Optical Resin Dehumidifying Dryer

High performance contamination-free dryer
for molding optical products

- Applicable with N2 gas circulation
- Class 150 clean factor inside of dying drum
- NX Round System that delivers thorough drying and impurity removal
  via an airtight structure and multiple-stage filter
- Heatless dry air unit that delivers cryogenic dehumidification
  at –50˚C and maintenance-free operation
- Energy-savings and stable temperature control
  using ceramic heaters and SSC control
- Lineup of dedicated KX series pellet tanks
  for maintaining cleanliness with optical resins

A Class 150 clean factor means that
  only 150 suspended particles of 0.5 µm in size exist in 1 ft3.
Drying capacity is given for PC drying.
NX Round System

■ NX Round System

The NX Round System incorporates a multiple-stage filter into STOLZ’s Round System that supplies and circulates at a determined flow rate dehumidifying air of –50˚C generated by a heatless dry air unit through a closed system consisting of a completely airtight blower, heater and dryer drum.

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.

Drying performance

■ Exceptional drying performance

No matter which engineering plastic resin is used, the DEZAT NX series demonstrates exceptional drying performance that improves molding precision. Operations can be smoothly resumed from the stopped state, as stock in the drum does not absorb moisture while the system is not running.

Drum internal clean factor transition

■ High clean factor, contamination-free

The drum attains the same Class 150 clean factor standard for clean rooms thanks to a newly developed 3 µm fine-mesh filter element, an originally designed clean valve and #400 polishing of all SUS304 surfaces that come in contact with stock. The NX series dries resins used for precision molding of light guides, lenses and other optical components without allowing contamination, and reduces defects caused by infiltrated foreign matter, hence helping manufacturers to improve their production efficiency.

N2 gas connection port

■ Applicable with N2 gas circulation

An N2 gas connection port (ø9 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.)

■ Easy maintenance

The drying drum is structured with wide openings at the top and side so that stock loading and maintenance are speedy and easy.

Line filter GX-10-002
Line filter GX-20-002
Stainless steel flexible hoses

■ 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.

■ Stock feeding to 2 molding machines

The NX series can supply dried resin stock to 2 molding machines using multiple feed branch lines and air branch valves.

■ Line filter

A line filter can be installed on the molding machine hopper to thoroughly remove dust. Applicable models are shown in the table. Specify hose length separately when ordering.

■ Hopper plate and attachment for installation on molding machine

An installation plate and attachment are separately needed to install the hopper on molding machines that do not meet the standard specifications shown in the table, therefore indicate those specifications when ordering.

■ Hoses

Specify the length of the bare stainless steel flexible hose used to convey stock. (Ferrule ends, 0.5 m markings from 1 -- 5 m, lengths over 5 m possible by connection) Suction hoses of the same length as material hoses are automatically selected.

■ Power cable

The standard power cable is 4 m long, but other lengths are available.

■ Color

Provide samples if desiring colors other than the STOLZ standard color (shown in photos).
