the result is pronounced reaction layers, rough surfaces (“orange peel”) and laborious finishing. ADVANCED PRESS™ keeps the difference at a maximum of 4 °C: all objects are pressed in the ideal temperature window for lithium disilicate regardless of their position – for smooth, homogeneous surfaces, minimal reaction layer and extremely short pressing times.

TTC mode: Software and lift technology enable linear cooling at a freely selectable cooling rate after firing – stress cracks and the dreaded chipping are a thing of the past. This is the decisive quality factor, especially for veneers on zirconia frameworks.

Dynamic pressing pressure control: The electronics recognise the required forces based on the geometry of the pressing objects and automatically adjust the pressure throughout the entire process – defects caused by prematurely terminated pressings are virtually eliminated.

Z-Drying mode: A virtual sensor continuously calculates the lift position from the firing chamber temperature and keeps the pre-drying temperature at the object constant – preventing cracks and bubbles, and considerably faster than manual pre-drying.

Safety: The Power-Fail-Control (PFC) properly completes the programme at the correct point after brief power interruptions. Via the USB port and the Zubler Download Center you can, after registering the device, load firing programmes for all common dental ceramics as well as software updates – including an extended warranty.

Those who can do without linear cooling will find the more affordable sister model in the VARIO PRESS 330.e. Accessories: firing base and P3 vacuum pump. Dentoo delivers your Zubler furnace ready for operation: advice on the right version, delivery, instruction and support from a single source – Made in Germany from Ulm, with short routes for service and spare parts.
