Dehumidifying dryer for optical resins that condenses high performance,
contamination-free drying into a compact frame
- Adds contamination prevention to the DEZAT NR-3 dryer
for specializing in optical components molding
- Applicable with optical products molding machines up to 80 tf class (NX-5)
- Heatless dry air unit that delivers cryogenic dehumidification
at –50˚C and maintenance-free operation
- Round System for high efficiency drying and airtight structure
to prevent outside air penetration
■ Round System
As with the NR-3, STOLZ’s Round System has been adopted to supply and circulate dehumidifying air of –50˚C generated by a heatless dry air unit through a closed system.
■ Applicable with N2 gas circulation
An N2 gas connection port (ø6 mm) comes as part of the standard equipment for introducing N2 gas. (N2 gas cannot be circulated at the same time as dry air from the heatless dryer unit.)
■ Closed conveying system
The closed conveying system transfers plastic to the molding machine over an airtight circuit using suction force. Because secondary air is not drawn into the circuit, it shuts out moisture found in the surrounding environment, thus enabling thorough drying.
■ High clean factor, contamination-free
Contamination-free drying for maintaining clean room cleanliness is provided via a 3 µm fine-mesh filter element, clean blower and high performance line filter (recommended option).
■ Inverter-controlled supply blower
The material supply blower is inverter-controlled, making it possible to adjust transport speed so as to minimize material damage and dust generation. For specifications, contact us.
■ Pellet tank KV-5
Tank for stocking virgin optical resin material.
Pellet tank KA/KV/KX
■ Line filter GX-10-002
A line filter can be installed on the molding machine hopper to thoroughly remove dust.
Line filter GF/GX
■ Hoses
Specify the length of the bare stainless steel flexible hose used to convey stock. (Ferrule ends, 0.5 m markings from 1 -- 4 m, lengths over 4 m possible by connection) Suction hoses of the same length as material hoses are automatically selected.
■ Weekly timer
Machines can be started and stopped automatically by simply setting the days of the week and times that the machine should run.
■ Warning lamp
Integrated signal lamp (red) for signaling overloads or temperature errors. Incorporates warning circuitry.
■Attachment
Purpose-specific attachments are available.
