Compact Optical Resin Dehumidifying Dryer

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

Drying capacity is given for PC drying.
Round System

■ 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

■ 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).

Pellet tank KV-5
Line filter GX-10-002
Integrated signal tower (Red)

■ 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.


Purpose-specific attachments are available.
